What is the deal with the IDE transfer rates?  Is anybody getting throughput
anywhere close to the platter->controller rate?  I haven't seen anything
even close to the 5MB/sec limit of the IDE interface.  These drives are 1:1
(non-interleaved), aren't they?
Here are the rates I get:
1) sequential read (MSDOS C program that uses bios calls to read 64-sector
blocks sequentially from outside (first) track inward)
8mhz bus    10mhz bus
--------    ---------
MAXTOR LXT340:    860KB/sec   976KB/sec
QUANTUM LPS240:   862KB/sec   887KB/sec
2) disk buffer read (same C program, but re-reads the same block repeatedly
so in effect is reading the RAM buffer on the drive)
8mhz bus    10mhz bus
--------    ---------
MAXTOR LXT340:   1046KB/sec  1212KB/sec
QUANTUM LPS240:  1015KB/sec  1276KB/sec
3) CORETEST V2.7 transfer rate (seems to agree with (2) above)
8mhz bus    10mhz bus
--------    ---------
MAXTOR LXT340:   1051KB/sec  1224KB/sec
QUANTUM LPS240:  1026KB/sec  1298KB/sec
I managed to get hold of the QUANTUM LPS240AT product manual and it goes
into excrutiating detail describing how the bits get from the platter,
through the controller, and out the IDE interface.  Nowhere do I see
anything like "after the bits are whipped of the platter at high speed
they sit around in a buffer to thaw before they are sent to the host"
(even though I SWEAR that's whats happening ;->).  Here are some relevent
quotes from the manual:
"Data is transferred from the disk to the read buffer at a rate of
3.75 MB/s maximum, 1.87MB/s minimum."  (My calculations show 3121KB/sec
maximum and 1578KB/sec minimum...  disk spins at 4306 RPM with 87
sectors per track on the outside and 44 on the inside)
"Single burst errors of up to 24 bits within one sector can be corrected
'on-the-fly', in real time as they occur, allowing a high degree of
data integrity with no impact to the drive's performance."  (I take
this to mean error correction isn't the bottleneck)
"For page-mode operations, the data-transfer rate to and from the buffer
RAM is up to 10.0 MB/s. This high transfer rate allows the AT Interface
IC to communicate over the AT bus at a data-transfer rate of 5.0 MB/s,
while the DCS simultaneously controls disk-to-RAM transfers"
^^^^^^^^^^^^^^
So the thing can even do it's cache pre-fetch WHILE it's sending the
requested sector (it has 3 64KB read buffers for pre-fetching, I guess
you could call that a cache :-|).
So when I do a sequential read on the outer tracks, WHY am I getting a
measly 862KB/sec when I should be getting around 3MB/sec???
Any of you hard-disk engineers out there know?
Wondering why my disks are so slow,
David

I had a problem getting 256 colors (I was stuck with 16) even though
the flex-stuff said I was at 1024-256.  I solved it by entering

| SCSI II Draft Proposal, Rev. 10h, Section 4.2.1: Single-Ended

| implementor's note: " Stub clustering should be avoided. Stubs
| should be spaced at least 0.3 meters apart."
|
| For the non-technical, stubs are SCSI devices. :-)
However, also be aware that Implementor's notes are basicly
recommendations, they are *NOT* part of the spec.  As others have
noted, many vendors (including SGI) violate this.  Indeed, the main
point is to reduce impedance changes, and therefore reflections, and
therefore 'noise' on the bus.

If you have an adequate supply of air moving over the system (most

system without the cover for extended periods without a problem. (I'm
talking about completely removing the cover - not just leaving the slots
uncovered.) HOWEVER, the biggest reason you have a cover to begin with

It's true.  I read about it from an article in ClariNet (can't send it

Well, some quick math on my part shows that an 8.3MHz bus, 16 bits
wide, performing a transfer every two clock cycles will provide 8.3M
bytes/sec.  Someone said that it really takes 3 clock cycles to
perform a transfer, so that reduces the transfer rate to 5.5MB/s,
which is the commonly-used figure for ISA bus speed.  However, I
believe a two-clock transfer is possible (0 wait states).

In addition to startup time, I leave things running because my PC doubles as
a fax machine.
However, this is off the original subject. I didn't get the replies on BIOS,
CMOS, and DOS clock/date logic. All I know is that I've been running this way
for many months and it is only recently, the last month, that I have noticed
the intermittent clock problem. As I stated, it is not always the date that
doesn't roll forward, sometimes I notice that the clock is several minutes
behind where it ought to be.
When unattended, the following are generally running minimized in Win 3.1:
Clock, WinFax Pro 3.0, Print Manager, MS-Word 1.1, File Manager, Program

Hi,
I am buying a Quantum LPS240AT 245 MB hardisk and is deciding a
HDD/FDD controller. Is 32-bit VL-bus HDD/FDD controller faster
than 16 bit IDE HDD/FDD controller card? I hear that
the VL bus controller is SLOWER than a IDE controller?
Which one is true?
Please shed some light by email or post.
Thanks a lot.

The only difference is the time the driver gets loaded. mouse.sys will be
loaded during the config.sys and therefor before the command.com. mouse.com
will be loaded during autoexec.bat and so after the command.com.
> which one is better?
mouse.com could be started from the commandline after the booting and it
could - perhaps - be unloaded, if no other driver is loaded after it.
The working of both drivers is totally the same.
When I ran dos, I preferred loading most of the drivers in autoexec.bat,
because some programs won't run with some drivers and I could choose the
ones I needed during startup. But with DRDOS6, this advantage is gone,
because DRDOS lets you choose in config.sys which drivers should be loaded.

Referring to the manual of my motherboard with AMI-BIOS, 10 beeps are a
'CMOS Shutdown Register Read/Write Error', if the system stops after these
beeps. If the system continues, it is a 'Keyboard error'.

Hi,
I'm currently in the process of writing a number of PD programs
for the sound blaster. The first of which is a CMF voice editor which
is hopefully going to be available soon (as soon as I can get it to
an FTP site).
Anyway the next stage is to use the midi port to enter music and play
the FM synth remotely. The problem is that I have little or no info
on the SB midi port.
I have tried using the Sound blaster freedom project routines, however
this just results in the port locking after a couple of accesses and
loss the of note velocity data byte.
I am using Turbo C and would be grateful for any info or source fragments
may help. When I was in Berlin this summer I saw a book which seemed to
have all this information, but my German is poor to say the least, if anyone
has this book could they please mail me.
My second request for help concerns standard file formats (how can a file
format be standard if you keep it secret ?) I need to know the file format
for instrument bank files *.BNK and Roland music files *.ROL.
Finally does anyone have a source for displaying PCX or GIF files to EGA

I had this problem some time ago.  Some BIOSes do not automatically install
COM3 or COM4 in the port tables. Programs like most modem programs which
write directly to the port work fine but anything that uses a BIOS call
fails. Find a BBS or FTP site where you can get a copy of PORT FINDER. Put
"device=pf.sys" in your config.sys or run pf.com from your autoexec.bat.
This little program will locate all existing ports and make sure the BIOS
tables are updated. It works great. PF will also let you swap ports and
such also if that is of any value to you.

Hi Netters,
As promised, here are the summary of opinions on DoubleDisk Gold v.6.0.
People seem to be quite happy with the product. There is no much of
opinion on how good it is compared to the industry leader Stacker 3.0.
(Superstor Pro is not considered since it is slower than Stacker although
just as reliable - BYTE Magazine's conclusion ;-) ), so it's hard to make
any decision to go with Stacker or with DoubleDisk Gold v6.0.
However, it seems that at $39.95, it is quite a buy.

Hello Buddy,
I do not have DD Gold 6.0 experience.  I just ordered it.  I currently have
DD 2.3 (the last version).  I am very pleased with its performance.
Here is my suggestion...
1)  If you do not have any compression software currently, I would go with
DOS 6.0's compression.  All the discussion on the net indicates that
for $50 you get the compression (built into the OS), plus the other
utilities that you would pay way more than $50 for.  Besides, you
are now at DOS6.0 (whatever that means...)
2)  If you have DoubleDisk 2.3 already (like I do), the cost is $29.95
for the upgrade.  After thinking about it and asking the net, I
decided that I could not go wrong with the update cost!
I have never suffered from performance of DD.  I have a 12ms HD with
large SW packages in both compressed and uncompressed format.  It
works great.  Not delays.  I think the "A" is better than "B"
arguements are a lot of bunk... they are all comparable in performance.
I am looking forward to being able to "LOADHIGH" the DD sw.  That
has been an annoyance.
3)  If you have Stacker, et.al. currently, I would not see it worth the
effort to upgrade.
Just my $.02 ...
Regards,
Mark Bagdy
----------------------------------------------------------------
Buddy,
I got the same mailer. About 2 weeks ago I got DDG and installed it. The
documentation was, in my opinion, easy to follow. I used the automatic
installation (not the custom) and everything went smoothly.
There were some specific instructions on a readme file for dealing with 386max
& QEMM. DDG has an uninstall (unlike DOS6.0) if you need it. My system has a
203Mb hard drive. before installing DDG I had ~5Mb free. After DDG I had
~197Mb free. Pretty good statistics considering that my 8Mb permanent windows
swap file stayed on the uncompressed portion (along with other drivers and
such).
I have had no problems whatsoever. I have noticed no slowdown (other than it
takes a little longer to boot) either in windows or dos. So far I am a very
happy camper.

I have been using DoubleDisk Gold for a little more than a month on
a 486DX 33Mhz, 120MB Seagate drive, running DOS & Windows in 386 enhanced
mode.
I ran some tests and concluded that the speed of a DoubleDisk drive
with a drive read cache is about equal to the bare drive without a cache.
I have no complaints about reliability.  It was very easy to install.
The only problem I had was with Castle Wolfenstein 3-D.  I assumed the game
was trying to bypass DOS disk access and moved the game to the non-compressed
region of the disk.  Since then the game has never given me a problem.
There was never any damage to the DoubleDisk drive.
Compression performance for the whole disk has held steady
around 1.8:1.  This is lower than expected but about 20% (size) of my files
are compressed image files and some large zip files.
If you have any more specific questions let me know.
Dan
---------------------------------------------------------------------------
I bought it an have been happy with it.  I use it on both MFM and IDE 40
MB drives.  I was using DoubleDisk before Gold came out.  That is the
same product MSDOS 6.0 is shipping with.  No problems with either
product.

you  need to massage few switches in your system.ini.
in the virtual memory section, flip the 32bitaccess switch on and the
associated driver (wdctl or some such) switch on.  this will enable
32bit access, but be sure you can use it, as not all hard drives
and controllers support it !

I thought this was a neat feature until I noticed that
when an image is re-sized, the scanning frequency is
necessarily changed.  This causes digital multiscan
monitors like my MAG MX17F to get confused as to which
mode to use if the frequency gets too far from the
standard selections.  For this reason, I use the
"factory defaults" for position/size on the ATI card
and adjust each mode individually (only the first time)
at the monitor.  The MAG (and many other multiscan
monitors) has (have) the ability to recall these settings
the next time each mode is "detected".

Hey folks.
Is it possible to short out your CMOS chip?  I think mine is fried.
These are the symptoms...
I have to do the following to get my computer (a Gateway 486DX33)
to boot...
Turn the power off
Disconnect the battery to the CMOS chip
Turn the power on
Get into setup upon getting the CMOS configuration error
Set up the CMOS
Exit the setup with [F10]  (phoenix bios)
Ignore the diskette 0 seek error and press [F1]
The computer then boots normally.  Both hard drives are accessible
but the floppy drives are not.
I can back up over the network and such, but if I need to reboot,
I have to turn off the computer and repeat the steps above.  If I
simply <Ctl>-<Alt>-<Del>, the computer hangs after the memory test.
Does this sound like the CMOS chip is fried?  Can I buy another one?
Where?
Thank you for your kind attention.

Organization: Motorola Inc, Austin, Texas
Lines: 47
For those of you who might be familiar with Insight Distribution
Network, Inc. and their Multimedia Kits:
I'm seriously considering buying the Insight Talon TA-2000 MM Kit, which
is bundled with the CD-ROM drive with 265-280ms access time, 300Kb dtr,
multispin, multi-session Photo CD capability, etc., and with the PAS-16
sound card, etc.... (if you are familiar with Insight, you know the kit
I mean).  I believe the drive is either a Texel (265ms) or an NEC
(280ms), but it is not clear to me which one is actually a part of the
bundle (at least two of their sales people couldn't give me a straight
answer as to which one; ah, yes, one of the drawbacks of OEM!).
Other questions:
- Excuse my ignorance, but is "Texel" a reputable maker in the CD-ROM
market?  Or do you think NEC is the better drive?
- Bottom line:  Is this kit worth the money?  (Currently, $449 for the
TA-1000, and $699 for the TA-2000)
Alternatively, I was thinking that the TA-2000 might be overkill for my
uses (however, I *do* want full multimedia capabilities, Photo CD stuff,
educational programs for my kids, etc.), and considered the lower-end
TA-1000 kit and using the difference (around $250.00) to get something
else useful, like a tape back-up drive unit.
Basically, I would just like to hear from those who have actually USED
these kits, and whatever pros/cons you might advise, preferably
directly to the email address below.
Thanks,
Koji

Currently it gets so hot that I can not hold a finger on it for more than

I keep a big fan blowing on it, but am considering using a heat sink.

I just installed a DX2-66 CPU in a clone motherboard, and tried mounting a CPU
cooler on the chip.  After about 1/2 hour, the weight of the cooler was enough
to dislodge the CPU from its mount.  It ended up bending a few pins
on the CPU, but luckily the power was not on yet.  I ended up
pressing the CPU deeply into its socket and then putting the CPU
cooler back on.  So far so good.
Have others had this problem?  How do you ensure that the weight of
the CPU fan and heatsink do not eventually work the CPU out of its
socket when mounting the motherboard in a vertical case?

I believe that any VL/EISA/ISA motherboard that uses the HINT chipset
is limited to 24-bit EISA DMA (where 'real' EISA DMA is 32-bit).  The
HINT EISA DMA has the 16 mb ram addressing limitation of ISA.  For this
reason I would pass.  I own one of these (HAWK VL/EISA/ISA) and am look-
ing to replace it for exactly this reason.
Please double-check me on this.  In other words, call the motherboard
manufacturer and ask them if the motherboard supports true 32-bit EISA
DMA.
Other than this limitation, the motherboard works quite well (I am using
mine with DOS 5, Windows 3.1, and UNIX S5R3.2).  Also with Adaptec 1742a
EISA SCSI host adapter.

No.  In a standard ISA bus, the one that almost all non-laptop PCs use,
two separate interface cards cannot share an interrupt.  This is due to
a screwup in the bus design.  For example, if your Soundblaster wants
to drive interrupt number 7, then it must hold a certain bus wire to 0
or 1 at all times, depending on whether or not it wants an interrupt.
This precludes letting another card assert interrupt number 7.
When two or more devices in an ISA bus PC share an interrupt, it's
because they're implemented by a single card.

This is not the case: the ROM on the P9000 supports VESA modes of up to
1024x768 in 256 colors.  VESA-compliant applications should have no trouble
setting these modes. (But I'm forwarding your posting to our Software group,
just in case.  Can't be too careful.)  Not that I doubt that YOUR applications
are failing to run; lots of stuff depends on figuring out which exact SVGA
they're looking at, and don't use VESA calls (VESA is still pretty new).
Every new chip set confuses them.

I think we go to AT LEAST 76 Hz at 1024x768x8, and maybe more (and
it's a function of the RAMDAC speed, not the Power 9000). We need to
fix the problems you've noted (they were already on the list).  If
you're really interested, though, take a look at the text file
P9000RES.DAT, which holds the data from which the choices in the
P9000 monitor installation program are built.  Working by analogy,
you can build up a new monitor definition that has the right
combinations of refresh rates for your monitors.  Keep a backup copy
of the file!  Once you've built a new version of the P9000RES.DAT
file, run the P9000 installation program, INST, and your new choices
should show up.  (This assumes you have the WEITEK v. 2.2 drivers.
You can tell the rev number by looking at the modification time of
the driver: 02:20 is version 2.20.  Microsoft uses this gimmick,
too.)

The SPEEDY benchmark was put out by Hercules and IIT, who to my
knowledge were unencumbered by any motivations except making the
Hercules Graphite/IIT AGX014 card look really good.  So I'd take the
numbers with a ton of salt. (Texas Instruments did the same thing
with WINTACH, trying to make the 34020 look good compared to the
8514, as if anyone cared.)  It's safer (though not safe) to use
benchmarks from "unbiased" sources, such as testing labs, columnists,
etc.

I think you'll a large discrepancy between the results of SPEEDY and
the results of anything else in the universe on these things.

Font caching is a perfectly legitimate optimization -- Windows has
hooks for it built right into the GDI.  What's kind of silly is IIT's
use of a hardwired "The quick brown fox jumped over the lazy dog then
sat on a tack" string in their driver.  Not only is it useless in
real applications, it lacks the programming elegance of the "Bart
Simpson optimization," in which you save the bitmap of the
most-recently drawn string in off-screen memory, and just do a
screen-to-screen bitblit if you happen to be given that same string a
second time in a row.  (We call it the "Bart Simpson optimization"
because Bart's the only person we can see benefiting from it: he
could right "I will not cheat on benchmarks" a hundred times and be
done in half the time it would take to actually form each character.)

Subject: Do the 2MB ATI Ultra Pro 16 and 24 bit Windows Drivers Work?
Organization: University of Texas at Austin
Lines: 35
Hi there.  We just bought a 486 DX2/66 Gateway system with a 2 meg ATI
Ultra Pro video card.  Everything seems to work fine except for the
Windows Drivers for 800x600 24 bit, and 800x600 and 1024x768 16 bit
modes.  The fonts and icons start deteriorating after windows startup,
and within minutes of use, everything on the screen is totally
unintelligible.  Naturally, I called Gateway tech support to inquire
about this.  The technician asked me about the drivers, and I told him it
was version 1.5, build 59.  He told me that the 16 and 24 bit drivers for
the ATI Ultra Pro simply do not work!!!  Is this true?  If so, I'm simply
amazed.  How could this be?  The strange thing is I would have expected
to see some discussion on here (unless the subject has made the FAQ!!!).
One very suspicious point that came up later was that he stated that none
of the Windows Accelerator boards have working 16 and/or 24 bit drivers
for Windows 3.1.  I easily challenged him on that because I've been
running a Diamond 24x in 15 bit mode at home for 4 months now, and I have
tested and used the 24 bit mode as well.  He then backed off and said:
"Well, Diamond has been working on those drivers much longer."  Anyway, I
just wanted to see if anyone else had any trouble and what they did about
it.  Any feedback will be appreciated.
The system configuration is:
Gateway 486 DX2/66 Local Bus
16 Megs Ram
SCSI HD & CD-ROM
Ultrastor 34F Local Bus SCSI controller
ATI Ultra Pro Local Bus with 2MB VRAM
DOS 6.0
Windows 3.1

Hi!
One of the ASPI-drivers (I think it's the ASPICD) supports a /NORST

Experiences with Diamond Viper VLB video card
Several problems:
1) The ad specified 16.7 million colors at 640x480 resolution with 1MB
of VRAM, which is what I have. This color depth is NOT SUPPORTED
with video BIOS version 1.00 and drivers version 1.01. A max of 65K
colors are supported at 640x800 and 800x600 resolutions with 1MB
VRAM.
2) With the 65K color choice I notice two minor irritations:
a) Under NDW, when an entry in a list is highlighted (such as in an
Open menu) and then is deselected, a faint vertical line often
remains where the left edge of the highlighted rectangle used to
be.
b) With Word for Windows, when you use shading in a table, the
display shows the INVERSE of the shading; for example, if you
shade the cell as 10%, the display is 90% (the printout is OK).
3) The big killer bug is using the Borland C++ Integrated Development
Environment. The problem occurs when you click on the Turbo Debugger
icon (or use the Debugger option in the Run command), and the
debugger application goes to VGA character mode (as it is designed
to do). The screen goes haywire, and is largely unreadable. The
Turbo Debugger display is all garbled.
Through trial and error, I have found that when the disrupted screen
is displayed you should do [Alt-Spacebar] followed by the letter
"R". This instructs Turbo Debugger to refresh the screen, and it
does this satisfactorily. I wish I didn't have to do this.
The bug is more than with the Diamond drivers. The same disruptive
behavior happens with the standard VGA driver that comes with
Windows. There must be something in the video card that mishandles
the VGA mode.
The problem is not my monitor. The same bug shows up when I use
another monitor in place of my usual one.
I still like this video card, and am hoping its problems will be
remedied (they do offer a 5 year warranty).

The --VERY VERY FIRST-- thing you do is make sure that --ALL-- files on
the floppies that you can currently read in the drive, which aren't
already on your HD or another floppy (if you have -two- floppy drives)
get copied to your HD (and/or to a floppy in your other drive).
If you don't do this before fixing the alignment problem you have kissd
those files goodbye.  (Well, you can -try- to re-misalign the drive back
to read your floppies, but don't count on be able to do so!)
Generally, head alignment is something I'd only trust to a good repair
shop (though there are/have been DIY guides).

No, VL-bus IDE is no faster than ISA IDE.  The IDE interface is
fundamentally nothing more than an extension of the ISA bus, and if
you hook it to VL-bus it'll work as fast as the slower of the two,

I need some help with a multi port serial board of unknown origin.  I'm
hoping someone knows what this board is, or, even better, what the various
switches and jumbers are used for.
Anyway, here's  description of the card:  It is a 16-bit card, although
I noticed that none of the contacts in the 16-bit extension are connected
to anything.  It has 4 NS16550AN chips in sockets, and 4 corresponding
connecters labeled COM1 - COM4.  There is also an external female connector
with 37 pins.  There are 8 banks of 8 switches, 2 banks of 4 switches, and
7 jumpers.  I believe that I have determined, by following traces, that
SW5 and SW6 (12 switches in all) control the interrupt level for each of
the COM ports.  SW5[1-4] are for IRQ3, SW5[5-8] are for IRQ4, and SW6[1-4]
are for IRQ5.  The other switches are beyond my meager ability to follow.
The only identification printed on the board is "MULTI SERIAL PORT BOARD"
across the bottom.  There is a box for serial number, but it is blank.
Immediately below the words "SERIAL NO", but not in the box left for
the S/N, are the numbers "1990 2 8".
Anyone have any clues?  Your help is greatly appreciated.

Have you checked: 1/ The setting of drive A: to 1.44 M floppy.
2/ The setting of drive B: to 1.2 M foppy.
3/ The cable connecting the two drives to
the controller card (I can't remember which

which is drive A: & b:).

Actually, it does make a reasonable amount of sense. Fixed disk
sectors are buffered by the controller, and transferring them to
memory with a 'rep insw' (or whatever the instruction is called) is
quite efficient (single instruction, goes as fast as the
controller/cpu know how to use the bus). Since the 286 wasn't cached,
the bus is likely a critical resource relative to CPU performance, and
it's possible that DMA bus interference would cause as much or more
loss of CPU cycles (for 'computing') as does the 'rep insw' sequence.
The floppy, on the other hand, is not buffered, so that using the CPU
for floppy data transfer (as was done on the PC Jr, by the way) really
does stink.

There are two 'problems':
(1) the BIOS TOD routine which updates the BIOS clock uses only 1 bit
for day increment, so a second wrapping of the clock past midnight
will get lost if no one calls the BIOS to read the clock in the
meantime, and
(2) the BIOS resets the day wrap indicator on the first 'get date'
call from ANYBODY (after the wrap indicator has been set). So
unless the first BIOS 'get date' call after midnight is done by
the DOS 'kernel' (which is the only part of DOS which knows how to
increment the date, the day wrap indication is normally lost.
My guess is that Kevin's 'menu' system uses BIOS calls to read the
clock (in order to display the time), and is hence the entity which
causes the day wrap indication to get lost. Even if the 'menu' system
'notices' the day 'wrap' (which I think is indicated by a non-zero
value in AL), there really isn't any particularly good way to tell DOS
about it, so that DOS can update the day. The menu system 'should' use
DOS calls to get the time, which would cause the DOS 'kernel' to do
the BIOS call, and the wrap indicator would hence be processed
properly.  Possibly, though, the 'menu' system can't easily use DOS
calls for time, because DOS is not reentrant, and perhaps time
incrementing ofters occur while the 'menu' system is 'inside' some
other DOS call.

You might try asking on one of the comp.sys.ibm.* echos (the best one
may be comp.sys.ibm.pc.hardware).  I say this because the conversion
seems more geared toward a PC user wanting to use that monitor, than
an Atari user who already can use the monitor (unless maybe they
want to really go wild - converting the monitor to VGA, then
using it as a VGA monitor with a Falcon :-)
As for graphics cards, assuming that the Atari monitor can be
modified/adapted to handle VGA signals, you should probably be able
to use any VGA card (at least with a res around 640x400).  I haven't
tried this, but that would be my guess...

...you might want to price mono VGA monitors anyways - it may be cheaper
to go that route than to do the conversion; besides, with the Falcon and

Is it possible to buy a serial I/O card with the 16550 UART's built in
(rather than having to buy them separately, and socketing them in)?
My current I/O card uses 8250's (correct number? The braindead ones anyway).
It also controls two floppy drives, and two IDE hard drives.
Ideally, I'd like to get a new multi I/O card, that had 2 serial ports with
16550's and could also control another 2 IDE HD's. It would have to have
configurable addresses for both the serial ports, and the IDE controller, so
it could co-exist with my existing card.
Does such a beast exist? Now the hard part - where can I get one in Australia,
preferably Brisbane?

This may be a very naive question but is there any basis for the
claim that a CPU will get hotter when a computationally intensive
job is running? My friend claims that there will be little difference
in the temperature of an idle CPU and a CPU running a computationally
intensive job.

I would appreciate the driver name from CICA which functions as a 256
color driver for a Quadtel video card. The type of chip or chipset used
would suffice as well.

i've been using an identical setup, except for the tower config,
for several months now.  from previous discussions on the net,
the first thing to check for is DMA conflicts with other devices,
especically if you've got any funky ones.  next off, suspect
your tape - try a fresh one.  good luck !

From a recent BYTE magazine i got the following:
[Question and part of the answer deleted]
If you are handy with a soldering iron, the loopback plugs are easy to
make.  On a serial RS-232 nine-pin port, use a female DB-9 connector and
connect pins 1 to 7 to 8; 2 to 3; and 4 to 6 to 9.  For serial RS-232
25-pin ports, you'll need a female DB-25 connector with pins 1 to 7;
2 to 3; 4 to 5 to 8; 6 to 11 to 20 to 22; 15 to 17 to 23; and 18 to 25
connected.  To test a Centronics 25-pin parallel port, you'll need to
connect pins 1 to 13; 2 to 15; 10 to 16; 11 to 17; and 12 to 14 in a male
DB-25 connector.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
There is explicitly NO WARRANTY
that the given settings are correct or harmless. (I only collect, I do
not check for myself!!!). There is always the possibility that the
settings may destroy your hardware!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Since I hope however that only well-minded people undergo the effort of
posting their settings the chance of applicability exists. If you should
agree or disagree with some setting, let me know immediately in order
to update the list.
If you possess a HD not mentioned here of which you know BIOS and/or
jumper settings, please mail them to me for the next update of the list!
Only IDE (AT-Bus) Harddisks will be accounted for.
If not specified the Landing Zone should be set equal to the number of
cylinders. If not specified the 'Write Precompensation' should be set
65535. (There are BIOSes that don't even ask for it).
Another statement (maybe right):
IDE harddisk don't have Precomp and LZone. The precomp is a built-in parameter
and lzone isn't used because most if not every IDE disk has autopark.
The jumpers' names are given as printed on the HD's board, often only a
jumper number (JP12 means the jumper '12'). A zero means that the jumper
is left open, a one means that the jumper is closed.

numbered (left to right) J16 - J20  , and the set of 4 is numbered
(bottom to top) J22-J25.
The only jumper of normal interest is J20. Jumper it for only
drive in a single drive system, or master drive in a dual drive
system.
Remove the jumper J20 for slave drive in a dual drive system.
J19 is a dummy and may be used to store the spare shunt if the
drive is configured for a slave mode.
Jumpers J17, J18, J24, J25 are factory reserved. Abnormal operation
may occur if jumpered.

Link Options
In order to install the Rodime Ro 3000A series drives the dumpers for
the single/dual drive and LED operation on the drive need to be set as
described in the relevant product specification.
I a single drive environment the drive is described as a Master.
In a dual drive environment the drives are described as a Master and a
Slave. This is due to the protocal the takes place between the two drives
when performing diagnostics.
There are four links, LK1, LK2, LK4 and LK5, adjacent to the 40 way
interface connector. They have the following functions and are described
in order as viewed from the end of the drive, with the first jumper
described nearest the 40 way interface connector.
LK2: LED
When fitted, this jumper connects the LED drive to pin 39 of the
interface. This allows a LED to be connected to the interface. An
external current limiting resistor needs to be fitted in series with
the LED when this option is selected. The value of the resistor will
be dependant on the LED type chosen but will be in the range of 130
Ohms ot 220 Ohms.
LK1: Dual Drives
This jumper must be fitted when two drives are attached to a single
bus. It fallows communication across the 40 way interface connector,
indicating, to the Master drive, the presence of a Slave.
LK4: Master
When fitted this signifies that the drive jumpered is a Master. If
there are two drives connected on a single bus then only one may be
jumpered in this way.
LK5: IOChRdy
When fitted this connects the IOChRdy signal to the drive, it is
fitted when the drive is used in host systems that have a higher
data transfer rate than the drive i.e. greater than 4 MBytes per
second when using 1:1 interleave. This jumper is not normally
fitted as most hosts transfer at a lower rate than 4 MBytes per
second.
There are four possible Master/Slave configurations in which a drive(s)
may be jumpered:
Master, single drive with LED on interface		LK2 & LK4 fitted.
Master, single drive without LED on interface	LK4 only fitted.
Master, dual drive without LED on interface	LK4 & LK1 fitted.
Slave, dual drive without LED on interface		No jumpers fitted.
Master, dual drive with LED on interface		LK4, LK1 & LK2 fitted.
Slave, dual drive with LED on interface		LK2 only fitted.
The Master drive will delay power-up for approximately two seconds to
reduce power surges in applications where dual drives are used.
The other connections for a LED will be found close to the 28 way
connector at the other end of the drive. This LED driver is not affected
by the link options. An internal current limiting resistor is on the
drive for this LED driver. Refer to the product specification for further
details.

Subject: Parity Error - System Halted /anyone have any ideas?
Organization: Illinois Institute of Technology, Chicago
Lines: 28
I recently bought an AMD 386/40.  The motherboard booklet says
the board is a "391 WB/H."  I have 4 1x3 simms on board.  The machine
also uses a Super IDE I/O Card (model PT-604). (of course niether
the motherboard or the I/O card booklet clearly state who the manufacurers
are) I'm also using a Trident 8900C SVGA card.
Anyway, that's all of the pertinent info I can think of.
My problem is that the computer often freezes or displays "Parity Error --
System Halted" messages depending on whether I set the Memory Parity Error
Checking to "disabled" or "enabled" in the setup of the bios (makes sense).
Its AMI bios (so it must be an AMI board?).
I just took it back to the dealer and they replaced all of the
SIMMS but I keep getting the same error (more frequently now).  It all
worked at the dealer and didn't start screwing up 'till I got home (figures).
I've tried to take out all of the SIMMS and even re-inserted them
in reverse order, making sure that the connections were solid.
My suspicion jumps to this damn all in one HD controller/serial/
parallel/game-port I/O card, or to the motherboard (God forbid).
CAN ANYONE HELP?
Thanks, Peace,

Cyrix have released a 386 pin-conpatible 486 clone. Designed to upgrade
old 16 & 20MHz 386's the chips are also clockdoubling. Thus a 16MHz 386
can be transformed into a 32MHz 486, with a single chip upgrade.
Unfortunately in Australia the DRu2 sells for $700A (16MHz) and $1000A
(20MHz), about 1.5x the price of a 486dx33 motherboard with two vlb slots!!!
How much do these thing cost in the States?
How well do they work?

I think it all depends on your motherboard and the cards you have in your system.  Your HD stopped boot probably because your HD controller can't handle the faster BUS speed.  I have a 486-33DX, I set my bus divider to CLK/2.5, that is close to 13MHz.  I can gain singificant performace increase on my Video card and harddisk transfer rate when I boost the bus speed.  And my system work flawlessly under this setting.  And you know what, when I go to CLK/2(17MHz BUS), my HD refuse to boot.

I am no expert on this.  But I am pretty sure there is no way to recover this.  IDE drive has mapping information written directly on drives.  When you  low level format it, the information itself is gone as well, I don't think you can get it back unless you send it back to Western Digital and ask them to refurbish it for you.

I have a question regarding my stack on my pc.  I am programming
in Turbo C 3.0 and my program is rather large (model large too).  I keep
getting errors that I am running out of memory after a while of running the
program. When I compile the program, it says I have 4.45 meg of RAM so
I can't seem to explain why it crashes.
All it is doing is running in a loop while the operator is idle and
after a while of sitting, it will screw up all the variables. This leads
me to believe that my stack is filling up and overflowing.
Does the program take memory up when it is calling void functions
that do not return anything??
I have been working on this problem for days and I would really
appreciate any responce.  If this is not the correct newsgroup, I will
gladly re-post, but this is the only I could find.
Thanks in advance,

I own an 8088 640K clone which does all I want except run 1 game I want
to buy.  The game says it requires a 80286 with 640K.  Game tech. support
says game will run on 8088 but uses a some digitized graphics which would
make it run really *slow* (it's a card game - Hoyles Classic Card Games,
digitized graphics are photos artwork of game fictional card players).
What can I do to speed up how this game would run, short of an 80286
motherboard upgrade.  Co-processor?  Accelerator card mimicking 80286?
My 8088 can run at 10 Mhz.  Any advice would be greatly appreciated.

I don't know the exact meaning of UART, but I think it is something like
Universal Arithmetic Receiver Transmitter. Normally, the older boards have
a 8250 or 16450 UART on board. Those chips generate an IRQ for every char
they received. The 16550 UART has an internal 16 byte buffer, so - with the
right software installed - it generates an IRQ every 16 chars.

If you ran dos, you don't need a 16550, because dos runs only ONE task at a
time and the whole cpu-power could be used for the transfer. But if you are
running a multitasking OS such as OS/2, Unix, etc. ( windows ? :-) ), the
cpu cannot work the whole time with one task.
The result are lost characters or broken transmissions because of timeouts.
> 4) Is it only for internal modems?
NO. The only diffrence is that internal modems have the UART on board,
whereas external modems are connected to the computer over a serial port
which has the UART on board.

I use a Zyxel1496B with a 16550UART under COHERENT 4.0. I'm very satisfied
with it but I think that nearly everyone is satisfied with his own modem.

I just bought a new IDE hard drive for my system to go with the one
I already had.  My problem is this.  My system only had a IDE cable
for one drive, so I had to buy cable with two drive connectors
on it, and consequently have to switch cables.  The problem is,
the new hard drive's manual refers to matching pin 1 on the cable
with both pin 1 on the drive itself and pin 1 on the IDE card.  But
for the life of me I cannot figure out how to tell which way to plug
in the cable to align these.
Secondly, the cable has like a connector at two ends and one between them.
I figure one end goes in the controler and then the other two go into
the drives.  Does it matter which I plug into the "master" drive
and which into the "Slave"?  any help appreciated.  thanks...

I have a 486sx25 computer with a 105 Mg Seagate IDE drive and a controler
built into the motherboard. I want to add a SCSI drive (a quantum prodrive
425F 425 MG formatted). I have no documentation at all and I need your
help!
As I understand it, here is the process of adding such a drive.  Could you
please tell me if I'm right..
1- Buy a SCSI contoler.  Which one? I know Adaptec is good, but they are
kind of expensive.  Are there any good boards in the $100 region? I want
it to be compatible with OS2 and Unix if possible.  Also, I have seen on
the net that there are SCSI and SCSI2 drives. Is this true? Does the
adapter need to be the same as the drive? What type of drive is the
quantum?
2- connect the drive to the adapter via a SCSI cable and the power cable.
Do i have to worry about the power supply? I think I have 200 watts and
all I'm powering are two floppies and the seagate drive.
3- Setup the BIOS to recognize the drive as the second drive.  What type
of drive is this? I don't have the numbers for this drive.
4- Format and create partitions on the drive. Do I use format or fdisk? I
think that IDE drives can't be low-level formatted. Is it the same with
SCSI? How exactly does fdisk work? I have a reduced msdos 5.0 manual
(clone obliges) and there is no mention of fdisk.  Ideally, I would want
the drive partitioned in to two partitions D: and E: how do I do this?
Well that seems to be all. Is there anythiing I'm forgetting?
Any help is *really* appreciated, I'm lost...

the above quote SCSI-1 {SCSI-2 controller chip}
are we talking about a SCSI-1 device (e.g. HD) on a SCSI-2 Controller

are we talking about a SCSI-1 Controller that had a chip upgrade

I ran a 386-33 out of a cardboard box for more than a year with no
major effects (yeah, no case at all, MB sitting on a static bag)
other than the noise from the Poersupply it ran pretty good.
as for cooling problems I bought a 12-14 inch fan and  turned
it on full and set the output directly on the motherboard.
I did finally get a case though and I am still running the parts
with no ill effects.
I also had no kids to spill things on the MB> I had no cat leaving
hair on the MB etc. etc. on and on....
the two major concerns are keeping static away and keeping the MB cool

I was having major memory problems a few monthes ago.
getting parity error - system halted error message in windows.
I ran QA/PLUS, Check It, Diagnose, as well as several shareware
memory checkers. I had a total of 8 meg SIMM in my system.
these store bought/ shareware memory diagnostics either ran fine
without errors or found an error at some address that I couldn't
place on a memory chip. Out of exahperation I came up with
the (now deleted) steps to find bad memory chips. I found 2
(moral : never buy memory stamped "not for sensitive or critical
applications" on the back.
anyway I did filter out all the bad memory chips using
combinations of 4 of the 8 meg chips and creating a RAM drive to
test on. Although it dodn't alleviate my parity error problems
in windows. I did manage to find bad memory chips in this manner
It has NEVER failed to find a bad chip for me. and the commercial/
shareware have always faild me either not finding the error or
pointing to an addreww which I have no idea on what chip it is.
p.s. man my typing stinks today and I don't feel like futzing around with
this line editor.

I believe you are right.  Both SCSI and SCSI-2 support 8 devices on the bus
(normally that would be the host controller and 7 targets) each of which
may have up to 8 logical units (LUNs).

[Tons of stuff deleted on SCSI vs. IDE question...]
Wow, you guys are really going wild on this IDE vs. SCSI thing, and I think
it's great!
Like lots of people, I'd really like to increase my data transfer rate from
the hard drive.  Right now I have a 15ms 210Mb IDE drive (Seagate 1239A), and
what I would say is a standard (not special, no cache I believe) IDE controller
card on my ISA 486-50.
I'm currently thinking about adding another HD, in the 300Mb to 500Mb range.
And I'm thinking hard (you should hear those gears a-grinding in my head)
about buying a SCSI drive (SCSI for the future benefit).  I believe I'm getting
something like 890Kb/sec transfer right now (according to NU).  How would this
number compare if I bought the state-of-the-art SCSI card for my ISA PC, and
the state-of-the-art SCSI hard drive (the wailing-est system I could hope for)?
Obviously money factors into this choice as well as any other, but what would
YOU want to use on your ISA system? And how much would it cost?
Along those lines, what kind of transfer rate could I see with my IDE HD's if I
were to buy the top-of-the-line IDE caching controller for my 200Mb, 15ms HD?
And how much would it cost?
I actually have a PAS-16, and could (what a waste I guess it would be...) hook
up a SCSI HD through it's SCSI port which yields an optimum of 690Kb/sec.
Actually, I have a borrowed 12ms Fujitsu HD hooked up through it now (and
own the Trantor HD drivers for the PAS-16 SCSI port).  Is this SCSI port a
SCSI-2 port?  How could I tell?  Is the Fujitsu 2623A a SCSI-2?  Are all SCSI
HD's SCSI-2?
Thanks for any comments on these rephrased questions.

If you bought your IDE drive from a dealer, you shouldn 't have to
perform a low level format. Even if the 1st HD is already partitioned
into C and D, FDISK will automatically assign the 2 nd HD to D and
change the 2nd partition of 1st drive to E.
Check the jumper settings and CMOS setup, in particular the correct
number of cylinders and tracks

Apple has patented their implementation of regions, which presumably
includes the internal data structure (which has never been officially
documented by Apple).  Apple cannot patent the concept of a region.
I'm guessing that either NuTek reverse-engineered Apple's internal data
structure for regions (I dunno if this would hold up in court), or they
came up with their own data structure.  If it's the latter, then they
won't be able to draw PICT files containing regions.  Besides PICT files,
there aren't many places where regions are stored on disk.  (QuickTime
movies, perhaps?)  As long as the region isn't being stored on disk and
transferred from a Mac to a NuTek clone (or vice versa), it doesn't
matter if NuTek uses a completely different internal data structure.
I remember reading that Apple also has a patent on their ADB hardware,
and that the NuTek clones would therefore be lacking an ADB port.  What
other patents does Apple have on the Mac?

My wife has one of these.  I have not had much chance to fiddle with
it, but in comparison to our Laserwriters with Canon engines, she
complains that the print is too light for her taste.  The difference
is quite apparent even when the print setting on the Select 310 is
adjusted to the darkest possible level.  I don't find it
objectionable, and indeed rather like it, but be warned that some

There's only one physical size for VRAM SIMMs (unlike DRAM SIMMs which
come in many, many sizes and pinouts), although they do come with
differing amounts of VRAM on them.  The ones you need are 256KB SIMMs, are
organized as 128K x 16, and have two 128K x 8 VRAM chips on them.  This is
the only size which the Quadra and Centris machines can use.

Two.

Both SIMM slots must be filled; putting a SIMM in only one slot does
nothing for you.

80 ns for the Q800 and C650, 100 ns for the C610.

There are certain VRAM chip manufacturers whose parts are not compatible
with the Quadra and Centris video hardware.  Make sure that the source you
get them from guarantees compatiblity.  In general, if it works in a Q950,
it will work in a Q800.

I'm assuming that the cabling tells the Mac, at startup, what kind of
monitor is connected.  Now I think I've seen ads in popular Mac
magazines for products (I'm not sure if it's just a monitor, just a
video card, or a package of both) that allow you to change resolutions
on the fly (w/o restarting the Mac).
If you were to buy a 1304, would it be possible to switch back and
forth between Apple 640x480 and Apple 832x624 without restarting the
Mac?  Is this strictly a hardware startup function, or can software
intervene, or does the Mac hardware occasionally probe the cable
setting and switch automatically?

If you write a second time to a CD you need to have multi-session capability to
read the second session.  Whether it is photos or just data or whatever.
Here is a simplified way of looking at it:
The first session has the directory structure burned at some tracks.  The
second session has a newer directory structure, but the first directory still
exists, because you cannot change, only add.  So if you put that in a 'normal'
drive and it will only look to the first directory and think it has found all
data.  Multisession kindof means that the drive will look for the last
directory written to the disc, older systems look only for 'the' directory, not
taking multiple directories into account.

Subject: Disappointed by La Cie
Organization: Univ of Miami IR
Lines: 52
Approximately four months ago, I purchased a Quantum 240LPS HD from La Cie for
$649. After two months, the drive started having problems. First, there were
intermittent freezes, then corrupted files and resources, then Silverlining
5.41 wouldn't even recognize the drive. So I got an RMA from La Cie and
exchanged the new drive for a reconditioned one.
Well, about a month has passed now and the second drive is having problems.
Often, when I boot up my IIsi I get the flashing question mark. Sometimes, if I
then insert the Silverlining (5.42) program I can get it to recognize the drive
by making it scan over and over for drives. At that point I can restart the
IIsi and boot from the HD. I've called La Cie again and they've given me
another RMA. Their tech support people tell me that if Silverlining doesn't see
the drive there's a definite hardware problem.
Given that this is the second bad drive in four months, I asked La Cie to send
me a *new* one, but they said "no." Also, within three weeks after I purchased
my original drive, La Cie dropped the price on it by over $100.
I can accept that a drive (or two) may be bad. And I know that hardware vendors
make a practice of sending reconditioned replacements when they do repairs. And
I understand that the nature of the computer industry lends itself to sudden
price fluctuations. Nevertheless, taken together, the convergence of these
facts/events have left a bad taste in my mouth. (I should have added above that
when I asked La Cie to transfer the contents of my current drive to the one
they will send_I think the data is still in good shape and I'll have to again
reinstall everything from floppies_they said it would cost me $250 for data
recovery.)
It seems to me that reconditioned hardware should be sold as reconditioned at a
discounted price, and that replacements for new hardware gone bad (still
covered under a 90-day warranty) should be new.
I feel a little helpless about all this. I don't mean to necessarily flame La
Cie_their support staff have always been friendly and sometimes even helpful.
But c'mon. Sometimes a little extra customer service goes a long way. (I sent
a letter to La Cie's customer service when the first drive was returned and I
asked them for a credit on the price difference since I had purchased the drive
three weeks before they slashed the price. I told them I would like to apply
the credit toward the purchase of another La Cie product. They didn't even
have the courtesy to reply one way or the other.)
What's the moral of this story? I'm not sure. But I do know I won't buy any
other products from La Cie in the future.
Bill Krauthammer
f2ehg786@umiami.ir.miami.edu
PS Please don't email or post about how good your La Cie product and service
has been. I'm not suggesting that they are not a good company or anything like
that. All I'm saying is that I've had a disappointing experience with them and
I'll be taking my business elsewhere in the future.

>Plot3D[((-2*9000)/(2*3.1416*((x-5000)^2+(y-8000)^2+
>81000000)^1.5))+((-3*9000)/(2*3.1416*((x-10000)^2+
>(y-1000)^2+81000000)^1.5))+((4*2000)/(2*3.1416*
>((x-7000)^2+(y-10000)^2+4000000)^1.5)),
>{x,-5500,19500},{y,-5500,19500},PlotPoints->50]
I was just curious how fast the plot command would be executed on
various Macintosh machines as well as other personal computers and
workstations.  The results are posted below:

Funny how the IIsi running at 25 MHz is slower than other equivalent
machines, lots slower in fact.  Perhaps the version of Mathematica
makes a difference or the fact that not much RAM was allocated.
Another interesting thing is how fast the SGI did it.  Wow.
Basically, though, I wouldn't draw any conclusions from this data.  It
seems that Mathematica's speed is dependant on a lot of variables.  I
was just curious how different machines would measure up.
Well, if you have any questions or if I forgot something, just drop me

There's absolutely no reason why differences in the DRAM access time
_alone_ would cause an incompatibility.  There would have to be another
difference between the SIMMs for there to be a problem.  I've often used
memory of different speeds with no problems whatsoever.  As long as it's
as fast (or faster) than the minimum requirement you should be fine.
Just out of curiosity, did you actually try this and see a problem, or
were you told it wouldn't work and so never tried it?  Also out of
curiosity, do you know exactly who in Cupertino you dealer talked to (as
I'd like to find out what they're basing this recommendation on).

Its a small box, which has a bag inn it , seemingly

The installation instructions are most informative and say, in full,

SO what does this do ? At first I thought it might be a NT to NTX

When Apple came with their demos to Iowa State, I got a chance to run
Speedometer3.1 on some of the new Macs.  Both machines were running
System7.1, had a 14" RGB.  Don't know what the caches were set to.
Neither machine had an FPU  It appears that the Centris610 is quite a
bit faster than the LC III:
Centris610		LCIII
CPU		13.01			6.92
Graf		15.67			7.69
Disk		2.22			2.44
Math		25.57			10.19
P.R. Rating	12.91			6.58
So, there is a comparison.  There is definitely a very noticable speed
difference between these two machines according to Speedometer3.1.

The kit is for an already existing Laserwriter IINTX. It is a ROM
upgrade that replaces the font rasterizer code with the more
efficient, speedier code that first became available in Adobe Type
Manager 1.0.
That software came out after the original NTXes and the so-called
ATM rasterizer is now standard on Postscript printers.

My apologies!  I goofed.  The "quick discharge" option is part of the

this machine is really fast!  The hardware turn-on feature is annoying, but
I got PowerKey from Sophisicated Circuits and it works like a charm.
However, I still have a few complaints:
- when I restart the machine every time, the screen image (the desktop
pattern) jerks up and down for a few times.
- the Quantum 170 drive is noisy
Overall, I highly recommend it:  it is fast, affordable and looks great!

The screws are Torx screws and the tool isn't to hard to find. It's a
matter of finding one with a long enough shaft to do the trick.
No it is not a good idea to take that fan out.  Why because it will
cause stuff to over heat.  Internal hard drives, motherboard...You name

Frankly, I think this model is a screwup.  It does not have PostScriptlevel
2, only has 13 fonts, and does not even have  fine print or photograde, or
grayshare.  Even the 300 model has this!  I am shocked by the kind of

I agree completely, but there was only a refund for people who bought the GC
with a Quadra. I have seen an alpha version of an extension from Apple called
8.24 GC QuickTime Video which offloads QuickTime compression/decompression
from the cpu to the AM29000 on the card. So it seems it can be done even though
in a developer article it states that the GC can't be programmed - but they
asked that any suggestions be sent in anyway...

Not Quite the point to be considdered here!
Fact: If/When Apple release system 7 (or what ever is current at the time
of release) then you will see shortly afterwards Apple no longer producing
Hardware...Look at Next with their NextStep486 to see what happens.
Who is going to pay Apples Prices when they can get the same thing cheaper

No the continued develeopment is because there is becomming less and less
profit in Hardware, So the Next Step (no pun intended...well sort of), is
to make the money in software (look at Microsoft if you think it can't
happen!), after all you can sell multiple pieces of software to ONE
hardware platform.
As you also said Windows is a nightmare for programmers, so will the
temptation to sell system 7 to a couple of MILLION dos users be too much
for Apple! (50 million copies @ $100 is SERIOUS money!).

Shure it is temperature dependent, but this does not clean all your
problems.
Based on some exp. I must say that the connections between the power supply
and the Monitor and Main Board are usable to this failure, Ram simms can be
badly connected due to some corrosion and the powersupply can be in the
last
phase (lower Voltage).
So you can do following if you are used to such technical terms.
1) Clean all mentioned contacts with contact spray
2) readjust the 5 Volt level of your powersupply
3) use a calm fan and think of preventing dust blowin� through the floppy!
(a fixed piece of paper can prevent this)
if you don't know how to do it beg a friendly technician!

Nec Toshiba and Sony (Apple) nearly deliver the same speed.

The IIvx...LCIII performance at a Centris 610 price. The only reason
to get an IIvx is if you really need the full-size Nubus slots. Keep
in mind that the 610 supports all Apple monitors and has optional Ethernet.
This lessens (but doesn't eliminate) the need for Nubus cards. And unless
you're running FPU-intensive software, the 610 will blow the doors off the
LCIII and the IIvx. The LCIII, on the other hand, is sufficient for most
people and has a great price.
If you haven't guessed, I find halving the bus clock (the IIvx 32MHz uP vs.
16MHz bus) a throughly bad thing and I hope Apple never does it again.

Subject: Adapter Cable for VGA Monitors
Lines: 51
Does anyone know who makes a cable or adapter that is wired according to
Apple's specs that forces the external output on LC's and the Powerbook's
160/180 and Duo 230 into a true VGA style output signal? The NEC Adapter does
not do this since their monitors are multisync they just route the signal into
the correct pinout but do not switch the Macs output into VGA mode.
Do I have to make one of these or does someone already have one made-up??
The following is the Apple spec for the LC cpu VGA Cable adapter. I'm assuming
that the Powerbooks/Duos will work with the same adapter(?);
Macintosh LC to VGA
The Macintosh LC can supply a 640 x 480, VGA timed signal for use with VGA
monitors by using an adapter cable.  The standard Macintosh LC supports VGA to
16 colors, and with the optional 512K VRAM SIMM, the VGA monitor is supported
to 256 colors.
Note:     The Macintosh LC supplies signals capable of driving TTL level
inputs.  However, some low impedance input VGA monitors do not work
with the Macintosh LC.
To connect a Macintosh LC to a VGA monitor, you need to make an adapter cable
from the Macintosh LC video connector to the VGA monitor.  Following is the
pinout description for the adapter cable:
Macintosh LC        VGA
Video Connector     Pin     Signal Name
---------------     ----    -----------
1                   6       Red ground
2                   1       Red video signal
5                   2       Green video signal
6                   7       Green ground
9                   3       Blue video signal
13                  8       Blue ground
15                  13      /HSYNC
12                  14      /VSYNC
14                  10      HSYNC ground
7,10                nc      SENSE1 & SENSE2 tied together
VGA monitors are identified by shorting pin 7 to pin 10 on the Macintosh LC
video connector.  The Macintosh LC grounds pin 7 on its video connector, which
results in pulling down pin 10 and gives the correct monitor ID for a VGA
monitor.

I have a Radius Precision Color 24x video card for the Mac that fits in a
NuBus slot.  The card has 3 Mb of VRAM on it, which means that 24-bit color
is possible on the card!  The card supports just about any monitor scan
rate you can think of (I used it at 640x480, 800x600 and 1024x768, but it
can go higher).  You can switch resolutions and depth on the fly with a
software control panel.
This is the ACCELERATED version of the card, which means all QuickDraw
calls are not executed by the CPU but taken over by the video card, freeing
up the mac processor for other tasks.
The cheapest I could find this card for when I called around last night
was $1738 at Mac's Place.  I will sell it for $1250 + shipping.  It is just
over a year old and never been any problem.  It comes with software and the
original manuals.

I've got the official word on the LaserWriter Pro 600 memory
upgrade.
I just got off of the phone with the quite friendly Donna Rossi
at Apple Customer Assistance.  She tells me that those who
purchased the LaserWriter Pro 600 in a 4 megabyte (300dpi, no
greyscale) configuration should contact their original dealers
who are supposed provide the 4-meg memory upgrade.  For those
who don't know, the extra 4-meg will allow printing at 600dpi
or greyscale (at 300dpi).
If the dealers have questions, they should be directed to their
hardware support numbers and/or Apple Customer Assistance
1-800-776-2333, 408-996-1010 (corporate number).
Regards,
Glenn
P.S. - personally, I'm annoyed at our school bookstore.  They
really have an obligation to provide this information to all
of the customers who purchased the 600 in the original
configuration (they have the records...that's why they ask for
things like a phone number).  When I get my upgrade completed,
I'm going to write Apple and complain.

From the benchmarks I've seen (was that in MacUser or MacWeek?) the FPU-less
Centris 610 is _faster_ at floating-point operations (the kind of calculations
that get routed to an FPU) than a Mac IIfx!
And a Mac IIfx (68030 @ 40MHz + FPU) is _the_ fastest 030-based Mac.
Take note, of course, that benchmarks never tell the whole story... Get your
favorite program(s) and run them on both machines at the store.  They should
let you do that before you plunk down a hefty amount...

Because SCSI works well with removable media, and works well with large

it doesn't have any hooks for dealing with the latter... you'd have to kludge
it. Plus, it's extremely low performance. AND, SCSI has gobs of room for
expansion compared with a floppy (I can just see it, let's stick a 5.25",
a 3.5", a tape drive, and a MO drive, all on the floppy interface. The

Well, I just got my Centris 610 yesterday.  It took just over two
weeks from placing the order.  The dealer (Rutgers computer store)
appologized because Apple made a substitution on my order.  I ordered
the one without ethernet, but they substituted one _with_ ethernet.
He wanted to know if that would be "alright with me"!!!  They must
be backlogged on Centri w/out ethernet so they're just shipping them
with!
Anyway, I'm very happy with the 610 with a few exceptions.
Being nosy, I decided to open it up _before_ powering it on for the first
time.  The SCSI cable to the hard drive was only partially connected
(must have come loose in shipping).  No big deal, but I would have been
pissed if I tried to boot it and it wouldn't come up!
The hard drive also has an annoying high pitched whine.  I've
heard apple will exchange it if you complain, so I might try to get
it swapped.
I am also dissappionted by the lack of soft power-on/off.  This
wasn't mentioned in any of the literature I saw.  Also, the location
of the reset/interupt buttons is awful.  Having keyboard control for
these functions was much more convenient.
Oh, and the screen seems tojump in a wierd way on power-up.
I've seen this mentioned by others, so it must be a...feature...
Anyway, above all, it's fast.  A great machine at a great price!

You must not have tried very hard. I just opend mine in about 2

Well, if you don't match up the pins correctly you will have some

It isn't Apple's responsibility to tell its customers how to fool
around with it's hardware. That is what Apple Service Techs get paid to
do. I personally like the design of the Q800, and applaud Apple for
coming up with a good way to make use of the front space for all of
those drive bays. I like it a lot better than the 900/950 design, except
for those people who need Drive Arrays. I do, however, agree with you
about the LW Pro design.

Again, its's not Apple's place to make it easy for non-certified
service people to fool around with Apple hardware, even if they did buy
it. Of course you are free to do what you want to your Mac, just don't
get upset when your Apple Service Rep tells you that your warranty is no

This sounds like the kind of problem I had when I installed 4MB
SIMMs into an LC, back before low-profile 4MB SIMMs were readily
available. The standard 4MB SIMMs would contact the top of the case and
make it a bit difficult to close the LC, but it did close and work just
fine. One of the nice things about Logic-Boards is that they are
generally quite flexible and can withstand a fair amount of pressure.

Get your facts straight before you post something like this.  The Duo
Dock does not have a CPU of its own.  It is a docking station with
ports connecting various components, including the portable PowerBook
with its own CPU.  I guess these rumored new Duo Docks have a built-in
CPU to perform functions of their own.  Interesting!  If they're not
compatible with the current Duo models, I think you'll be hearing a
lot more "screwed by Apple" complaints.  Imagine a company obsoleting

I thought NEC and Toshiba CD-ROM mechanism have an average
access time of less than 200 ms.  While the SONY-APPLE CD-ROM
drive has an access time of 300 ms for the doublespin models.

I can only comment on thermal recalibration in general. Some new
drives perform it in order to increase overall integrity of data
writes. Basically, the firmware instructs the actuator to perform
a test to see if the data tracks are within a certain physical
tolerance, since when the media heats up or cools down, *some*
track drift is inevitable, and the drive has to monitor it. This
becomes especially critical at very high recording densities, and
so was used primarily on very large-capacity mechanisms, but it
seems to be finding its way into more smaller drives as a way of
boosting the drive's long-term reliability and MTBF ratings.
I first became aware of thermal recalibration when it was pointed
out that the technique conflicts with prolonged write times when
digitizing, say, audio or video to hard disk. Some manufacturers
explicitly state that drives with thermal recalibration are NOT
to be used for applications that have prolonged disk writes.
Hope this helps.

I'm interested in getting an external hard drive for my SE/30.  I've
got an internal 40MB that's pretty full, even with compression s/w.
Alot of people talk about $/MB, what's a good ratio?  I'm thinking of adding
either an 80 or a 100 (or 105).  What brands would people suggest?  Finally,
places to buy from?  Are more popular mail-order places better to order from
or the places that JUST sell hard drives (e.g. ones that advertise in the back
of MacWorld and MacUser).
Thanks in advance.  If e-mail replies are sent, I'll compile them and post
them.

Well, although this may be an uncommon occurrence (or not) I had a "bad"
experience with TechWorks.  This past summer I upgraded (increased) the memory in
a powerbook and a ci.   When I called to place the order for the PB RAM, I was
told by the sales person that they would give me a $50 rebate if I would return
the original RAM (which was also TechWorks RAM.)  I followed the instructions for
returning the old RAM, expecting to see a credit on my VISA within a few weeks.
Well, months went by, and no credit.  After many calls (almost none of which were
ever returned - arghhh) I finally found someone who told me "Why we never
received your old chips."  I then explained I the procedure that I had
followed to return them, to which the person replied "You mean you sent them
US Mail?" (which I had, per the original sales person's instructions.)  I was
told that they their loss of US mail shipments is not uncommon (come on) and that
I should have sent the stuff via FedEx, etc.  I reasoned that I had done exactly
what I had been told to, but they would not budge, the people I spoke with were
absolutely no help.  I sent letters, copies of the original receipts, attempted
to trace the package through the US mail, made *many* more phone calls to
TechWorks, all to no avail (I wouldn't give-up because I was so disgusted.)
Sales/support people, supervisors, there was nothing I could do to pursuade them
to "make it right."
I finally (in total disgust) wrote a letter to my credit card company, asking
them to investigate the problem.   Three weeks later, the credit miraculously
appeared on my statement.  I have not (in recent memory) been so disgusted with
the service that I received from a company.  In all fairness, they had no way of
knowing that was not trying to rip them off, but I went to *such* great lengths
to prove to them that this really happened.  Oh well, c'est la vie.  I will never
buy another product from them again.

I've had the board for over a year, and it does work with Diskdoubler,
but not with Autodoubler, due to a licensing problem with Stac Technologies,
the owners of the board's compression technology. (I'm writing this
from memory; I've lost the reference. Please correct me if I'm wrong.)
Using the board, I've had problems with file icons being lost, but it's
hard to say whether it's the board's fault or something else; however,
if I decompress the troubled file and recompress it without the board,
the icon usually reappears. Because of the above mentioned licensing
problem, the freeware expansion utility DD Expand will not decompress
a board-compressed file unless you have the board installed.
Since Stac has its own product now, it seems unlikely that the holes
in Autodoubler/Diskdoubler related to the board will be fixed.
Which is sad, and makes me very reluctant to buy Stac's product since
they're being so stinky. (But hey, that's competition.)

Is that the low-end configuration?  If it is, it has the 68LC040 (no FPU), as
opposed to all the other configurations with a 68RC040 (has an FPU).  Be sure
you know what you are getting before you buy!!!  The 68RC040 is around
$350-$400 right now, if you intend to upgrade it from a 68LC040.

I'm having a real tough time finding out the proper adapters to use a VGA
monitor (an IBM 8513 sold w/ many PS/2's to be exact) on the Mac LC III.
All of the vendors I have called say that the internal video will not work
on a true VGA monitor but will work on a IBM Compatible multisync like the
sony's or the NEC monitors.  I thought the VGA capability of LCIII was very
attractive because it allowed you to use inexpensive VGA monitors.  Am I
confused or are these vendors just not up to speed?  Has anyone used an
LCIII with a non multisync VGA monitor and if so where did you get your
adapter (please be specific w/ vendor and cat #)?  I would prefer to get a
apple monitor for these LCIII's (it's unseemly to see the finder inside an
IBM bezel) but the more money we save on monitors the more LCIII's we can
afford and the more PS/2's we can get rid of!

Tell that to the Japanese, their local market is neatly protected by

the only current way to break into it, is to do it with a Japanese

It is very possible to connect another internal hard disk in any
macintosh if you can find the space to put it. I have a IIsi that came
with a Quantum 80 meg drive. When I ran into space problems, I slapped in
another 40 meg quantum that I had sitting on a shelf. Here is what I did.
First off, I was concerned about space. Since both drives are Quantum
quarter height drives, I finally decided that the logical place for them
was stacked one upon the other. Fine, they fit snugly. (I have not had a
problem with heat yet, and these drives have been running together for
over two months.
The next problem was connecting the drive. If you have a spare internal
hard disk power cable as I did, then half of your troubles are over. just
splice in the extra cable so that you get one square motherboard
connector and two hard disk power connectors. If you don't have a spare
cable, you will have to buy the wires and connectors which can be found
in any good electronics store for about $10. I would suggest properly
soldering/heatshrinking the connections to reduce the possibility of
shorts or bad connections.
Next, you need a ribbon cable connection. Again, I had a spare hard disk
ribbon cable, and I wanted to be careful in case this didn't word so what
I did was purchase a crimp on 50 pin cable connector that gave me another
male connector in the middle of my spare cable. The part cost $10 again,
and is easily attached with any good wood vice. The theory behind using a
crimp on connector is that if this doesn't work, my original cable is not
damaged, and I can go back to the original setup.
Having done all that, I couldn't be bothered to check the dev notes for
power consumption so I plugged it in and it works like a charm to this
day.
In a mac II, everything should work the same. Be careful with the ID's of
the drive, and ensure that the terminating resistors on both drives are
intact. I did not try this without the terminating resistors but it
seemed logical that if I am splitting the SCSI chain, that the signal
should be terminated at all the ends.
Let me know if you have any more questions.

there seems to be an extra connector socket on the back that I can't

Second, it would be nice to get a hardware manual for the drive. There are
a lot of jumpers on it that we don't know what they are for.
Third, I have got the drive to format. It took a while to get things to
work and most of it is fine for now. The formating initialy was
troublesome but seems to be ok. The main problem is if you do a reset on
the MacPlus the drive disappears. If I shut the mac off and then back on

I don't know how to say it best but you are gaurenteed that the
price of the C650 is going to drop this year.  This week's MacWeek
reports that Apple is probably planning a drop in August.  My guess
is that it may come sooner if Apple decides to  change the price
structure upon release of the multimedia units this summer.
Your price looks pretty good at about $50 more then I payed for
mine last month.  I would have rather waited for one of the new
machines this sommer (like the Cyclone) but the resale value of my
IIci would have not been squat by then.  Thus, financing forced me
to purchase now.  I'm happy with the machine and won't feel
betrayed at all when Apple cuts the price to less then $1000 next
week (heh).
Bottome line:  If the C650 does what you want, buy it.  If you wait
until the Cylcones come out for a price break then you might as
well wait for the PowerPCs to come out for another price break and
then the units which follow them.  You may save some money but
you've lost a lot of time when you could have been using the
computer.  Face it, Apple's prices are going to be in a continuous
state of flux.  At least they aren't going to try raising them
again (grin).

Subject: Axion Serial port switcher: Good or bad?
Organization: Drexel University
Lines: 26
Hi!
I'm looking into buying a serial port switcher, because while my Mac has
two serial ports, I have AppleTalk, a modem, a printer, MIDI, and a sound
digitizer.  (2 != 5, unfortunately.)
Specifically, I'm looking at the Axion electronic switcher, because it
seems to be fairly cheap.  (About $128 at MacZone.)
Does anyone know anything about it?  I've heard that with most of these
things you can still only use 2 serial ports at a time, it just prevents you
from physically swapping cables.  Although I've also heard that programs
that use the Comm Toolbox may be able to use as many serial ports as they
want; does anyone know if this is true with the Axion switchbox?
Finally, if the Axion stinks, or if you're using something else that you
think is good, I'd be interested in hearing about other products.  I would
like to spend under $140, if possible.
Please reply through mail; I'm not a regular reader of this newsgroup.
If there's interest, I can post a summary of replies.
Thanks a lot!

I have the a CD-Technology drive with the Toshiba mechanism, and it is
supposedly the fast and best now.  It has an access of 200ms and a data
transfer rate 300Kb/sec.  It is multisession photo-cd compatible.  It is
available from educorp for $599, the CD-Technology one, and comes with two
mail in coupons for two free CDs.  I'm not sure if the cd's are good, since
I've only had the drive a little less than a month and had the cd's shipped
to my home address in california instead of here in maryland.  The
CD-technology drive has a separate power supply separated from the drive,
which supposedly gives it a longer life, and keeps it cleaner with no fan to
attract dust.  A Toshiba brand drive is also available, but I think the
CD-Technology is better, since you get the same mechanism, and at a slightly
lower price with two free CDs.
The Apple 300/330i Drive, Sony Mechanism, is around a 300ms access time I
think, and a data transfer rate of 300Kb/sec.  I know it is the slowest of the
three mentioned here.  It is not widely available, except through the apple
catalog, which is bad at a price of only $599.  It is also multi-session photo
cd compatible. I think the external model comes with 7 free cds, some of
which are pretty good.
The NEC drive has been out the longest.  it has an access time of 280ms and
a data transfer rate of 300Kb/sec.  it is available from many vendors around
$600 dollars, including Educorp.  It wasn't multi-sesssion photo-cd compatible
before, but I hear that the current version that is shipping is.  Owners of
the older drives can get an upgrade.  It does not come with any free cd's
unless you buy it in a bundle.
Of the three CD-Rom drives above, i think the best choices would be the
Apple drive and the CD-technology(toshiba) drive.  The apple drive for it's
compatibility with apple products and the cd-technology(toshiba) for it's
speed and performance.
BTW, the models of the drives are:
Apple: AppleCD 300 or AppleCD 300i (internal)
CD-Technology:  CD-T3401 (the Toshiba brand name model I'm not sure, but it
is also something like with 3401)
NEC:  CDR-74
I'm very happy with my drive.  And have had no compatibility problems
whatsoever.  If I am wrong about any of the above, do correct me, but I am
pretty sure of myself, even when I think I'm not.
Also, some of you out there might notice that I have the same last name as
the president of CD-Technology which happens to be in southern california,
my hometown.  However, I AM NOT a relative nor do I know the guy.  Liu is
just a common chinese name, especially in southern california, with the
enormous chinese community.  Besides, one of my doctors in california has
three Steve Liu's as patients and another Steve Liu comes to my school and
lives in the next dorm.  This is to show that Liu is very common.

Subject: Cannot move data fast enough!?
Summary: disk -> buffer -> network card
Keywords: NuBus, SCSI, disk, throughput
Organization: Gokuraku Videos
Lines: 43
I want to achieve an overall throughput rate of around 5 megabytes / sec
for very large data transfers.  (Around 5 MB.)
I have a Quadra 950.
I have a NuBus network card that can pump data in to mac memory at 8.5 MB/s.
(using block-mode transfers)
I have a high-speed disk array (no asynchronous PB calls) that can
achieve 6.8 MB/s.
Let's say all transfers go from disk to buffer to network card.
It is not enough to first transfer all the data from the disk to buffer,
then transfer all the data from the buffer to card.  (6.8 MB/s then 8.5 MB/s
result in an overall 3.8 MB/s.  Too slow!)
So I tried the following scheme: For an n-megabyte transfer,
Step 1:                                Load the 1st MB from disk to buffer.
Step 2: Asynch send 1st MB out card,   Load the 2nd MB from disk to buffer.
Step 3: Asynch send 2nd MB out card,   Load the 3rd MB from disk to buffer.
...
Step n: Asynch send the n-1 MB out card, Load the nth MB from disk to buffer.
Step n+1: Send the nth MB out card.
Even though the code apparently does execute the card transfer asynchronously,
and the card does not use the Mac cpu at all,  (It is using the buffer, tho')
each of the steps 2 through n take as long as if the two transfers were
executed one after another.  So there is no improvement in the rate.
Why?
Is the mac RAM dual-port?  (So the NuBus card and the disk driver can both
access data at the same time.)
Is the problem that the two devices, card and disk driver, both have to use
the same bus to mac RAM?
Is there anything I can do?

Well folks, after some thought the answer struck me flat in the face:
"Why would Apple release a Duo Dock with a processor of its own?"
Here's why- People have hounded Apple for a notebook with a 68040 processor
in it. Apple can't deliver that right now because the 040 saps too much
power, radiates far too much heat, and is too large for a notebook. How
does one get around that without designing a new chipset? Use existing
PowerBook technology to your best advantage. The Duo Dock gives Apple a
unique ability to give users that 040 power in a "Semi-Portable" fashion.
By plunking the 040 into the Dock, you've got "quadra" power at your desk.
On the road, that 33mhz 68030 should be able to handle most of your needs.
Okay, not the BEST solution, but its an answer to a no-win situation. :-)
So, does this mean one will be able to use the PowerBook's processor in
parallel to the dock's processor? Okay, we're getting REALLY hypothetical
now...

By rotating the plate around the mouse ball counter-clockwise you can open

it opens quite easily once you see what has to be done.

It would also be great for another reason - when not docked, it could serve
as an ARA server to the large internal HD, your corporate email, etc.  In
a pinch, you would also have two machines, instead of 1.5.
If they could couple that thought with RocketShare, and let you use both the
'030 on the PB and the '040 on the dock, it would be a mighty powerful dock.

I also use Retrospect, but I noticed that Central Point Software's
"MacTools Backup" also supports the Apple tape drive under 7.x.
The Apple tape drive is quite slow, so the advantages of Retrospect
relative to the simpler MacTools Backup are less significant than
might be the case for someone backing up a large server to a DAT drive.
Used Apple tape drives are going for ~$100, so it might make less
economic sense to pay an extra ~$140 for Retrospect when MacTools
is cheaper and includes other worthwhile utilities.
Retrospect is nice, though, and I'm probably going to upgrade to 2.0.

Apples HDSC will only format a hard drive that Apple sold.  You need to use

The Toshiba has a 200ms access time, the NEC has a 280ms access
time, right around the Sony/Apple. Access time is, of course,
somewhat important, but not as vital in the case of CDs as data
transfer rate.
All the drives are double-speed drives with maximum data transfer
rates of 300K/second. Any is a good choice. Apple's is very cheap
when included with new Macs and I agree with Christian's comment
about drivers.
Plus, Apple's is bootable on the Centris and Quadra 800. A very nice
feature if you need to install System software. I don't know if the
NEC or Toshiba are bootable on those machines.

I think the original poster meant opening the mouse, not just
releasing the ball and getting to the rollers. I found that on the
original ADB mouse, sometimes unscrewing the two halves allowed for
easier cleaning.
If the original poster has his answer, I'll ask: How do you open the
new ergonomic mouse? By open, I mean split the two halves to get at
the guts. It isn't obvious to me based on the 5 minute look I spent
with one at the office yesterday as there are no visible screw
heads.

Sounds about right.
If there is high demand for a product there is little incentive to
aggresively cut prices.  Once the demand fall off a bit, then is the
time to start getting aggressive with pricing.  Waiting too long can
really hurt your business though :-)
The PowerBooks have sold very well up to now, if they are slowing
down Apple needs to come out with some lower priced versions (the
only reason I own a PowerBook is that I could spring for a $900 PB100,
the rest of the lineup is way to pricey for me).  I'd bet they'll
be coming out with more power versions too.

Organization: fnal

NNTP-Posting-Host: phurh.fnal.gov
Here's a question that may be simple enough to answer, but has stumped
myself and a few others:
What does an external RAM cache card do for you if you already have a large
cache set (through control panel) in your SIMMs?
EX:  I have a Mac IIci with 20 meg RAM, an external video card (so I don't
rob my SIMM's), and the default Apple cache card (I believe this is 32K?).
Say I have my cache set at 2 MEG, what good does a measly 32K do me on the
cache card?  Could it actually slow things down by dividing the cache
between the card and the SIMM's?  Or does it still speed things up by
providing a 'secondary staging' area for data normally passed directly into
the SIMM RAM cache?
I'm confused because it seems like cache cards are so low in memory to
really do any good compared to what you can set yourself.  Yet, Daystar
FastCache has numbers which show around a 30% performance boost on some
operations.  Are the chips on the cache card simply faster than most SIMM
accesses?
Please help, I'm trying to find the optimum memory settings for the IIci
system described in the EX above.

Hello all.
I am thinking about buying an external monitor for my SE/30 and was
wondering if anyone out in netland has any advice for me.
I am mostly thinking about a 14" color monitor and an 8 bit card that
can switch between 640*480 and something higher (like 800*600).  I read an
old report on a card from Lapis that could do this, but could not use the
external monitor as the main screen (with menubar) which to me is a major draw-
back.  Has this perhaps been fixed? Or can any other cards do this (like the
Micron Xceed) ?
Also which monitor should I buy?  At the moment I am leaning towards
the Sony 1304, 1304s or 1320 (what exactly is the difference between these?)
but are there any other good cheap monitors I should know about?  Doesn't the
monitor have to be multisync to support cards that can switch resolutions?
Please send me e-mail and I'll summarize.
I would also greatly appreciate getting the e-mail addresses of any mail order
companys that sell monitors or cards.
Thanks in advance

I believe that in order to get at the innards of the new mouse,
you must remove the label on the bottom that says "Apple Desktop
Bus Mouse II"  There you should find two screws on either side.
I haven't tried it myself yet, but when I ran my fingernail
accross the label, these two divots appeared, and I can only assume
that these are the elusive screws in question.

Just thought I would mention that Sony no longer manufactures the CPD-

I'm assuming that you are referring to the 1304S, correct?  What kind of flaws
have been reported?  I've been using mine for about 6-7 months now, and I
haven't noticed any problems.  Might they develop later, or did I get lucky
and snag a good monitor?

I also returned PB memory last summer for credit, and the sales person warned
me not to use US mail.  I did (although I did insure the shipment), and
apparently Techworks got it.
My minor grip with techworks is that they have different price lists for
different people.  I ordered DUO memory, thinking I got their "best" price
because of my employeer.  I subsequently found out that Apple was offering
developers memory for less than techworks charged, called up to complain,
and was told I should have said I was an apple developer and they credited
my card for about 16% of the purchase price.   I like techworks quality
and installation instructions (and they include powerbook tools), but
for out-of-CA purchases (no sales tax) chip merchant seems to be a bit less.

Nope.  I'm pretty sure that this person knows how to take the ball out.
I think that what they want to do is take the mouse apart.  The old mouse
had four screws on the bottom that you could unscrew to do this,

Organization: Idaho State University, Pocatello

Hi, I have been getting a lot of requests for this information so I thought
I would post it for those interested parties. (Sorry for length).
To increase the MacIISi speed to 25MHz or 33MHz the clock must be changed
from 40MHz to 50MHz or 64MHz respectively.
This is done by going to a static-free work station or putting some
aluminum foil down to work on.
1. Open up the Si by lifting the tabs at the back of the case.
2. Remove the Hard Disk by disconnecting the power and SCSI cables,
spreading the tabs, and lifting the drive out.
3. Remove the flopy drive.
4. Remove the power supply by spreading the tab in front and lifting
the supply straight up and out.
5. Remove the fan by pressing the ears together at the back, bottom
side of the fan and lifting straight up and out.
6. Remove the Mother Board by spreading the tabs on the left and
right side of the board and sliding the board forward then
lifting the board out. (all connectors on the back of the
board must be removed first)
7. Desolder the 40MHz clock (the one closest to the memory modules).
This is not easy even for a skilled solderer.
8. Get an IC socket with the round pins and remove four of the pins
by pushing them up from the bottom with long nose pliers.
9. Put the four pins in the holes vacated by the clock and solder
them in.
10.Insert a 50MHz or 64MHz clock.
11.Put large power transistor heat sink's on the processor chip and
the other large chip just to the right of the processor and
figure some way to hold the heat sync's in place. I made a
simple clamp by putting a four inch screw up through the hole
in the board between the two chips. Mount the screw using
insulated washers. Screw a cross member down over the heat
sync's to hold them in place. Don't use too much pressure.
12. Put it all back together and go-for-it.
Disclaimer: this is only the procedure I used and is not authorized by anyone.
You are on your own for this procedure. I'm quite sure it will
void your warentee.

Does anyone work with the A/ROSE card?
We have the problem that after certain crashes the card disappears from the
system, and lets crash the Mac then.
Okay, we don't use the card quite like one should, because we simulate
errors in the 68000. Before every instruction some specified registers are
masked, eg. to simulate a stuck-at-1-error in certain bits.
Normally, the "crash instance" of A/ROSE notices a crash, sets a flag and
stops working. By reading the mentioned flag the Mac can notice a card
crash. That works fine for almost all crashes, but as said, sometimes the
card doesn't set the flag and disappears from the system.
The documentation of A/ROSE does not tell us anything about its behavior
when crashing, and so at the moment we are trying to understand by analyzing
the assembler code, and that's both frustrating and lengthy.
So, can anyone help?
Please only reply via email, as I don't read this group.

Flopticals have been available since the beginning of the year at $25
per floptical (= $1.20 per megabyte), and I have seen them advertised
in MacWEEK at $20 (< $1.00 per megabyte).  For someone on a tight

We have recently obtained a Centris 610 and it has developed an unusual
video problem.
Model:	610 with 8 MB/230 HD, 512K VRAM, no cards
Monitor:	Apple 16"
When the computer is set for 256 colors and certain operations are done,
particularly vertical scrolling through a window, horizontal white lines
appear on the monitor (which generally but not always spare open
windows).  These lines accummulate as the operation is continued.  If a
window is moved over the involved area of the screen and then moved away
the line disappear from that area of the screen.  This problem is not
observed if the monitor is configured for 16 colors or a 14 inch Apple
monitor with 256 colors is used.
I suspect a bad video RAM chip but cannot be certain.  The problem has
been apparent since day 1 but has gotten worse.
We were wondering if anyone has seen anything like this, and if so, how
to fix it.  Please also respond to azelenet@bigmac.mskcc.org.  Thank you
for your help.

There's this old SE here. It's got the older-style fans that remind
me of a house-ventilator. A cylindrical drum instead of the bladed rotor
I usually see. Anyway, the SE makes this loud buzzing noise due
to vibration somewheres. If I remove the screws and loosen the front
from the back, it quiets down. I can only assume that the fan housing
from this goofy thing is touching the back of the case and vibrating
against it.
Anyway, any suggestions for where to get replacement fans and how to
"stealth" this guy? Your experiences welcome.....

Bzzzzzzzzzzzzzzzzzzzzzzzt!! Sorry -- wrong. It would be an
extremely hot idea...at least with the current Alphas. The available
Alphas run up to 200 MHz. But they produce quite a bit of heat. In
fact so much that they need special mounting with extra large heat
sinks.
Also Apple looks pretty commited to the PowerPC route instead
of a deal with DEC.

I have a chance to buy a used PS/2 Appletalk card to create a network with
my home machines.  However, the guy who has the card tells me there's a
DB-9 or DB-15 (can't remember now) on the back of the card, rather than
the 8-pin (or 4-pin) mini-din that I expect.  This sounds more like a
Thicknet ethernet card.  Should there be a transciever on it, like on the
Quadras?  What would be a reasonable price to expect to pay for one of
these cards, keeping in mind that it's Micro-Channel Architecture, which
means take your best guess and double it.
Email replies would be appreciated, to here or to rrr@ideas.com

The 3FGx has a maximum horizontal scan rate of 49KHz, so driving it
at 60.24KHz to get 1024 x 768 on the Mac is WAY BEYOND the tolerance            The 4FG is spec'ed at 57KHz, so going 60.24KHz is only 5-6% above
the minimally guaranteed figure.
I too doubt if the Damark monitor would sync to a Mac at 1024 x 768.            Like most things, you get what you pay.  That's the deal.

This problem is usually a low +5 Vdc from the power supply, there is an
adjustment for this on the supply. If the voltage is still unstable or low
then the culprit is probably a bad rectifier at CR20.

Yes, but if you upgrade the VRAM in a 900 you get 24 bit color.  So
you really don't care.  My point is that out the box the 950 has
more video capability for the same size monitors.  The 900 can
do 24 bit with both 13" and 16", doesn't support 19", and
does 8 bit on 21" monitors.

Sorry, I assumed that the the various new machines with the internal

Complete Q700 are best obtained from your dealer or some recent
copy of MacWorld or MacUser.  My foggy memory suggests that the most relevant
comparison factors vis-a-vis a IIci are as follows:
25 MHz 68040
16 Mhz data path (don't recall this for sure, but it's slower
than Q 950 style machines for sure).
Ethertalk card on-board
Audio in/out
4 MB RAM on motherboard
4 SIMM slots
2 NuBus slots.
More flexible build-in video than the CI.  Uses VRAM.
In comparison, a IIci with an accelerator won't give you
audio or ethernet  or the same video options.
With a 68040 accelerator, CPU performance can be comparable but I
think it ends up costing more.

Sorry about the misinformation.  I made a bad assumption about
the new machines behaving like a Quadra 900, see previous
post.  About sampling the CD audio though, have you tried it?  I
found the aliasing to be really bad.  Like it needed a filter or something.
Much worse than I expected.  I installed the CD-300 in the
Quadra myself so maybe I missed something.  Everything else
works great though.

It would depend on the requirements of the poster's data, for some
purposes 1/256 resolution (with or without calibration curve).
Otherwise the other possibilities would be:
1) get a digital voltameter with serial output & connect to serial
port on mac, collect data with some communications program.
2) Buy an A/D chip from Analog devices, Burr-Brown, etc, connect to
a parallel to serial converter, use serial port for acquisition
(nah. too much soldering and trouble shooting :-)
3) Get a board from National Instruments, Data Translation, Omega,
etal.  The finest solution, but possibly the most costly.
To the original poster:  if the signal is too large, why not
use a voltage divider? Two resistors, cost very cheap...

Excuse me if this is a frequent question, I checked in
several FAQs but couldn't really find anything.
I have a IIsi with the standard 5 meg memory and I want
(need) to add additional memory.  But I'm on a budget.
I really don't need more than 10 meg max, so what is
the best (performance wise) and most economical way
to do this?  Someone told me that I should only use
SIMMs of the same amount of memory, that is 4 1 meg,
4 2 meg, etc.  What if I just wanted to buy just 1 4 meg
and use the rest of what I already have?  The manual
hasn't been very helpful with this.
Thanks.

Hi There,
I am trying to find out a reliable Power Center, it is basically
a surge protector that sits below the monitor and has individual control

The ones that I could locate in Microcenter catalogue were:
Tripp Lite's Isobar Command COnsole ($79)
Proxima Power Director (89.95)
Kensington Masterpiece Plus (109.95)
Has anyone used one of these? Could you please send me your feedback

I would be very wary of retail outlets selling as cheap as educational prices!
I went for a retailer, actually mail order (CDA computers), because its price
was better thant the campus computer store. I found out why later on when I
tried to get a repair done at an Apple registered repair center - the CPU was a
resale. The serial number had been removed and replaced with a non-standard
number (probably from CDA computers). Consequently, the Apple repair man could
not do ANY warrenty repairs. So I ended up with just a 90day warrenty from CDA
over the Apple 12month warrenty. Boy, was I pi**ed! Moral of the story, CAVEAT
EMPTOR.
However, if you go with a reliable, trustworthy mail order firm (if they exist
- maybe someone could enlighten us with their experiences), you will probably
get a better price than your local educational outlet simply because mail order
out of state does not REQUIRE sales tax yet. Though for how much longer remains
to be seen. The addition in sales tax on a CPU purchase will probably wipe out
an educational discount. Again CAVEAT EMPTOR, some mail order companies DO
include sales tax on purchases even if they are out of state, so check!

In certain Apple 13" RGB monitors there has been a problem with
the HIGH VOLTAGE CAPASITOR. Apple knows about this problem and is
replacing the cap at no cost if it falls into the bad batch that
they got from their supplier. Your local repair shop should know about

of course it was in Dale's post, just not in the words that MacUser
used.  ROM accelerated video just means that some quickdraw commands

A professor of mine once said "The difference between a Computer Engineer and
a Computer Scientist is about $5000" meaning the Engineer makes $5000 more than
the CS.
Seriously though the main difference is that most CS people write programs that
people will use, i.e. database, graphics, word processors, etc., while an
engineer writes for machines or control systems, i.e. the "computer" in your
car, a flight control system, computer controled devices, etc. In other words
CS writes SOFTWARE while CSE writes FIRMWARE.
These are generalizations but for the most part that is what the difference is.
P.S. The $5000 is not just a joke

The service notice on the 13" hi-res monitors expired 3/23/93 after this
date Apple will NOT reimburse service providers for the fix (replacement
of the hi-voltage capacitor). All you folks that have been putting up with
intermittant shutdowns without getting it to your service provider missed

Yea, thanks to lots of good information in this newsgroup, I was prepared
for lots of details (even shipping time ... got my C610 8/230/CD in 5 weeks).
I guess my biggest disappointment is the lack of detail in the written
specs and documentation.  The case load spec is an example -- the setup
section says Apple 14" and 16" monitors can go on top, but 21" and other
big ones can't.  Why couldn't they publish a maximum load?
Now if I can figure out if there's any hope using the "partition" button

I'd appreciate it greatly if someone could E-mail me the following:
(if you only know one, that's fine)
1) Specs for the 68040 (esp. how it compares to the Pentium)
2) Specs for the 68060 with estimated cost, release date, etc...
I'm interested in speeds, systems it can run (Windows NT, RISC, or whatever),
costs, bus info, register info.  All the technical info.
I am hoping that the 68040 can win yet another battle against the intel people.
:)  Thanks for any info you can give.
Thanks.

Does anyone have details on this?   What sort of FP errors is

(My Q900 is having some strange problems with an FP intensive

Terry, hi.  I recently bought an LCIII and a Datadesk 101E.  I can't
remember trying to rebuild the desktop with it, however it did give me
a strange problem.  When I held down shift during startup to disable
all extensions, nothing happened. I tried it with another keyboard, using
the same adb connector cable- and it worked with the other keyboard.
The shift key on the Datadesk keyboard worked well otherwise. I checked
the dipswitches and they are fine.  Try disabling your extensions and tell
me if it works.
I am annoyed with Datadesk.  I sent them the keyboard in the mail for
inspection/repair/replacement.  The technician on the phone said they
have a 10-14 day turn around time- meaning you should receive the
inspected/repaired keyboard in that time.  Well, they have had the
keyboard for over 3 weeks and I still have gotten very little info
from them about it. It's annoying because it cost me $12 to send them
the keyboard (they do not refund the money) and their costumer service
lines are toll calls. Tell me if you have a similar experience.

Apple does not authorise sales through Mail Order.  As a result mail order
companies have to obtain their machines by the grey market.
This market is supplied with machines from authorised resellers who have
more machines than they can sell.  They come into this state of affairs
by overordering either accidentally or deliberatly to get a better
wholsale price from Apple.  In either case they often obscure the serial
nunber to protect their identity.  As a result the warranty is void.
You may save on sales tax but you have to pay for shipping.
I should also point out that mail order companies cannot get lower prices
thatn the high volume authorised dealers unless they buy below dealer
cost.  As a result the only way they can sell cheaper is by cutting costs
and trimming margins.  Unfortunatly they dont seem to be doing too well.
The lowest prices I have been quoted mailorder do not beat the lowest
prices available from authorised local dealers.
They are even further away from educational prices.

I just recently purchased the GCC BLP Elite and I really like it.  My
needs
are much the same as what you describe.  In addition, I wanted to get one
that
I could access via AppleTalk, so that eliminated the new line of
inexpensive
printers from Apple.  The print quality is good to excellent based on
what
font you're using and what paper you use.  I'm still experimenting with
different papers, but a medium grade laser printer paper seems to work
fine.
Printing envelopes, transpariencies, letter head, or other single feed
jobs is
very easy.  There is an adjustable, automatic centering, guide on top of
the
sheet feeder which aligns the paper properly (and doesn't feed a sheet
from
the sheet feeder, as some do).
(I have no affiliation with GCC, just a satisfied customer.)

An added advantate of waiting for the DayStar for the SE/30 is that,
just as with the '030 power cache, the '040 accelerator will plug into
the CPU socket, leaving the PDS slot free for a video card or ethernet
card.  With DayStar's upgrade path, it's a no lose situation.

No, he's not missing anything.  You're right that some models of the 650 ship in

I've just completed a successful upgrade of a an SI to 27.5 mhz. I'm waiting
on delivery of a 62 mhz clock for a final speed trial. Definitely needed the
heatsink. The CPU was quite hot to the touch at higher speeds until I glued
on a 90 cent Radio Shack sink.
I made a call for reports of failures last week. No reports have arrived
here. Locally, in Seattle there is a reported CPU damage due to the user
slipping with the iron and putting a gash into the board -- not exactly
a problem due to the CPU running too fast.
I think it would be nice to have a poll to report top speeds and system
configurations including PDS and Nubus cards which were used. I'd be happy

It clearly depends on the type of questions you are asking but in many
cases it will do fine. The critical information from the neuron is in
the firing frequency (maximum about 100 action potentials per
seconds), and not in the amplitude of the signal or in details of the
signal shape. So the resolution of about 0.4 % you get with an 8 bit
convertor is more then sufficient.
AC coupling does not have to be a problem either, since in many cases
you are not interested in the DC level. My pre amplifier is AC coupled
also. The critical point is the lowest frequency that will pass. If
the cutoff point is to high, the action potentials will be slightly
distorted. But even that normally does not matter since it is the
occurrence of the spike that is important.
However, I do want to know what exactly I can expect before I start
battling with the toolbox to get it going. As yet I have no clue were
to start looking for the technical specifications.

Ben,
Since you're obviously adept enough to understand how the trackball works,
the only thing short of repairing it that I can think of is a thorough
cleaning of all the parts, and then checking for the proper placement of
the little blue rollers. Since they aren't fixed in position on their
stainless steel pins, you might try sliding them into a slightly different
position. On my PowerBook 100, I can slide them almost completely out of
contact with the trackball. In fact, one of the notes from sumex on fixing
the trackball advocates sliding the roller so that its _edge_ contacts the
ball, not the center cylindrical area.
I've done this with my PB100, and it does seem to improve the feel, but
needs to be adjusted from time to time. I just popped open one of our
office's PB170s, and while there isn't as much latitude for movement, one
could still adjust the roller slightly. If your PB140 is the same it might
help.
I would suspect the most likely culprit to be a slippery blue roller. If
you can take it out, clean it with a mild soapy solution, or isopropyl
alcohol. Also, be sure the ball is grease-free.
If you drop the ball in minus the retaining ring, roll the ball and see
if it is actually causing the axle to spin.
If all this still doesn't solve it, then maybe a new one is in order. :-(
It could be an electrical connection, in which case replacement would be
necessary. But my experience with both mice and trackballs has been that
dirt has been the normal problem, not an electrical malfunction.
Hope this helps,
Murray

I have the same problem and was about to post this....
Hello duo owners (and Apple technical people :-)
I have a new duo 230 which appears to have a problem waking up from
sleep when running on battery power. When woken (usually for the second
time) after sleeping, the wake fails and the screen appears with a
corrupted image of broken horizontal lines and control can only be
recovered with control-command-poweron or the reset key at the back of
the machine. The problem occurs even when the system is stock standard
(no extensions, no virtual memory, a fully charged new battery, system 7.1
etc). I have not had the problem when the machine is plugged in to AC.
I've checked that the battery is properly seated (it appears to be fine).
What's going on here ? Anyone else had this problem ? Is it software or
hardware ?
If you have a duo 230 and a bit of time, try repeatedly sleeping and
waking the machine on battery power and let me know if you see the same
behaviour (and let Apple know too !).
Many thanks to anyone who can clear this one up for me.
Bruce

Finally got my computer fixed and I'd like to sum up.
About hard drive companies: the original 160 meg drive that was bad (bad
sector or something) was an IBM.  The new one is a Quantum.  Is the LCIII
supposed to be shipped with IBMs?  Is there a quality difference?
Apparently! :)
Second, about hard drive position.  I've put the LCIII on its side and
the new 160 HD has had no problems at all.  I've even switched back and
forth between horizontal and vertical and there are no problems.  As far
as I'm concerned I don't believe HD position is important for drives up
to 160 meg, in any computer.  Don't know about CD-ROM, though.

Noooooooo!  I've been servicing Macs for years too, and I've had to
repair a number of motherboards that had been damaged this way.  It's
rare, but it does happen.
Mind you, this doesn't mean you shouldn't do it.  The parts that can
blow (the ADB power fuse and RF filter) aren't too expensive, so IF you
have a someone around who can do component-level repair, it may be worth
the risk (especially if you're around Seattle, 'cause you might get to
pay *me* to fix it :-))..  On the other hand, if your only repair option
is the Apple-standard logic board swap (major $$$$), you should probably
play it safe.

OTOH, some of us get lucky-- I've unplugged and replugged SCSI and ADB

to be affected somewhat by opening windows and pulling down menus.
It looks to a semi-technical person like there is a loose connection

>    The DECstation 5000 Models 200 and 240 come with ThinWire only
>(can't say for certain about the Models 125 and 133), so your best bet
That's not true. Only the DECstation 5000/200 comes with a Thinwire
(BNC, coaxial) Ethernet connector. The 5000/25, 5000/133 and 5000/240
all have a single 15-pin AUI Ethernet connector only. I distinctly
remembered this because when got the 5000/200 first and I thought all
of them are going to be Thinwire. I eventually had to go back and ordered
DESTAs (DEC's oversized version of an AUI-to-BNC adapter that MUST be used
with a transciever cable) for the rest of the stations.
My advise to the very original poster (Beverly?) is:
(1) If all you want is to create a LAN with two workstations and won't add
machines to it EVER, go for Thinwire regardless of the media type. Going
for UTP (unshielded twisted pair) wiring requires a concentrator which
means extra money and I believe these units come with at least 6 ports.
As for Thicknet, it's a nightmare and cabling is expensive. Avoid it
unless you have no choice (e.g. the two machines are two floors parts).
(2) On the Mac side, you will need:
- one Thinwire media adapter (from Apple or third-party).
- MacX (make sure you get version 1.2; 1.1.7 won't run on System 7.1).
- MacTCP (which comes with MacX; if you get MacX v1.2, you should be
getting MacTCP v1.1.1 with it. Don't use earlier versions on a Centris).
- you may or may not need a 25ohm terminator depending on the
Thinwire media adapter. So just ask the sales if the adapter is
self-terminated or not.
- configure MacTCP to use "Ethernet".
(3) On the DECstation side, you will need:
- for a Model 200, you will only need a T-connector.
- for Models 25, 125, 133, 240, you will need an AUI-to-BNC adapter.
Get one that can be plugged in directly to the AUI port of the
DECstation. This way you save the cost of a transciever cable
(a 15-pin AUI male to a 15-pin AUI female cable).
- get a 25ohm terminator.
Your two-machine network will look like this:

For a good display, you *must* get an active matrix panel and a *very*
bright overhead projector designed to be used with an LCD panel (i.e.
stage must not get too hot). I tried out a Proxima Ovation unit and liked
it, but I needed a brighter projector (I used it with a 3M 920). It is
also too expensive for what you get, IMHO. Prices of active matrix panels
are rumoured to drop substantially sometime this year (something to do
with tarrifs being lifted I think).
In Canadian dollars, the Proxima Ovation models ranged in price from about
$5000 to $7000 and a good overhead projector about $1000 to $1500. For
that kind of money, you can get a brighter image from a three beam
projector, but sacrifice portability.
Oh yes, proper room lighting is extremely important, especially if you
want your audience to have enough light to read handouts and not have that
light wash out your display at the front of the room. Tricky to get right.

I have an old Mac Plus. A couple of years ago I bought a shiney new lc.
It came with apple's new keyboard (with abd ports). i replaced it with
a mac-pro-plus extended keyboard (which i thoroughly enjoy, thank you
very much).
well, i have this extra keyboard which i would like to use on the plus
but there's a little problem. the plus uses an rj-11 jack for keyboard
input and the new keyboards don't. i got an extra adb cable from my
local apple dealer (they're such nice people), but they couldn't tell
me the order of the wires.
there are four wires in the adb cables: black, white, red, tan. I know
one's a ground, one gets the serial signal, one supplies 5 volts, and
i forgot what the fourth one does. anyway, if you hook them up wrong
you'll fry a board and i <really> don't want to do <that>.
if any brave souls out there have done this before, please e-mail your
experience directly to me. i would greatly appreciate it especially
since apple's original keyboard is not . . . ergonomically correct.
btw, i did take apart my new keyboard to see if i could find the
correlation between the wires for the rj-11 jack and the adb since it
has both, but no such luck (the connections are soldered inside of
little boxes). Oh, well . . .

I know one solution is NOT to put the machine to sleep, but does anyone

The problem is that the pins in the ADB connector
are close to each other, and if you happen to bend the
cable a little while inserting it, you short the ADB
port. If you take it to an Apple Repair Centre, that
means a new motherboard (though a component replace IS
physically possible)
Same goes for serial ports (LocalTalk as well)

Even the 68000 can fetch two bytes at a time.
The new instruction in the 68040 is MOVE16 which fetches 16 bytes

I haven't seen much info about how to add an extra internal disk to a
mac. We would like to try it, and I wonder if someone had some good
advice.
We have a Mac IIcx with the original internal Quantum 40MB hard disk,
and an unusable floppy drive. We also have a new spare Connor 40MB
disk which we would like to use. The idea is to replace the broken
floppy drive with the new hard disk, but there seems to be some
problems:
The internal SCSI cable and power cable inside the cx has only
connectors for one single hard disk drive.
If I made a ribbon cable and a power cable with three connectors each
(1 for motherboard, 1 for each of the 2 disks), would it work?
Is the IIcx able to supply the extra power to the extra disk?
What about terminators? I suppose that i should remove the resistor
packs from the disk that is closest to the motherboard, but leave them
installed in the other disk.
The SCSI ID jumpers should also be changed so that the new disk gets
ID #1. The old one should have ID #0.
It is no problem for us to remove the floppy drive, as we have an
external floppy that we can use if it won't boot of the hard disk.
Thank you!

I own a Mac IIsi and am considering upgrades (cards, hard drive, etc).
Can you tell me what the power limitations are for 1) the PDS slot
and 2) the hard drive power feed. Secondly, Can you tell me if there
is a separate limit for each, or if instead, there is a single limit
for both combined?

This doesn't sound right to me.  Don't Quadras use the 53C96?  If so, the
Mac has nothing to do with the SCSI timing.  That's all handled by the
chip.  About the only the timing could be wrong is if Apple programs the
clock registers wrong on the 96.  That, however, should only really hurt
synchronous transfer, which is not used by the Mac SCSI Manager.
Furthermore, disabling blind writes should be meaningless on a Quadra.
On Macs that used the 5380, which is a much lower level SCSI chip, the
Mac was responsible for the handshake of each byte transferred.  Blind
mode affected how the Mac handled that handshake.  On the 5396, the
handshake is entirely handled by the chip.

Subject: Disappearing hard drive in LC?
Organization: CONCERT-CONNECT -- Public Access UNIX
Lines: 31
The internal HD in my LC disappeared for a day last week, and I'd like to
hear any (reasonable) theories folks can suggest for what happened.
It is an LC, with 10MB of RAM and an 80MB internal drive, running system
7.1, with a few SCSI devices in a (so far as I know) properly terminated
chain.
I had shut down the system for a day-- I was out of town and we sometimes
have thunderstorms this time of year-- and upon restarting got a blinking
question mark.  I booted from a floppy and saw that my external HD seemed
okay, but there was no sign of the internal.
I installed a system folder on the external and was, indeed, able to boot
from it.  I tried things like Disk First Aid and Silverlining, to inquire
about the internal drive.  They either could not find it or got errors in
trying to talk to it. (Silverlining claimed it was a Connor drive, but it
is a Quantum... )
Well, I'd backed things up, so I was able to work.  But, at some point I
noticed that the internal had reappeared.  Now, Disk First Aid says that
all's well, etc.  Things seem to be fine.
But, what happened?  Was this a warning that something (the internal HD
or something else) is about to die?  I'm definitely nervous.
And, if this is a signal that the internal HD is sick, is it true that I
can only put up to a 127MB drive inside an LC?  Some folks have claimed
there's a limitation in the LC (other'n size or power) while others (and
that includes LaCie, over the phone) say anything that fits is okay.
Thanks for answers.

My Datadesk Mac 101E keyboard has similar problems. I have found that
holding down the RIGHT-HAND shift key at startup will work (disable

Similarly, I have trained myself to hold down the RIGHT-HAND pair of

I had the same question for my 55lb NEC 5FG monitor. The Apple guy said that
their 50lb 16" monitor is OK to put ontop of the Centris and had no coment
beyond that. I was going to just put the NEC on the box but then I got to
thinking - the monitor has a small tilt/swivel base so maybe the weight
would be more concentrated than with Apple's (I don't know the area of the
base of their tilt/swivel). Additionally, the CDROM drive is in the middle.
So I cut a piece of 3/8" thick wood to about 16.25" x 12", covered it in a
cream covered cloth, and used it as a buffer layer between the Centris's top
and the monitor!!

Ravi,
Its not a good idea to have a horizontally formatted hard disk in a
vertical position.  If the drive is formatted in a horizontal position, it can
not completely compensate for the gravitational pull in a vertical position.
I'm not saying that your hard disk will fail tomorrow or 6 months from now, but
why take that chance?  If you want more detailed info on the problem, please
mail me at:===> sunnyt@dna.bchs.uh.edu <===.

Sunny,
I asked this question a while ago while contemplating placing my 650 on
it's side.  I received a response from someone at Seagate (Sorry I
trashed the message) stating that most newer drives (Seagates at the
least) can very well compensate for gravity.  This means that a
horizontally formatted drive can be later placed vertically with no data
integrity problems.  The only way that newer drives cannot work is if you
have varying forces (shaking, bouncing, etc) so don't place the drive on
it's side on a rocking chair :).  What constitutes a 'newer' drive I
don't know, try calling your drive manufacturer.  I have a Quantum LP240S
internal, and since I got it a month ago, I am guessing it's 'newer'.

I currently use an HP DeskJet with Grappler LS ver 1.0,
and it works on System7.  Course, I only use the SWA Dutch
and SWA Swiss fonts that came with it, due to the 4x size
requirement to print to the HP. (ie: must have 40pnt definition
to print a 10pnt font)  When I upgraded,  I talked to Orange
Micro, and they state that ver 1.2 of Grappler LS definitely
works with System7.  However, the upgrade was US$40, so I
passed.
Hope this helps?

I doubt this is a Quadra-specific problem.  I had to get
rid of my "venerable" Bernoulli 20 last year (with enough
cartridges purchased at ~$90 each to make the whole thing
worth more than my whole computer ;).  The tech support guys
at Ocean Microsystems suggested that some third-party drivers
might fix the problem - in my case the cartridges wouldn't
format/mount/partition for A/UX.

The original Mac II had an Apple MMU chip installed which performs a subset
of the 68851's functions.  If you look underneath your front left floppy
bay you will find three chips, all approximately the same size.  One will
be the 68020, the next the 68881, and the third, approximately the same
size, will be the Apple chip.  It is easy to spot because it has a 'hump'
in the middle of it.
Example:
-----------
/           \
---------------             ---------------

That and the Apple logo should make it easy to find.

It should not matter for the hard drive or the Mac.  Well, as long as it

When I owned an SE, I replaced the fan with SE Silencer, available, I
believe, from MacWarehouse or MacConnection.  It comes with instruction for
installation and requires no soldering.  Worked like a charm.  I think the
manufacturer is Mobius.

Yes. That is exactly what it means. The LC family of Macs can only

Well, I also have an LC III.  Popping the top revealed:
One "socket" for an additional VRAM SIMM
One "socket" for a 72-pin RAM SIMM
One socket for a flat-pack FPU
A processor-direct slot (PDS) identical to the LC/LC II, but with
an additional set of connetions to one side (for the full 32-bit
data path that the LC/LC II lacked
That's it.  I guess a board with a PowerPC chip could be made that would fit
in the PDS, but that's the only place.

According to the (seen several times) postings from Dale Adams of Apple
Computer, both the 610 and the 650 require 80ns SIMMS - NOT 60 ns.  Only
the Centris 800 requires 60 ns SIMMs.

The Partition button in Apple's HD Setup lets you set up A/UX and other
types of partitions. It WON'T let you create more than one normal mac
volume. You need SilverLining or something similar to do that. It WILL,
however, allow you to take advantage of some possible unused space on your
hard disk, if you don't mind reformatting the whole thing.

Apple doesn't make such a card, though I suppose a third party could.  One
big problem is that there isn't room for a standard NuBus card inside the

The audio will simply select the CD audio when the microphone is removed.
I don't believe the button un-dims, since there's nothing to select.  I

I like it a lot. It is worth the additional expense. The only problem I
found is with MS Word (5.1a). If you have a table the is longer than
a page and the cells have a visible border, the last (bottom of page)
line on the first page will be missing. It makes no difference how
the table is formatted. The worst is that it doesn't show up in word's

Dynamic RAM is not based on flip-flops; there's basically a single
transistor and capacitor to store each bit!  Static RAM is based on
flip-flops, and is much more expensive and much less dense.  And
neither has any parts that "move", if electrons and thermal expansion
are ignored...

I have a new 25 MHz Motorola 68040 that I am willing to sell if I get

If I don't get a good enough offer, I will use it to replace my 68LC040.
Any takers?
Supposedly you can get one of these for $375.  However, at the moment the
demand is higher than the supply so I think $400 is a good round number.
I will pay shipping, of course.

Subject: updated keyboard question for the plus
Organization: Illinois State University
Lines: 44
I have an old Mac Plus. A couple of years ago I bought a shiney new lc.
It came with apple's new keyboard (with abd ports). i replaced it with
a mac-pro-plus extended keyboard (which i thoroughly enjoy, thank you
very much).
well, i have this extra keyboard which i would like to use on the plus
but there's a little problem. the plus uses an rj-11 jack for keyboard
input and the new keyboards don't. i got an extra adb cable from my
local apple dealer (they're such nice people), but they couldn't tell
me the order of the wires.
there are four wires in the adb cables: black, white, red, tan. I know
one's a ground, one gets the serial signal, one supplies 5 volts, and
i forgot what the fourth one does. anyway, if you hook them up wrong
you'll fry a board and i <really> don't want to do <that>.
if any brave souls out there have done this before, please e-mail your
experience directly to me. i would greatly appreciate it especially
since apple's original keyboard is not . . . ergonomically correct.
btw, i did take apart my new keyboard to see if i could find the
correlation between the wires for the rj-11 jack and the adb since it
has both, but no such luck (the connections are soldered inside of
little boxes). Oh, well . . .
one more thing: in case you are thinking that the ABD ports on the
newer models are different from the connection used on the plus---
you're right. however, you can use the telephone cable from the plus
and connect the mac-pro-plus keyboard via its own rj-11 jack. in
other words, this little engineering feat i wish to do *is* possible.
it's merely a matter of finding out the correct order.
omt, when i get this to work, i definitely will post the solution
so others can, too. thanx for the input.

I too have been watching the IIsi speedup reports and plan to upgrade in
the next few weeks.  The plan I have is to build a small board with a few
different crystals on it and to be able to switch between the different
speeds using a front pannel switch.  This way I can get the speed when
I want but I can also run at slower (stock) speeds it I experience any
compatability problems with any applications.  I don't expect to be able
to switch clock speeds with the system running, but if I can switch
without any lock-up problems, then I could switch to 33MHz when needed
and put it back to idle (20 MHz) when not needeed.  This would further
reduce the wear-and-tear on the CPU even with a heat sink.  Of course
I would not want to run the different clock signals through the switch
but use a chip or two on the board to select the frequency desired and
route it directly to the mother board.
I haven't started probing around inside my si yet.  Does anyone know the
voltage level to power the crystal oscilators?
Thanks.

I remember reading a thread a few days ago that mentioned removing an external

. . I was going to do that with my 610, but had a couple of questions.  My
PLI 80M syquest drive has a wire from the drive to an id# switch on the
outside of the case.  Where do I connect this switch??  Can the computer just
"tell" with internal drives?
I noticed that the drive will lay over part of the motherboard (I
didn't look closely, but I seem to recall it laying over the ram that's
soldered onto the motherboard?  Would that cause problems?
One last question!  Is there anywhere to order a faceplate cover?
the drive's front panel is smaller than the space left in the case (the
drive's panel is the same size as the spotsBM clone's cases).  Should I just
cut a hole in the plastic panel that is currently holding tmpty place?

Actually, an accelerator such as the Daystar 33 MHz 68040 is cheaper than
upgrading to a Q700 (25 MHz).  The accelerator costs about $1400 whereas
the upgrade costs $2131 (just quoted from my dealer).  However the Q700
upgrade gives you very fast built in video that supports monitors up to 21"
with 8 bit depth and up to 16" at 24 bit depth (with additional VRAM).  It
also has a SCSI port capable of a much faster throughput than the CI, which
makes a big difference if you have a fast hard drive.
If the improved video and SCSI features are important to you, you're
better off getting the Q700 upgrade, otherwise save some money and get an
accelerator.

Hi there,
I have a question regarding Quadras VRAM. I have tried to find info on this
but I could not get precise answers.
On one hand, we have a Quadra 950 with a 16" monitor, which is capable of
32-bit color. How much VRAM does it have?
On the other hand, we have a Quadra 800 with a 16" monitor, which is capable
of 8-bit color only, so it must have 512 Ko of VRAM.
I would like to take VRAM SIMMs for the 950 and put them in the 800 so that
both machines have 16-bit color capability.
Is it possible, and if yes, how many VRAM SIMMs should I take from the 950?
From the documentation I have, the Quadra 800 must get 1 Mo VRAM to have
16-bit color, is that correct?
Bonus question: where do VRAM SIMMs hide? From the 950 documentation, they
seem to be *behind* the power supply. Do I really have to take off the power
supply to access the VRAM SIMMs?
Thanks for your help!

2.  I heard that both Supra and Zoom use the same software.
Why are there so many complaints about the incompatibility problems
of Supra?  What kind of incompatibility is it?
3.  If I decided to buy the Teleport Gold, is there any
possibility to add a voice option in the near future?
4.  Has anyone heard of a possible voice option that Supra will offer
this coming summer?
5.  A person did mention a new AT&T modem.  Is it
getting good reviews from various Mac Magazines?
6.  If I want the best, fastest, most economically sound and
possible voice option, what fax modem should I buy?
Sorry for posting so many questions, but I think they're necessary.

Thanks so much in advance.

Keywords: SCSI, IIfx
Organization: NASA Ames Research Center
Lines: 46
I am having trouble with SCSI on a Mac IIfx. The machine is 3 years old
and I have been using the same hard drive (internal Maxtor LXT-200S) for
two and a half years. The disk recently crashed. I reformatted (Silverlining
5.42), but during the reformat I received random write errors during testing.
The error message reported was like:
Sector 0: Write error detected after testing good - sector not mapped out.
This occurred randomly all over the hard disk (which makes me suspect the
diagnostic's reference to Sector 0 ??? ). On the third reformat and after
reinstalling the SCSI read/write loops I was able to get through passes
2,3, and 4 with no errors. (Pass 1 for some reason reported a lot of errors,
but still mapped out no sectors.) I decided to go ahead and try to resinstall
System 7 and reload my data from a backup. This proceded normally; however,
I now have sub-optimal performance. Symptoms include:
o Frequent crashes
o Instances of extremely sluggish disk access requiring a reboot to
correct.
o Instances of not finding the disk on the SCSI chain on reboot.
- If I boot from Norton Utl. after this occurs, it cannot find the
disk either.
- The only thing that fixes this is recycling the power. It sometimes
requires several attempts.
QUESTIONS:
1) Has anyone had this type of problem before?
2) Is the problem with the fx motherboard (And its non-standard
SCSI implementation) or with my Maxtor Disk? Is there some
diagnostic software that would help me make this determination?
3) Is it a termination problem? I currently have external Syquest
and an external DataFrame XP60 on the chain. The XP60 is at the
end, and has internal termination; so I am not using the IIfx
terminator. I do have the SCSI filter installed on the internal
drive. I have run with this exact steup for 2 1/2 years with
one previous disk crash requiring a reformat (about a year ago).
I also have symptoms if I disconnect the external devices;
so I don't see how SCSI termination would now be an issue. Of
course who knows :-<
Help would be much appreciated.

Check out the National Instruments NB-DSP2300. This uses the Texas

I don't know about the Instrutech boards (though I plan to check them out),
but you need to be very careful checking the monotonicity and S/N ratio of
many of the "16 bit" boards out there. The NI boards are very clearly
specified in terms of monotonicity, S/N ratio, accuracy, etc; and the
NB-A2100 and NB-A2150 have all the dyynamic range and freedom from
distortion that you'd expect from a good, true 16 bit converter. This is
not true for the Spectral Innovations boards, for example.

Ah, but why?  Can some technically-hip Macslinger tell us what the

I've had my Duo 230 for a few weeks now and suffer from both
of the above problems. I reinstalled my system software twice
in an effort to combat the problems - thinking they were
system software problems. Initially reinstalling the system
seemed to help but not anymore. Occasionally when I try to
wake up the Duo I get a solid screen of horizontal lines on
the screen - it freezes.
I also get the high-pitched hiss occasionally - but only at
startup.
I've called the apple hotline (800 SOS-APPL) three times
already and finally they agreed something is astray after my
Duo's screen would go dim and the hard drive spun down by
itselft and put itself to sleep. This problem only occured
twice. Apple sent me a box to ship my Duo to be looked at in
New York but the problem now is intermittent and I can't
afford to be without my Duo at this time.
Anyone out there with these same problems?

I think the other replies sum up the fact that you can place a hard drive
on its side.  The point is this will only be sure to work on the 'new'
drives, namely 1/3 ht LPS drives that have a smaller platter and are also
more stable.
Why should I take the chance?  Because I've been running a Maxtor 1/3 ht
120 LPS on both its side and flat for about a year and I've had no
problems with it.  Period.
Like I always say, NEVER trust the manufacturer.

So, will it be possible to have a NuBus or PDS PowerPC upgrade, or will it
require a logic board swap? It would be interesting for Apple to come out with
a NuBus PowerPC that allowed use of the CPU's 680x0, like RocketShare. But I
guess that's getting a bit fantastic!
I was wondering, since MacWeek reported that developers were 'seeded' with
PowerPCs on a NuBus card.
Also, any word on machine arrivals or estimated speed? Last I heard, the
estimates were around 3-4 times the speed of a Quadra in native RISC mode. I
heard an Apple employee mumble something about the arrival of PowerPC machines
at a much earlier date that Q1 94, but I doubt it's true.
Finally, is the PowerPC developer's CD 'mini-course' available? I saw it
advertised in the developer's university calendar, and I'd like to know if it's
at all *interesting*.

------ X-posted to comp.sys.mac.hardware and misc.consumers -------
You've heard about Apple's great new customer "support" program.  Well,
think again.  Sometimes the only real support out there is what Apple
computer users can give to each other.  For another example, read on:
In the March 15th issue of _MacWeek_, Ric Ford described a two-year effort
by Liam Breck to document and bring to Apple's attention a problem with
certain defective mice.  At random, the switches on these mice "stick" in
the down position until clicked a second time, apparently regardless of the
machine they are used with or the system software involved. Most of the
reported problem mice were manufactured in Malaysia and have an FCC ID of
BCGA65431. You'll recognize this "sticky button" symptom immediately if you
have such a mouse: the problem is intermittent, but it's not subtle.
Liam Breck recently gave up trying to document this problem, and instead
suggested that people contact Apple's Customer Assistance Center directly
(_MacWeek_ 4/5/93 p. 64). When I called Apple on March 23rd and described
my defective mouse, I was eventually given a case number (F83Y) and told
Apple would replace this mouse even though it is a few months out of
warranty.  After waiting for three weeks, I called back today wondering
where my new mouse was. This time, I was told that Apple had decided the
serial number on my mouse (MB13831FC25) is not within the (undisclosed)
range Apple is willing to replace, and there is nothing I can do about it.
Nothing, that is, unless enough people complain about this problem to make
it worth Apple's while to fix or replace the entire lot of defective mice.
Please, if you have one of these mice, I NEED YOUR HELP! Don't assume you
know what causes the problem (there are _lots_ of theories) and start
hacking around inside your hundred-dollar mouse. Instead, let Apple do it.
Please take five minutes to CALL APPLE RIGHT NOW at:
United States      1-800-776-2333
Canada             800-665-2775
UK and Europe      33-1-49-01-49-01
Australia          61-2-452-8000
Japan and Pacific  81-3-5411-8500
If the number isn't toll-free, call collect.  Describe the problem and ask
for a replacement mouse.  Even if they refuse, insist that they register
the details of your case, including your mouse's serial number.  Be firm.
Network managers and user-group leaders especially, please query your user
bases. Everyone ask your friends and colleagues.  Please don't send mail to
me or post yet another "sticky-button" report, CALL APPLE DIRECTLY!  If
enough victims take the trouble to report this well-known problem, Apple
will eventually be forced to respond.  If Apple continues to find it easy
to stone-wall on this issue, don't expect them to offer support when the
next, potentially more serious Mac defect is uncovered.

Hello all!
For few past days I've been fighting to get My NEC Multisync 3D
(predecessor of 3FG) to work properly with the internal video of Mac
IIvi.
With a VGA-adapter (as described in Dale Adams' posting about Quadra
video) it works, only some minor interferences occur, small enough not
to prevent any action on screen to be visible & clear.
But because the scanrates & stuff of 3D are well enough for emulating
Apple 13" RGB, I first made an adapter, then got one fron the local
distributor of NEC.
With both adapters I can get a picure, which looks excellent most of
the time or every now and then.
But with radical changes on screen (opening palettes, large windows
etc.) there are major interferences in sync. The picture either tilts
sideways or scrables up totally. Even when it is clear, there are some
"spiky" interferences on horizontal line alignment when accessing
pull-downs etc.
With the self-made adapter, almost identical to the VGA one, only
sense pins differ, it is sometimes impossible to even boot up with a
picture clear enough to shut down from menu...
With the adapter from NEC, everything is well most of the time, but
sometimes the picture tilts badly sideways or the sync is completely
lost. But not nearly as often as with the self-made one.
I know, with self made adapters there can always be interference, but
with the one provided by NEC... where's the source of this interference?
I'll give you the pinouts of the whole mess, and I hope that you can,
at least someone (please try =) figure out what could be the best pin
assignment for NEC 3D.
I am going to make a completely new cable with maximum shieldings and
isolations, as soon as someone figures out how the pins should be
arranged, especially syncs and groundings.
Yes, I have checked that the monitor is not defective, it works
perfectly well with all PC graphic adapters up to 1024x768 pixels and
also Atari 71Hz monochrome, which I am using now with it.
Here are the pinouts & stuff:
15 pin mini D-sub (NEC 3D)		15 pin D-sub (Mac, at least Quadra)

Keywords: Mac IIcx, internal, hard disk drive, SCSI
Yes, it is possible to add a second hard drive to a mac IIcx internally. This
is definitely not a recommended procedure by Apple but I have done the equivalent to my CX after upgrading it to a Quadra 700. The power supply is still the
stock CX's and it was able to power two Quantum LPS drives, a PLI SCSI
accelerator, a Micron technologies 24 bit video board, Daystar QuickCache,
New Technologies Overdrive and 20 meg of RAM simultaneously.
I added a new mount for the drive by attaching angle brackets to the drive
tower. The internal SCSI cable was changed to a longer flat ribbon cable onto
which I added an extra connector about midway. The final HD was internally
terminated and the drive between the motherboard and final HD had its terminator resistor packs removed. Cooling has not been a problem and no SCSI problems
occur with either the PLI SCSI chain or motherboard SCSI hooked into the two
internal hard drives.
It works very well for me, but proceed cautiously if you wish to do the same.

I have read one report of a brave soul who rewired the 40 mhz clock and a higher
speed clock oscillator's outputs through a double throw switch to allow different
speeds. There was no mention of any attempts to switch speeds on the fly but
if the SI uses timing loops anything like a Quadra for accessing its floppy
drive, dynamic switching will wreak havoc. A Quadra must reboot after having its
clock speed significantly changed or it will be unable to properly access its
floppy drive.

On a serious note, I have heard the tales about SyQuest failures.  But I
am curious about Jon's comments on cartridge wear for the the Bernoullis.
Can someone elaborate?  Is there a general consensus that the 128M opticals
are the most reliable?  I am mostly concerned about media failures, as

I'm having exactly the same problem.  Again, it's fine when I switch to 16
colors or a smaller monitor.  My configuration is:
Model: Centris 610 with 4 MB/80 HD, 512 VRAM, no cards
Monitor: MAG MX15F with 16" monitor adaptor (for resolution of 832*624)
I just discovered the problem a little while ago after plugging in my
new MAG monitor.  It seems to appear either when scrolling through a
window or when using Alpha or Word and I enter <return>.
My guess is bad VRAMs as well.  I really hope it isn't a design flaw.  Is
anyone at Apple listening?

if you have a memory card installed that's not one of apple's, this

You're not going to like this, but if memory serves me, postings
I've read in this newsgroup and elsewhere indicate that there are
no, repeat no, internal modems for the Duo besides the Express
Modem... at _any_ speed.  Something having to do with the modem
using the main CPU for some of its tasks, and Apple not releasing
details on the architecture, or something.  I'm vague on the
details, but the gist was that there are going to be no
third-party internal Duo modems.  If I'm wrong, somebody please
correct me on this.  Sorry to be the bearer of bad news.

I think you meant Quadra 800 ..... (but a Centris 800 probably

Hello fellow humans, and other net creatures...
If you're at all interested in this merchandise, please e-mail me:
djk@ccwf.cc.utexas.edu
I'm compacting my system and moving to a single monitor system, so I have
two monitors and cards for sale. Nothing at all is wrong with these pieces,
I'm just wanting to conserve desk space, and get all of my info from one
screen.
I'd prefer to sell to people near Austin and surrounding areas (within
driving distance - like an hour away perhaps), but I CAN ship to you if you
don't live near here. Only problem is that I didn't keep the original boxes
for the monitors, but I'm confident that my few months of full-time service
in the shipping room will enable me to safely package the monitors and
flip it in your direction.
Details:
Mirror Full Page Display (monochrome) w/nubus card:
---------------------------------------------------
**SOLD**
Sony 1304 14" color monitor:
----------------------------
What's to say? It got top ratings in last year's MacUser report. It's a SONY,
Trinitron, arguably the best (but I'd rather not argue that point).
It's a great monitor, in great shape, but I'm going to a bigger screen,
and although I'd like to keep it, finances don't justify it.
Still selling for $599 at MacLand (where I bought it originally - not
including shipping), will sell for **$475** (plus shipping). Again, make an
offer if that sounds unreasonable.
RasterOps 24si (24-bit accelerated, hardware zoom/pan, 4 meg RAM):
------------------------------------------------------------------
Renamed the 24sx a few months after I bought it, this board is for 13"
monitors, providing **accelerated 24-bit**, hardware zoom/pan, NTSC mode
(you can plug it into something like the RasterOps Video Expander and output
NTSC), and 4 RAM slots that use 1 meg or 4 meg SIMMS for GWorld RAM, or a
RAM disk. Software included for such functions. 4 meg of RAM included (1 meg
SIMMS).
Selling for $605 at Bottom Line (without the RAM - add $100), I'm asking
**$525** (shipping included this time, it's just a card). Original box and
packaging. I'd actually prefer to sell the Sony monitor and this card
together, so if you want both, drop me e-mail and make a "bundled offer"
for these items.
------------
Cheers.

MultiTech Multimodem II (9600 data/fax)
U.S. Robotics Sportster (9600 data)

The IIIP has just been superseded by the 4M, which is the one I am using at
work.  The quality of the print is execellent, beating 300 dpi printers hands
down.  In Australia the price of the 4M is about comparable with that of the

I have no experience with this particular hardware, but
just about every month in Macworld there is an add for
an combined SE accelerator/Video board.  This item sells
for about $1000 and comes with a 25MHz 68030/68882 pair,
eight SIMM slots, and a grayscale 21" monitor.
This accelerator plugs into the SE's lone expansion port
and thus no soldering.  You will however, need a long
TORX wrench to get the case open (but that's not really
a big deal).
Does that sound like what you were looking for?

According to the official documentation, failure to use the IIfx terminator
can not only affect SCSI bus performance but can also damage the bus.
Whether this is your problem or not I don't know. I have had sporadic SCSI
problems with my IIfx since I bought it. (I cannot connect more than three
devices, fourth one causes major problems).
First thing to do is to try to reformat your drive on someone elses system.
If you continue to get errors it is probably the drive. If it formats fine
then I would try to format it on your system with no externals. If this
fails then the SCSI controller on your IIfx needs repair/replacement.
Hope this helps.

portables, and they're selling for $300 LESS that the PB 100s. What I
want to know is: what are the differences between them? All I know is
that the Portable is heavier, but the PB100 doesn't have an internal
drive. Here's what I NEED to know:
Does the portable support Appletalk/network connections?
What's the CPU inside a Portable? (68000?)
DOES THE PORTABLE SUPPORT SYSTEM 7?????????
What's the maximum memory capacity of the Portable? Can you still get
RAM (meaning: does it use special SIMMS?)
What kind of internal HD does it use?
Does the Portable have a better screen?

I think that there do exist NuBus expansion cages (I'm sure I've seen
them advertised occassionally), but I think that the main problem is that
they cost much more than the difference in price between say a LC and IIvx
so unless you need lots of NuBus slots its not worth the bother.
(Of course, it may be that these extra boxes are so expensive because
no one buys them because they are so expensive...)
NuBus technology isn't a special Apple Proprietry thing (I have this
sneaky feeling that it is licensed from Texas Instruments???) so there
is no problem building an expansion box.
The difference between NuBus and PDS is that NuBus is a clever interface
with lots of neat toys built in to make sure that lots of cards can work
together on the same computer. PDS (processor direct slot) is just that:
here are all the connections to the processor. You can do anything with
this and it is as quick as it can be, but there's no cooperation. You
may be able to get double PDS slot adaptors but you try plugging 2
video cards in, and just watch them conflict! Of course, the extra
electronics in a NuBus slot makes it appreciably more expensive, so
guess why Apple doesn't put it in it's cheaper machines?
So, yah pays yer money and yah takes yah choice.

You probably want to hard-wire the SCSI ID with shorting jumpers.  Put
it at a convenient number like "1".  You *could* cut a hole in the
back of the machine to route the ID switch, but why go through the
hassle?  You probably won't be needing to frequently change the ID of
your internal drive.

Yeah, when I first installed the tape drive I was a little concerned
too.  But it's no problem, the device is designed to fit just fine
with the overhang.  It shouldn't reach back beyond the ROM/RAM/VRAM
SIMMs, though.

You can special-order parts to mount the device from your local Apple
dealer.  The relevant parts are:
922-0358  blank bezel faceplate
922-0850  CD-ROM carrier [i.e., generic 5.25" device mounting bracket]
Note Apple's unfortunate choice of name for the slide-in bracket to
mount a 5.25" device.  The service techs I talked to said, "Oh sure,
we stock those."  Of course they were thinking of the CD caddies to
hold a CD disk when you stick it in the drive.
As far as I can tell, Apple does not sell a bezel faceplate already
cut out for a standard 5.25" device.  (Why not?  They advertise
these machines as being able to accept any standard device in the
5.25" bay, why not provide the faceplate?)   They do sell a cutout for
their CD-ROM drive (of course), but that's of no use.
I'm going to hack up the extra bezel I ordered to make a cutout for my
tape drive, which is a standard 5.25" device.
Good luck with your SyQuest.

If Apple didn't put out such a good product -- I'd gladly take my
business to -- to -- the 8-bit Ataris.  I think the
situation with the Express modem is inexusable for any business.
I've had mine on order since January.  Apple finally called me last
week -- to tell me that I should have it "by the second week of May."
In the meantime, I've been stuck with my Duo210 without the
connectability I needed it for.  I'm sure there are plenty of people
who can bite back at me, citing all sorts of reasons why Apple is
right or at least justified, but I'm just a crabby consumer and
when I order a "Duo210 with modem" that's the product I expect.
Oh, well.  It's not like it's limited to the computer biz.  Remember

(total of all extensions) then my system will crash before the finder
comes up.  What I meant was having a large amount of fonts load, or
sounds, or huge disk caches with a control panel other than Apple's
memory control panel.  Apple's cache is at 64K, mode 32 is on, and
so is 32 bit addressing.  All extensions work by themselves or with the
others until I increase the memory used by some of them (with methods
mentioned above).
Well, here's my latest followup...  I ran NOWs System Profile and got

Hello Mr. Au,
I have to disagree regarding your assessment of Macintosh in Hong Kong. The Mac has a sizeable share of the typesetting market, as in the U.S. A local magazine, Next Magazine (similar to Newsweek here), uses the Mac extensively. I have seen Sir Speedy and other franchises in Hong Kong equipped with Mac-based systems. True, the discount is not as steep as here because customers in Hong Kong cannot buy from gray market, nor are Mac being sold thru mass merchandisers like Apple does here with the Performa lin
e. At this point the sale of Mac is handled by one exclusive distributor. On the other hand, you can always get a PC clone or in the earlier days, illegal clones of the Apple IIe.
Your perception of the Mac not being too popular in Hong Kong is simply because most hobbyists and users find it much cheaper to go to one of those basement stores that sell PC clones with probably illegal copies of BIOS than to pay for a Mac.
Similarly you cannot say Lotus 1-2-3 surely is not well accepted in Hong Kong because the sale is so low. May be it is because of all those places in Kowloon where illegal copies of Lotus 1-2-3 can be bought for $20 and $10 for a professional looking but illegal copies of the manuals.

Specs for the 68040 can fill a 500 page book.  Some highlights are...
32-bit address space w/ 32-bit data width.  18 32-bit integer registers
& 8 80-bit floating point registers.  8K copyback capable caches,
4-way set associative.  Typical 1.2 clocks/integer instruction.  5
clocks for a floating point multiply.
(interesting aside: the 68040 can multiply two 80-bit floating point
numbers in less time than it can multiply two 32-bit integers)
>2) Specs for the 68060 with estimated cost, release date, etc...
More of the same but with multiple instruction dispatching.  Figure
about 0.8 clocks per instruction typical (my guess).  But the Motorola
guys are pretty bright, it may be less.

Call Motorola.  I'm not typing it all in.
>I am hoping that the 68040 can win yet another battle against the intel people.
I'm predicting that both the 680x0 and x86 lines are reaching their
ends.  New experimental processors have 64-bit data pathways and can
schedule up to 8 out of 32 instructions each clock cycle.  That sort
of trick can't really be done with CISC architectures.
I finally saw some details on the 586/Pentium and was not greatly
impressed.  They've finally done some work on the FPU to get it up to
speed, but otherwise it's only going to be a 2x speedup.  And to get
that they're using two integer units, larger caches, and a branch
target buffer.  Yes, I know they're talking about 100MHz processors.
Big whoop.  Designing a 100MHz board is difficult and really
expensive.  Priced 15ns memory chips lately?

060 fastest, then Pentium, with the first versions of the PowerPC
somewhere in the vicinity.

No.  Computer speed is only partly dependent of processor/clock speed.
Memory system speed play a large role as does video system speed and
I/O speed.  As processor clock rates go up, the speed of the memory
system becomes the greatest factor in the overall system speed.  If
you have a 50MHz processor, it can be reading another word from memory
every 20ns.  Sure, you can put all 20ns memory in your computer, but
it will cost 10 times as much as the slower 80ns SIMMs.
And roughly, the 68040 is twice as fast at a given clock
speed as is the 68030.

After comparing the above strings with my AT commands reference guide, I
came up with:
ATZ0L2N2X5&D0S11=50^M
This is entered in the 'Initialize' box on the 'Modem Preferences' in Zterm.
Quick summary of each commmand:
Z0	- Reset modem to User Profile 0.
L2	- Speaker volume at 2 (fairly quiet)
N2	- Ring volume at 2 (fairly quiet)
X5	- Display connect info according to setting 5 (see manual)
&D0	- Assume DTR (computer) is always on
S11=50	- Dial speed at 50 (as fast as ZyXEL can handle)
In FirstClass, I used this same string, with the addition of S0=0 right
before the S11 command, in the setup box.  This disables the auto-answer
function of the modem for FirstClass.  I based my modem setting on the Supra
14.4FAX, and just changed the above mentioned string.
In Telefinder, I based my setting on the Zoom V42 - HH setting.  I changed
the 'Modem Initialization' string to the same one I used for FirstClass, and
everything seems to work fine.
Sorry it took so long to get this summary out.  If someone wants to forward
this to the /info-mac/reports directory at sumex-aim, it might save other
newbie ZyXEL users like myself the trouble of setting up their strings, and
also save the net some redundant messages.  If anyone else has something
to add, feel free.

Hi everyone. Just the other day, I ordered a VRAM chip for my new LCIII from

and we found that it didn't work properly. When you put the computer in

My question is, how often does such a thing happen with SIMM chips in general?
Do you often find when ordering chips that a large portion are bad? Is this
a rarity? This is the first chip I've ordered so I have no other experience

experience.
That's about it. Please email me, and if people want, I can post a summary.

Here is the story:
I have a network with 4 Macs on Localtalk. One of them has an
Ethernet Card, and is currently connected to a NeXT (don't laugh
I got it for the price of a Mac IIsi). The NeXT is connected
to the internet over SLIP running on a 9600 baud modem.
Currently, we can telnet from the Mac w/ Ethernet to the NeXT,
and then telnet out again to the rest of the world.
What we want to know is if there is some sort of hardware that
will route telnet sessions from the Localtalk Macs to the NeXT
via the Ethernet Mac. From what we have heard, AIR doesn't do
the trick.
Software solutions would be good too, but my impression is that
there aren't going to be any.
Our immediate interest is to be able to get to the NeXT and telnet
out again. The SLIP connection doesn't allow us to assign IP numbers
to machines, so everyone shares that 1 number...oh well...
thanks in advance.

a few years ago, for a Nubus board that had umpteen SIMM slots, to be
used to "recycle your old SIMMs," when you upgraded memory.  I don't

any of the latest Mac magazines.  It mentioned that it included software
to make the SIMMs on the board act like a RAM disk. As someone who has SIMMS
he can't get rid of/use, but hates the waste, this sounds to me like a majorly
good idea.  Does anyone out there know what board/company I'm talking about?
Are they still in business, or does anyone know where I can get a used one
if they are no longer made?  Any help would be greatly appreciated.  Please

I can't say for sure with the IIvx -> C650 upgrade, but I wondered the
same thing when I ordered my LC -> LC III upgrade.  Turns out the "upgrade"
is actually an entire CPU minus any disk drives.  You pull the floppy and
hard drives out of the old one, stick them in the new one, and you've got
an LC III.
The IIvx -> C650 may be the same thing.
It might be something to look into for those people who are unhappy that
Apple only sells Macs pre-packaged with the drives.  Of course, the price
is quite a bit higher without the trade-in...

Hi there,
Does anyone know why Apple has an ambiguous message for
C650 regarding fpu?  In all Mac price lists I've seen, every C650
has the message "fpu: optional".  I know from what we've discussed in this
newsgroup that all C650 have the fpu built in except the 4/80
configuration.  Why would they be so unclear about this issue in their
price list?
I'm planning to buy the C650 8/230/cd pretty soon, but I'm now getting
confused with whether it comes with fpu or not.
Why say "optional" if it's built in?
Please, anybody help me understand this game.
Regards,
Thian.

Anyone out there have a Sony 1304S?
I have one, and it's very nice, however - If I run it in 16" mode, the
picture won't
go very big. I end up with about 1" gap either side, and .5" top &
bottom. I suspect
an internal adjustment would fix this. Anyone tried it?
Another problem is sub-brightness: Areas that are meant to be black (or
off the main
raster) are not very black. The real raster is quite visible when the
screen is blanked.
This is not too severe, but it is just not as good as other Trini screens
I have
used. If I turn the brightness/contrast down so that the raster is not
visible, the
real image virtually disappears!
The raster size is just right if I use 1024*768, but 100dpi+ is a bit too
much!
Oh, and I am using a RasterOps 24XLi card.
Thanks

I'm having exactly the same problem.  Again, it's fine when I switch to 16
colors or a smaller monitor.  My configuration is:
Model: Centris 610 with 4 MB/80 HD, 512 VRAM, no cards
Monitor: MAG MX15F with 16" monitor adaptor (for resolution of 832*624)
I just discovered the problem a little while ago after plugging in my
new MAG monitor.  It seems to appear either when scrolling through a
window or when using Alpha or Word and I enter <return>.
My guess is bad VRAMs as well.  I really hope it isn't a design flaw.  Is
anyone at Apple listening?

In a resent article in one of the macMags I think a 50mHz 030 accelerator was
slightly slower than a 25mHz 040 accel. But, this is using a system designed
for the 030. So, It stands to reason that a system designed for an 040 ie
quadra) would do better. So overall I'd figure 040 = 030 * 2.5 or so.
Along the same lines the new POwerPC stuff is supposed to run the system
at the level of a fast quadra, but system 8 or whatever will allow 3 times the
speed of a 040 in the powerPC based systems. and wait for the 680060. I think
it laps the pentium.

Well Bill, There are 2MB soldered on the logic board and 2MB in the RAM
expansion slot giving you 4MB. The only thing you can do to upgrade to
the maximum Ram is to remove the 2MB expansion and install a 6MB expansion,
giving you a total of 8MB which is the max on a 170....You can try calling
TechWorks, or any other memory vendors out of MacWeek, MacWorld...etc....

For the most part, this is a bunch of bunk.  I've got a Computer Engineering
degree, yet I've spent the last 7 years writing software that people actually
use.  Moreover, the salary distinctions are incorrect; I received 3 job offers
upon graduation; the two jobs that actually used my hardware experience were
$7000/year lower!  My advice is to decide which classes and projects most
interest you, and pick the major that allows you to take them.

I also suffer from these video "artefacts". My configuration is a
Centris 610, 4/160, 1MB VRAM with a NEC 4FG. It only happens at
832x624, in 8bit colour with virtual memory off during scrolling. This
occurs when the VRAM SIMMS are installed as well as removed.
It seems that the 610 does not like 832x624.

To boorishly reply to myself, I found I did have the Instrutech information
already. The specs (to use the term loosely) are as follows:
A/D: 16 bit converter, with 14 bit accuracy to 100 kHz, 12 bit accuracy to
200 kHz. No specs for S/N, monotonicity, linearity. There are 8 multiplexed
inputs sharing the single A/D, so that all inputs are not samples at the
same time, and in the above conversion specs the all-channel sample rate
must be used. Thus, for two channels, you only have 14 unknown quality bits
at 50 kHz per channel. This is poorer quality than the national
Instruments, at the same sample rate.
D/A: 16 bit converter. No specs for S/N, monotonicity, linearity. Each of
the 4 output channels has its own converter.
The price for the external converter box (the ITC-16), the NuBus interface
board (the MAC-23), plus C driver software and Igor XOP's is $2695. Rather
steep.

I think this kind of comparison is pretty useless in general.  The
processor is only good when a good computer is designed around it adn the
computer is used in its designed purpose.  Comparing processor speed is
pretty dumb because all you have to do is just increase the clock speed
to increase speed among other things.
I mean how can you say a 040 is faster than a 486 without
giving is operational conditions?  Can you say the same when
you are running a program that uses a lot of transidental functions.
Knowing that 040 does not have transidental functions building in to
its FPU and 486 does, can you say that 040 is still faster?
Anyway, I hope people do not decided upon wether a computers
is good or not solely on its processor.  Or how fast a processor is
based on its name, because one can alway do a certain things to a
processor to speed it up.
But if we restrict our arguements to, for example, pure
processor architectural issues.  Or how one processor will work
well and another will not based on its design, then we can get
somewhere with our discussions.

Not a good idea to compare processor power. Doesn't make sense for real

Intel chips have traditionally been faster than their Motorola "equivalents"
although the significance of chip speed in real world application performance
is something that is highly debatable.

Not in a clock-doubled system. There isn't a doubling in performance, but
it _is_ quite significant. Maybe about a 70% increase in performance.
Besides, for 0 wait state performance, you'd need a cache anyway. I mean,
who uses a processor that runs at the speed of 80ns SIMMs? Note that this
memory speed corresponds to a clock speed of 12.5 MHz.

Well here is my $0.02 worth.  Advice from a grad student.
I agree with the gentlemen who wrote the comment before me.
The important thing is pick what ever interest you the most and
learn as much as possible about it.
In my five years of education in this field, though brief
compare to alot of people, I had to think about this kind of
question a lot.  Did I make the right decision in going into
Electrical Engineering as opposed to Computer engineering or
CS?  The more I go thru school, the more I believe that this
kind of question is irrelevant.
I have come to believe that choosing CS because one
does not like hardware or choosing hardware because one does
not like to program is really doing an injustice of building
and computer and making it useful for something.  Everything
is interwoven and inseparable.  CS, CE, and EE are all a
part of a really great discipline and do depend on each other.
My advice is don't limit yourself, but make a decision
based on which major will give you the best opportunities to
learn.  That of course depends on the curriculum at your
persective school.  I would choose a major that allows me to
explore as much as possible.  Beside, I don't know why the
school would make a student choose a major before her/his
sophamore year.
Hey you may be so interested in this field that you
decided to learn all about the making of computers in which
case, you suffer a little more and go to grad school.
About the money.  Don't look at the averages, if you
are good, you are going to earn more money than anyone else.
If you are a superstar programmer, you will earn millions.

Summary: Instructions for Quadra 700 memory installation
Keywords: memory,quadra,700,install
This is turning into a FAQ
Here is how to violate your Quadra 700 warranty and install your own
memory.
1)  Insert usual disclaimer here
2)  Remove the top lid of the machine. You will see the floppy disk and
hard drive mounted in a plastic tower. Follow the usual anti-static
precautions and of course make sure the machine is OFF when you do
this. Unplug the wall and monitor power supply cords from the back
of the mac.
3)  Remove the power supply by pulling the plastic interlocking tab on the
tower forward and simultaneously pulling the power supply straight up.
The tab is a piece of plastic from the left posterior aspect of the
tower which extends downward to hook on to the power supply. You may
also feel a horseshoe shaped piece at the right portion of the power
supply. Leave that alone. The plastic tab from the tower is all you
need release.
4)  Look at the rear of the tower assembly. You will see the flat ribbon
SCSI connector to the hard drive, a power cable and a flat ribbon cable
leading to the floppy drive. Disconnect all these from the motherboard.
The hard drive power cable connector has a tab which must be squeezed
to release it.
5)  Unplug the drive activity LED from its clear plastic mount
6)  Look down the posterior, cylindrical section of the plastic tower. A
phillips head screw is at the base. Remove it, taking care not to drop
it into the case. A bit of gummy glue on your screwdriver is helpful
here.
7)  Remove the tower assembly by pulling medially the plastic tab on the
right side of the tower. This tab prevents the tower from sliding
posteriorly. Slide the entire tower assembly 1 cm posteriorly then
lift the tower assembly straight up and out of the case.
8)  Congratulations, you have now gained access to your machine's SIMM
slots.
9)  The six big slots are for VRAM. One usually must install all six to
gain useful video modes. All SIMMS (RAM or VRAM)  installed with their
chips facing the front of the motherboard.
The four smaller sockets in front are for RAM SIMMS. Install SIMMS in
sets of four into these sockets. Be sure you seat the SIMMS squarely
and firmly into a fully upright position.
10) Reinstall the tower assembly by first placing the right wall of the
tower against the right wall of the case with the tower assembly about
1 cm posterior of its intended position. Lower the tower assembly into
place while maintaining contact with the right wall of the case.
Once fully down, slide the tower assembly anteriorly until it clicks
into place.
11) Reconnect the motherboard ends of the cables. DONT'T FORGET THE FLOPPY
DRIVE CABLE.
12) Replace the phillips head screw
13) Drop the power supply straight down into place until it clicks in.
14) Plug the hard drive activity light back into its clear plastic mount

Yes, quite a number of people it seems from discussions I've had (me
included). I bought my machine a couple of weeks ago as well and
started to experience these problems.
Apple Australia via my dealer said that this problem has a number of
potential causes - Faulty applications, faulty third party hardware
(modems, memory etc), system software, PRAM corruption and power
manager corruption, and the Duo hardware itself.
None of the above are relevant in my case except the last two maybe
(no applications were running, the system software was re-installed, I
have no additional hardware). I have found that clearing PRAM appears
to help for a while at least (hold down command option P and R on
startup). Unfortunately the problem returns suggesting that PRAM is
being corrupted by something (system software bug ? - I don't have any
non-issue inits in my system). Apparently the Power Manager can be
reset by "holding the reset and interrupt buttons while powering up" -
Apple's advice - but since the Duo does not have an interrupt button
I'm not sure what they mean in this case. This may also help if
someone can decipher Apple's advice for me.
Beyond this Apple suggest that " you should follow the technical
procedures to check the hardware of this Duo". Since so many others
appear to be having the same problem it would seem to me that there
has been a system software bug introduced somewhere along the line -
and quite recently too - since it only seems to be recent Duo 230
purchasers who have this problem.
Any more comments from others in the same boat are welcome,
particularly Apple Duo engineers :-)

But the interesting comparision is how fast clock-cycle chips
you can get - an Alpha is WAY slow at 66 MHz, but blazes at
200 MHz.

>As far as the 486DX2-66 goes - 32 SPECint92, 16 SPECfp92 .
But the 68040 is (or will soon be) available in 40 MHz version,

I think you have that one turned around; they have faster clock
cycles but less power behind each cycle. Not to mention that the
Intel instruction stream is BYTE-oriented (longest Intel instruction
is 15 bytes; what an odd number :-) which makes it hard to do any
intelligent memory subsystem.

Subject: Asante EN/SC hangs SCSI devices
Reply-To: behr@math.ilstu.edu (Eric Behr)
Organization: Central Illinois Surfing Club
Lines: 31
I just hooked up my Mac IIsi to a relatively old (1 year?) Asante EN/SC
adapter. The 10Base-T connection works like a charm. I installed the
newest drivers from Asante's ftp server.
The problem begins when I attach one more device to the SCSI chain -
specifically a 50MB drive. I power up the drive, then the Mac. The Mac
tests memory, etc. Just before the "happy Mac face" normally shows up, the
power light on the EN/SC goes out, and the boot process stops. So I can use
the network, or the external drive, but not both at once. This makes the
Asante box pretty much unusable.
It doesn't look like a purely electrical SCSI problem, because if I turn
on the drive just a second or so too late, so that it doesn't get noticed
during the initial SCSI polling, the Mac boots normally and the adapter
works, even though the hard disk is powered on and connected. The Mac has
*never* once failed to boot from its internal drive up to now (and I've had
it for over a year).
Here is what I tried: changing the SCSI ID's of the EN/SC and the disk --
several permutations; changing the order of devices, i.e. the EN/SC at the
head or tail of the chain; overterminating with an external terminator
(both devices have internal ones); underterminating, i.e. removing internal
resistors from the hard disk; trying another EN/SC box; trying another
identical drive; trying several different SCSI cables.
Has anybody seen this? More importantly, does anyone have a solution?
Thanks a lot.    E.

Applied Engineering makes a NuBus card called the QuadraLink which is
a board that contains 4 serial ports, which I believe can be used
simultaneously.  I'm not a user of one of these, but I have installed
a couple for people at work (I'm a technician).  Hope this helps.

I have ordered several Macs from different mail order companies with absolutely zero problem. You have to dig around to find the true gray market dealers that sell Macs with authentic serial numbers untouched. There are value-added dealers (nothing to do with VAT, no flame please) that are very legitimate.
CDA unfortunately is one of those that replace the serial number with their own to prevent Apple from tracing which authorized dealer sold that machine to CDA.

How do you calculate that figure? I'd assume even in personal computers

The previous article referred to the fact that you could only use 20ns SIMMs in
a 50MHz machine, but that you could use 80ns SIMMs in slower machines. I just
pointed out that if you could only use 20ns SIMMs in a 50MHz machine, you can't
use 80ns SIMMs in anything faster than a 12.5 MHz machine. Bank switching and
caches were not considered in either example (although both would help memory
access).

If you get the Centris 650 with CD configuration, you are getting a Mac with
a 68RC040 processor that has built-in math coprocessor support.  My
understanding is that the "optional fpu" refers to your option of purchasing
the Centris 650 4/80 without FPU OR one of the other configurations WITH FPU.
Apple does not offer an upgrade from the non-FPU system to become an FPU
system.  And, it is unclear whether the '040 processor on the non-FPU system
(a 68LC040) can be replaced with a 68RC040 supplied by another vendor.
Apple did send a memo out at one point sating that the Centris 610, which ONLY
comes with a non-FPU 68LC040 processor CANNOT be upgraded to support an FPU -
the pin configurations of the two chips apparently do not match so you cannot
swap one for another (again, according to Apple's memo).
Hope that helps.

This can be caused by two one of two things.  The first and easiest to fix is
interference from something around the monitor, such as another monitor or
other electrical device.  Try moving the system to another location to fix
that problem.
Second, because of the scan rate of the monitor, it tends to synchronize with
room lights and can cause the interference you are seeing.  Try turning off
all lights in the room(s) around the system and see if that helps.  If not,
try moving the system somewhere else.
A third solution would be to get a 14" Apple Color Display - It should not
have the same problem the 12" Color is more suceptible to.
You can try calling Apple's new support number (in the U.S.) at 1-800-SOS-APPLE.
This number is for ANYONE who has questions regarding Macintosh setup and
compatibility and just went into effect for this extended support on Monday,

How many NuBus slots do you have?
Applied Engineering has something called the QuadraLink, which is
a card with 4 serial ports that you get at through the comms
toolbox (in addition to the built-in ones) It also comes with
software for fooling applications to open an AE port when they
think they open a built-in port.
They also have a more expensive card with DMA (better performance)
and I _think_ they, or someone else, have a card that handles
8 ports simultaneously.
As I said, with NuBus, you're green. Learn how to use the Comms
Resource Manager to get at the various installed cards.

Perhaps the reason is simple--maybe the marketing people who put together
the brochures and price lists weren't clear on the FPU issue.
Afterall, Apple's literature is not always 100% correct. A funny one I
noticed recently is that some of the brochures on the Macs with CD
capability refer to the "auto inkjet" feature. This should have read "auto
inject" feature (as it does on some other correct brochures I've seen from
Apple). Since it was correct on some older brochures, I can only guess
that someone edited the copy, saw "inject" and thought it was a typo and
changed it to the more familiar word "inkjet".
Hmmm, what would that be? A printer built into the CD player? A way of
*writing* information to a CD? :-) :-)

My mac monitor displays about 20 vertical lines when I use it.
It means that either my display memory goes wrong or monitor is bad
or video card is bad.
I checked my monitor, it works fine with other Mac.
I checked my video card, it's also fine.
I replaced all the RAMs, it still didn't give me right answer.
Hence I assume something wrong with some part of my motherboard.
I don't know hardware architecture of the Macintosh.
Can anyone tell me what's the problem ????
It's a Mac IIcx.
MANY THANKS IN ADVANCE.

Hi.  I think I have a problem with the stereo sound output on my Quadra
900, but I am not totally sure because my roomate has the same problem
on his PowerBook 170.  Any info or experience anyopne has would be
greatly appreciated.
When I hook my Quadra up to my home stereo system, the following types
of sounds (mono, as far as I can tell) all play fine through BOTH
speakers:
system beeps  (already provided ones such as Indigo and ones I record)
Armor Alley
Spectre
Spaceward Ho!
But, the following games only play out of the left channel:
Lemmings
Out of This World  (awesome game, BTW)
Glider 4.0
OIDS
But still, STEREO system beeps do play in stereo, through BOTH speakers.
(The one I'm specifically referrring to is Apocolyptic Beginning, which
my roommate downloaded from some ftp site (sumex?))
All of the symptoms are the same on my rommates 170 (he can't run
OOTW because he doesn't have color).
We're both running system 7.1
Does anyone with Lemmings or the other three games I mentioned above get
sound out of both speakers on a Mac II class, Quadra, LC, PowerBook 140 or
greater, Centris, SE/30, etc... (stereo) machine?
I used to have a Mac II, and I sort of rememeber Lemmings playing in
stereo on that machine, not just on the left channel.  (I could be
mistaken, though.  If there were a problem with the Quad 900's and PB
170's, I am wondering why the system beeps still play in stereo?  If there
isn't a problem with our machines, I wonder why the 4 games above are
apparantly written to support only one channel of stereo when they
could just use mono sounds so the mono sound would at least come out of
both speakers  (like Spectre, etc. do)?
Quadra 900's and PowerBook 170's have the same ROMS (to my knowledge),
so maybe this is a ROM problem?  (if so, though, why wouldn't System 7.1
patch over this problem?)
Thanks for any help you can provide!

I had the same problem with my 512 a long time ago.  Resoldering
the joints on the motherboard (all of them) fixed it.  Turns out
that continuous heating and cooling caused annular (ring-shaped)
cracks to develop in the solder, effectively cutting the video
circuitry off.  If you're not a solder-jockey you might want to
have someone else do it -- I took mine to an electrical engineer
buddy -- but it was a 20-minute job, tops.

Bad RAM brings some Duos down. (random access memory boards for Apple
Macintosh PowerBook Duos)
MacWEEK v7, n7 (Feb 15, 1993):132.
COPYRIGHT Coastal Associates Publishing L.P. 1993
By Raines Cohen
Austin, Texas - Some third-party memory-expansion cards for PowerBook
Duos depart from Apple specs in ways that could cause crashes, data loss
and other problems.
Technology Works Inc., a RAM and network vendor based here, last week
issued a warning about three problems it said it had found in Duo RAM
products from some competing vendors, which it declined to identify.
Other vendors and an Apple spokeswoman confirmed that the problems exist.
> Self-refresh.  The Duos require a kind of dynamic RAM called
selfrefreshing, which can recharge itself while the system sleeps.  But
Technology Works said some vendors have sold Duo cards with
nonselfrefreshing DRAM, which can cause the system to lose data or fail to
wake from sleep.
Most leading memory manufacturers include the letter V in the part
number stamped on their self-refreshing chips; nonself-refreshing chips
instead have an L, according to TechWorks.  The chip label, however, may
not tell the whole story.  Newer Technology of Wichita, Kan., said it uses
nonself-refreshing chips but adds its own circuitry to keep them refreshed
while the Duo sleeps.
> Speed.  Some RAM-card vendors have put 80-nanosecond DRAM on Duo
cards rather than the 70-nanosecond type the 230 requires, Technology
Works said.  However, some chips labeled as 80- or 85-nanosecond are
certified by the manufacturer to run at a higher speed.
Kingston Technology Corp. of Fountain Valley, Calif., said it offers
Duo RAM cards with 80-nanosecond chips, but only for the Duo 210, which is
compatible with the slower chips.
> Space.  Technology Works charged and Apple officials confirmed that
some third-party cards are too large to fit properly, forcing the corner
of the Duo keyboard up and preventing the system from starting up normally
when in a Duo Dock.
Lifetime Memory Products Inc. of Huntington Beach, Calif., said it
originally shipped cards with this problem but has since offered all
customers free upgrades to cards that fit.

Mac sound hardware is diverse; some macs play in stereo and
mix the output (the SE/30 for instance) while others play in
stereo but ONLY has the left channel for the speaker, while
some are "truly" mono (like the LC)
Developers know that stuff played in the left channel is
guaranteed to be heard, while the right channel isn't. Some
send data to both, some only send data to the left channel
(the first is preferrable, of course)

I'm a system and network admin. One of my users has a Duo 230

Leaving the Duo on for several hours causes it to slow down
unacceptably. It can take 10-15 seconds to change applications. During
this time it is completely hung.  If he reboots, the problem goes away
(For a while). It seems the system is getting itself into a wedged
configuration.
He's re-installed System 7.1 and rebuilt the desktop. Neither of these
have helped.
It's possible that it's network-related, he uses Eudora which checks his
email every 10 minutes (over Ethernet). He hasn't checked to see if this
problem occurs while undocked (he's docked most of the time).
Little to no non-Apple inits, I don't want to start yanking the rest
unless I know that might *really* be the problem.
He hasn't tried zapping the PRAM, I have advised him to do that next.
Anyone who has ideas, I'd love to hear about them. I'd call Apple, but
I've found they're best to call during the week (it's Sunday evening).

I just bought a select 300 and rushed home to print
some grayscale pictures for my kids, when I discovered that
grayscale(and photograde) are not available if you are
using an SE...even if you are running with an '030 cpu.
You won't see this in the printer's docs, and the Apple
rep didn't mention it to our users group either. It seems
that SE ROMs won't support those "features". Okay, I
guess I should have somehow known that this was the case.
Let the buyer beware, huh Apple?
Be that as it may, I have been thinking about the
problem and I'm puzzled. Why  can't a defencieny in the
ROM be made up for in software. I write software for a living
(on unix platforms) and I don't understand the "it just
can't be done" responses I've gotten from those I have
asked so far.  Isn't Mode32, or somesuch piece of  soft-
ware, just such a fix.
Anyway, I was hoping someone knowledgeable
about Mac internals could set me straight: is it simply
impossible for a mac SE to print grayscale, or could
someone armed with enough info and a little pro-
gramming experience cook something up that would
supplement the ROM's capabilities?
Also, how does one know if one's mac can
support the grayscale and photograde that the Select 300
is supposedly capable of? ( Short of buying the printer
and trying it out like I did)

To use the grayscale features, I believe you need a Mac equipped
with colour quickdraw. I was told this somewhere or other, but it's
not mentioned in "Apple Facts" (guide for apple sellers), in the

Second Wave makes NuBus card cages that work on the PDS slots of at
least three Macs: the SE/30, IIsi and Centris 610. They have not, to
my knowledge, announced such a device for the LCII, but they could
make one, technologically.
The PDS card that goes to the cage simply needs the NuBus controller
circuitry present on NuBus Macs.
Why, though, does anyone care about this? dgr has a three-PDS
adapter for the LC/LCII. They will soon have one for the LCIII. PDS
is better than NuBus for most people in most applications. Granted,
there are more NuBus cards. But, most applications that require a
NuBus card (like full-motion video capture) shouldn't be done on an
LC/LCII/LCIII anyway.

I think you will find that the Mac SE can PRINT grayscale images, loaded
with the proper software. However, the Mac SE cannot DISPLAY grayscale on
its screen or any attached video because that ability is not in the ROM.
So, while you might be able to PRINT grayscale, you'd have a hard time
SEEING the grayscale image you want to print.

Battery powered devices like the PowerBook are sometimes more sensitive to
serial port weirdness.  I had trouble with connecting my Mac Plus to an HP 95LX
handheld.  Everything else worked okay on that port, but not the HP. (it runs
on two penlite batteries).  It turned out that the plus (by accident or by
design flaw?) was putting a 4 volt bias on the serial port that was doing
weird things to the HP (which has only 3v dc!).  The HP worked fine when
connected to the printer port.
Does your PB screen get dim or anything when connected to the device?  Have you
tried using the printer port?
Good luck.

Radius speculated, publicly, that they could provide a PowerPC-based
Rocket for existing Macs. It would have the plus of RocketShare and
the minus of NuBus accelerators - no true boot off the accelerator,
NuBus bottleneck to video and other I/O.
Apple, it seems, will not compete with third parties here -- except
perhaps for not-yet-available Macs like Cyclone, where a PowerPC
slot might be advertised. Look for Daystar and such to make PowerPC
accelerators.
One potential problem with any accelerator, though, is that it will
need a ROM companion and Apple has licensed only Radius, with
Rocketshare, to use any of its proprietary code.
Apple is, between the lines, trying to let us know that PowerPC Macs
will have simplified logic boards due to the magical nature of RISC
and that these boards should be much cheaper to build than those in
existing 68040 Macs. Perhaps, then, we'll see groundbreaking
prices in Mac-logic board upgrades, much the same way we've seen
much cheaper high-performance CPUs this year.
First generation PowerPCs, 98601s, will also hopefully have socketed
CPUs so that they'll be chip upgradeable to 98604s a year later.
This should be possible in much the same way that 486s can be pulled
for clock doublers. If there is too much technical   baggage (which
I doubt since the external busses are the same size/width) to do
this, perhaps we can have CPU daughterboard, a la Powerbook, as
standard to facilitate better CPU upgrades. This is an area where
Apple has fallen far behing the Intel-based world. Perhaps catchup
is in order.
By the way, last week's PC week had an excellent story on PowerPC,
Pentium, MIPS R4000, DEC Alpha (the big four on the microprocessor
front for the forseeable future). Worth reading for technojunkies.
Also, the latest PC has a cover story on Pentium. Read it, and all
the other stories about how Intel is unstoppable and preeminent
right now.
Once anyone is this secure, they are due to fall. Intel's market
position will never again be as dominant as it is today (especially
if AMD gets the go ahead to sell its 486s this week as it appears it
might). The competition from all fronts is gearing up for an awesome
battle. Apple users should be excited that PowerPC, while not
guaranteed dominance, is a guaranteed winner, even if its one of
several.

Peter, I'm sure someone out there has a better/easier way to do what you want
to do, but I'll tell you how we do it where I work. We have about 15 Macs
networked together using Appletalk and PhoneNet connectors. To chat we use a
program called 'Broadcast'. With it we can send brief messages to all or
selected machines within the network.
Hope that helps...

The DayStar PowerCache for the SE/30 replaces the CPU with an accelerated
CPU plus the powercache.  This leavese the PDS slot open for a video card.
Currenty, DayStar does not have the '040 in this configuration, but it is
due out early next year.  With their upgrade policy, you can get the '030
accelerator now, and when the '040 version becomes available, you get
credit
for the one you have.
I am running their 50 MHz version with FPU along with a Radius Precision
Color Pivot and I'm very satisfied.

Their should be no difference in the drive itself between IBM-PC and Mac.
The two main differences are the formatting of the disk itself (but with
the correct software each can read the others) and maybe the cable
(depends on your SCSI board on IBM-PC).
If you get some Mac softawre to allow mounting of ANY IBM-formatted disk
and the correct cable you should br able to mount and read your IBM-PC
syquest.
good luck,

Organization: The MacInteresteds of Nashville, Tn.
Lines: 37
Regarding the post for information about the Mac Portable and the
Powerbook 100, here are a couple of the answers:
(1) Does the Mac Portable support Appletalk? Yes
(2) What CPU is in the Mac Portable? A low power version of the 68000
running at 15.87 Mhz.
(3) Does the Mac Portable run system 7? Yes, although it does use up a
lot of memory.
(4) Is memory still availabe for the Portable? There are several vendors
that still make RAM for the Portable. There are two options: Some vendors
sell memory that plugs into the RAM Slot inside the portable. Others sell
memory that plugs into the Processor Direct Slot. Either way, the most
memory you can address is either 8 or 9 megabytes, depending on whether
the Portable is Backlit or not. King Memory and Peripherials in Irvine
California is the cheapest place I know of for Portable memory. 2MB -
$140, 4 MB, $250, and 7 MB $415. I still see several ads in macuser that
are selling 4 MB modules for $450. Wide variety in pricing here.
(5) What is the internal HD? Its a Conner CP-3045 40 MB HD with an
average access time of about 25 ms.
(6) Is the screen better that the PB 100? Heavens yes! The PB 100 is a
backlit PASSIVE matrix screen which means it fades out on you if you move
your head a few degrees left or right. The Portable has a backlit or
non-backlit ACTIVE Matrix screen which I think is a joy to read.
Other things to consider - Where to get the portable and how much to pay
for it? A good supplier has been SelectTerm in Mass. They were willing to
sell a 2MB Non-backlit Portable with an internal 2400 bps modem for about
$650. Or a 4 MB Backlit Portable with an internal 2400 bps modem for
about $900.
The answer is call around for a good while or you'll pay too much.
I'm still looking for an internal FAX modem for the portable? Anybody got
one they want to sell? -- Good Luck, Gene Wright

Hi everyone. I recently posted about how I received a bad vram chip for my

I'm wondering if anyone can interpret these codes for me, so I can figure
out what type of chip MacConnection sent me.
Each chip says: M518121A-80J
2515251
On the back of the card, it says 0593
I believe from the numbers that means it is an 80ns chip, but I can't figure
out what the size is supposed to be. If anyone can help, I'd be grateful.
Please email me your response. Thanks a lot!

If you use System 7, you can use my application Zing which has
a 30 kB footprint (meaning you can have it running all the time
without losing memory)
It is also compatible with the chat program "FishBomb" which allows
sounds and pictures as well.
Both are, as far as I know, freeware (I dustribute Zing with source)
and should be available on the normal services (mac.archive.umich.edu
for instance)

Some kind soul told me that I could change the serial port buffer size

Could he or any one else please tell me what to do?
I assume that the relevant resource is zSet, but I do not know, and
I have no template for that resource. If you have a TMPL for the correct
resource, I would be grateful to receive it. That way, I could play around
a bit and maybe get my Duo to do something useful with its serial port.
(other than Appletalk).
BTW, I believe that when the port stats says that maximum in buffer is
3074 bytes, that that means increasing the buffer will help, if you are
using hardware handshaking. I can cram text data pretty fast into my Duo,
and can monitor that CTS is being lowered, but the buffer never gets beyond
3074 (out of 4096) bytes. Makes sense to me.

Disclaimer: This posting may contain no views at all
News-Software: Usenet 3.1
Lines: 45
I have tried almost everything under the sun to get a null modem connection
between a Mac Duo 210 and a PC. I have used MacKermit and VersaTerm on
the Mac side. I have used Procomm, Kermit, and Softerm (on OS/2) on
the PC (or PS) side. I have used non-Hardware handshaking and hardware
ahdshaking cables. And know MY hands are shaking from the effort. Nothing
has allowed file transfers from the Mac to the PS.
In general, I can type back and forth with no trouble, but only if both sides
are set to speeds OVER 9600 baud. I cannot send files from the Mac to the
PS at all, and file transfers from the Duo to the PS are not possible.
When I do a straight ascii send, I can send from the PS to the Duo flawlessly.
I can send Binhex files this way quite fast, and I know that the
transmission is error free.
But straight ascii sent from the Mac to the PS is full of errors.
Unless, of course, I do text pacing so slow that it is like human
typing. (well, like 2-3 times faster than human typing).
I would like to hear from ANYONE who has been able to transfer files
from a Duo 210 to a PS via modem or null modem. If you can do it, please
tell me your EXACT combination of hardware and software. Obviously, I am
talking of a true serial port modem, not the express modem. Maybe some
kind soul with access to a modem and a Duo 210 can check this out for me.
Right now, I am of the opinion that it won't work at high speeds because
of the power interrupts on the Duo, and it won't work at low speeds
because of some crazy reason I don't understand.
Could I hear from someone attesting that they can really pump information
out the serial port of a Duo 210 fast? Like via a modem or via a
sys-ex dump?
Could anyone with a Duo help me out?? I am going absolutely INSANE.
I wanna know if the problem is MY Duo, or all Duo 210s, or all Duos,
or just me.
Yes, I have checked the cable 1,000,000 times. And not only can I type
back and forth, but Zterm alerts the users if s/he uses hardware handshaking
and CTS is down. So I know that hardware handshaking is working. And also,
According to Zterm port stats, the buffer never overflows.
Please help me figure out what's going on...

All I know is that the Megadrives worked perfectly on both my

the problem had something to do with the Quadra.  Even with the
Quadra, they mostly worked OK.  The problem occurred when I ejected

This problem is most likely the same that all cx users are experiencing....
Thanks to one very adventurous USENET reader (sorry I can't remember the
guy's name!  Somebody please post it....he deserves the credit for saving
us all $$$$$) it is easily fixed, if it is the same problem......
Best I can figure it is due to time, heat and repeated warmup/cool downs in
the power supply....i.e., bad solder joints in the power supply circuit
card.  Go get a desolder tool from radio shack, a low wattage iron and some
good nonacid solder and resolder the lower left quadrant of the circuit
card with the AC plugs facing away from you..........or get someone to do
it for you.  It took me less then 10 minutes and saved me at least $300 for
a new supply!

I'm considering buying one of these to offload the internal video
in my IIci and to get 24 bit color capability on my 13" monitor. What's
the deal on them?
1) Do they come with varying amounts of RAM? If so, what is the max
and min? How much do I need for 640 x 480 x 24 bits?
2) What bit depths are supported? One, 2, 4, 8, 16, and 24?
3) Are all these cards accelerated or just some? Is it true that
modern accelerated video cards are (at least in general) faster? What
bit depths are accelerated, all or just 24 bit? I've heard that some
applications actually run *slower* with this card if they write directly
to the screen (or something like that). Is this a frequent problem?
How much slower is it?
4) Didn't I read (when System 7 first came out) that the card was
incompatible? If so, how was this corrected (Finder patch, some INIT,
or other)? Has it been kept compatible with 7.1? Are there many other
apps that it is incompatible with (games or important (i.e., non-
Microsloth) apps, for example)?
5) If you have a strong opinion on it's value for someone in my position,
let me know what you think a reasonable price is to pay for it.
Thanks a lot for you input.

The Quadralink by AE is a possibly problematical solution to your needs.
I've used one for the last 4 (?) years on my personal system, but a fatal
bug has crept into their more recent s/w. The bug only shows up during
heavy serial traffic but completely crashes the system (MacsBug can not
reboot, time to hit the restart button).
AE told me in January that they were aware of and working on fixing the bug
which I described to them. Since then they have not answered any of my
faxes asking them for a status of the bug-fix.
The QL has been great, but for now I have mine sidelined. If you are only
going to be using 2400 Baud or less, then you may have no, or very
infrequent problems,

To display Millions of colors on a 16" monitor you need 2MB of VRAM
in the Q950.

Correct. This is the amount of on-board VRAM that the Q800 comes
with.

Yes this is possible. Technically, you only need to take out 2 of
the VRAM SIMMs but leaving in the other two will not get you anything
because the 950 cannot really do anything with 1.5MB of VRAM. It only
knows 1MB and 2MB.
>From the documentation I have, the Quadra 800 must get 1 Mo VRAM to have

Yes, this is correct. You get to 1MB by putting 2 256k VRAM SIMMs
into the VRAM SIMM slots on the Q800's motherboard.

Yup. You have to take off the power supply. It's only a couple of

disconnected from it and watch out for static discharges.

Or at least a passe_through connector so i can keep my graphic card.
I need your advice about the best card i can buy. How much performance

I have an Ethernet card for the LC with fpu. I don't think it would
work for the IIsi but the fpu is socketed. Do you think i can take the

If you mean in a "newer, more powerful" Mac system then the answer

I think this is mostly the fault of the people who write up the
literature and price lists being confused themselves. Since there are
two possible processor configurations and one of the them doesn't have
an FPU it does seem to be an option, even though it really isn't.

Well, then allow me to end your confusion. The C650 ONLY come with
an LC040 in the base 4/80 configuration. If you are not getting this
configuration then you are getting an FPU.
>>Why say "optional" if it's built in?
Good question. I have been wondering that since Feb. 10th.

This is possible, but an option is something that you are supposed
to be able to request when you want it. What Apple has done is given the
buyer a CHOICE between configurations and not an OPTION.
>Apple does not offer an upgrade from the non-FPU system to become an FPU
>system.  And, it is unclear whether the '040 processor on the non-FPU system

This is not unclear at all. In fact Apple has included in the ROMs
of those machines with LC040s code to recognize the presence of the full
040's FPU and use it. Thereby making the upgrade as easy as switching
chips. You pop the LC040 out and pop in a full '040.

They did? I think I would double-check this. It has been stated
countless times in this newsgroup by two of the Centris hardware
designers that the LC040 and the full '040 are pin compatible and that
the C610 can be upgraded to a full '040.

Apple has really confused people with this whole thing. I think
we'll be answering this question for about the next year or so. There is
no "option" to get an FPU on a C650. What you have is a choice of CPUs:
there is the 68LC040 that does not have an integrated FPU like the full
'040 and is only present in the base 4/80 model of the C650 (AppleUSA).
And there is the full '040 which you get when you order anything other
than the base 4/80 configuration. Therefore, since you have ordered one
of the 8MB versions with on-board Ethernet models you will not be
getting the LC040. But even if you wanted to have the LC040 you wouldn't
be able to order a C650 with 8MB RAM, on-board Ethernet and an LC040.
It's not an "option."
Also, a note to people out there that have 4/80 C650s and C610s
thinking that there is an optional FPU, the '040 class chip cannot
recognize an external FPU, so there is no socket on the motherboard for
a FPU chip and you cannot go out and purchase an FPU on a PDS card or
something like that. The only way to get an FPU in these machines is to
replace the LC040 with a full '040. And if you have a C610, you will not
need to worry about a heat sink if you do replace the LC040 with the
full '040, but if you have a 4/80 C650 you do need to have a heat sink.

What you need is a hardware router such as EtherRoute/TCP made by
Compatable Systems ($1400).  This will allow you to connect your Localtalk
network (4 Macs) to your Ethernet network (NeXT and Ethernet Mac).  It will
route TCP/IP protocol between the two networks.  Software routers are also
available for less money, but I'm not sure if they work with TCP/IP.

Hi.  I am working on a project for my marketing class and I'd like to
ask your help.  The assignment is to come up with a product and create a
marketing plan for it.  Technical issues are not terribly important at
this point.  Well, my group's plan is to market a "full page" monitor
for laptop computers.  It would be a third-party product to be installed
by authorized repair centers (like Newer Technology's PaletteBook
screen).  The idea is that the screen would fold in such a way that you
would get twice the screen height of a normal screen (remember,
technical issues aside!).  In fact, by adjusting the fold of the screen
and the monitor configuration, you could have regular OR "full" height.
The screen would probably be monochrome.
The motivation behind this is that laptop computers seem to be very
popular among business people.  Business people also commonly use word
processing and spreadsheet applications for which it is very convenient
to see a large portion of the document.  Because of the target users and
applications, color screens aren't really a neccessity.  We could
hopefully keep the cost between $2000 and $3000.
Now, please don't write this off as completely ridiculous.  I really
need some constructive feedback.  So, if you would, please reply to me
via email and let me know:
1. If you would consider buying a "full page" laptop screen
2. How much you would be willing to pay for it
3. Any helpful commentaries on the idea
Also, if you take this idea and make a lot of money off it (doubtful,
but who knows!), please send me some.
Thanks in advance!!!

Dear Mac-friends,
I've seen the following problem om three Mac IIsi machines
all with 17 Mb RAM installed (70 or 80 ns SIMMs).
If the contents of a window are being calculated and updated
a lot of strange horizontal lines are temporarily generated
on the screen.  The lines translate to the top of the screen and
have a slightly lower brightness than their surroundings (they
are a few millimeters apart).
I admit that they are vague, but they can still be distinguished clearly,
especially if the environment (i.e. the rest of the room) is a bit dark.
Applications which produce this effect are:
- the previewer of DirectTeX 1.2 (i.e. DVIReader 1.2)
- Kaleidagraph 2.1.1/FPU
The machines use their built-in video and drive the old
Apple Hires Monochrome screen (two monitors/cable sets tried).
The effect is independent of the settings in the following control
panels: Memory (adressing mode, disk cache)
and Monitors (nr of greys/colors).
Have you ever seen this effect too ?   Is there a solution ?

The problem mentioned last is a known Quadra SCSI problem, it was heavily
discussed last year and an Apple employee pointed out that there was a
one byte error in the SCSI driver routine for the Quadra's (at least the
700
and 900).  System 7.1 should not have that problem, for most people the
solution was to get an updated driver from the drive manufactor.  In my
case MASS Microsystems wrote a new driver which fixed the problem on my
Quadra
700, all that occured early last year.

NuBus is a much more robust system for system for installing multiple
cards without configuration problems.  I know that when I was checking
into expasion options for an SI there were a number of PDS video cards
that would not work with certian Dual slot cache adapters.

Hi!
A while back, there was a thread in this group about the use of the IWII
in Europe (in countries with 50 Hz AC current).  The consensus at the time
was that the IWII would not work there.  As I will be moving there this summer,
I called Apple to make sure and they told me (today) that the IWII (as bought
in the U.S.) will definitely run on 50 Hz AC current (as long as a step-down
converter is employed if 240 V current is used).  The same info, turns out, can
be found in the IWII manual (p. 127 in the 1989 version), but I didn't really
trust that.  Does anyone have any direct experience to the contrary?  Just
wondering.

However, if I want to use a larger window, what are my options?
Perhaps I misunderstood the Video Spigot review...
Also, I am not interested in Quicktime.  I would merely like to
use my Mac as a television from time to time.  I have a nice
Sony 1430 monitor, and I would like to use it as a second TV

I've got two CD300's... The first one i ordered Jan 15, and I received it Feb. 20.
The second one I ordered Jan 20th, and I just got it April 2nd or so. Anyway, they
both come with 10 misc. CDROMs... Things like a "Intro to Nautilis", a sample CD
of Kodak pictures, "From Alice to Ocean" (a story of a woman who treked across
Austrailia), 3 discs from apple, a games disc, an applications disc, and a "titles"
disc (haven't checked most of these out yet). Also some "Cinderella" thing for kids,
a disc of Mozart something-or-others, etc. etc. etc. If someone's super interested,
I'll make a list of the exact titles and post them. They are all in the category of
"Interesting, but probably fairly useless...". It was rumored that the earliest
units shipped with SOME encyclocpedia (it may have), but neither of my drives had

I have an SE/30 with a 80 meg HD which dates back to April 1989.  When I
originally purchased it, I experienced the failure to boot problem.  This
was fixed soon after by a ROM upgrade on the hard drive.
Lately a similar problem has been occuring.  When the computer is
powered on the HD light flashes a few times and then I am given
the "no disk to boot from" icon.  However, upon turing the
computer off and on again the drive ALWAYS boots up just fine.
Furthermore, if instead of turning the power on and off I press the reboot
button the same problem occurs.  But, as I said, turning the power
off and on always works.
This problem is different from the 1989 boot problem in that before
it often required several power off and ons to get it to boot.
Does anybody have any suggestions as to what the problem is or how
it can be fixed?
I'm wondering if it's getting old and requires more time to
"come up to speed" now.  Is there a PRAM or SCSI setting that
allows me to tell the computer to wait a little longer before
trying to access the HD?
Thanks!

I'm in the market for a laser printer. Used printers are fine, non-apple
printers are fine, but whatever printer I get must fit the following:
Required features:
- PostScript
- 300 dpi
- emough memory to download fonts
- The cheaper, the better.  I'd prefer under $1000.
Nice things:
- anything over 4 pages per minute
- scsi output for a font disk
- smallish footprint
Don't Care About:
- PostScript Level II
- networking (its just for me, and always will be)
- color
I know about Freedom of Press, but I've also heard that its painfully slow.
I can tolerate about 4 ppm, but anything slower than that and I'm not going
to consider the price savings worth it.  I'd be curious to hear people's
experience with it, tho.
I also infinitely prefer laser over ink; I used to use HP deskjets in
my last job and wasn't impressed with the quality.  I'm a laser bigot
and the first to admit it. :)
I'll be using the printer to layout pages of a book I'm writing.  The
page will include multiple fonts, PS graphics, scanned line art and
maybe greyscale pictures (not sure yet).  The quality doesn't need to
be spectacular, but it needs to be clear and readable.
Printers I've been looking at:
- used LaserWriters: The plus, the NT, the NTR.  Its my understanding that
only the NTR has a SCSI out for a disk. True?
- Personal LaserWriter (LS and NTR).  I have access to the Apple Employee
discount (I work for one of Apple's spinoffs), so I can get these reasonably
cheaply.  I've heard bad things about the LS; comments?  I'm leaning
towards the Personal NTR, cause it has a nice small footprint.
- LaserWriter Select 300.  I hear it doesn't have PostScript, but I haven't
seen anything for sure.  I heard mumbles once about a "postscript upgrade."
??
- Used HP LaserJets.  I've worked with the II and IIP on another platform, and
they were *painfully* slow.  Are they that bad on the mac?
- I've seen ads for an Epson PS laserprinter that is running quite cheap.
Any comments on this printer?  I hate the styling (too many ouput trays),
but if its a decent printer I'll consider it.
Thanks for any comments...

Okay, I guess its time for a quick explanation of Mac sound.
The original documentation for the sound hardware (IM-3) documents how to
make sound by directly accessing hardware.  Basically, you jam values
into all the even bytes from SoundBase to SoundBase+0x170. This was
because
of how the Mac 128 (and some later machines) generated sound was by
scanning
this block and D/Aing every even byte (the odd bytes went to the floppy on
some machines).
When the Mac II (and Apple Sound Chip) was invented, it was designed to
generate stereo sound. It was also designed to be compatible with we had
once
documented. So storing bytes at the even values at SoundBase meant "I
want to
play a mono sound" and so it was emulated. But Apple had since retracted
the
documentation on SoundBase and decided not to document the lowest layers
of
sound generation. So apple never explained where to stuff bytes if you
want
to make stereo sound.
Enter game developers. The sound driver and current sound manager are
inconveniently lame for making games. Furthermore, people who port from
the
IBM don't want to learn more APIs. So, it has become popular for game
writers to write to SoundBase to make sound, since it is very easy.
Since the Mac II, Apple has had many different kind of sound output
hardware,
and the only things they have in common are that writing to SoundBase
works.
On some hardware, (Mac II, IIx, IIcx, IIci at least), writing to SoundBase
gets you mono sound through both speakers. On some Macs (Quadra
700/900/950
at least) writing to SoundBase gets you mono sound on the left channel
only.
Both are technically correct interpretations of the original
specification,
but one is obviously preferable for asthetic reasons.
If developers use the Sound Manager (and I think the sound driver), mono
sounds will (typically) come out through both channels regardless of the
underlying hardware. It is possible to specify you want to generate left
channel only, but no one does. If developers write to sound base, their
games will only come out the left on some games.
The other problem, the original Mac II only producing left channel sound
on the internal speaker, while the SE/30 mixes both, isn't really related.
It is due to the post generation amplification used on the motherboards of
the different machines. It only affects true stereo sounds. Sounds which
are actually mono, will play on the internal speaker, no matter what
machine
you have.
Now, to more directly address the question, the games you list:
>Lemmings
>Out of This World  (awesome game, BTW)
>Glider 4.0
>OIDS
and also
Hellcats,
Super Tetris
Oxyd
(and many more, these are just what I've tested)
Cheat and write to SoundBase and so are only left channel on Quadras.
Other games you list:
>Armor Alley
>Spectre
>Spaceward Ho!
and also
PGA Tour Golf
Civilization
(and more, these are again only from personal experience)
Use the sound manager and work fine on all machines.
The more of the story is to developers: DON'T CHEAT!
Really, I am absolutely, positively not allowed to do what I am about to
do,
but I'm going say it anyway.
Stop cheating on sound!
Really soon, you will be sorry, as even those without external speakers
will be disappointed with your sound on future hardware. The grace period
is about to end.
The Sound Manager is understandable now, and works pretty well and will
work
even better soon, so use it.
In conclusion:
To Doug, it isn't a hardware problem, at least, not a bug.
To Jon, it isn't a choice to developers as to whether they want to send
sound
to both channels. If they do it the right way, it is taken care of
automatically. If you cheat, there is not way to make it work on all
hardware.
Have fun.
Disclaimer number 1:
I don't work on sound here at Apple, I'm just pretty well informed.
So don't write me with sound questions.
Disclaimer number 2:
If it says up above that I wrote anything like "the grace period is about
to end" then it is a bug in your news feed, since I am catagorically not

While there may not be a part number for the CD300i drive, I have seen
a part number for the bezel kit (a new front panel with the slot in it
through which you insert the CD). The document (which I got from the
2/10/93 announcement at our Apple office) states the drive kit and bezel
kits are separate items and the bezel kit has an SRP of $149 fro the C650.
The external unit may be a better deal after all.

The problem is this:
After starting up my machine it gives a high pitched sound once at the desktop also it only does it when the mouse is up or a menu is not showing.
as if I click the mouse the noise goes away for the amount of time the mouse is down. also this problem only happens for about 5-10 minutes.

The original poster (W G Wright) posted an item saying that he had bought a new
wizz-bang Laser Printer from Apple (a Select 300 I think) which can print
GrayScale. He then said that he CANNOT PRINT GRAYSCALE from his SE computer
(and also that all the 'experts' he has dealt with agree that it is not
possible).
This is the one major bugbear about doing a 3rd party SE upgrade (compared to
Apple's SE to SE/30 upgrade): you will never be able to run Color Quickdraw. It
is Color Quickdraw that controls Color AND Grayscale.
SEs CAN print some COLOUR: this is because Quickdraw - the original, non-colour
version, has the right hooks for eight colours. Some of you will remember the
'SCSIgraph' solution to getting a colour screen for your SE (I think that it
gave you sixteen colours by dithering or something).
There is no reason that Apple couldn't release software patches for older
computers (there are lots of Mac Pluses, Classics and SEs that have been
upgraded to 68020 and 68030 processors which should be perfectly able to deal
with Color Quickdraw) - but they wont, and 3rd parties are having a difficult
time in duplicating the Mac's ROMs (i.e. Nutek et al.).
Just one Caveat: I would have thought that if you were printing a POSTSCRIPT
Grayscale image onto a POSTSCRIPT Grayscale printer, that you would be able to
do so, whatever Mac you were using. (And I am pretty sure that the Select 300
is NOT a POSTSCRIPT printer [? correct me if I'm wrong?]).

Try looking at the Brainstorm Accelerator for the Plus.  I believe it is
the best solution because of the performance and price.  Why spend $800
upgrading a computer that is only worth $300 ????
The brainstorm accelerator is around $225.  It speeds up the internal
clock speed to 16MHz.  That may not seem like much but it also speeds up
SCSI transfers.  I think that feature is unique to brainstorm.
Check it out.

Just a quick summary of recent findings re. high speed modems. Top three
contenders seem to be AT&T Paradyne, ZyXEL, and US Robotics. ZyXEL has the
biggest "cult following", and can be had for under $300, but I ignored it
because I need something with Mac software, which will work without any
tweaking.
The AT&T Dataport earns nearly unanimous praises for reliability. They are
backordered at the moment, probably because of the special $299 price in
effect until May. Its fax capabilities are worse than that of the other two
modems. WARNING: AT&T ads say that the modem comes with a Mac kit (cables &
all), and has lifetime warranty. This applies *only* when you order
directly from Paradyne! I called ElekTek (one of the distributors), and
they wanted to charge me $16 for cable, and gave only 1 year warranty...
USR Sportster for the Mac is also highly (but not as highly) recommended;
it's only $250 from ClubMac, and if you are willing to roll your own cable
and don't care about the FAXstf software, you can get the generic model
from PC outlets for $190.
All this assuming that you don't have a rich uncle, and can't afford a
Motorola Codex...  :-(    I ended up ordering the Dataport; we'll see how
it works in two weeks or so.

I think you are suffering from some alignment or color
table or <whatever> problems, if a Color Classic is as fast
as a Quadra rendering to screen.
What screen card you use does of course matter much (built-in
video is almost always faster than NuBus)
Or you measured "scroll entire screen" where the Color Classic
had a VRAM 10" screen in 4-bit color and the Quadra had a
21" 24-bit screen on NuBus :-)

Jeff,
I have answers to both of your questions.  First, I recommend the Sony
CPD-1320 monitor.  It is a 14" Trinitron VGA monitor, but it is designed
specifically for use with the LC.  It works only with Macs with specific video
capabilities which means only the LC's and anything after the ci.  All it
takes is a MAC<->VGA cable (I recommend one from James Engineering which is
about $20).  These cost about $335 as compared to the much higher prices of
comparable monitors because they are not multisynch.  I have used one for half
a year and I love it.
Second, I have used Syex and found them to be decent.  I had a backorder on a
Supra modem which I cancelled.  They were helpful in explaining the reasons
why there were delays and they had Supra's number ready for me.  The only
complaint was that they did not always return my calls.
I have been told that the CPD-1320 is selling for $339 from J&R's
(800)221-8180.  I think Syex is a little more, but I don't know.

Lines: 26
The subject says what I would like to do, here are the details:
I have a 512ke with the MacRescue upgrade board that makes it the
equivalent of a Plus (System 7 and MacEnvy both identify it as such).
The MacRescue board clips onto the 68000 on the MB.  It also has
a 68000 itself.  Periodically I have to remove the clip (not an
entirely easy thing to do) and clean the "legs" of the 68000.
Larry Pina's book asserts that this is occasionally a problem with
snap on upgrades:  the 68000's "legs" will oxidize, causing
unusual system errors.
Well, that's me.
So, I would like to do something permanent, and I think it would be
fairly easy to put a socket in where the 68000 currently is, and
modify the MacRescue board to plug in.  What I'm not 100% sure of
is whether it will work.  It seems to me that the two 68000s aren't
acting independently; so removing one shouldn't have any effect on
the performance of my Mac.  I'm about 97% sure.
Will someone provide the extra 3%?

The Quadra 700 goes thru extensive initalize routines of its hardware,
read's PRAM, obtains all info from last session including the volume
setting, and then executes the sound procedure for the startup sound, and
wait's on the SCSI controller to respond to the boot up code.
If the DRAM produces an error, or a registers cannot be read from a device,
or the device corrupts that address/data or control paths, then if it is
possible, the firmware branchs to another sound routine that produces the
'sad mac' sound.
This is a general breifing of the start up procedure of a typical mac.
If you cannot control the volume of the quadra, even at boot up, then i feel
there is something incorrect with the logic board.

I want to go from 512K to 1M VRAM on my Quadra 800.  How many 512K SIMMS do I
need to buy?  Is the current 512K soldered on the board or do I need to take
out the current VRAM before I add more?
Thanks,

well folks, my mac plus finally gave up the ghost this weekend after
starting life as a 512k way back in 1985.  sooo, i'm in the market for a
new machine a bit sooner than i intended to be...
i'm looking into picking up a powerbook 160 or maybe 180 and have a bunch
of questions that (hopefully) somebody can answer:
* does anybody know any dirt on when the next round of powerbook
introductions are expected?  i'd heard the 185c was supposed to make an
appearence "this summer" but haven't heard anymore on it - and since i
don't have access to macleak, i was wondering if anybody out there had
more info...
* has anybody heard rumors about price drops to the powerbook line like the
ones the duo's just went through recently?
* what's the impression of the display on the 180?  i could probably swing
a 180 if i got the 80Mb disk rather than the 120, but i don't really have
a feel for how much "better" the display is (yea, it looks great in the
store, but is that all "wow" or is it really that good?).  could i solicit
some opinions of people who use the 160 and 180 day-to-day on if its worth
taking the disk size and money hit to get the active display?  (i realize
this is a real subjective question, but i've only played around with the
machines in a computer store breifly and figured the opinions of somebody
who actually uses the machine daily might prove helpful).
* how well does hellcats perform?  ;)
thanks a bunch in advance for any info - if you could email, i'll post a
summary (news reading time is at a premium with finals just around the
corner... :( )

I have been using the PLI (SONY) 3.5" MO drive and now a Sharp color
scanner using standard SCSI cables and STANDARD $20 terminator on my Q700.
No problems.  If you were using a IIfx, that might be another story.
Make sure there is only one terminator in the cabling and it must be at the
end.  Some boxes have internal terminators; some can be switched out and
others are socketted.  These count.  If the box with internal terminations
cannot be put on the end to terminate the cabling, they have to be
disabled, ie, switched out or pulled out of their sockets.  If you have 2
boxes with internal terminations, the terminations in one box has to be
disabled...., etc.  I am sure that this has been covered by the "experts".
My experience with SCSI boxes that connect to the Mac indicates that they
must have some software package for the Mac to 'talk' to them.  My PLI MO
drive and Sharp scanner has one for each.
Good luck.

1)    I have an old Jasmine drive which I cannot use with my new system.
My understanding is that I have to upsate the driver with a more modern
one in order to gain compatability with system 7.0.1.  does anyone know
of an inexpensive program to do this?  ( I have seen formatters for <$20

Question for those familiar with Quadra VRAM:
I put 2 256K VRAM SIMMs in my Quadra 700 (in the 2 slots closest to the
RAM SIMM slots) and I got no results whatsoever.  I have been told that
the built-in video should support at least 16bit and maybe 24bit color on
a Macintosh Color Display.  However, the Monitors control panel still
lists 8bit (256 colors) as the highest possible.
Does it make any difference which slots you put the SIMMs in?
Do you have to do something to activate them?
Do you have to do something to the Monitors control panel?
BTW, I am running System 7.1 with 8 Megs of RAM.

Yes, E-Machines makes two mini-docks--the Powerlink Presente and the
PowerLink DeskNet. The Presenter offers a variety of video-out options,
including NTSC, RGB and SVGA. It also has sound out, floppy drive port
and a power port. Unfortunately no SCSI port and it blocks the serial port.
The DeskNet has the standard ports plus built-in EtherNet. Alas, none of
these have an FPU.
In the future, RasterOps is putting out a mini-dock, but the name escapes
me now. It is supposed to support 16-bit color and "Quadra" comparable
video speed. No idea if it has an FPU.
Hope this helps...

I think you must be talking about the Syquest 105 (code named Mesa I believe).
It is a 3.5" Winchester technology drive pretty much like the other Syquest
drives in terms of how it works. According to the latest MacLeak, the
drive has a 14.5 ms access time, 1.9 MB/s sustained throughput (these figures
are from memory so they could be slightly off, but they give you an idea of
performance nonetheless). The drive was originally released for the PC
and just recently was released for the Mac world (don't ask me what the
differences are) and through they are currently in limited supply, according
to a Syquest rep. they are in the process of ramping up for mass production.
I have already seen them advertised by a number of manufacturers in MacLeak
including PLI, MassMicro, ClubMac, and MacWarehouse's PowerUser. The PLI
and MassMicro units are priced at just around $1000; the lesser name brands
are going for around $750 for an external drive. Cartridges which hold
105 MB sell for about $80 each. At these prices, the drives and cartridges
are cheaper and better performing than the 88MB drives.
Cost per megabyte compares favorably with other cartridge drives and Bernoulli
drives, but for large amounts of data optical is still cheaper, and more
reliable.  Personally, I'm excited by the new drive and look forward to
getting my hands on one.

The CPUs
Note: I am only showing Motorola & Intel CPUs used in Mac and most IBM/PC
clone machines. For example, since Apple never used the Motorola 68008 and
68010 in the Mac these chips are not listed. Years only appear with dead CPUs
and indicate first to last year used as a CPU.
Cache note:  both IBM and Mac use caches external to the CPUs. These external
caches increase the speed of the CPU but are not a part of it.  In most of
the present Macs there are external caches built-in while with IBM they are
optional {Though machines are generally sold with them installed}.  Since
there are many different external caches {CPU-Mac and IBM; SCSI, video, disk
and static RAM-Mac}, each having a different effect on CPU performance, and
they are machine {32KB static RAM cache in IIci, IIfx, and IIvx}, seller
{cache card installed in some IIcis} or expansion {IIci cache cards go up to
128KB} dependent, I have decided to leave them out of the list.

sensitive to the PCLK and so they act as if the 68040 was a clock doubler
chip, but this very compiler and program dependent.  Compliers maybe written
to allow programs to take consitant advantage of the 68040's PCLK in the
future.  As it is now, studies such as one in a Byte article {which showed
040/25 ~486/50 and roughly ~486dx2/50} are very dependent on the machine, OS,
and programs tested and as such are not representative of general performance.

higher frequencies than Motorola, so this evens out.  The Macintosh Bible 4th

lines/data & address registers].  The 4MB limit on the 68000 Macs brings it
down to the 80186 and lower chips, otherwise it would compare to the 80286.}
286        ~ 68020 {hardware segmenting vs. 68020's 32-bit ALU and these chips
come have no usable built-in MMU unlike their successors [80386, 68030].  The
hardware segmenting's protected mode is used by OS/2 1.0 => and Windows 3.X.
The use of the hardware segmenting and their 16-bit nature put the 286 between
the 60000 and 68030 in features and the LC's 16-bit data path strenghthens the
286 ~ 68020 comparison.}
386       ~ 68030 {Two 32-bit chips with MMUs, and protected memory.  A/UX 3.0
is at present the only Mac OS to use the 68030's protected memory feature for
apps.  System 7.x uses this feature to protect a RAM disk created by the
Memory control panel but this is supported only on Powerbooks and Quadras.
The Color Classic and LCII 16-bit hardware data paths makes the 68030s in them
comparative to 386sxs.}
486sx   ~ 68LC040 {same as 486 and 68040 without the FPU; used as a low cost
solution for people who do not need the FPU.  Only with programs sensitive to
PCLK & pipelining does the 68LC040 behave like 486dx2 - FPU or a '486dx2sx'.}
486     ~ 68040 {two 32-bit microprocessors with built-in FPU, MMU, 8K
internal cache (which is implemented as two 4K caches in the 68040 and one in
the 486).  Only with programs sensitive to PCLK & pipelining does the 68040
behave like a 486dx2.}
Pentium   ~ 68060 {Both are planned to be superscalar but both have heat
problems.  These chips may flounder against the cheaper (PC Week 3/08/93;
4/12/93; PC Mag 4/27/93:110), earlier released (PC Week 12/7/92; MacWeek
12/14/92; PC Week 2/08/93), less leat producing {160 degrees F for Pentium
(PC Mag 4/27/93:118)}, and partly ported to PowerPC chips.}
PowerPC   = PowerPC {This CPU line is planned to run programs from DOS,
Windows 3.x, OS/2 and Mac OS on top of PowerOpen-A/UX 4.0 [UNIX] and later
Pink [Taligent OS] by using emulators or, if necessary, the OSes themselves in
a 'shell' a.k. how SoftPC or OS/2 does DOS.}
Hardware
{In an effort to remove the 'reconfiguring the system almost every time you
add something' requirement for add-in cards, drivers, video, and operating
systems in the IBM world, Intel, Microsoft and 12 other hardware and software
developers are working out 'plug and play' standards (PC Week 03/08/93).}
Color Support/Display
Mac: 30.24 MHz Pixel Clock standard.  All present Macs support the use of
32-bit color through 32-bit color QuickDraw in ROM.  32-bit color QuickDraw
allows an almost transparent capability to display and edit X-bit images in Y-
bit color and retain ALL the colors of Y-bit color [Where X and Y
independently are 1, 2, 4, 8, 16, or 32] regardless of monitor resolution {63
dpi [12" color] to 94 dpi [PaletteBook]} or monitor type {including
autosynchronous VGA, MCGA and SVGA monitors with ranges including 66.7 hz
vertically and 35 kHz horizontally and only a hardware video adaptor (MacUser
Aug 1992: 158-176).  Older machines that supported color {SE/30, II, IIX, and
IIcx} had only 8-bit color in ROM and needed a software patch to use 32-bit
color (MacUser Special 1993:28-29).
To keep costs down and speed up most Macs have only 8 or 16 bit display
capability built-in, but most of those can be expanded to display 24-bit
color.    Presently QuickDraw is optimized for 72 dpi display; QuickDraw QX
will change this.
In addition, QuickDraw allows, in Macs with a NuBus slot, more then one
monitor to be used in any combination, from two monitors showing the same
thing to multiple monitors acting as one large large monitor with any degree
of overlap of the pictures.
VRAM: Video RAM.  Standard for present non-PowerBook Mac's handling of
built-in video {from a 32-bit color palette}. VRAM provided runs a 8-bit
color 640x480 display; expandable to 16-bit color or a 8-bit 832x624 display.
Sound output:  Standard in all Macs since the 128K.  Stereo sound became
standard with the SE/30.
IBM:  Even though PCs have ROM BIOS definitions of how the operating system
interacts with the video hardware (Nan Zou), the use of drivers bypassing
BIOS, video hareware inconsitancies {see Super VGA below} and nonstanderzation
of clone BIOS have left resolution of video display hardware, OS and program
interaction up to the OS and video hardware in question (Faisal Nameer
Jawdat). In addition, IBM and clone makers never bothered to provide a
standard hardware mechanism for software to determine what display mode is
actually present (Matt Healy) nor a standardized screen-drawing toolbox {like
Mac's QD}. As a result the OS must be very well written to detect some modes,
especially with some third party cards or to use them consitantly {At present
things are so dependent on the interaction of the program, OS, print driver
and monitor card that editing 32-bit pictures regardless of color mode, OS,
and monitor type/card combination as one can do on the Mac is impossible with
an IBM.  For example, one cannot edit a 32-bit color picture done on a OS/2
486 with a SVGA monitor on a 386 with VGA {18-bit color palette} and DOS 5.0
and still have ALL the colors one started out with}.
Later IBM machines will have integrated graphics accelerators, faster
processors, and modular upgradeability and may have built-in sound cards, CD
ROM, and Ethernet (PC Week 12/14/92).
MDA: Monocrome Display Adapter
original character-mapped video mode, no graphics, 80x25 text.
CGA: Color Graphics Array
320x200 4 colors or 640x200 b/w, 16 color palette, bad for the eyes.
EGA:  Enhanced Graphics Array
640x350 16 colors from 64 color palette [and some lower res]; some versions
could run at 256 colors, bearable on the eyes.
VGA:  Video Graphics Array*
320x200 at 256 colors, 640x480 at 16 colors, and some others, these two are
the most commonly used.  All modes have a 256K CLUT, from a
18 to 24-bit {IBM} or a 32-bit {Mac} color palette.  25.175 MHz Pixel Clock
(Mel Martinez).  Monitors use analog input, incompatible with TTL signals
from EGA/CGA etc.
MCGA:  Multi-Color Graphics Array*
subset of VGA that provides all the features of MDA & CGA, but lacks some EGA
and VGA modes, like VGA 640x480x16 (Dictionary of Computer Terms-DCT).
Common on the initial PS/1 implementation from IBM and some PS/2 Models.
SVGA:  Super VGA*
This is not a standard in the way the others were, but instead was a 'catch
all' category for a group of video cards.  As such, with each manufacturer
using their own implementation scheme, SVGA was chaos with people debating
as to what is SVGA and what is not.  In an effort to make SVGA more of a
standard VESA was established and is used in the newer units, but things
are still a mess.  Video is either 512K [~1990] or 1M [today], resolution
of 800x600 and 1024x768 at 16 and 256 colors are common, newer ones [since
1990] have the Sierra HiColor RAMDAC, giving 15-bit 32,768 colors at 800x600,
some of the very newer ones [~6/92] can do 24 bits per pixel [usually
at 640x480].  Speedwise, too much variation, some very slow [Western Digital
Paradise based, for example], some very fast [S3 86C911 based, for example],
some are so-so [like Tseng ET4000, a very popular chipset].  Some limiting
factors overcome by 40MHz VL Bus & 386's linear address mapping were:
8.33 MHz ISA bus, AT architecture where the CPU looks at the card through a
64K "window", etc.
Other non-SVGA standards:
8514/a:
IBM's own standard, interlacing graphics accelerator with graphics functions
like linedraw, polygon fill, etc. in hardware. Some clone implementations
from ATI are the fastest video available today, though some clone models do
not have interlacing.
TMS34010/34020: high end graphics co-processors, usually >$1000, some
do 24-bit, speeds up vector-oriented graphics like CAD.
XGA:  eXtended Graphics Array
newer and faster than 8514/a, only available for MCA bus-based PS/2s, clones
are coming out soon.  Emulates VGA, EGA, and CGA (DCT).  Max resolution at
1024x768x8b, same as 8514/a, also some 16 bpp modes.
XGA-2
Accelerates graphics functions up to 20 times faster than standard VGA in
Windows and OS/2, including line draws, bit and pixel-block transfers, area
fills, masking and X/Y addressing. Has an intelligent way to detect and co-
exist with other XGA-2 cards, so multiple desktops like on the Mac may not be
far away.  Since this is an architecture, its resolution and color depth
isn't fixed {IBM implements only 16-bit [65,536] color, while other
companies can have 24-bit color through IBM technical licenses}. Refresh
rates up to 75 Hz, ensures flicker free, rock solid images to reduce visual
discomfort, and is VGA compatible. Up to 1280x1024 on OS/2.
*some monitor types usable by Mac-See Mac section above for specific details.
Expansion
Both Mac & IBM
SCSI: only external device expansion interface common to both Mac and IBM.
Allows the use of any device: hard drive, printer, scanner, Nubus card
expansion {Mac Plus only}, some monitors, and CD-ROM.
Main problem:  there are a lot of external devices which are internal
terminated which causes problems for more then two devises off the SCSI port
{A SCSI chain is supposed to be terminated ONLY at the begining and at the
end.  Any other set up causes problems for either Mac or IBM}.
SCSI-1:  7 devices per SCSI controller.  8-bit asynchronous {~1.5MB/s ave}
and synchronous {5MB/s max} transfers.  Difference is due to SCSI-1 software
drivers.  "Fast SCSI-1" is a misname for 8-bit SCSI-2 in SCSI-1 mode
{see SCSI-2 for details}.
SCSI-2: 10 devices per SCSI controller in SCSI-2 mode.  SCSI-2 is fully
SCSI-1 compliant and 8-bit SCSI-2 tends to be implemented as a very fast
SCSI-1 since it does not require the different controller interfaces in
hardware and software that 16 and 32-bit SCSI-2 do.  Transfer speeds are
4-6MB/s with 10MB/s burst {8-bit}, 8-12MB/s with 20MB/s burst {16-bit}, and
15-20MB/s with 40MB/s burst {32-bit/wide and fast}.  Since 8-bit SCSI-2 can
use SCSI-1 software drivers and hardware at 8-bit SCSI-2 speeds and as such
is limited to 7 devices sometimes it is mistakenly called "fast SCSI-1".
16-bit fast SCSI-2 requires a SCSI-2 software driver and SCSI-2 electronics
but can still use the SCSI-1 ports.  Wide 16-bit and 32-bit SCSI-2 require a
different SCSI port, electronics, and software driver from SCSI-1 {Which
makes them more expensive than other SCSI interfaces}.
Mac SCSI: asynchronous SCSI-1 built-in standard since the Plus.  Even though
Apple developed some specifications for SCSI controlers, the OS SCSI Manager
needs to be rewritten to take full advantage of the features of both SCSI
interfaces.  As a result present SCSI-2 Macs use 8-bit SCSI-2 as a fast
asynchronous SCSI-1.  Presently Quadras are the only Macs with a SCSI-2
controller chip built-in (Digital Review, Oct 21, 1991 v8 n33 p8(1))
though they lack some other parts of the hardware, like the wide SCSI-2 port
interface.  Since other Macs require a NuBus card to use SCSI-2, older NuBus
Macs had a bottleneck due to the speed of the NuBus and CPU.  Rumor-some
Cyclone Macs {June} will come with a wide & fast SCSI-2 port standard
and have a rewritten OS SCSI manager.
IBM SCSI:  SCSI-1 is not too wide spread yet, generally not bundled with
systems, except as add-on {EISA and VESA Local Bus adapters avalable}.
Like the Mac, 8-bit SCSI-2 is used as a very fast SCSI-1 by most controllers
out there.  Unlike the Mac, IBM has no exact SCSI controller specifications
which results in added incompatibilities for SCSI.
Mac
Memory expansion: with a few exceptions the Mac has used non-parity 30-pin
8-bit SIMM memory expansion since the Plus.  While 32-pin 9-bit parity SIMMs
could be used in these Macs, only special IIcis could make use of the parity
feature {By convension both SIMM types are called 32-pin SIMMs}.  The IIfx
used 64-pin parity SIMMs.  The LC III, C610/650 and Q800 all use a new
72-pin SIMM that is accessable by 32-bits at a time and is used in IBMs.
The Mac does a complete memory check at startup by writing/reading every
memory location; if something is seriously wrong with a SIMM the Mac will
not boot and give a sound chord indicating what the problem is.
Since Macs made before Feb 15, 1993 managed memory baced on data path, SIMMs
had to be installed in pairs {16-bit} or in sets of 4 {32-bit}.  The Centris
650 and Quadra 800 eliminate this with a new memory management setup that
allows memory to be upgraded one SIMM at a time.  If the SIMMs are the same
size are used then the memory is 'interleaved' across the two SIMMs resulting
in a 10-15% performance boost on RAM access (MacWorld Apr 93: 108-109).
Printers, ADBs, and modems: built-in interfaces standard.
Monitor interface and sound input: built-in on most present macs.
PDS: Available in SE & all present non-Powerbook Macs. 16-bit {SE,
Portable, LC, LC II, Classic line} and 32-bit.  Operates at CPU's MHz.
Maximum through put: data path in bytes*CPU's MHz {Q700/900 & C650:
4 * 25Mhz = 100MB/s; Q800 & Q950: 4 * 33Mhz = 132MB/s}. Standardized with
the LC and 040 bus designs.  With an adapter one NuBus card can be used in
IIsi and C610.  Problem: some cards have timing dependency which slows
through put down.
NuBus Mac II: 32-bit, 10 MHz bus clock, 1-to-1 transaction/bus cycle ratio,
and contiguous, hand-shake transactions at ~10-20MB/s; theoretical peak:
40MB/s.  Built-in on all Modular Macs except the LC series, C610, and
Performa 400.  The SE/30 could be adapted to use this and there was even a
Mac Plus SCSI NuBus.  Supports every possible expansion from CPU to Ethernet
to DMA.
NuBus 90: NuBus Mac II back compatable. 20MHz bus clock, avg throughput:
~30MB/s; burst mode: 80MB/s.  Future card designs will be 7" instead of the
old 12".
QuickRing:  A peer-to-peer bus used in parallel with NuBus 90.  Apple's
VLBus - "Architecture is identical to that of VLBus" (Byte 10/92:128).
Burst mode: 350MB/s (Byte 10/92:128). In development.
CPU expansion: handled either through the PDS or the NuBus.  Unlike PDS,
Nubus CPU cards {example-Radius Rocket} allow use of multiple processors at
the same time.  This is like having two or more Macs in the same box able to
dual task or joinly process depending on the card or software involved {Each
NuBus card needs its own memory but most NuBus cards of this type come with
8MB RAM SIMMs on the card standard}.
IBM
Memory expansion:  parity SIMMs, non-parity SIMMs {some newer models do a Mac-
like SIMM memory check}, or a dozen or so different types of memory boards.
HD Interfaces {limited to hard drives by design or lack of development}:
MFM:  Modified Frequency Modulation, RLL:  Run Length Limited
only used with smaller [� 60mb] hard drives.
IDE:  Integrated Device Electronics
Asynchronous {~5MB/s max} and synchronous {8.3MB/s max} transfer.
currently the most common standard, and is mainly used for medium sized
drives. Can have more than one hard drive.
ESDI:  Enhanced Small Device Interface
~1.25MB/s throughput. generally considered better interface than SCSI-1 in
many ways but not common enough for practical consideration.  Outside of
hard drives, device choices are very limited compared to SCSI-1.
BUS interfaces
{New 'plug and play' ISA and EISA compatable cards may have problems working
with old cards (InfoWorld; PC Week 03/08/93; Vaporware 4/93).}
ISA
8 & 16-bit interfaces common. Has 24-bit data path limit {which produces a
16MB limit for which there are software workarounds} (PC Mag 4/27/93:105).
1.5 MB/s (Byte 3/93:132).  Uses edge-triggered interrupts, can't share them,
hence comes the IRQ conflict.  Limited busmastering capabilities, some cards
aren't bandwidth limited {COM  ports, LPT ports, game ports, MIDI card, etc.}
while others are {video and disk controllers}.  Dominant factor, but it's
showing its age.  Most ISA motherboard designs are 16-bit
(PC World Feb 1993: 144-5)}.
MCA {Micro Channel}
IBM's 16 and 32-bit bus; "allows use of more than one CPU in a computer"
(DCT) and anything can talk to anything, as fast as the two components
involved can handle it. Never took off because it was incompatible with ISA
and EISA.  Planned to be bus interface of IBM PowerPC 601 (Carl Jabido).
EISA {NuBus Mac II is closest Mac equivalent}
32-bit, 8.33 MHz, burst mode: 33MB/s.  It also has the ability to
self-configure cards like MCA and allows multiple bus masters, sharable
interrupt and DMA channels and multiple CPU use.
VESA Local Bus: VLB {Sometimes mistakenly refereed to as PDS}
Local Bus standard. Runs at CPU clock rate,  Burst modes: ~130 MB/s{32-bit}
250 MB/s{64-bit} (Byte 10/92:128).  Limited to three slots but allows bus
mastering and will coexist with either ISA or EISA. Consitered ideal for
video and disk I/O.  DELL has filled a claim that this violates one of
their patents (Mel Martinez).
QuickRing: Apple's faster {350 MB/s burst} version of VLB architecture
(Byte 10/92:132).  Might show up in some IBM and PowerPC machines
(Byte 10/92:132-133). In development.
PCI
Intel's version of Local Bus that is intended to totally replace
ISA/EISA/MCA.  In development.
OSes {assumes full installation [print drivers, fonts, Multifinder, etc.]
and multiple application use.}
Mac
512K to 1MB of OS and hardware commands have been put into ROM.  This allows
Apple to control its machine by putting key hooks for the Mac OS {QuickDraw,
menu commands, print, mouse, SCSI & sound drivers, etc} in ROM, which require
clone makers to use the ROM chip or read ROM on to disks {Which requires
access to the proper Mac since different Macs have slightly different ROM
chips; Plus vs Classic for example.}  With key hooks for the OS support
interface in ROM, programers do not have to worry as much whether the disk OS
has the necessary hardware commands or that those commands are consitant and
therefore can write smaller programs.  This also allows Apple greater control
over hardware-software standards and that the disk OS can be smaller and, with
some of the tookbox command code in ROM, with lower RAM requirements then a
totally disk based OS.  Macs use Masked ROM which is as fast as DRAM (Jon
Wtte).
6.0.7: Single program usage base requirements: 1 MB and DD floppy,
cooperatively-multitasking base requirements: 2MB and HD floppy.
Features a GUI, cooperative-multitasker [MultiFinder], standard program
interface, & standard stereo sound support [snd]. Network receiving part of
AppleShare software is bundled with the OS. Has a 8MB RAM barrier and is a
24-bit OS. Some third party products allow 14MB of Virtual Memory as long as
real RAM is below 8MB.
6.0.8: 6.0.7 with 7.0.0 print drivers.
6.0.8L:  System 6 for some Macs that require System 7.0.X.
7.0.X: Base requirements: 2MB, 40MB Hard Drive, and 68000; De-facto standard
to run all features well: 4MB, 80MB Hard Drive, and 68030 {lowest present
non-portable Mac configuration}.  Using up to 10.08MB {This is EVERYTHING on
system disks} of hard disk space this has 6.0.7 features plus program linking
within and between computers [IAC], built-in server capabilities {Filesharing
can be used by older OSes using AppleShare Client software and can be
accessed by 10 macs max; 4-5 is more speed practical, IAC requires 7.X},
Virtual Memory in machines with MMU{1.6 times real RAM for least noticeable
IIsi speed degradation}, drag and drop, QuickTime & built-in TrueType
support.  Supports sound input [AIFF and snd formats] for most present
machines.  Can access up to 1GB of true RAM and 4GB of virtual memory and is
both a 24 and 32-bit OS.  To use real RAM beyond 8MB it must be in 32-bit
mode and on older machines requires the 'Mode 32' extension.  Apple's last
'free' OS.
7.1.0: 7.0.1 with WorldScript support, speedier, and less RAM usage than
7.0.dot (MacWeek 8/24/92; 9/14/92; PC Week 9/7/92). To run in 32-bit mode
on older machines it requires the 'Mode 32' or '32-Bit Enabler' extension.
Marks the start of Apple saling its Mac OS instead of allowing free upgrades
{Bundled with new machines, $49 for 7.0.X upgrades, $99 otherwise}.
[The installer has a bug that when upgrading it may keep some old system
fonts from the previous system inside the system file.  This can eat up any
RAM benefits and cause other problems.  Apple itself recommends removing all
fonts from the system file.]
A/UX 3.0 [UNIX]: Needs 8MB RAM {12-20MB suggested}, 160MB hard drive, and
a 68030 or 68040 equivalent to run.  This 32-bit preemptive multitasking OS
is large due to being UNIX and needing translators between it and the Mac
ROMs.  Price: $709.
Note: sound output was supported in OSes 3.2 to 6.0.5 by many formats
including the following:  snd, WAVE, ASND, FSSD, QSSN, SMSD, SOUN, dc2d, and
DCFL.  In 6.0.7 the sound manager was optimized for the sound standards 'snd'
and AIFF which causes some playback problems for the old formats, though most
still play.
IBM
Machiness have little GUI code, data, and hooks present in hardware for
programmers to work with, so most of the coding must be provided in the OS.
Since hard disks were slow the disk OS code is read into RAM.  In addition,
what little ROM code there is also read into RAM {a process called Shadow ROM}
This results in faster implementation since RAM is faster then PROMS or
EPROMS.  Having most of the OS code on disk has the advantage of being able to
better optimize the code given a certain piece or collection of hardware which
is harder with a ROM based system due to the 'patches' needed.  In addition it
reduces the need for and size of patches if a major revision of the hardware
support is needed.
Side note:  The FTC charged that MicroSoft formed a OS trust by not providing
all feature documentation for its OSes to developers outside MS and designing
its Windows and DOS apps to fail under OS/2 ("Undocumented Windows") and
"There is deliberate code in [Windows] NT Beta which causes the install to
abort if OS/2 Boot Manager is present" (Gregory Hicks, Info-IBMPC Digest V92
#201).  Due to a conflict of intrest by one member the vote of the FTC
judicial council for action against Microsoft was a tie which resulted in no
action.  Rumors-the FTC will presue the matter, likely to the point of
choosing a new member or whole new council.  In addition the government has
turned down Microsoft's copyright of "Windows" which would allow it to charge
a fee for developers using their hooks (PC Week 03/08/93).
MicroSoft OSes
DOS 5.0: Has a 640K barrier with its own memory manager, a 1 MB barrier
with third party memory managers.  This 16-bit OS requires that each program
must provide its own print drivers and be 16-bit {Programs need to be DOS
Protected Mode Interface (DPMI) compliant and running on a 386dx [32-bit
Protected Mode] to break these barriers}.  Contains the GUI shell present in
DOS 4.0.
DOS 6.0: DOS 5.0 with the added features of a built-in file compresion, disk
defragmenter, debugger for the CONFIG.SYS file. It needs a $80 module for
networking {Cost: $50 through 5/93, after that $129.99}
(Byte April 1993:44-46).
DOS 7.0: 32-bit DOS. In development (PC Week 04/05/93).
Window 3.0: Runs on top of DOS.  Breaks 640K and 1M barriers but still has to
deal with DOS file structure.  Base requirements: 1MB, floppy and 286; to
run well 2MB, hard drive, 386sx and fast display adapter {> 8-bit}.  Has the
equivalent of Mac's QD called Windows GDI [Graphics Device Interface].
This does not have a consistent application interface {Like early Mac
programs  (1984-1985)} nor a very large program base {compared to DOS} and
still tends to slow the machine down (Info-IBMPC Digest V92 #186) with speed
is more dependent on the display adapter then on the CPU (Bill Coleman).
Window programs tend to be disk and memory hogs compared to their DOS
counterparts (Byte April 1993:98-108).
Window 3.1: A faster version of Window 3.0 with better memory managment. Base
requirements 1 MB, hard drive and a 286 ;to run well 2MB, hard drive, 386sx.
Apple plans to release its print drivers for this (PC Week 12/28/92).
Windows for Workgroups:  To run well: 4MB RAM and 386dx (PC World Feb/93:160).
Intermediary between Win 3.1 and Windows NT.  It is basically Windows 3.1
with built-in peer to peer networking support.
Windows NT:  Beta release takes about 50MB of disk space [including the
swap file], and 12MB RAM {Betas are notorious for RAM usage especially in
the interaction between debuging code and program compliers, hence the
reports of 24MB requirements}.  Released version supposed to need 8MB RAM
but, Gates himself now recommends 16MB RAM (PC Week 04/15/92).
This 32-bit OS has Protected mode multitasking, multithreading, symmetric
multiprocessing, a recoverable file system, and 32-bit GDI.  Has built in
networking that is OSF DCE compliant and can handle up to 4GB of RAM.  Even
though some people see a July 4 release date (InfoWorld Nov 16/92), rumor
is that the final version will not be available before Oct 1993
(InfoWorld May 25/92; July 6/92; Vaporware 07/92; 08/92) or 4th quarter 1993
(PC Week 09/28/92). Windows upgrades will be $295, otherwise $495
(PC Week 04/15/92; 03/15/93).
Other OSes
PC-DOS 6.0: IBM's version of DOS 6.0.  It runs Windows much faster then DOS
6.0 due to faster file I/O and video handling (InfoWorld Feb 1, 93).
DR DOS 6.0: same as DOS 5.0 with some extras {like built-in data compression}
and memory management enhancements. Still has 640K/1MB barrier.  A later
version {Novell DOS} of this may use a version of the Mac finder and Apple
file management system (PC Week 12/14/92; InfoWorld Dec 14/92).
OS/2 2.0: Unix like features and unix like requirements; 8-16MB RAM,
60MB {uses 17-33MB} hard drive, and 386dx CPU. This 32-bit multithreaded,
multitasking OS can address up to 4GB of RAM but has to use a fast swap file
to use more than 16 MB RAM on ISA systems using DMA {Direct Memory Access}.
IBM plans to use Taligent's OOPS in future versions of this
(InfoWorld Oct 26/92).
AIX:  IBM's UNIX system, planned to be a subset of PowerOpen and Taligent OS.
NeXTStep: GUI UNIX to provide NeXT features on IBM machines.  Beta out, final
version to be out by May 25, 1993.
Solaris OS for x86: a SunSoft port.  A 32-bit OS with symmetric

Mac 7.1 [working name: Star Trek]:  Apple had System 7.0 running off Intel
Chips and is looking at making a 7.1 version available for IBM
(ComputerWorld Nov 2/92; MacWeek 03/22/93). At present this is planned to run
on top of Novell's DR DOS, require a 486 or equivalent to run and that apps
will need to be recompiled (MacWeek 03/22/93).  Viewed as Novell's answer to
Windows NT.  The complexity of PC hardware set ups is one reason for slow
progress {This seems to Apple/IBM's way of leading to the PowerPC line out in
late 1993/early 1994 and Pink OS in late 1994-early 1995.}
PowerPC
Rumor-IBM will build its PowerPC 601 by late 1993 (InfoWorld June 8 & 15, 92;
MacWeek 7/13/92; PC Week 3/15/93).  It will have MicroChannel bus and XGA
video (Carl B Jabido), and will run native version AIX and Mac apps (PC Week
3/15/93); there have been no comments on compatablity of DOS or Windows apps.
Apple's PowerPC 601 machine {Tesseract} is planned to be out Jan 24, 1994 and
to have MC98601/50 MHz, 4/8MB RAM, a 2.8-Mbyte floppy drive and expected to
sale near LC line prices {~$2000, down from projections of ~$3000 (MacUser
9/92:146)}
(MacWeek 3/22/93).
PowerOpen [A/UX 4.0]: A 32-bit preemtive multitasking OS planned to run on
PowerPCs and 68030/40 Macs (MacWeek 7/13/92).  Intel compatibility uncertain
(See Mac 7.1 above).  Planned base requirements:  68030, 8MB RAM, 80MB hard
drive (MacWeek 4/19/93). Rumor-ahead of schedule; COULD be out by mid 1993.
Rumor-this could be the OS for IBM's PowerPC 601 which is due by late 1993.
Pink [Taligent OS]: Expecting delivery in 1994 (Wall Street Journal 1/12/92)
and may have some parts shipping in OS/2 and AIX in 1993 and Mac OS and
PowerOpen with the PowerPCs (MacWeek 01/25/93).
Windows NT: Possible port (MacWeek 04/05/93).  See IBM OS section for details.
Solaris OS: Version of this Sun Microsystems Inc UNIX OS to run on the
Power PCs in 1994 (MacWeek 04/05/93).  One of the few OSes to directly state
that it will run Windows/DOS programs.  IBM OS section for details
NeXTStep: possible port see IBM OS section for details.
OS Number Crunching (Mel Park)
Mac
Arithmetic is done in a consistent numerical environment {SANE or Standard
Apple Numerics Environment}. Floating point numbers are 96 bits long when an
FPU is present and 80 bits otherwise. Exceptions, such as dividing by zero or
taking the square root of a negative number, do not cause an abort but are
handled in a logically consistent manner. 1/0 produces the internal
representation for infinity (INF).  1/(1/0) produces zero. The above treatment
of 1/(1/0) occurs in an FPU-equipped machine even when SANE is bypassed and
the FPU programmed directly.
IBM
Floating point numbers are 80-bits with a hardware FPU, 64-bits when
emulated.  The way they are handled is dependent on the coding of whatever
compiler or assembler was used for a program. On older DOS complilers
exceptions could cause program aborts; 1/0 and 1/(1/0) would abort to the DOS
prompt at the point where they occured.  Most present compilers handle this
better.  Result: there is little consistent handling of numbers between DOS,
Windows and OS/2 programs nor between programs for just one OS.
Networking [Includes printing]
WYSIWYG printing can be a problem with either Mac of IBM machines especially
if one sends TrueType fonts to a older style PostScript printer.
Mac
Hardware: Built-in LocalTalk network port and a built-in printer port.
LocalTalk has moderate speeds (230.4 Kb/s) requires special connectors for
each machine ($15 and up) and can be run off of either the printer port {to
include very old macs} or the network port {standard today}.  Built-in
Ethernet is becoming common but many older Macs require a PDS or Nubus card at
about $150-$300 for each machine.  These cards provide three connectors and
transceivers {thick, thin, and 10BaseT} for Ethernet.
The Macintosh Quadra family and some Centris models includes Ethernet
interface on motherboard, with transceivers available. TokenRing has been a
network option since 1989.
Software: AppleTalk {the suite of protocols} standard with Mac OS, which can
use variety of media types.  AppleShare client software included with the OS
as well and can connect to file servers such as Novell Netware, 3Com 3+Open,
Banyan Vines, DEC Pathworks, Apple's AppleShare servers, System 7 File Sharing
machines, and AFP servers running on variety of UNIX hosts.  MacTCP allows
typical TCP/IP communications (telnet, ftp, NFS, rlogin).  A later version
will have Unix X/Open Transport Interface (XTI) built-in by the end of 1993
(MacWeek 04/12/93).  Third-party software to connect to NFS servers.  DEC
Pathworks provides DECnet support.  Peer-to-peer file sharing software
built-in to System 7.1 (See OS section).  Full server software is extra.
Printing requires connection of the printer and the printer being selected in
the chooser.  Changing printers is by selecting a different name in the
chooser.  The same is true of connecting to servers.
Printing bugs:  Monaco TrueType font is different then the screen bitmap font.
{QuickDraw QX is suppossed to fix this and similar problems.}
IBM
Hardware: LocalTalk [not widely used], Ethernet,  and TokenRing.
Software: Novell Netware, Banyan Vines, DECNet, Windows/Work Groups, AppleTalk
protocols, and AppleShare {subset of AppleTalk}.
Each of the MS-DOS networking schemes are, in general, totally incompatible
with the others. Once you have chosen one, you are pretty much locked-in to
that product line from then on.  Windows/Work Groups is a little more
forgiving and removes some of this problem.  Novell Netware is the biggest,
{~80 percent of the corporate market.} and in general is more powerful and
offers better control/management/security than AppleShare, but it's also more
complex to set up and manage.  This will change due to the use of the Mac
finder and file management system by Novell. (PC Week 12/14/92 & 12/28/92;
InfoWorld Dec 14/92; MacWeek 3/22/93)
Printing {Very OS dependent}
DOS: If it's a single user, then you plug the printer into the parallel port,
and don't worry about it {Tweeking may be needed with poorly written
software}.  Network Printing is not controlled by the system, but is mostly
implemented by the actual program, therefore performance varies from one
software program to the next.
Windows 3.x: supports standard drivers and can do a good job of showing "jobs"
in the print queue, but it always lists printers as "active"... even if they
are not.  This becomes a problem if there are several incompatible printers
on the same net, because there's no way for software to reliably determine
which printer is active right now.  Windows for Workgroups is more Mac-like
and intelligent about this.
OS/2: Mac-like; the os deals with printers, with apps making calls to the OS.
Printing bugs: due to poor programing some programs for all the above OSes do
not have WYSIWYG printing.  This is the fault of the programs in question and
not that of the OS involved.
Price issue: This is very dynamic with Mac providing more build-in features
than IBM and IBM being more 'get only what you need' then Mac and price wars
by both worlds.
The IBM machines' modualar nature prevents any kind of true hardware
standarization, which in turn requires OSes and programs to be very complex to
handle ALL the variation in hardware.  When one adds all the standard Mac
hardware features to an IBM {built-in input/output sound support, SCSI, PDS,
built-in monitor support, built-in networking, standard mouse interface, and
NuBus 90 in higher machines} the Mac tends to be cheaper then an equivalent
equipted IBM machine {Especially since some IBM monitors can be used with Macs
which cuts some more of the Mac's cost (MacUser Aug 1992:158-176)}.
Some prices using some of the info in this sheet and MacUser April 1993.
All Macs below come with a PDS slot, VRAM, and SCSI-1 built in.  Except where
noted, monitor is extra and a built-in monitor interface is provided {no card
needed except for 24-bit color display}.
IBM planned a $1,200 386SLC/25MHz model with a 60MB hard drive and color VGA
monitor {~VRAM} (MacWeek 8/17/92) {sounds like a Color Classic without SCSI-1,
sound support, built-in network support, FPU socket, built-in expansion to
16-bit color, etc}.
Color Classic:  $1,389 - 030/16MHz with 16-bit data bus {~386sx/20MHz
equivalent}, 4/80, FPU socket, and built-in monitor.
LCIII: $1,499 - 030/25MHz {~386dx/33MHz equivalent}, and 4/160.
Centris 610: $2,899 - 68LC040/20MHz {Depending on the program ~486sx/40 or
~'486dx2sx'/20[40]MHz equivalent}, 8/230, built-in ethernet, 300i CD-ROM, a
PDS/NuBus 90 slot and VRAM for 16-bit color.
Centris 650: 040/25MHz {Depending on the program ~486dx/50 MHz or 486dx2/50
MHz equivalent} with a PDS and 3 NuBus 90 slots. $3,189 {ethernet, 8/80};
$3,559 {ethernet, 8/230}; $3,999 {ethernet, 8/230, CD-ROM, VRAM for 16-bit

hat the Megadrives worked perfectly on both my
Mac Plus and my Powerbook 140.  It was for this reason I assumed
the problem had something to do with the Quadra.  Even with the
Quadra, they mostly worked OK.  The problem occurred when I ejected
a cartridge from a drive: it would start popping up dialog boxes
saying "This cartridge must be formatted with Jasmine Driveware"
even though there was no cartridge in the drive.

t to format) I have this confirmed from Apple Computer in Sweden (I work for a Apple dealer as a service tech). We had problems that Quadras wanted to format a diskette or a Syquest when ther was nothing in the drive. This problem was fixed sytem 7.1

Benchmarks are for marketing dweebs and CPU envy.  OK, if it will make

The point being the processor speed is only one of many aspects of a
computers performance.  Clock speed, processor, memory speed, CPU
architecture, I/O systems, even the application program all contribute
to the overall system performance.

the Q700 will only do 8bit or 24bit color.  if you want the higher

for a 21" monitor, you can get 8bit max.

Hmmm... Sounds vaguely similar to a problem I had a long time ago when I was
trying to use Kermit.  I was building a serial connection between my Duo 210
and my NeXT.  I think the problem was in the handshaking.  Basically, you need
to make sure that the handshaking protocol is the same on both sides.  A safe
place to start is by selecting NO handshaking on either end.  One problem is
that the Zilog serial chip seems to get permanently wedged if you talk to it
wrong, and only a reset will clear it.  I don't know the specifics.  But this
could be a nonlinearity that screws up your attempts at debugging the system.
It could very well be that you are doing things right--eventually-- but one
wrong move (like trying a bad handshaking protocol) can screw up any further
correct actions, until the next machine reset.  I have wedged my Mac and also
my NeXT that way.
Now I can send files back and forth between the Duo and the NeXT without any
problem, and at pretty high speeds too.
I don't know what kind of chip the PC uses, but I think the Zilog 8530 is
pretty standard.
Hope this helps,

The PowerBook 170 hardware doesn't have a wakeup timer.  Nor does the 140.
The Mac Portable had one, and I think the PowerBook 100 had one.  I don't

To the best of my knowledge there aren't any problems with Quadras and
blind transfers.  Trouble with blind transfers usually means the programmer
screwed up the TIBs or didn't test their driver with the device in question.
Well designed TIBs poll or loop at every point where delays of >16�sec occur.
This usually occurs at the first byte of each block of a transfer but some
devices can "hiccup" in the middle of blocks.  If this happens in the middle
of a blind transfer there is the possibility of losing or gaining a byte
depending on which direction the tranfer was going.  In anycase the SCSI Manager
will eventually return a phase error at the end of the transaction because
it is out of sync.  Actual data loss would only occur if the driver didn't
pay attention to the errors coming back.
Note that this effect is not caused by anything actually on the SCSI Bus but
rather by the transfer loops inside the SCSI Manager.  The problem occurs when
the processor bus errors trying to access the SCSI chip when the next byte
hasn't been clocked yet.  Also note that the Bus Error is dealt with by a bus
error handler and doesn't crash the machine...

A SIMM is a small PCB with DRAM chips soldered on.

Is this being done with the motherboard's SCSI interface? If this is possible
then a bit of experimenting with just plain old clock oscillators may be
in order. Give us some more details please.

The Logitech ScanMan 32 is a nice unit, compact and effective it will
bring in graphics with surprisingly good quality. Note that its effective
resolution in grey scale mode is only about 72 dpi. If you don't intend
to magnify a graphic, it works fine. A true 256 level gray scanner would
work better for images.
I've seen the ScanMan go for as little as $100 used. It is a reasonable buy
at that price. Higher end hand scanners are almost as expensive as used
flat bed scanners. Here is Seattle, the paper shows occasional good bargains
in the classifieds. Used color flat beds have been seen as lows as $500 lately.
Grey scale flatbeds come in around $300-$350.

In the May issue of C't Magazine was an article about upgrading 040 models
of apple. They simply change crystals and add a fan.
Hammerhead: Centris 610 was able to work with 25 MHz (cooler prefered)
and for 1000 DM you get an 68040 (33MHz) which works with the
appropriate crystal at full speed. (extra cooling required)
Centris 650 like Quadra 700 with extra cooling 33MHz works on
most machines and for real power enthusiasts they used a
Quadra 950 at 40 MHz wow! But for better description you should
get this issue of C't (a german PC magazine!)

There is one reason: market size.
The market size for color quickdraw for accellerated plusses and
SEs (which don't go beyond 4 MB anyway) is just too small; the
extra cost would belike $1,000 and with that money, you can buy a
color classic instead.

Summary: Quadra Clock Chip Swap Success
Keywords: Quadra,clock,accelerate
After reading reports from Germany of success in accelerating a Quadra
or Centris simply by changing the clock oscillator, I decided to test the
claim. I pulled out my Variable Speed Overdrive and the motherboard's
50 mhz clock chip. I put a socket in the clock's place and inserted a
64 mhz TTL clock oscillator I had left over from working on some SI's.
I can't believe it. It actually works. I'm not getting SCSI timing errors
either. This is only after a short run time but I'll keep posting results.
Did I spend all that money on the VSO for nothing? If this keeps working,
the lack of a double boot in itself will be worth the effort.

A 256K DRAM chip is a 256 kilobit chip whereas a 256K SIMM is a 256
kilobyte memory module. The SIMM is a PCB with a 30 pin connector edge
and on the SIMM are 8 256 kilobit DRAM chips (making the total memory 256
KBytes.
You are correct assuming that SIMMs will not fit into a LaserWriter.
Apple printers either require 64 pin SIMMs like those in the Mac IIfx or
special memory chips. Contact your Apple dealer to find out exactly what
kind of chips you need.

Can some people with cache cards PLEASE post speedometer numbers they get
with the cards. I have only one report, which seems to indicate that
a 32K cache card gives you only about a 1% speedup!! Access to memory takes
LONGER when you have a cache card(and get a miss) thus a small cache card
of 32K may be worth $0. I don't know what kind of numbers 64K cards get
you. Also I found it interesting that you can disable the cache cards
via software(read about it in the Mac IIsi tech notes from ftp.apple.com)
So is $99 a good deal or not, I still don't know.

Hi there!
Could some kind soul tell me what is the price of LC/IIvi/IIvx
compatible 512kb VRAM SIMMs in the US nowadays? The price over here
(Finland) is so ridiculously high (about $185 each in USD) that I
think it is worth the trouble to try to get them overseas.
Thanks

The si has a single expansion slot, that can be either PDS or Nubus, but not
both together. The card lies parallel to and above the motherboard & HD and
requires an adaptor slot to do this. There are Nubus and PDS adaptort cards.
Thus, what kind of slots you have depends on what kind of adapter card you
have. With the exception of the Radius rocket, all NuBus cards I know of work
in the si. PDS slots and thus cards are Mac specific, thus not all PDS cards
work in all Macs.

Hi there!
I wonder if anyone knows and can recommend me a good NuBus display
card for driving a 14" multisync (NEC 3D)?
The NEC 3D can do horizontal refresh from 15.5 kHz to 38 kHz and
vertical from 50 Hz to 90 Hz and can do max 1024x768 interlaced,
though I am looking for something more like 800x600 or 832x624
noninterlaced.
It would be very nice to find a card which can be programmed quite
freely within these limits and is capable to display at least
8bits/pixel, preferably more.
Is there anything on the market that comes even close?
Thanks

Hi there!
What is your recommendation for a good hard-disk driver software for
non-Apple drives? I would mainly need it for a SyQuest removable media
drive, but maybe for some normal drives too.
I have heard and seen good things about SilverLining, but don't know
any competitors. It does not need to be fancy, filled with features...
I more like it affordable.

None. You need to buy 2 80ns 256k VRAM SIMMs. They cost about $30
each from your favorite memory distributor.

The 512k is soldered to the logic board. There are 2 SIMM slots for

Could be better caching on the disk.
Could be faster coil for seeks.
Could be that the disk spins faster so data transfers faster.
Could be that data is packed tighter so it transfers faster.
Could be a faster SCSI command decoder in the drive.
Among other things...

You need to add two 256K VRAM SIMMs;  512K VRAM SIMMs will not work in any
of the Quadra or Centris machines.  There is already 512K of VRAM soldered
to the logic board.  You add the two 256K SIMMs to this to give you a
total of 1 MB.

Ok.  I have a record that shows a IIsi with and without a 64KB cache.
It's small enough that I will attach it.
I have also measured some real programs with and without the 64 KB
cache.  The speedup varies a lot from app to app, ranging from 0% to
40%.  I think an average of 20%-25% is about right.  The subjective
difference is not great, but is sometimes noticable.  A simple cache
card certainly does not transform a IIsi into something enormously
better.  I do not have an FPU.
The conventional wisdom says that cache cards from all of the makers
offer about the same speedup and that there is not much difference
between 32K and 64K caches.  I bought mine from Third Wave for well
under $150.  I have had absolutely no problems at all with it.
If you get *complete* speedometer runs for a 32K cache, I'd like to
see them.  Let's check the conventional wisdom!  The so called
"Performance Rating" numbers by themselves are of no interest.
Cheers.

What I did NOT get with my drive (CD300i) is the System Install CD you
listed as #1.  Any ideas about how I can get one?  I bought my IIvx 8/120
from Direct Express in Chicago (no complaints at all -- good price & good
service).
BTW, I've heard that the System Install CD can be used to boot the mac;
however, my drive will NOT accept a CD caddy is the machine is off.  How can
you boot with it then?

The Sound Driver is pretty ok, since it's fast. Sound Manager used by the
book is *useless*. Disposing of sound channels as soon as sound has completed
is out of the question for games with smooth animation. (It's too slow.)
The Sound Driver is so much snappier than Sound Manager. Unfortunately,
System 7 supports it poorly, making programs crash occasionally.

Well, I want my code to work on old systems too. I don't know about sys 7.1,
but at least on 6.0.7, there are bugs in the Sound Manager that causes
channels to hang (with no error message). This happends when I keep a
channel open for long periods - necessary for performance - and play many
sounds, stopping sounds halfway. Callbacks seems not to be reliable.
Then only way I can safely tell if a sound has stopped playing is to
inspect private variables in the channel (QHead, I think it was), and the
only way I have found to tell if a channel is hung is to inspect an
*undocumented* flag and modify it.
Am I happy with this? Nope. I consider writing to SoundBase simply to get
rid of the bugs.
Any better suggestions? (Silent games is not among the acceptab|e solutions.)

I am trying to put a 40MB drive from my LC into a case.  It is a Conner
CP3040A.  I can't figure out which jumpers are the SCSI ID jumpers.
Is anyone familiar with this drive?
At the end of the drive (oposite the 50 pin pibbon connector), there
are eleven pins which look like this:
o o o o o   o   1
o o o o   o   2
L5  CR12   C37
where the "o" are pins, and the "L5 CR12 C37" represent some of the
silk screen notation near these pins.
Elsewhere on the board there are four jumper pads marked E1,E2,E3,E4
on the silk screen.
Does anyone know where the SCSI ID A0,A1,A2 pins are, and where the
drive activity light LED should be plugged into?

The first time this happened removing both power adaptor and battery
for ~1 minute brought the machine back.
The second time this happened the machine wouldn't wake up until
powered down for about 30 minutes.  The screen had what looked
like red horizontal lines accross it.

to maintain compatibility with original QD---I think of things like
where you have to cast CGrafPorts to GrafPorts and such. It would be a
lot cleaner to ditch this entire mess and start over---do we get that?

Is there a workaround which will enable me to print to a HPLJ4 from my
Powerbook 100? (Actually I'm going to a 4M which will have an Ethernet card in
the LocalTalk slot!!!GRRRRR). Is there some hardware which will enable me to
this easily (kind of plug and play!).
Thanks, Pam Mullen

X    * To show the importance of programming style, in an ironic way.
X    * To stress C compilers with unusual code.
X    * To illustrate some of the subtleties of the C language.
X    * To provide a safe forum for poor C code.  :-)
X
X
XRULES:
X
X    To help us with the volume of entries, we ask that you follow these rules:
X
X    1) Your entry must be a complete program.
X
X    2) Your entry must be <= 3217 bytes in length.  The number of characters
X       excluding whitespace (tab, space, newline), and excluding any ; { or }
X       followed by either whitespace or end of file, must be <= 1536.
X
X    3) Your entry must be submitted in the following format:
X
X---entry---
Xrule:	1993
Xfix:	y or n   (n => this is a new entry, y => this replaces an older entry)
Xtitle:	title of entry  		    (see comments below)
Xentry:	Entry number from 0 to 7 inclusive  (your 1st entry should by 0)
Xdate:	Date/time of submission in UTC	    (see comments below)
Xhost:	Machine(s) and OS(s) under which your entry was tested
X	Use tab indented lines if needed
X---remark---
X    Place remarks about this entry in this section.  It would be helpful if
X    you were to indent your remarks with 4 spaces, though it is not a
X    requirement.  Also, if possible, try to avoid going beyond the 79th
X    column.  Blank lines are permitted.
X---author---
Xname:	your name
Xorg:	School/Company/Organization
Xaddr:	postal address
X	use tab indented lines to continue
X	don't forget to include the country
Xemail:  Email address from a well known site or registered domain.
X        If you give several forms, list them on separate tab indented lines.
Xanon:	y or n   (y => remain anonymous, n => ok to publish this info)
X---info---
XIf your program needs an info file, place a uuencoded copy of it in
Xthis section.  In the case of multiple info files, use multiple info
Xsections.  If your entry does not need a info file, skip this section.
X---build---
XPlace a uuencoded copy of the command(s) used to compile/build your program
Xin this section.  It must uudecode into a file named 'build'.  The resulting
Xfile must be 255 bytes or less.
X---program---
XPlace a uuencoded copy of your program in this section.  It must uudecode
Xinto a file named is 'prog.c'.  The resulting file must follow rule #2.
X---end---
X
X      Regarding the above format:
X
X	* The title must match the expression: [a-zA-Z0-9_=][a-zA-Z0-9_=+-]*
X	  and must be 1 to 12 characters in length.
X
X	  It is suggested, but not required, that the title should
X	  incorporate your username; in the case of multiple authors,
X	  consider using parts of the usernames of the authors.
X
X	* The date in the ---entry--- section should be given with respect
X	  to UTC.  The format of the date should be as returned by asctime()
X	  using the C locale.  (see guidelines for more info)
X
X	* You may correct/revise a previously submitted entry by sending
X	  it to the contest email address.  Be sure to set 'fix' in the
X	  ---entry--- section to 'n'.  The corrected entry must use the same
X	  title and entry number as submittion that is being corrected.  Be
X	  sure that you note the resubmittion in the ---remark--- as well.
X
X	* With the exception of the header, all text outside of the above
X	  format may be ignored by the judges.  If you need tell the judges
X	  something, put it in the ---remark--- section, or send a separate
X	  Email message to the judges.
X
X	* Information from the ---author--- section will be published unless
X	  'y' was given to the respective author's 'anon' line.
X
X	* To credit multiple authors, include an ---author--- section for
X	  each author.  Each should start with ---author--- line, and
X	  should be found between the ---entry--- and ---build--- sections.
X
X	* The entry's remarks should include:
X	    - what this program does
X	    - how to run the program (sample args or input)
X	    - special compile or execution instructions, if any
X	    - special filename requirements (see rule 4 and 5)
X	    - information about any ---data--- files
X	    - why you think the program is obfuscated
X	    - note if this entry is a re-submission of a previous entry.
X	    - any other remarks (humorous or otherwise)
X
X	* Do not rot13 your entry's remarks.  You may suggest that certain
X	  portions of your remarks be rot13ed if your entry wins an award.
X
X        * Info files should be used only to supplement your entry.  They
X	  should not be required to exist.
X
X	  If your entry does not need an info file, skip the ---info---
X	  section.  If your entry needs multiple info files, use multiple
X	  ---info--- sections, one per info file.  You should describe
X	  each info file in the ---remark--- section.
X
X    4) If your entry is selected as a winner, it will be modified as follows:
X
X	   'build' is incorporated into a makefile, and 'build' is removed
X	   'prog.c' is renamed to your entry's title, followed by an optional
X	       digit, followed by '.c'
X	   your entry is compiled into a file with the name of your entry's
X	       title, possibly followed by a digit
X
X       If your entry requires that a build file exist, state so in your
X       entry's remark section.  The makefile will be arranged to execute a
X       build shell script containing the 'build' information.  The name of
X       this build shell script will be your entry's title, possibly followed
X       by a digit, followed by '.sh'.
X
X       If needed, your entry's remarks should indicate how your entry must
X       be changed in order to deal with the new filenames.
X
X    5) The build file, the source and the resulting executable should be
X       treated as read-only files.  If your entry needs to modify these files,
X       it should make and modify a copy of the appropriate file.  If this
X       occurs, state so in your entry's remarks.
X
X    6) Entries that cannot be compiled by an ANSI C compiler will be rejected.
X       Use of common C (K&R + extensions) is permitted, as long as it does not
X       cause compile errors for ANSI C compilers.
X
X    7) The program must be of original work.  All programs must be in the
X       public domain.  All copyrighted programs will be rejected.
X
X    8) Entries must be received prior to 07-May-93 0:00 UTC.  (UTC is
X       essentially equivalent to Greenwich Mean Time)  Email your entries to:
X
X		...!{apple,pyramid,sun,uunet}!hoptoad!obfuscate
X		obfuscate@toad.com
X
X       We request that your message use the subject 'ioccc entry'.
X
X       If possible, we request that you hold off on Emailing your entries
X       until 1-Mar-93 0:00 UTC.  Early entries will be accepted, however.
X       We will attempt to email a confirmation to the the first author for
X       all entries received after 1-Mar-93 0:00 UTC.
X
X    9) Each person may submit up to 8 entries per contest year.  Each entry
X       must be sent in a separate Email letter.
X
X   10) Entries requiring human interaction to be built are not allowed.
X       Compiling an entry produce a file (or files) which may be executed.
X
X   11) Programs that require special privileges (setuid, setgid, super-user,
X       special owner or group) are not allowed.

X10th International Obfuscated C Code Contest Guidelines, Hints and Comments

XCopyright (c) Landon Curt Noll & Larry Bassel, 1993.

X
XABOUT THIS FILE:
X
X    This file is intended to help people who wish to submit entries to
X    the International Obfuscated C Code Contest (IOCCC for short).
X
X    This is not the IOCCC rules, though it does contain comments about
X    them.  The guidelines should be viewed as hints and suggestions.
X    Entries that violate the guidelines but remain within the rules are
X    allowed.  Even so, you are safer if you remain within the guidelines.
X
X    You should read the current IOCCC rules, prior to submitting entries.
X    The rules are typically sent out with these guidelines.
X
X
XWHAT IS NEW IN 1993:
X
X    The entry format is better (for us anyway).  The program mkentry.c
X    has been updated.  See ENTRY FORMAT.
X
X    We will reject entries that cannot be compiled using an ANSI C
X    compiler.  Certain old Obfuscation hacks that cause ANSI C compilers
X    fits are no longer permitted.  Some of the new issues deal with
X    non-integral array types, variable number of arguments, C preprocessor
X    directives and the exit() function.  See OUR LIKES AND DISLIKES.
X
X
XHINTS AND SUGGESTIONS:
X
X    You are encouraged to examine the winners of previous contests.  See
X    FOR MORE INFORMATION for details on how to get previous winners.
X
X    Keep in mind that rules change from year to year, so some winning entries
X    may not be valid entries this year.  What was unique and novel one year
X    might be 'old' the next year.
X
X    An entry is usually examined in a number of ways.  We typically apply
X    a number of tests to an entry:
X
X	* look at the original source
X	* convert ANSI tri-graphs to ASCII
X	* C pre-process the source ignoring '#include' lines
X	* C pre-process the source ignoring '#define' and '#include' lines
X	* run it through a C beautifier
X	* examine the algorithm
X	* lint it
X	* compile it
X	* execute it
X
X    You should consider how your entry looks in each of the above tests.
X    You should ask yourself if your entry remains obscure after it has been
X    'cleaned up' by the C pre-processor and a C beautifier.
X
X    Your entry need not do well under all, or in most tests.  In certain
X    cases, a test is not important.  Entries that compete for the
X    'strangest/most creative source layout' need not do as well as
X    others in terms of their algorithm.  On the other hand, given
X    two such entries, we are more inclined to pick the entry that
X    does something interesting when you run it.
X
X    We try to avoid limiting creativity in our rules.  As such, we leave
X    the contest open for creative rule interpretation.  As in real life
X    programming, interpreting a requirements document or a customer request
X    is important.  For this reason, we often award 'worst abuse of the
X    rules' to an entry that illustrates this point in an ironic way.
X
X    If you do plan to abuse the rules, we suggest that you let us know
X    in the remarks section.  Please note that an invitation to abuse
X    is not an invitation to break.  We are strict when it comes to the
X    3217 byte size limit.  Also, abusing the entry format tends to
X    annoy more than amuse.
X
X    We do realize that there are holes in the rules, and invite entries
X    to attempt to exploit them.  We will award 'worst abuse of the rules'
X    and then plug the hole next year.  Even so, we will attempt to use
X    the smallest plug needed, if not smaller.  :-)
X
X    Check out your program and be sure that it works.  We sometimes make
X    the effort to debug an entry that has a slight problem, particularly
X    in or near the final round.  On the other hand, we have seen some
X    of the best entries fall down because they didn't work.
X
X    We tend to look down on a prime number printer, that claims that
X    16 is a prime number.  If you do have a bug, you are better off
X    documenting it.  Noting "this entry sometimes prints the 4th power
X    of a prime by mistake" would save the above entry.  And sometimes,
X    a strange bug/feature can even help the entry!  Of course, a correctly
X    working entry is best.
X
X
XOUR LIKES AND DISLIKES:
X
X    Doing masses of #defines to obscure the source has become 'old'.  We
X    tend to 'see thru' masses of #defines due to our pre-processor tests
X    that we apply.  Simply abusing #defines or -Dfoo=bar won't go as far
X    as a program that is more well rounded in confusion.
X
X    Many ANSI C compilers dislike the following code, and so do we:
X
X	#define d define
X	#d foo		   <-- don't expect this to turn into #define foo
X
X	int i;
X	j;		   <-- don't use such implicit type declaration
X	int k;
X
X    We suggest that you compile your entry with an ANSI C compiler.  If you
X    must use non-ANSI C, such as K&R C, you must avoid areas that result in
X    compile/link errors for ANSI C compilers.
X
X    Unfortunately, ANSI C requires array indexes to be of integral type.
X    Thus, the following classical obfuscation hacks are no longer allowed:
X
X	int i;
X	char *c;
X	i[c];		   <--- use c[i] instead
X	(i+3)["string"];   <--- use "string"[i+3] instead
X
X    If your entry uses functions that have a variable number of
X    arguments, be careful. Systems implement va_list as a wide variety
X    of ways.  Because of this, a number of operations using va_list are
X    not portable and must not be used:
X
X	* assigning a non-va_list variable to/from a va_list variable
X	* casting a non-va_list variable into/from a va_list variable
X	* passing a va_list variable to a function expecting a non-va_list arg
X	* passing a non-va_list variable to a function expecting a va_list arg
X	* performing arithmetic on va_list variables
X	* using va_list as a structure or union
X
X    In particular, do not treat va_list variables as if they were a char **'s.
X
X    Avoid using <varargs.h>, use <stdarg.h> instead.
X
X    If you use C preprocessor directives (#define, #if, #ifdef, ...),
X    the leading '#' must be the first character on a line.  While some
X    C preprocessors allow whitespace the leading '#', many do not.
X
X    Because the exit() function returns void on some systems, entries
X    must not assume that it returns an int.
X
X    Small programs are best when they are short, obscure and concise.
X    While such programs are not as complex as other winners, they do
X    serve a useful purpose.  They are often the only program that people
X    attempt to completely understand.  For this reason, we look for
X    programs that are compact, and are instructional.
X
X    One line programs should be short one line programs, say around 80
X    bytes long.  Getting close to 160 bytes is a bit too long in our opinion.
X
X    We tend to dislike programs that:
X
X	* are very hardware specific
X	* are very OS or Un*x version specific
X	     (index/strchr differences are ok, but socket/streams specific
X	      code is likely not to be)
X	* dump core or have compiler warnings
X	     (it is ok only if you warn us in the 'remark' header item)
X	* won't compile under both BSD or SYS V Un*x
X	* abusing the build file to get around the size limit
X	* obfuscate by excessive use of ANSI tri-graphs
X	* are longer than they need to be
X	* are similar to previous winners
X	* are identical to previous losers  :-)
X
X    Unless you are cramped for space, or unless you are entering the
X    'best one liner' category, we suggest that you format your program
X    in a more creative way than simply forming excessively long lines.
X
X    The build file should not be used to try and get around the size
X    limit.  It is one thing to make use of a several -D's to help out,
X    but it is quite another to use 200+ bytes of -D's in order to
X    try and squeeze the source under the size limit.  You should feel
X    free to make use of the build file space, but you are better off
X    if you show some amount of restraint.
X
X    We allowed whitespace, and in certain cases ; { or } do not impact
X    your program size (up to a certain point), because we want to get
X    away from source that is simply a compact blob of characters.
X
X    Given two versions of the same program, one that is a compact blob
X    of code, and the other that is formatted more like a typical C
X    program, we tend to favor the second version.  Of course, a third
X    version of the same program that is formatted in an interesting
X    and/or obfuscated way, would definitely win over the first two!
X
X    We suggest that you avoid trying for the 'smallest self-replicating'
X    program.  We are amazed at the many different sizes that claim
X    to be the smallest.  There is nothing wrong with self-replicating
X    programs.  In fact, a number of winners have been self-replicating.
X    You might want to avoid the claim of 'smallest', lest we (or others)
X    know of a smaller one!
X
X    X client entries should be as portable as possible.  Entries that
X    adapt to a wide collection of environments will be favored.  Don't
X    depend on a particular type of display.  For example, don't depend
X    on color or a given size.  Don't require backing store.
X
X    X client entries should avoid using X related libraries and
X    software that is not in wide spread use.  We ask that such X client
X    entries restrict themselves to only the low level Xlib and the
X    Athena widget set (libX11.a, libXaw.a, libXmu.a and libXt.a).
X    Don't use M*tif, Xv*ew, or OpenL*ok toolkits, since not everyone
X    has them.  Avoid depending on a particular window manager.  Not
X    everyone has X11r5, and some people are stuck back in X11r4 (or
X    earlier), so try to target X11r5 without requiring X11r5.  Better
X    yet, try to make your entry run on all version 11 X Window Systems.
X
X    X client entries should not to depend on particular items on
X    .Xdefaults.  If you must do so, be sure to note the required lines
X    in the ---remark--- section.
X
X    We like programs that:
X
X	* are as concise and small as they need to be
X	* do something at least quasi-interesting
X	* pass lint without complaint (not a requirement, but it is nice)
X	* are portable
X	* are unique or novel in their obfuscation style
X	* MAKE USE OF A NUMBER OF DIFFERENT TYPES OF OBFUSCATION
X	* make us laugh and/or throw up  :-)
X
X    Some types of programs can't excel in some areas.  Of course, your
X    program doesn't have to excel in all areas, but doing well in several
X    areas really does help.
X
X    We freely admit that interesting, creative or humorous comments in
X    the ---remark--- section helps your chance of winning.  If you had to
X    read of many twisted entries, you too would enjoy a good laugh or two.
X    We think the readers of the contest winners do as well.
X
X    Be creative!
X
X
XENTRY FORMAT:
X
X    In order to help us process the many entries, we must request your
X    assistance by formatting your entries in a certain way.  This format,
X    in addition, allows us to quickly separate information about the
X    author from the program itself.  (see JUDGING PROCESS)
X
X    We have provided the program, mkentry, as an example of how to
X    format entries.  You should be aware of the following warning that
X    is found in mkentry.c:
X
X	This program attempts to implement the IOCCC rules.  Every
X	attempt has been made to make sure that this program produces
X	an entry that conforms to the contest rules.  In all cases,
X	where this program differs from the contest rules, the
X	contest rules will be used.  Be sure to check with the
X	contest rules before submitting an entry.
X
X    You are not required to use mkentry.  It is convenient, however,
X    as it attempts to uuencode the needed files, and attempt to check
X    the entry against the size rules.
X
X    If you have any suggestions, comments, fixes or complaints about
X    the mkentry.c program, please send Email to the judges.  (see below)
X
X    The following is a sample entry:
X
X---entry---
Xrule:	1993
Xfix:	n
Xtitle:	chonglab

Xdate:	Mon Mar  1 08:45:20 1993
Xhost:	Un*x v6, pdp11/45
X	2.9BSD, pdp11/70
X---remark---
X    This is a non-obfuscated obfuscated C program.
X
X    It is likely not to win a prize.  But what do you expect from
X    a short example!

X
X    Typically the build file should assume that the source is prog.c
X    and will compile into prog.  If an entry wins, we will rename
X    its source and binary to avoid filename collision.  By tradition,
X    we use the name of the entry's title, followed by an optional
X    digit in case of name conflicts.
X
X    If the above entry somehow won the 'least likely to win' award,
X    we would use chonglab.c and chonglab.
X
X    If your entry depends on, or requires that your build, source
X    and/or binary files be a particular name, please say so in the
X    ---remark--- section.  If this case applies, it would be be helpful
X    if you did one of the following:
X
X	* Tell us how to change the filename(s) in your entry.
X
X	* Have the build file make copies of the files.  For example:
X
X		cc prog.c -o special_name		need special binary
X
X	    or  rm -f special_src.c			need special source
X		cp prog.c special_src.c
X		cc special_src.c -o special_name
X
X	    or  rm -f special_build			need special build
X		tail +4 build > special_build
X		sh < special_build
X
X	* Assume that we will use the entry title.  Send us a version of
X	  your build/program files that uses the name convention.  You
X	  should uuencode these files in ---data--- sections.
X
X    If your entry needs to modify its source, info or binary files,
X    please say so in the ---remark--- section.  You should try to avoid
X    touching your original build, source and binary files.  You should
X    arrange to make copies of the files you intend to modify.  This
X    will allow people to re-generate your entry from scratch.
X
X    Remember that your entry may be built without a build file.  We
X    typically incorporate the build lines into a Makefile.  If the
X    build file must exist, say so in the ---remark--- section.
X
X    If your entry needs special info files, you should uuencode them
X    into ---info--- sections.  In the case of multiple info files,
X    use multiple ---info--- sections.  If no info files are needed,
X    then skip the ---info--- section.
X
X    Info files are intended to be input, or detailed information that
X    does not fit well into the ---remark--- section.  For example, an
X    entry that implements a compiler might want to provide some sample
X    programs for the user to compile.  An entry might want to include a
X    lengthy design document, that might not be appropriate for a
X    'hints' file.
X
X    Info files should be used only to supplement your entry.  For
X    example, info files may provide sample input or detailed
X    information about your entry.  Because they are supplemental,
X    the entry should not require them exist.
X
X    In some cases, your info files might be renamed to avoid name
X    conflicts.  If info files should not be renamed for some reason,
X    say so in the ---remark--- section.
X
X    Info files must uudecode into the current directory.  If they
X    absolutely must be renamed, or moved into a sub-directory, say
X    so in the ---remark--- section.
X
X    When submitting multiple entries, be sure that each entry has
X    a unique entry number from 0 to 7.  Your first entry should
X    have entry number 0.
X
X    With the exception of the header, all text outside of the entry
X    format may be ignored.  That is, don't place text outside of the
X    entry and expect the judges to see it.  (Our decoding tools aren't
X    AI progs!) If you need tell the the something, put it in the
X    ---remark--- section, or send a Email to the judges at:
X
X	...!{apple,pyramid,sun,uunet}!hoptoad!judges	(not the address for
X	judges@toad.com					 submitting entries)
X
X    The date should be given with respect to UTC.  (Some systems refer
X    to this as GMT or GMT0)  The format of the date should be that as
X    returned by asctime() in the C locale.  An example of such a string is:
X
X	Thr Apr 01 00:47:00 1993
X
X    This format is similar to the output of the date(1) command.  The
X    string does not include the timezone name before the year.  On many
X    systems, one of the following command will produce a similar string:
X
X	date -u "+%a %h %d %T 19%y"
X	date -u | sed -e 's/... \(19[0-9][0-9]\)$/\1/'
X	sh -c 'TZ=UTC date | sed -e "s/... \(19[0-9][0-9]\)$/\1/"'
X	sh -c 'TZ=GMT date | sed -e "s/... \(19[0-9][0-9]\)$/\1/"'
X	sh -c 'TZ=GMT0 date | sed -e "s/... \(19[0-9][0-9]\)$/\1/"'
X
X    You are allowed to update/fix/revise your entry.  To do so, set
X    the 'fix' line in the ---entry--- section to 'y' instead of 'n'.
X    Be sure that the resubmittion uses the same title and entry number
X    as well, as these are used to determine which entry is to be
X    replaced.
X
X
XJUDGING PROCESS:
X
X    Entries are judged by Larry Bassel and Landon Curt Noll.
X
X    Entries are unpacked into individual directories.  The Email message
X    is unpacked into individual files, each containing:
X
X	---entry--- section
X	all ---author--- sections
X	all ---info--- sections
X	---build--- section
X	---program--- section
X	any other text, including the Email message headers
X
X    Prior to judging, the 'any other text' file is scanned to be sure
X    it does not contain useful information (or in case the entry was
X    malformed and did not unpack correctly).  Information from the
X    ---author--- sections are not read until the judging process is
X    complete, and then only from entries that have won an award.
X
X    The above process helps keep us biased for/against any one particular
X    individual.  We are usually kept in the dark as much as you are
X    until the final awards are given.  We like the surprise of finding
X    out in the end, who won and where they were from.
X
X    We attempt to keep all entries anonymous, unless they win an award.
X    Because the main 'prize' of winning is being announced, we make all
X    attempts to send non-winners into oblivion.  We remove all non-winning
X    files, and shred all related paper.  By tradition, we do not even
X    reveal the number of entries that we received.  (for the curious,
X    we do indicate the volume of paper consumed when presenting the IOCCC
X    winners at talks)
X
X    After the Usenix announcement, we attempt to send Email to the
X    authors of the winning entries.  One reason we do this is to give
X    the authors a chance to comment on the way we have presented their
X    entry.  They are given the chance to correct mistakes, typos.  We
X    often accept their suggestions/comments about our remarks as well.
X    This is done prior to posting the winners to the wide world.
X
X    Judging consists of a number of elimination rounds.  During a round,
X    the collection of entries are divided into two roughly equal piles;
X    the pile that advances on to the next round, and the pile that does
X    not.  We also re-examine the entries that were eliminated in the
X    previous round.  Thus, an entry gets at least two readings.
X
X    A reading consists of a number of actions:
X
X	* reading the ---entry--- section
X	* reading the uudecoded ---build--- section
X	* reading the uudecoded ---program--- section
X	* reading the uudecoded ---info--- section(s), if any
X	* passing the source thru the C pre-processor
X	    shipping over any #include files
X	* performing a number of C beautify/cleanup edits on the source
X	* passing the beautified source thru the C pre-processor
X	    shipping over any #include files
X
X    In later rounds, other actions are performed:
X
X	* linting the source
X	* compiling/building the source
X	* running the program
X	* performing misc tests on the source and binary
X
X    Until we reduce the stack of entries down to about 25 entries, entries
X    are judged on an individual basis.  An entry is set aside because it
X    does not, in our opinion, meet the standard established by the round.
X    When the number of entries thins to about 25 entries, we begin to form
X    award categories.  Entries begin to compete with each other for awards.
X    An entry often will compete in several categories.
X
X    The actual award category list will vary depending on the types of entries
X    we receive.  A typical category list might be:
X
X	* best small one line program
X	* best small program
X	* strangest/most creative source layout
X	* most useful obfuscated program
X	* best game that is obfuscated
X	* most creatively obfuscated program
X	* most deceptive C code
X	* best X client (see OUR LIKES AND DISLIKES)
X	* best abuse of ANSI C
X	* worst abuse of the rules
X	* <anything else so strange that it deserves an award>
X
X    We do not limit ourselves to this list.  For example, a few entries are so
X    good/bad that they are declared winners at the start of the final round.
X    We will invent awards categories for them, if necessary.
X
X    In the final round process, we perform the difficult tasks of
X    reducing the remaining entries (typically about 25) down to 8 or 10
X    winners.  Often we are confident that the entries that make it into
X    the final round are definitely better than the ones that do not
X    make it.  The selection of the winners out of the final round, is
X    less clear cut.
X
X    Sometimes a final round entry good enough to win, but is beat out
X    by a similar, but slightly better entry.  For this reason, it is
X    sometimes worthwhile to re-enter an improved version of an entry
X    that failed to win in a previous year.  This assumes, of course,
X    that the entry is worth improving in the first place!
X
X    More often that not, we select a small entry (usually one line), a
X    strange/creative layout entry, and an entry that abuses the contest
X    rules in some way.
X
X    In the end, we traditionally pick one entry as 'best'.  Sometimes such
X    an entry simply far exceeds any of the other entry.  More often, the
X    'best' is picked because it does well in a number of categories.
X
X
XANNOUNCEMENT OF WINNERS:
X
X    The first announcement, occurs at a Summer Usenix conference.  By tradition,
X    this is done during the latter part of the UUNET/IOCCC BOF, just prior to
X    the Berkeley BSD, and BSDI BOF.
X
X    Winning entries will be posted in late June to the following groups:
X
X	    comp.lang.c		  comp.unix.wizards	alt.sources
X
X    In addition, pointers to these postings are posted to the following
X
X	    comp.sources.d	  alt.sources.d		misc.misc
X	    comp.sources.misc	  comp.windows.x
X
X    Winning entries will be deposited into the uunet archives.  See
X    below for details.
X
X    Often, winning entries are published in selected magazines.  Winners
X    have appeared in books ("The New Hackers Dictionary") and on T-Shirts.
X
X    Last, but not least, winners receive international fame and flames!  :-)

X    10th International Obfuscated C Contest
X
X	"The original obfuscated contest"
X
X    Obfuscate:  tr.v.  -cated, -cating, -cates.  1. a.  To render obscure.
X                b.  To darken.  2. To confuse:  Their emotions obfuscated
X		their judgment.  [LLat. obfuscare, to darken : ob(intensive) +
X                Lat. fuscare, to darken < fuscus, dark.] -obfuscation n.
X                obfuscatory adj.
X
X    GOALS OF THE CONTEST:
X
X        * To write the most Obscure/Obfuscated C program under the rules below.
X        * To show the importance of programming style, in an ironic way.
X        * To stress C compilers with unusual code.
X        * To illustrate some of the subtleties of the C language.
X        * To provide a safe forum for poor C code.  :-)
X
X    The IOCCC is the grandfather of USENET programming contests.  Since
X    1984, this contest demonstrated that a program that mearly works
X    correctly is not sufficient.  The IOCCC has also done much to add
X    the arcane word 'obfuscated' back into the English language.
X    (see "The New Hacker's Dictionary" by Eric Raymond)
X
X    You are strongly encouraged to read the new contest rules before
X    sending any entries.  The rules, and sometimes the contest Email
X    address itself, change over time.  A valid entry one year may
X    be rejected in a later year due to changes in the rules.  The typical
X    start date for contests is in early March.  Contest rules are normally not
X    finalized and posted until the beginning of the contest.  The typical
X    closing date for contests are in early May.
X
X    The contest rules are posted to comp.unix.wizards, comp.lang.c,
X    misc.misc, alt.sources and comp.sources.d.  If you do not have access
X    to these groups, or if you missed the early March posting, you may
X    request a copy from the judges, via Email, at;
X
X        judges@toad.com   -or-   ...!{sun,uunet,utzoo,pyramid}!hoptoad!judges

X	By: Landon Noll & Larry Wall
X
X    This content is being planned.  Someday when Landon & Larry are not too
X    busy, they will actually get around to posting the first set of rules!
X
X    Landon says: "Yes, I know that I said we would have a contest in 1993,
X		  but other existing projects got in the way.  Hopefully
X		  something will be developed after Nov 1993."

X                         Alena Lacova (alena@nikhef.nl)
X
X    A  contest of  programming skills  and  knowledge, exclusively  for the
X    PostScript programming language. Its purpose:
X
X    * To spread knowledge of PostScript and its details.
X    * To applaud those with the best tricks.
X    * To prove  that humans can  beat those damnable  machine generators at
X      their own game by writing  the most obscure and mysterious PostScript
X      programs ever.
X
X    Winners will receive the fame and attention that goes with having their
X    program entry posted as a winner to programmers world-wide.
X
X    The 1993 contest rules and results are available by ftp as
X    ``wilma.cs.brown.edu:pub/postscript/obfuscated*.shar'', or individually
X    in the obfuscated directory. The judges will post the 1994 rules
X    in November to comp.lang.postscript on Usenet, and other places.
X    Send questions to jgm@cs.brown.edu.
X
X    Categories include: Best Obfuscated PostScript, Best Artwork,
X    Most Compact, Best Interactive Program, Most Useful, and
X    anything so unusual and creative that it deserves an award.
X
X    The judges will choose the winners of each category.
X
X    Alena Lacova  is a system  administrator at NIKHEF  (Institute for High
X    Energy and Nuclear  Physics) in the  Netherlands. She is  the author of
X    The PostScript Chaos  Programs, which draw  Julia sets, Mandelbrot sets
X    and other kinds of fractal functions.

Note: This is a major re-organization (and replacement) of my
"Frequently Asked Questions About X386" FAQ list.
This article includes answers to:
I) What options do I have for X software on my Intel-based Unix system?
1. Free options
2. Commercial options
II) What is XFree86 and where do I get it?
3. What is XFree86?
4. What OSs are supported?
5. What video hardware is supported?
6. What about accelerated boards?
7. Why doesn't XFree86 support 16-color VGA modes?
8. What other hardware or software requirements are there?
9. Where can I get source for XFree86?
10. Where can I get binaries for XFree86?
IV) What general things should I know about running XFree86?
11. Installation directories
12. Configuration files
13. Determining VGA dot clocks and monitor modes
14. Rebuilding/reconfiguring the server from the link kit
V) What OS-specific things should I know about running XFree86?
15. SVR4
16. SVR3
17. 386BSD
18. Linux
19. Mach
VI) What things should I know for building XFree86 from source?
VII) Is there anything special about building clients with XFree86?
20. BSD compatibility library
21. ANSICCOPTIONS
This article does NOT include answers to general X questions, since these
are already covered by the X FAQ that is regularly posted by David B. Lewis
<faq%craft@uunet.uu.net>.
If you have anything to add or change on the FAQ just let me know.
(especially if you had a problem that someone else was able to help you with)
Send changes to steve@ecf.toronto.edu, please put 'FAQ' somewhere
in the subject line so that my mail filter will put it in the correct
mail folder.
Please DO NOT ask me questions that are not answered in the FAQ.  I do not
have time to respond to these individually.  Instead, post your question
to the net, and send me the question and answer together when you get it.
Frequently Asked Questions About X on Intel-based Unix (with answers)
=====================================================================
I) What options do I have for X software on my Intel-based Unix system?
1. Free options
The BEST option is XFree86, which is an enhanced version of X386 1.2.
Any other version of X386 will have slower performance, and will
be more difficult to compile.  Information on how to obtain XFree86
is listed below.
X386 is the port of the X11 server to System V/386 that was
done by Thomas Roell (roell@sgcs.com).
It supports a wide variety of SVGA boards.
There are 2 major free versions: X386 1.1 is based on X11R4,
X386 1.2 is included in MIT's X11R5 distribution (ie. you
don't need to patch it into the MIT source any more).
X386 1.3 is the current commercial offering from SGCS (see below).

II) What is XFree86 and where do I get it?
3. What is XFree86?
XFree86 is an enhanced version of X386 1.2, which was distributed with
X11R5.  This release consists of many bug fixes, speed improvements, and
other enhancements.  Here are the highlights of the enhancements:
1) The SpeedUp package from Glenn Lai is an integral part of XFree86,
selectable at run-time via the Xconfig file.  Some SpeedUps require
an ET4000 based SVGA, and others require a virtual screen width of
1024.  The SpeedUps suitable to the configuration are selected by
default.  With a high-quality ET4000 board (VRAM), this can yield
up to 40% improvement of the xStones benchmark over X386 1.2.
2) The fX386 packages from Jim Tsillas are included as the default
operating mode if SpeedUp is not selected.  This mode is now
equivalent in performance to X386 1.1b (X11R4), and approximately
20% faster than X386 1.2.
3) Support for LOCALCONN, compile-time selectable for server, clients,
or both.  This support is for both SVR3.2 and SVR4.  For SVR4.0.4
with the 'Advanced Compatibility Package', local connections from
SCO XSight/ODT clients are supported.
4) Drivers for ATI and Trident TVGA8900C and TVGA9000 SVGA chipsets.
Refer to the files README.ati and README.trident for details about
the ATI and Trident drivers.
5) Support for compressed bitmap fonts has been added (Thomas Eberhardt's
code from the contrib directory on export.lcs.mit.edu).
6) Type1 Font code from MIT contrib tape has been included, and is
compile-time selectable.  There are contributed Type1 fonts in the
contrib directory on export.lcs.mit.edu.
7) New configuration method which allows the server's drivers and font
renderers to be reconfigured from both source and binary
distributions.
8) Integrated support for 386BSD, Mach, and Linux.
9) A monochrome version of the server which will run on generic VGA
cards is now included.
The following key features were added with the release of XFree86 1.2
(they were not in XFree86 1.1):
1) The monochrome server has been enhanced to do bank-switching of
available SVGA memory to allow virtual screens up to 1600x1200
(see the X386(1) manual page for more information).
2) Support for the Hercules mono card has been added to the
monochrome server, and with it the ability to support a "two
headed" server - one VGA, and one Hercules.  So far this has only
been tested on SVR4 (it is also reported to work under Linux).
3) SVR3 shared libraries, tested under ISC SVR3 2.2 and 3.0.1.
4) Support for SVR4.2 (There are some special considerations to
consider, due to new USL bugs; see the README.SVR4 file for
more information.)
5) Support for PS/2 mice, and Logitech MouseMan/TrackMan (some
versions of these devices were not previously compatible).
6) A new tutorial on how to develop correct video card and monitor
timing data, written by Eric Raymond (derived from previous
documentation and a lot of experimentation).
7) Greatly improved support for international keyboards, including
implementation of the Compose key functionality found on many
vendor servers (see the X386keybd(1) manual page for more
information).
8) The accuracy with which the server detects SVGA pixel clocks has
been improved, and the timings are now stored at accuracies of
0.1 MHz.  Users may want to consider removing an existing Clocks
line from their Xconfig file and re-probing using the new server.
9) Many enhancements in error handling and parsing of the Xconfig
configuration file.  Error messages are much more informative
and intuitive, and more validation is done.  There are many new
options that can be enabled in the Xconfig file (see the X386(1)
manual page for more information on the format of this file).
Plus a number of other small things.  Refer to the CHANGELOG file
in the source distribution for full details.
Also included are a tutorial on monitor timing by Eric Raymond, and the
current X386 mode database and a sample xdm configuration by David Wexelblat.
4. What OSs are supported?
XFree86 supports:
SVR4.2: Consensys V4.2
SVR4.0: Microport, Dell, Esix, ISC, AT&T, MST, Consensys, UHC
SVR3: ISC 2.2 & 3.0, AT&T 2.2
Linux, Mach 386, 386BSD 0.1
BSD/386 is not supported, but it should work. The most active
BSD/386 person is Greg Lehey <grog@lemis.de>.
Note that Esix 3.2D and SCO are not supported yet,
but anyone should feel free to submit patches.
If you are interested in tackling this, send mail to
xfree86@physics.su.oz.au
5. What video hardware is supported?
At this time, XFree86 1.2 supports the following SVGA chipsets:
Tseng ET4000
Tseng ET3000
Paradise PVGA1
Western Digital WD90C00, WD90C10, WD90C11 (these are supersets of
the PVGA1, and use its driver)
Genoa GVGA
Trident TVGA8900C, TVGA9000
ATI 18800, 28800
All of the above are supported in both 256 color and monochrome modes,
with the exception of the ATI chipsets, which are only supported in
256 color mode.
The monochrome server also supports generic VGA cards, using 64k of
video memory in a single bank, and the Hercules card.  On the
ET3000, only 64k of video memory is supported for the monochrome
server, and the GVGA has not been tested with more than 64k.
It appears that some of the SVGA card manufacturers are going to
non-traditional mechanisms for selecting pixel-clock frequencies.  To
avoid having to modify the server to accommodate these schemes XFree86
1.2 adds support for using an external program to select the pixel
clock.  This allows programs to be written as new mechanisms are
discovered.  Refer to the README.clkprog file for information on how
these programs work, if you need to write one.  If you do develop such
a program, the XFree86 team would be interested in including it with
future XFree86 releases.
If you are purchasing new hardware for the purpose of using XFree86,
it is suggested that you purchase an ET4000-based board such as the
Orchid ProDesigner IIs.  Avoid recent Diamond boards; XFree86 will not
work with them, because Diamond won't provide programming details.
In fact, the XFree86 project is actively not supporting new Diamond
products, as long as such policies remain in effect.  Contributions
of code will NOT be accepted (because of the potential liabilities).
If you would like to see this change, tell Diamond about it.
Some people have asked if XFree86 would work with local bus or EISA
video cards. Theoretically, the means of communication between the
CPU and the video card is irrelevant to Xfree86 compatibility. It
could be ISA, EISA, or local bus.  What should matter is the chipset
on the video card.  Unfortunately, the developers don't have a lot
of access to EISA or VLB machines, so this is largely an untested
theory.  However, we have yet to see any reports of things not
working on one of these buses and we have several reports of Xfree86
working fine on them.
6. What about accelerated boards?
At this time, there is no support in XFree86 for accelerated boards
like the S3, ATI Ultra (8514/A), TIGA, etc.  This support is available
in commercial products from SGCS and MetroLink (for SVR3 and SVR4).
An S3 server is available for 386BSD and Linux.  Contact
<hasty@netcom.com> for 386BSD or <jon@robots.ox.ac.uk> for Linux.
A beta 8514/A server is available for Linux. Contact <martin@cs.unc.edu>
or <jon@robots.ox.ac.uk>. Note: these servers are NOT part of XFree86.
7. Why doesn't XFree86 support 16-color VGA modes?
The reason that this is not supported is the way VGA implements the
16-color modes.  In 256-color modes, each byte of frame buffer memory
contains 1 pixel.  But the 16-color modes are implemented as bit-
planes.  Each byte of frame- buffer memory contains 1 bit from each
of each of 8 pixels, and there are four such planes.  The MIT frame-
buffer code is not designed to deal with this.  If VGA handled
16-color modes by packing 2 4-bit pixels into each byte, the MIT code
could be modified to support this (or it already may; I'm not sure).
But for the VGA way of doing things, a complete new frame-buffer
implementation is required.  Some beta testers are looking into this,
but nothing is yet available from the project.
8. What other hardware or software requirements are there?
Obviously, a supported SVGA board and OS are required.  To run
X efficiently, 12-16MB of memory should be considered a minimum.
The various binary releases take 10-40MB of disk space, depending
on the OS (e.g. whether or not it supports shared libraries).
To build from sources, at least 80MB of free disk space will
be required, although 120MB should be considered a comfortable
lower bound.
9. Where can I get source for XFree86?
Source patches for the current version (1.2, based on X11R5 PL22
from MIT), are available via anonymous FTP from:
export.lcs.mit.edu (under /contrib/XFree86)
ftp.physics.su.oz.au (under /XFree86)
ftp.win.tue.nl (under /pub/XFree86)
(For the rest of this FAQ, these 3 location will be called $FTP)
Refer to the README file under the specified directory for information
on which files you need to get to build your distribution.
10. Where can I get binaries for XFree86?
Binaries are available via anonymous FTP from:
ftp.physics.su.oz.au		- SVR4 binaries
under /XFree86/SVR4
ftp.win.tue.nl			- SVR4 binaries
under /pub/XFree86/SVR4
ferkel.ucsb.edu			- SVR4 binaries
under /pub/SVR4/XFree86
stasi.bradley.edu		- SVR4 binaries
under /pub/XFree86/SVR4
blancmange.ma.utexas.edu	- SVR3 (ISC) binaries
under /pub/ISC
ftp.prz.tu-berlin.de            - SVR3 (ISC) binaries
under /pub/pc/isc/XFree86
tsx-11.mit.edu			- Linux binaries
under /pub/linux/packages/X11
agate.berkeley.edu		- 386BSD binaries
under /pub/386BSD/0.1-ports/XFree86
ftp.cs.uwm.edu			- Mach binaries
under /i386
Ensure that you are getting XFree86 1.2 - some of these sites may
archive older releases as well.  Each binary distribution will
contain a README file that describes what files you need to take
from the archive, and which compile-time option selections were
made when building the distribution.
IV) What general things should I know about running XFree86?
11. Installation directories
The top-level installation directory is specified by the ProjectRoot
(/usr/X386, by default) variable in config/site.def. Binaries, include
files, and libraries are installed in $ProjectRoot/{bin,include,lib}.
This can be changed when rebuilding from sources, and can be modified
via symbolic links for those OSs that support them. This directory is
nonstandard, and was chosen this way to allow XFree86 to be installed
alongside a commercial/vendor-supplied X implementation.
12. Configuration files
The XFree86 server reads a configuration file ("Xconfig") on startup.
The search path, contents and syntax for this file are documented in
the server manpage, which should be consulted before asking questions.
13. Determining VGA dot clocks and monitor modes
David E Wexelblat (dwex@mtgzfs3.att.com) maintains a database of known
clock settings for VGA cards and monitor settings.
The database is installed in /usr/X386/lib/X11/etc/modeDB.txt, and
is in the source tree under mit/server/ddx/x386/etc. This database is
also available from him (for the latest copy), and is kept on
export.lcs.mit.edu in ~/contrib/X386.modeDB.Z, which is updated
occasionally.  Obtain a copy of this database.  It just might have the
settings you need.  If you create new settings, please send them to
David for inclusion in the database.
If this doesn't help you, the VideoModes.doc (by Eric Raymond) file
with XFree86 contains tutorials on how to come up with these timings.
It may be helpful to start with settings that almost work, and use
this description to get them right.  When you do, send the information
to David Wexelblat for inclusion in the database.
NOTE: The old 'clock.exe' program is not supported any more, and
is completely unnecessary.  If you need to determine dot
clock values for a new board, remove the 'Clocks' line from
your Xconfig file (if present), and start the server.  The
server will probe for clocks itself and print them out.
You can use these values to put a 'Clocks' line into your
Xconfig file, which is not necessary, but will speed up
starting the server in the future.
14. Rebuilding/reconfiguring the server from the link kit
If you have installed the server Binary Link Kit, it is possible to
reconfigure the drivers and font renderers in the server.  This is
fully explained in the README file that is available with the link kit.
V) What OS-specific things should I know about running XFree86?
First of all, the server must be installed suid-root (mode 4755).
15. SVR4
Why won't my xterm run properly?
If your kernel is not built with the consem module, you should define
CONSEM=no in you environment. Otherwise xterm won't run.
csh users should use 'setenv CONSEM no'
The Esix console driver patch 403019 is known to cause keymapping
problems with XFree86.  It recommended that this patch not be
installed.  Alternatively they keymap can be fixed with xmodmap.
16. SVR3
Make sure you look at $FTP/README.ISC, if that's what you are running.
17. 386BSD
Make sure you look at $FTP/README.386BSD.
Also, a separate 386BSD FAQ is maintained by Richard Murphey
<Rich@Rice.edu>.  The latest version should be available in the
file XFree86-1.2-386BSD-FAQ at the following ftp sites:
agate.berkeley.edu:/pub/386BSD/0.1-ports/XFree86-1.2
wuarchive.wustl.edu:/mirrors4/386bsd/0.1-ports/XFree86-1.2
grasp1.univ-lyon1.fr:pub/386BSD/0.1-ports/XFree86-1.2
18. Linux
You must be running Linux 0.97pl4 or greater, and have the 4.1 gcc
jump libraries installed.
Make sure the binaries X386, X386mono, xload and xterm are setuid root.
If your kernel doesn't have TCP support compiled in, you'll have to
run the server as "X -pn". The default startup configuration assumes
that TCP is not available. If it is, change the two files
/usr/X386/bin/startx and /usr/X386/lib/X11/xdm/Xservers, removing the
-pn argument to X386.
Make sure /dev/console is either a link to /dev/tty0 or has the major
number 4, minor number 0. Also note that if /dev/console is not
owned by the user running X, then xconsole and xterm will not permit
console output redirection. Xdm will properly change the owner, but
startx won't.
When running xdm from rc.local, you will need to provide it with
a tty, for example "xdm < /dev/console &".
For more detailed information, please read the file README present
with the distribution on tsx-11.mit.edu.
19. Mach
Make sure you look at $FTP/README.Mach.
VI) What things should I know for building XFree86 from source?
This section has been removed from the FAQ, since it is
fully explained in $FTP/README and the OS-specific READMEs.
Please look at those files for information on building XFree86.
VII) Is there anything special about building clients with XFree86?
20. BSD compatibility library
A lot of clients make use of BSD functions like bcopy(), etc.
The default configuration files are set up to link with libXbsd.a
which contains emulation for bcopy(), bzero(), bcmp(), ffs(), random(),
seed(). A better way of providing the 'b' functions is to include
<X11/Xfuncs.h> in source files that call them.  Xfuncs.h provides macro
definitions for these in terms of the SYSV 'mem' functions.  If you are
linking with a vendor supplied library which calls some of these
functions, then you should link with libXbsd.a
21. ANSICCOPTIONS
This is something that was added to allow a developer to get rid of the
ANSI-ness defined in the default CCOPTIONS without having to rewrite
the entire CCOPTIONS line.  For example, with stock MIT, you'd see
something like
CCOPTIONS="-ansi -O2 -fwritable-strings"
and to get rid of the ANSI-ness, the developer would have to put
CCOPTIONS="-O2 -fwritable-strings"
in his Imakefile.  With this change, you would see a default of
ANSICCOPTIONS="-ansi"
CCOPTIONS="-O2 -fwritable-strings"
and all the developer would have to put in the Imakefile is:
ANSICCOPTIONS=
to get rid of the ANSI-ness (many X clients will die a horrible death
with -ansi).  The effect is even more dramatic in practice, because
CCOPTIONS is actually quite complex.  The other issue is that one must
add 'ANSICCOPTIONS=$(ANSICCOPTIONS)' to a PassCDebugFlags definition.
XFree86 Contact Information

0.  Xt Glossary
----------------------------------------------------------------------
o The Xt Intrinsics implement an object oriented interface to C code
to allow useful graphical components to be created.  Included with
this are classes that provide the base functionality: Object,
RectObj, Core, Composite, Constraint, Shell, OverrideShell, WMShell,
etc.  The terms "Xt" and "Intrinsics" are used interchangeably,
however, they are used very precisely to mean a specific library of the X
window system.  In particular, it does not include the Athena,
Motif, OLIT or any other widget set.  Without further widgets the
Intrinsics are not especially useful.
o A widget refers to a user interface abstraction created via Xt.  The
precise use, is any object that is a subclass of the Core class.  It
is used loosely to refer to anything that is a subclass of the
Object class although these are more accurately called windowless
widgets or gadgets.
o Xlib is the C interface to the X11 protocol.  It is one layer below
the Xt Intrinsics.  Typically a widget uses relatively few Xlib
functions because Xt provides most such services although an
understanding of Xlib helps with problems.

----------------------------------------------------------------------
3.  Why does my application core dump when I use signals/alarms/cthreads?
----------------------------------------------------------------------
In brief, Xlib, Xt and most widget sets have no mutual exclusion for
critical sections.  Any interrupt handler is likely to leave one of
the above libraries in an inconsistent state -- such as all the
appropriate flags not yet set, dangling pointers, in the middle of a
list traversal, etc.  Note that the ANSI C standard points out that
behavior of a signal handler is undefined if the signal handler calls
any function other than signal() itself, so this is not a problem
specific to Xlib and Xt; the POSIX specification mentions other
functions which may be called safely but it may not be assumed that
these functions are called by Xlib or Xt functions.
The only safe way to deal with signals is to set a flag in the
interrupt handler.  This flag later needs to be checked either by a
work procedure or a timeout callback.  It is incorrect to add either
of these in the interrupt handler.  As another note, it is dangerous
to add a work procedure that never finishes.  This effectively
preempts any work procedures previously added and so they will never
be called.  Another option is to open a pipe, tell the event loop
about the read end using XtAppAddInput() and then the signal handler
can write a byte to the write end of the pipe for each signal.
However, this could deadlock your process if the pipe fills up.
Why don't the Intrinsics deal with this problem?  Primarily because it
is supposed to be a portable layer to any hardware and operating
system.   Is that a good enough reason -- I don't think so.
Note: the article in The X Journal 1:4 and the example in O'Reilly
Volume 6 are in error.
----------------------------------------------------------------------
4.  How do I use a different visual than the default?
----------------------------------------------------------------------
This requires a more complicated answer than it should.  A window has
three things that are visual specific -- the visual, colormap and
border pixmap.  All widgets have their own Colormap and BorderPixmap
resource; only shell widgets have Visual resources (another questions
deals with why shells have a Visual).  The default value of these
resources is CopyFromParent which does exactly what it says.  In the
shell widget CopyFromParent gets evalulated as DefaultVisualOfScreen
and DefaultColormapOfScreen.  When any one of the three resources is
not properly set, a BadMatch error occurs when the window is
created.  They are not properly set because each of the values depends
on the visual being used.
How to get this to work?  There are two parts to the answer.  The
first is if you want an application to start with a particular visual
and the second is if you want a particular shell within an application
to start with a different visual.  The second is actually easier
because the basic information you need is available.  The first is a
little harder because you'll need to initialize much of the toolkit
yourself in order to determine the needed information.
/*
* Some sample code to start up an application using something other
* than the default visual.
*
* To compile:
*	cc -g visual.c -o visual -lXaw -lXmu -lXt -lXext -lX11 -lm
*
* To run:
*	./visual -geometry 300x300 -depth 24 -visual StaticColor -fg blue -bg yellow
*
* you need to move the mouse to get the particular visuals colormap
* to install.

----------------------------------------------------------------------
5.  Which visual should an application use?
----------------------------------------------------------------------
This is a point that can be argued about but one opinion is there is
no way for an application to know the appropriate visual -- it has to
be specified by the user.  If you disagree with this then your
application probably falls into the category of always using the
default visual or it is hardware specific and expects some particular
visual such as 24bit TrueColor with an OverlayPlane extension (or some
such).
Why?  No application runs in isolation.  Depending on the way a server
allocates resources I may not always want your application to run in
TrueColor mode if it is going to mess up my other applications.  I may
be very upset if it chooses to run in GreyScale instead of PsuedoColor
or just monochrome.
As an example, on a low end color Sun server there are many different
possible visuals: monochrome, 256 entry colormap, static gray, static
color, and a 3/3/2 TrueColor.  The SGI Iris's offer all the above
plus 12 bit TrueColor, 24 bit TrueColor, an Overlay Plane.
----------------------------------------------------------------------
6.  Why do only Shell widgets have a Visual?
----------------------------------------------------------------------
This is strictly by convention.  It makes it possible for an arbitrary
widget to know that the visual it uses can be found by looking for the
shell widget that is its ancestor and obtaining the visual of that
shell.
A widget can have its own visual resource.  If it does, it must have
its own realize method to use the visual when it calls
XCreateWindow().  You should also make this a resource that can be
obtained with XtGetValues() so other widgets can find it.  A
reasonable value is probably XtNvisual.
----------------------------------------------------------------------
7.  Which visual, depth and colormap do Shells inherit?
----------------------------------------------------------------------
The default value for these resources are set to CopyFromParent.  This
is interpreted as the DefaultColormapOfScreen(), DefaultDepthOfScreen()
and the default visual of the screen if the widget has no parent -- i.e.
it is an applicationShellWidgetClass and the root of your widget tree.
If the parent of the widget is not null, then the shell copies
colormap and depth from its parent and uses CopyFromParent as the
visual.
----------------------------------------------------------------------
8.  I've done all the above and I still get a BadMatch error.  Why?
----------------------------------------------------------------------
Some resource converters improperly cache references.  This was
especially true of X11R3 and earlier versions of Motif.
----------------------------------------------------------------------
9.  Why doesn't my widget get destroyed when I call XtDestroyWidget()?
----------------------------------------------------------------------
See section 2.8 of the Xt specification.
It eventually does get destroyed, just not immediately.  The
Intrinsics destroy a widget in a two-phase process.  First it and all
of its children have a flag set that indicate it is being destroyed.
It is then put on a list of widgets to be destroyed.  This way any
pending X events or further references to that widget can be cleaned
up before the memory is actually freed.  The second phase is then
performed after all callbacks, event handlers, and actions have
completed, before checking for the next X event.  At this point the
list is traversed and each widget's memory is actually free()'d, among
other things.
As some further caveats/trivia, the widgets may be destroyed if the
Intrinsics determine that they have no further references to the
widgets on the list.  If so, then the phase 2 destruction occurs
immediately.  Also, if nested event loops are used, widgets placed on
the destroy list before entering the inner event loop are not
destroyed until returning to the outer event loop.
----------------------------------------------------------------------
10. How do I exit but still execute the DestroyCallbacks?
----------------------------------------------------------------------
The problem is if a simple and entirely reasonable approach to exiting
an application is used, such as calling exit() directly, then a widget
may not have a chance to clean up any external state -- such as open
sockets, temporary files, allocated X resources, etc.  (this code for
simplicity reasons assumes only a single toplevel widget):
Widget
ToplevelGet (gw)
Widget		gw;		/* widget to find toplevel */
{
Widget		top;
for (top = gw; XtParent (top); top = XtParent (top))
/* empty */;
return (top);
}
void
ExitCallback (gw, closure, call_data)
Widget		gw;		/* widget */
XtPointer	closure;	/* data the app specified */
XtPointer	call_data;	/* widget specific data */
{
Widget		toplevel;
toplevel = ToplevelGet (gw);
XtUnmapWidget (toplevel);	/* make it disappear quickly */
XtDestroyWidget (toplevel);
exit (0);
}
One can see that the above code exit's immediately after destroying
the toplevel widget.  The trouble is the phase 2 destruction may never
occur.
This works for most widgets and most applications but will not work
for those widgets that have any external state.  You might think that
since it works now it will always work but remember that part of the
reason an object oriented approach is used is so one can be ignorant
of the implementation details for each widget.  Which means that the
widget may change and someday require that some external state is
cleaned up by the Destroy callbacks.
One alternative is to modify ExitCallback() to set a global flag and
then test for that flag in a private event loop.  However, private
event loops are frowned upon because it tends to encourage sloppy, and
difficult to maintain practices.
Try the following code instead.
#include <X11/Intrinsic.h>
extern Widget ToplevelGet (
#if NeedFunctionPrototypes
Widget		gw
#endif
);
extern Boolean ExitWorkProc (
#if NeedFunctionPrototypes
XtPointer	closure
#endif
);
extern void ExitCallback (
#if NeedFunctionPrototypes
Widget		gw,
XtPointer	closure,
XtPointer	call_data
#endif
);
Widget
ToplevelGet (gw)
Widget		gw;		/* widget to find toplevel */
{
Widget		top;
for (top = gw; XtParent (top); top = XtParent (top))
/* empty */;
return (top);
}
void
ExitCallback (gw, closure, call_data)
Widget		gw;		/* widget */
XtPointer	closure;	/* data the app specified */
XtPointer	call_data;	/* widget specific data */
{
Widget		toplevel;
toplevel = ToplevelGet (gw);
XtUnmapWidget (toplevel);	/* make it disappear quickly */
XtDestroyWidget (toplevel);
XtAppAddWorkProc (XtWidgetToApplicationContext (gw),
ExitWorkProc, (XtPointer) NULL);
}
Boolean
ExitWorkProc (closure)
XtPointer	closure;
{
exit (0);
/*NOTREACHED*/
}
ExitCallback() adds a work procedure that will get called when the
application is next idle -- which happens after all the events are
processed and the destroy callbacks are executed.
----------------------------------------------------------------------
11. How do I resize a Shell widget?
----------------------------------------------------------------------
After it is realized, one doesn't resize a Shell widget.  The proper
thing is to resize the currently managed child of the Shell widget
using XtSetValues().  The geometry change is then propagated to the
Shell which asks the window manager which may or may not allow the
request.  However, the Shell must have the resource
XtNallowShellResize set to True otherwise it will not even ask the
window manager to grant the request and the Shell will not resize.
To change the position of a Shell, use XtSetValues() on the Shell, not
the child, and within the limits of the window manager it should be granted.
----------------------------------------------------------------------
12. Why can't XtAppAddInput() handle files?
----------------------------------------------------------------------
It does, however Unix semantics for when I/O is ready for a file does
not fit most peoples' intuitive model.  In Unix terms a file
descriptor is ready for reading whenever the read() call would not
block, ignoring the setting of optional flags that indicate not to
block.  This works as expected for terminals, sockets and pipes.  For
a file the read() will always return but the return indicates an EOF
-- i.e. no more data.  The result is the code in the Intrinsics always
calls the input handler because it always thinks something is about to
be read.  The culprit is the select() system call or on SYSV based
OS's it is the poll() system call.
How to get around this on a Unix system?  The best approach is to use
another process to check for available input on the file.  Use a pipe
to connect the application with this other process and pass the file
descriptor from the pipe to XtAppAddInput().  A suitable program on
BSD systems is "tail -f filename".
It's rumored that select() on some systems is not _completely_
reliable.  In particular:
- IBM AIX 3.1: this is one where it would work for a while
(several thousand times) and then stop until some other
event woke it up. This seemed to be the result of a race
condition in the Kernel.  IBM claims to have a fix for this.
- Pyramid, doesn't work at all.
- Ultrix (and possibly others where pipes are implemented as
sockets), wasn't completely broken, but although the writing
side wrote in 512 byte blocks the reading side received it
all broken up as if it was being put into the pipe a byte at
a time.  You can waste a lot of time by reading small blocks
(get raound it by detecting the situation and having
select() ignore the pipe for 10 mseconds - by then it had
been given the whole block).
Note that all the above descriptions used Unix terminology such as
read(), file descriptor, pipes, etc.  This is an OS dependent area and
may not be identical on all systems.  However the Intrinsic designers
felt it was a common enough operation that it should be included with
part of the toolkit.  Why they didn't also deal with signals at this
point I don't know.
----------------------------------------------------------------------
13. What good books and magazines are there on Xt?
----------------------------------------------------------------------
I have a favorite that is the definitive reference.  To my perspective
it offers a reasonable introduction but also goes into the full
details of the Intrinsics.  When I started using it I was already
familiar with Xt and the concepts behind it, so newcomers may or may
not find it useful.  I've always found it accurate and complete, which
means its a 1000 pages.
Asente, Paul J., and Swick, Ralph R., "X Window System Toolkit, The
Complete Programmer's Guide and Specification", Digital Press,
1990, ISBN 1-55558-051-3, order number EY-E757E-DP; and by
Prentice-Hall, ISBN 0-13-972191-6. Also available through DEC
Direct at 1-800-DIGITAL.
The other book I commonly recomend to novices is:
Young, Doug. "The X Window System: Applications and Programming with
Xt (Motif Version)," Prentice Hall, 1989 (ISBN 0-13-497074-8).
(ISBN 0-13-972167-3)
And of course O'Reilly has an entire series of manuals on X and Xt.
O'Reilly ordering is 800-998-9938.  In particular, Volume 5 is an Xt
reference done in manual page style.  The 3rd edition is extensively
overhauled and goes far beyond the MIT manual pages.  I'm finding it
very useful.  In particular, the permutted index and references to
other manual pages help a great deal in chasing down related
information.
I read two periodicals, "The X Resource" and the "The X Journal".
These are the only two dealing specifically with X.  "The X Resource"
is published quarterly, by O'Reilly, with one of the issues being the
MIT X Consortium Technical Conference Proceedings.  There is no
advertising.  I've found it informative with pretty good depth.  For
orders, call 1-800-998-9938, or email cathyr@ora.com.  For editorial
matters, email adrian@ora.com.  Table of contents are posted at
math.utah.edu in ~ftp/pub/tex/bib in TeX form and on ftp.uu.net in
~ftp/published/oreilly/xresource in ASCII form.
"The X Journal" is a bimonthly trade rag with lots of advertising.
The articles are informative and oriented toward a less technical
audience.  I read it more to see what's going on then with an
expectation of learning a great deal (but remember, I represent a
fairly small percentage of people).  Also, they have a pretty good
collection of people on the advisory board and as columnists.  Call
(908) 563-9033.

14. What Widgets are available?
----------------------------------------------------------------------
There are three popular widget sets:
Athena	- The set provided with X11.  This is sufficient for most
purposes but is on the ugly side.  Recently, a 3d look is
available for ftp on export.lcs.mit.edu:/contrib/Xaw3d.tar.Z.
Motif	- From OSF available for a license fee and commonly shipped on
many workstation vendors platforms (almost everyone but
Sun).  It looks good and works well but personally I think
it is poorly implemented.
OLIT	- The Open Look Intrinsics Toolkit is a set of widgets
implementing Sun's Open Look specification.  Developed by
AT&T.  I've never used it so can't comment on its quality.
I've heard rumours that it is a pain to actually get.
In addition the following collection of widgets are also available:
Xtra	- a library of widgets for sale from Graphical Software
Technology (310-328-9338).  It includes bar graph, stacked
bar graph, line graph, pie chart, xy plot, hypertext, help,
spreadsheet, and data entry form widgets.  I've never seen
them so I can't comment.
FWF	- The Free Widget Foundation is attempting to collect a set of
freely available widgets.  Included are a Pixmap editor,
FileDialog, and a few others.  The current set of widgets
can be obtained via anonymous ftp from the machine
a.cs.uiuc.edu (128.174.252.1) in the file pub/fwf.shar.Z.
Xcu	- The Cornell University widgets from Gene Dykes.  One of the
early widget sets released.  Provides a nice appearance for
buttons and has a mini command language.  Probably not so
widely used.
Xs	- The Sony widget set.  This was around during R3 days but
seemed to disappear.  It looked like it had promise.
Xw	- The HP widgets.  The precursor to Motif.  Originally written
for R3 there exists diffs to get it to work under R4 & R5.
Again, a pretty good widget set but has more or less died.
The precursor to this was the Xray toolkit which was
originally implemented for X10R4 and apparently provided
much experience for the designers of Xt.
Xo	- A widget set I'm working on.  It's still primitive but you
can give it a try in archive.cis.ohio-state.edu:pub/Xo/*
The following specialized widgets are also available:
Tbl	- Implements a tabular layout of widgets.  Supports Motif
widgets as children.  Part of Wcl.
Plots	- The Athena Plotting widgets (not the Athena widgets).
Contact gnb@bby.oz.au or joe@Athena.MIT.EDU.

15. What alternatives to the Intrinsics are there?
----------------------------------------------------------------------
__________________________________________
Name		Language	Vendor
__________________________________________
Xview		C		Sun
OI		C++		ParcPlace
Interviews	C++		Stanford
Tcl/tk		C		sprite.berkeley.edu
__________________________________________
However much I like C and admire the skill in both designing and
implementing the Intrinsics, hopefully some alternative will develop
in the next 3-5 years that uses an object oriented language.  Keep
your eyes open and expect some change about the same time a language
other than C _starts_ gaining acceptance.
----------------------------------------------------------------------
16. How do I pass a float value to XtSetValues?
----------------------------------------------------------------------
First, what is going wrong is the structure for an Arg is (essentially)
typdef struct
{
String	name;
long	value;
} Arg;
and the code:
Arg	arg;
XtSetArg (arg, "name", 3.2)
expands to
Arg	arg;
arg.name = "name";
arg.value = 3.2;
you can see that with normal C type conversions, the arg.value
gets the integer "3" instead of the floating point value "3.2".  When
the value is copied into the widget resource, the bit pattern is
wildly different than that required for a floating point value.  So,
how to get around this?
The following macro is from the Athena widgets document and I am now
recomending it over the previous suggestions.
#define XtSetFloatArg(arg, n, d) \
if (sizeof(float) > sizeof(XtArgVal)) { \
XtSetArg(arg, n, &(d)); \
} else { \
XtArgVal *ld = (XtArgVal *)&(d); \
XtSetArg(arg, n, *ld); \
}
----------------------------------------------------------------------
17. How do I write a resource converter?
----------------------------------------------------------------------
Courtesy of Rich Thomson (rthomson@dsd.es.com):
The following discussion of resource converters assumes R4 (or R5)
Intrinsics.  Resource converters changed between R3 and R4 to allow
for destructors and caching of converted values.
There are several main types of resource converters:
string to data type
data type to string
data type to data type
i) string to data type
Usually a string to data type converter has a fixed set of strings
that will be converted to data type values.  This is most often
used to map enumerated names to enumerated values:
Name		Value
"True"		1
"False"		0
In this case, the string to data type converter needs to compare
the resource value to the list of fixed strings.  This is most
readily accomplished by the use of the "quark" mechanism of the
resource manager.  The resource value is turned into a quark,
which is a unique representation of the string that fits into a
single word.  Then the resource quark is compared against the
quarks for the fixed strings representing the enumerated values.
If there are many enumerated strings in the converter (or many
converters, each with a small number of enumeration strings), then
a global initialization routine might be used to turn all the
resource strings into quarks.  That way, the first time one of
these converters is used, the strings will be turned into quarks
and held in static variables for use in the next invocation of one
of the converters.
ii) data type to string
This type of converter is slightly easier than the string to data
type converters since the use of quarks isn't necessary.  Instead,
the data type value is simply converted to a string value,
probably by the use of sprintf.
Data type to string converters are useful for applications that
wish to convert an internal data type value into a string so that
they can write out a valid resource specification to a file.  This
mechanism can be used to provide a "snapshot" of application state
into a file.  This snapshot can be used to restore the program to
a known state via the usual X resource database mechanisms.
If you are taking the trouble to write a string to data type
converter, it isn't much extra effort to write the data type to
string converter.  Writing both at the same time helps to ensure
that they are consistent.
iii) data type to data type
This type of converter is used to convert an existing data type
value to another data type.  For instance, an X pixel value can be
converted to an RGB data type that contains separate fields for
red, green and blue.
The type signature for a resource converter is as follows:
typedef Boolean (*XtTypeConverter)(Display *, XrmValuePtr, Cardinal *,
XrmValuePtr, XrmValuePtr, XtPointer *);
Display *dpy;
XrmValuePtr args;
Cardinal *num_args;
XrmValuePtr fromVal;
XrmValuePtr toVal;
XtPointer *converter_data;
When the converter is invoked, the "fromVal" argument points to the source
X resource manager value and the "toVal" argument points to the
destination X resource manager value.  The "converter_data" argument
is an opaque pointer to some converter-specific data that is specified
when the converter is registered.  The "args" and "num_args" arguments
allow extra information to be passed to the converter when it is
invoked.  For instance, the Pixel to RGB structure converter discussed
above would need colormap and visual arguments in which to lookup the
Pixel to obtain the RGB values corresponding to that pixel.
Care must be taken with the "toVal" argument.  An XrmValue has the
following type definition and specifies a size and location for a
converted value:
typedef struct {
unsigned int    size;
caddr_t         addr;
} XrmValue, *XrmValuePtr;
When the converter is invoked, the address may point to a location of
the given size for the converted value or the location can be NULL.
In the former case, the converter should ensure that the size of the
destination area is large enough to handle the converted value.  If
the destination area is not large enough, then the converter should
set the size to the amount of space needed and return False.  The
caller can then ensure that enough space is allocated and reinvoke the
converter.  If the size is large enough, then the converter can simply
copy the converted value into the space given and return True.
If the location is NULL, then the converter can assign the location to
the address of a static variable containing the converted value and
return True.
When writing a group of converters, this code is often repeated and it
becomes convenient to define a macro:
#define DONE(var, type) \
if (toVal->addr) \
{ \
if (toVal->size < sizeof(type)) \
{ \
toVal->size = sizeof(type); \
return False; \
} \
else \
*((type *) toVal->addr) = var; \
} \
else \
toVal->addr = (caddr_t) &var; \
toVal->size = sizeof(type); \
return True;
#define DONESTR(str) \
if (toVal->addr && toVal->size < sizeof(String)) \
{ \
toVal->size = sizeof(String); \
return False; \
} \
else \
toVal->addr = (caddr_t) str; \
toVal->size = sizeof(String); \
return True;
Inside the converter, it is a good idea to perform a little safety
checking on the "num_args" and "args" arguments to ensure that your
converter is being called properly.
Once you have written your converter, you need to register it with the
Intrinsics.  The Intrinsics invokes resource converters when creating
widgets and fetching their resource values from the resource database.
To register a converter with a single application context, use
XtAppSetTypeConverter:
void XtAppSetTypeConverter(context, from, to, converter, args, num_args,
cache, destructor)
XtAppContext context;
String from;
String to;
XtTypeConverter converter;
XtConvertArgList args;
Cardinal num_args;
XtCacheType cache;
XtDestructor destructor;
To register a converter with all application contexts, use
XtSetTypeConverter:
void XtSetTypeConverter(from, to, converter, args, num_args,
cache, destructor)
String from;
String to;
XtTypeConverter converter;
XtConvertArgList args;
Cardinal num_args;
XtCacheType cache;
XtDestructor destructor;
In the R3 Intrinsics, there were the routines XtAppAddConverter and
XtAddConverter; these have been superseded by XtAppSetTypeConverter
and XtSetTypeConverter.  Whenever possible, the newer routines should be
used.
When a converter is registered with the Intrinsics, a "cache" argument
specifies how converted resource values are to be cached:
XtCacheNone		Don't cache any converted values
XtCacheAll		Cache all converted values
XtCacheByDisplay	Cache converted values on a per display basis
Caching converted values that require a round-trip to the server is a
good idea (for instance string to Pixel conversions).
The "destructor" argument is a routine that is invoked then the
resource is destroyed, either because its cached reference count has
been decremented to zero or because the widget owning the value is
being destroyed.  XtDestructor has the following type definition:
typedef void (*XtDestructor)(XtAppContext, XrmValuePtr, XtPointer,
XrmValuePtr, Cardinal *);
XtAppContext context;
XrmValuePtr to;
XtPointer converter_data;
XrmValuePtr args;
Cardinal *num_args;
The destructor is invoked to free any auxiliary storage associated
with the "to" argument, but does not actually free the storage pointed
to by the "to" argument itself (to->addr).  The destructor is passed
the extra arguments that were passed to the converter when the
conversion was performed (for instance, colormap and visual arguments
for the string to Pixel converter since the destructor would need to
free the allocated Pixel from the colormap) as well as the private
data passed in when the converter was registered.
Sample converter code can be found in the following files in the MIT
R5 distribution:
mit/lib/Xt/Converters.c
contrib/lib/PEXt/Converters.c
contrib/lib/PEXt/Converters.h
----------------------------------------------------------------------
18. How do I open multiple displays?
----------------------------------------------------------------------
See "Multi-user Application Software Using Xt", The X Resource, Issue 3,
(Summer 1992) by Oliver Jones for a complete coverage of the issues
involved.  Most of this answer is based on that article.  In a
nutshell, one uses XtOpenDisplay() to add each display to a _single_
application context and then XtCloseDisplay() to shutdown each display
and remove it from the application context.
The real problems occur when trying to close down a display.  This can
happen 3 ways:
1. User selects a "quit" button on one of the displays,
2. User has window manager send a WM_DELETE_WINDOW message,
3. Server disconnect -- possibly from a KillClient message,
server shutdown/crash, or network failure.
I'll assume you can deal gracefully with 1 & 2 since it is _merely_ a
problem of translating a Widget to a display and removing that
display.  If not, then read the Oliver Jones article.
The third one is difficult to handle.  The following is based on the
Oliver Jones article and I include it here because it is a difficult
problem.
The difficulty arises because the Xlib design presumed that an I/O
error is always unrecoverable and so fatal.  This is essentially true
for a single display X based application, but not true for a
multiple display program or an application that does things other than
display information on an X server.  When an X I/O error occurs the
I/O error handler is called and _if_ it returns then an exit()
happens.  The only way around this is to use setjmp/longjmp to avoid
returning to the I/O error handler.  The following code fragment
demonstrates this:
#include <setjmp.h>
jmp_buf XIOrecover;
void
XIOHandler (dpy)
Display		*dpy;
{
destroyDisplay (dpy);
longjmp (XIOrecover, 1);
}
main ()
{
...
if (setjmp (XIOrecover) == 0)
XSetIOErrorHandler (XIOHandler);
XtAppMainLoop (app_context);
}
The destroyDisplay() is something that given a Display pointer can go
back to the application specific data and perform any necessary
cleanup.  It should also call XtCloseDisplay().
For those of you unfamiliar with setjmp/longjmp, when setjmp() is
first called it returns a 0 and save's enough information in the
jmp_buf that a latter execution of longjmp() can return the program to
the same state as if the setjmp() was just executed.  The return value
of this second setjmp() is the value of the second argument to
longjmp().  There are several caveats about using these but for this
purpose it is adequate.
Some other problems you might run into are resource converters that
improperly cache resources.  The most likely symptoms are Xlib errors
such as BadColor, BadAtom, or BadFont.  There may be problems with the
total number of displays you can open since typically only a limited
number of file descriptors are available with 32 being a typical
value.  You may also run into authorization problems when trying to
connect to a display.
There was much discussion in comp.windows.x about this topic in
November of 91.  Robert Scheifler posted an article which basically
said this is the way it will be and Xlib will not change.
----------------------------------------------------------------------
19. What changed from R3 to R4 to R5?
----------------------------------------------------------------------
This addresses only changes in the Intrinsics.  First, the general
changes for each release are described.  Then a, certainly incomplete,
list of new functions added and others that are now deprecated are
listed.  Brevity is a primary goal.
Much of the following information is retrieved from Chapter 13 of the MIT
Xt Intrinsics Manual and from O'Reilly Volume 5, 3rd edition.
From R3 to R4
- Addition of gadgets (windowless widgets)
- New resource type converter interface to handle cacheing and
additional  data.
- Variable argument list interface.
- #define XtSpecificationRelease 4  (added with this release)
- WMShellPart, TopLevelShellPart & TransientShellPart changed
incompatibly.
- core.initialize, core.set_values added ArgList and count parameters
- event handlers had continue_to_dispatch parameter added
- core.set_values_almost specification changed.
- core.compress_exposure changed to an enumerated data type from Boolean
- core.class_inited changed to enumerated data type from Boolean
- constraint.get_values_hook added to extension record

avoid string copies.  Several fields in the class record are
indicated as needing permanent strings.
- Using an array of Strings for resources

20. Where are the resources loaded from?
----------------------------------------------------------------------
The resources of a widget are filled in from the following places
(from highest priority to lowest priority):
1. Args passed at creation time.
2. Command line arguments.
3. User's per host defaults file
4. User's defaults file.
5. User's per application default file.
6. System wide per application default file.
Note that 2-6 are read only once on application startup.  The result
of steps 3-6 is a single resource database used for further queries.
The per host defaults file contains customizations for all
applications executing on a specific computer.  This file is either
specified with the XENVIRONMENT environment variable or if that is not
set then the file $HOME/.Xdefaults-<host> is used.
The user defaults file is either obtained from the RESOURCE_MANAGER
property on the root window of the display or if that is not set then
the file $HOME/.Xdefaults is used.  Typically, the program "xrdb" is
used to set the RESOURCE_MANAGER property.  Please note that this
should be kept relatively small as each client that connects to the
display must transfer the property.  A size of around 1-3KByte is
reasonable.  Some toolkits may track changes to the RESOURCE_MANAGER
but most do not.
A user may have many per application default files containing
customizations specific to each application.  The intrinsics are quite
flexible on how this file is found.  Read the next part that describes
the various environment variables and how they effect where this file
is found.
The system wide per application default files are typically found in
/usr/lib/X11/app-defaults.  If such a file is not found then the
fallback resources are used.  The intrinsics are quite flexible on how
this file is found.  Read the next part that describes the various
environment variables and how they effect where this file is found.
[Thanks to Oliver Jones (oj@pictel.com) for the following, 6/92]
You can use several environment variables to control how resources are
loaded for your Xt-based programs -- XFILESEARCHPATH,
XUSERFILESEARCHPATH, and XAPPLRESDIR.  These environment variables
control where Xt looks for application-defaults files as an
application is initializing.  Xt loads at most one app-defaults file
from the path defined in XFILESEARCHPATH and another from the path
defined in XUSERFILESEARCHPATH.
Set XFILESEARCHPATH if software is installed on your system in such a
way that app-defaults files appear in several different directory
hierarchies.  Suppose, for example, that you are running Sun's Open
Windows, and you also have some R4 X applications installed in
/usr/lib/X11/app-defaults. You could set a value like this for
XFILESEARCHPATH, and it would cause Xt to look up app-defaults files
in both /usr/lib/X11 and /usr/openwin/lib (or wherever your
OPENWINHOME is located):
setenv XFILESEARCHPATH /usr/lib/X11/%T/%N:$OPENWINHOME/lib/%T/%N
The value of this environment variable is a colon-separated list of
pathnames.  The pathnames contain replacement characters as follows
(see XtResolvePathname()):
%N	The value of the filename parameter, or the
application's class name.
%T	The value of the file "type".  In this case, the
literal string "app-defaults"
%C	customization resource (R5 only)
%S	Suffix.  None for app-defaults.
%L	Language, locale, and codeset (e.g. "ja_JP.EUC")
%l	Language part of %L  (e.g. "ja")
%t	The territory part of the display's language string
%c	The codeset part of the display's language string
Let's take apart the example.  Suppose the application's class name is
"Myterm". Also, suppose Open Windows is installed in /usr/openwin.
(Notice the example omits locale-specific lookup.)
/usr/lib/X11/%T/%N        means /usr/lib/X11/app-defaults/Myterm
$OPENWINHOME/lib/%T/%N    means /usr/openwin/lib/app-defaults/Myterm
As the application initializes, Xt tries to open both of the above
app-defaults files, in the order shown.  As soon as it finds one, it
reads it and uses it, and stops looking for others.  The effect of
this path is to search first in /usr/lib/X11, then in /usr/openwin.
Let's consider another example. This time, let's set
XUSERFILESEARCHPATH so it looks for the file Myterm.ad in the current
working directory, then for Myterm in the directory ~/app-defaults.
setenv XUSERFILESEARCHPATH ./%N.ad:$HOME/app-defaults/%N
The first path in the list expands to ./Myterm.ad.  The second expands
to $HOME/app-defaults/Myterm.  This is a convenient setting for
debugging because it follows the Imake convention of naming the
app-defaults file Myterm.ad in the application's source directory, so
you can run the application from the directory in which you are
working and still have the resources loaded properly.
NOTE: when looking for app-default files with XUSERFILESEARCHPATH,
for some  bizarre reason, neither the type nor file suffix is
defined so %T and %S are useless.
With R5, there's another twist.  You may specify a customization
resource value.  For example, you might run the "myterm" application
like this:
myterm -xrm "*customization: -color"
If one of your pathname specifications had the value
"/usr/lib/X11/app-defaults/%N%C" then the expanded pathname would be
"/usr/lib/X11/app-defaults/Myterm-color" because the %C substitution
character takes on the value of the customization resource.
The default XFILESEARCHPATH, compiled into Xt, is:
/usr/lib/X11/%L/%T/%N%C:\  (R5)
/usr/lib/X11/%l/%T/%N%C:\  (R5)
/usr/lib/X11/%T/%N%C:\     (R5)
/usr/lib/X11/%L/%T/%N:\
/usr/lib/X11/%l/%T/%N:\
/usr/lib/X11/%T/%N
(Note: some sites replace /usr/lib/X11 with a ProjectRoot in this
batch of default settings.)
The default XUSERFILESEARCHPATH, also compiled into Xt, is
<root>/%L/%N%C:\  (R5)
<root>/%l/%N%C:\  (R5)
<root>/%N%C:\     (R5)
<root>/%L/%N:\
<root>/%l/%N:\
<root>/%N:
<root> is either the value of XAPPLRESDIR or the user's home directory
if XAPPLRESDIR is not set.  If you set XUSERFILESEARCHPATH to some
value other than the default, Xt ignores XAPPLRESDIR altogether.
Notice that the quick and dirty way of making your application find
your app-defaults file in your current working directory is to set
XAPPLRESDIR to ".", a single dot.  In R3, all this machinery worked
differently; for R3 compatibilty, many people set their XAPPLRESDIR
value to "./", a dot followed by a slash.

21. What order are callbacks executed in?
----------------------------------------------------------------------
(Courtesy of Donna Converse, converse@expo.lcs.mit.edu; 5/10/92)
The Intrinsics library do not guarantee an order.  This is because
both the widget writer and the application writer have the ability to
modify the entire contents of the callback list.  Neither one
currently knows what the other is doing and so the Intrinsics cannot
guarantee the order of execution.
The application programmer cannot rely on the widget writer; the
widget writer is not required to document when the widget will add and
remove callbacks from the list or what effect this will have;
therefore the functionality contained in a callback should be
independent of the functionality contained in other callbacks on the
list.
Even though the Xt standard in the definition of XtAddCallback
says:
"callback_name: Specifies the callback list to which the
procedure is to be appended."
you may not infer from the word "appended" that the callback routines
are called in the same order as they have been added to the callback
list.
----------------------------------------------------------------------
22. How do I know if a widget is visible?
----------------------------------------------------------------------
(Courtesy of Donna Converse, converse@expo.lcs.mit.edu; 5/14/92)
> I am building a widget needs to know if it is visible. I set the visible

Right, everything is implemented correctly.  This demonstrates a "deficiency"
in the X protocol, and the Core widget is reflecting the capabilities of the
protocol.  (The "deficiency" is that the information is available in one way,
in this case an inconvenient way.)  The Xt specification is accurate, in
the second and third paragraphs of section 7.10.2, so read this section
carefully.  The visible field will not change in response to iconification.
A VisibilityNotify event will not be received when the window goes from
viewable to unviewable, that is, when the widget or an ancestor is unmapped;
that is, when iconification occurs.  This is the protocol deficiency.
Visibility state and viewable state have specific meanings in the X protocol;
see the glossary in your Xlib and X protocol reference manual.
> Is this a problem with "mwm" or is there something
> else which needs to be done?
You'll see this with any window manager, with no window manager.
> If the problem is "mwm", what is the fastest
> way to determine if a window is iconified?
As an application writer, keep track with a global Boolean in an action
routine with translations for MapNotify and UnmapNotify on the Shell widget
which contains your custom widget.  As the custom widget writer, see the
map_state field returned by a call to XGetWindowAttributes.  These are
suggestions.
----------------------------------------------------------------------
23. How do I reparent a widget in Xt, i.e. XtReparentWidget()?
----------------------------------------------------------------------
You can't.
----------------------------------------------------------------------
24. Why use XtMalloc, XtFree, etc?
----------------------------------------------------------------------
Unfortunately, most code that calls malloc(), realloc() or calloc()
tends to ignore the possibility of returning NULL.  At best it is
handled something like:
ptr = (type *) malloc (sizeof (type))
if (!ptr)
{
perror ("malloc in xyzzy()");
exit (1)
}
To handle this common case the Intrinsics define the functions
XtMalloc(), XtCalloc(), XtNew(), XtNewString() and XtRealloc() which
all use the standard C language functions malloc(), calloc() and
realloc() but execute XtErrorMsg() if a NULL value is returned.  Xt
error handlers are not supposed to return so this effectively exits.
In addition, if XtRealloc() is called with a NULL pointer, it uses
XtMalloc() to get the initial space.  This allows code like:
if (!ptr)
ptr = (type *) malloc (sizeof (type));
else
ptr = (type *) realloc (ptr, sizeof (type) * (count + 1));
++count;
to be written as:
ptr = XtRealloc (ptr, sizeof (ptr) * ++count);
Also, XtFree() accepts a NULL pointer as an argument.  Generally, I've
found the Xt functions conveniant to use.  However, anytime I'm
allocating anything potentially large I use the standard functions so
I can fully recover from not enough memory errors.
XtNew() and XtNewString() are conveniant macros for allocating a
structure or copying a string:
struct abc *xyzzy;
char	     *ptr;
char	     *str = "abcdef";
xyzzy = XtNew (struct abc);	/* takes care of type casting */
ptr = XtNewString (str);
A strict interpretation of the Intrinsics reference manual allow an
implementation to provide functions that are not exchangable with
malloc() and free().  I.e. code such as:
char	      *ptr;
ptr = XtMalloc (100);
/* ... */
free (ptr);
may not work.  Personally, I'd call any implementation that did this
broken and complain to the vendor.
A common error for Motif programmers is to use XtFree() on a string
when they should really be using XmStringFree().
----------------------------------------------------------------------
25. How to debug an Xt application?
----------------------------------------------------------------------
First, I'd recomend getting "purify" from Pure Software.  This is a
great package for tracing memory problems on Sun's.  It's a bit pricey
at $2750 but I'd still recomend it.  Excuse the marketing blurb
(contact support@pure.com for more info).
Purify inserts additional checking instructions directly into
the object code produced by existing compilers.  These
instructions check every memory read and write performed by
the program under test and detect several types of access
errors, such as reading unitialized memory, writing past
malloc'd bounds, or writing to freed memory.  Purify inserts
checking logic into all of the code in a program, including
third party and vendor object-code libraries, and verifies
system call interfaces.  In addition, Purify tracks memory
usage and identifies individual memory leaks using a novel
adaption of garbage collection techniques.  Purify's nearly
comprehensive memory access checking slows the target program
down typically by a factor of two to five.
An alternative package that isn't as pricey ($395 for a Sun), runs on
many Unix's and has pretty similar features is "The SENTINEL Debugging
Environment".  This replaces malloc() and several other C library
functions to add additional checks.  (contact cpcahil@virtech.vti.com
for more info)
Next, if you are getting any sort of Xlib error, you'll need to run in
synchronous mode, easily accomplished with the "-sync" command line
argument or by setting the variable Xdebug to 1 with your debugger.  Then
set a break point in exit().  This will let you trace back to the
original Xlib function being called.  If you don't run in synchronous
mode, then the actual error may have occured any number of calls to
Xlib previously since the Xlib calls are buffered and replies from the
server are asynchronous.
Next, if you are having trouble with window layout, you can use the
undocumented resource "xtIdentifyWindows" or the class resource
"XtDebug" to cause the widget name to be identified with each window.
For example:
example% xload -xrm '*XtDebug:true' &
example% xwininfo -tree
<click in new xload window>
will give the normal information but the widget name and class of each
window is included.  This can help for checking the location and size
of errant widgets.
Next, if you are having trouble with geometry managers or you want to
test the way a widget manages it's children, you can try
export.lcs.mit.edu:contrib/libXtGeo.tar.Z.  This acts as a filter
between any children and a geometry manager and checks the behaviour
of both.  It's a very clever idea.
The most unfortunate problem is debugging a callback while the
application is executing a grab of the keyboard or mouse (such as from
a pulldown menu).  The server effectively locks up and you'll need to
go to another machine and kill the debugger manually.  The server
locks up because the application being debugged has said no one else
can have access to the keyboard but the application is not stopped
waiting because the debugger is waiting for your commands.
Unfortunately you can't give them because all the input is going to
your application which is stopped.
The best way to debug this kind of problem is with two machines on
your desk, running the program under a debugger (or other environment)
on one machine, and running the application on the other, possibly
using a command sequence like this:
othermachine% xhost +thismachine
thismachine% setenv DISPLAY othermachine:0;
thismachine% gdb application	# Your favorite debugger.
or this:
othermachine% xhost +thismachine
thismachine% gdb application
(gdb) set environment DISPLAY othermachine:0
(gdb) run ...
I believe CodeCenter, a C interpreter/graphical debugger has a method
of dealing with this by explicitely calling the Xlib functions to
release any grabs during breakpoints.
Debugging widget problems requires pretty good debugging skills and
knowledge of how widgets work.  You can go a long way without knowing
the internals of a particular widget but not very far without
understanding how a widget works.  Judicious use of conditional
breakpoints and adding print statements with the debugger help a great
deal.
----------------------------------------------------------------------
26. Why don't XtAddInput(), XtAddTimeout() and XtAddWorkProc() work?
----------------------------------------------------------------------
I have got a delicate problem with the three routines XtAddInput,
XtAddTimeOut and XtAddWorkProc. The problem I have is that when
I use them in my application they seem not to be registred properly.
I have made a handy little testprogram where everything works
perfect, but in my "real" application nothing happens.
The introduction in R3 of the XtApp*() functions obsoleted those
routines (see Q19 for other changes in R3, R4, and R5).  What happens is
they use a default application context different then the one you may
have created.  Since events and timeouts are distributed on a per
application context basis and you are using two application contexts,
you won't get those events.
For example:
...
cnt = 0;
toplevel = XtAppInitialize(&app, class,
Desc, XtNumber (Desc),
&argc, argv,
Fallback, args, cnt);
XtAddTimeOut (...)
XtAddWorkProc (...)
XtAppMainLoop (app)
would never invoke the timeout.
----------------------------------------------------------------------
27. What is and how can I implement drag and drop?
----------------------------------------------------------------------
(Courtesy of Roger Reynolds, rogerr@netcom.com; 19 Feb 93)
Drag-n-drop is a buzzword for moving data between clients, in an
``intuitive'' fashion.
Motif Version 1.2 supports drag-n-drop capabilities, OpenLook has
supported d-n-d all along.  The two protocols are not compatable with
each other, and so far as I know, they are not published.
I wrote a package called RDD which is designed to be a flexible public
protocol for doing drag 'n drop operations between clients.  My
intention was to provide a tool which would make it easy for people to
support a "standard" drag-n-drop protocol in the programs they develop
and contribute or sell, regardless of what widget set is used (as long
as it is based on Xt).
The implementation is based upon my understanding of the ICCCM
conventions, for more details read the code.
I have heard from dozens of people using RDD who like it and feel that
it works a whole lot better than Motif 1.2 stuff.  Also, there seem to
be many who think that it is neat but are constrained to use Motif
anyway.
The latest RDD (and some other stuff) is available for ftp from
netcom.com, in /pub/rogerr.  A (possibly older) version is also
available on export.lcs.mit.edu in /contrib.

I don't know a great deal about the support for C++ in UIM/X, but I can tell
you that there is good support for it in TeleUSE.  In TeleUSE you can call any
C++ method from a "D" module.  What you can do then is to use the "D" language
for most of your interface code and then use C++ for you application code.
I should tell you that there is some real neat stuff coming out of TeleUSE soon
in regard to C++, but I can't give you many details.  You should talk to your local sales rep and get the lowdown on what they will be doing in the near furture.
If you want example code of how C++ integrates with TeleUSE you should look at
$TeleUSE/examples/Thermometer

Hi,
I'm trying to write a Motif program on an Interactive Unix machine, and I'm
observing very strange behavior when my program attempts to expose a
DrawingArea. Namely, some Xlib operations work, and some do not. In
particular, the expose consist of two XFillRectangle calls followed by some
XDrawPoint calls, and for reasons unknown to me the point calls are failing
whenever a pulldown or popup up menu is (clicked on and) moved in the
rightward direction over the drawing area, but after the move, is still on
some part of the drawing area. This also happens less consistently when the
pulldown/popup is moved in the leftward direction.
Assuming that my code is not doing anything incredibly odd, is this a server
bug?
Thanks,

I have heard of two packages for the PC that support X-Win.
The first is Linux which is a free Unix Package.  The Second
is X-Appeal, which sounds pretty good.  It can be found at
garbo.uwusa.fi in the ~ftp/pc/demo/ dir.  The files are
xap13exe.zip
xap10fon.zip
drivers.zip
This should get you started.

I'm writing 'xwall', a simple X version of 'wall', and I want it to
put a message up on each of a default list of displays.  The problem
is that XOpenDisplay hangs if one of the displays is currently
controlled by xdm (login screen).   I've been through the manuals
and FAQ and don't see a simple way to see if a display is 'openable'
ahead of time, or to get XOpenDisplay to fail after a short period
of time.  Any hints, suggestions, clues, or pointers to info?  Thanks...

I have looked through the FAQ sections and have not
seen a answer for this.
I have an X/Motif application that I have written.
I have a couple of gif files (or pict) that I have
scanned in with a color scanner.  Now I would like
to be able to convert the gif files into a format
that could be read into my application and displayed
on the background of its main window. Preferably with
pixmaps, or perhaps as an XImage.
I have found functions in the pbmplus program suite
to convert gif to xbm, but that is monochrome, and
I really do need color.
I have looked at xv, which reads in gif, and writes
out several formats, but have not found a way to write
out a file which can be read in as a pixmap.
Is there an easy way to do this?
email responses preferred.
thanks!

We have received a number of requests for a reposting of the
International Obfuscated C Code Contest rules and guidelines.  Also
some people requested that these rules be posted to a wider set of
groups.  Sorry for the cross posting.
Some technical clarifications were made to the rules and guidelines
(See the diff marks at the right hand edge).  The rules and guidelines
for this year remain the same, so people who have already or are
in the process of submitting entries for the 1993 IOCCC need not worry
about these changes.

XNOTE: Changes from the 1993 draft are noted by change bars.  --->	      |
X
X
XRULES:
X
X    To help us with the volume of entries, we ask that you follow these rules:
X
X    1) Your entry must be a complete program.
X
X    2) Your entry must be <= 3217 bytes in length.  The number of characters
X       excluding whitespace (tab, space, newline), and excluding any ; { or }
X       followed by either whitespace or end of file, must be <= 1536.
X
X    3) Your entry must be submitted in the following format:
X
X---entry---
Xrule:	1993
Xfix:	y or n   (n => this is a new entry, y => this replaces an older entry)
Xtitle:	title of entry  		    (see comments below)
Xentry:	Entry number from 0 to 7 inclusive  (your 1st entry should by 0)
Xdate:	Date/time of submission in UTC	    (see comments below)
Xhost:	Machine(s) and OS(s) under which your entry was tested
X	Use tab indented lines if needed
X---remark---
X    Place remarks about this entry in this section.  It would be helpful if
X    you were to indent your remarks with 4 spaces, though it is not a
X    requirement.  Also, if possible, try to avoid going beyond the 79th
X    column.  Blank lines are permitted.
X---author---
Xname:	your name
Xorg:	School/Company/Organization
Xaddr:	postal address
X	use tab indented lines to continue
X	don't forget to include the country
Xemail:  Email address from a well known site or registered domain.
X        If you give several forms, list them on separate tab indented lines.
Xanon:	y or n   (y => remain anonymous, n => ok to publish this info)
X---info---
XIf your program needs an info file, place a uuencoded copy of it in
Xthis section.  In the case of multiple info files, use multiple info
Xsections.  If your entry does not need a info file, skip this section.
X---build---
XPlace a uuencoded copy of the command(s) used to compile/build your program
Xin this section.  It must uudecode into a file named 'build'.  The resulting
Xfile must be 255 bytes or less.
X---program---
XPlace a uuencoded copy of your program in this section.  It must uudecode
Xinto a file named is 'prog.c'.  The resulting file must follow rule #2.
X---end---
X
X      Regarding the above format:
X
X	* The title must match the expression: [a-zA-Z0-9_=][a-zA-Z0-9_=+-]*
X	  and must be 1 to 12 characters in length.
X
X	  It is suggested, but not required, that the title should
X	  incorporate your username; in the case of multiple authors,
X	  consider using parts of the usernames of the authors.
X
X	* The date in the ---entry--- section should be given with respect
X	  to UTC.  The format of the date should be as returned by asctime()
X	  using the C locale.  (see guidelines for more info)
X
X	* You may correct/revise a previously submitted entry by sending
X	  it to the contest email address.  Be sure to set 'fix' in the
X	  ---entry--- section to 'n'.  The corrected entry must use the same
X	  title and entry number as submittion that is being corrected.  Be
X	  sure that you note the resubmittion in the ---remark--- as well.
X
X	* With the exception of the header, all text outside of the above
X	  format may be ignored by the judges.  If you need tell the judges
X	  something, put it in the ---remark--- section, or send a separate
X	  Email message to the judges.
X
X	* Information from the ---author--- section will be published unless
X	  'y' was given to the respective author's 'anon' line.
X
X	* To credit multiple authors, include an ---author--- section for
X	  each author.  Each should start with ---author--- line, and
X	  should be found between the ---entry--- and ---build--- sections.
X
X	* The entry's remarks should include:
X	    - what this program does
X	    - how to run the program (sample args or input)
X	    - special compile or execution instructions, if any
X	    - special filename requirements (see rule 4 and 5)
X	    - information about any ---data--- files
X	    - why you think the program is obfuscated
X	    - note if this entry is a re-submission of a previous entry.
X	    - any other remarks (humorous or otherwise)
X
X	* Do not rot13 your entry's remarks.  You may suggest that certain
X	  portions of your remarks be rot13ed if your entry wins an award.
X
X        * Info files should be used only to supplement your entry.  They
X	  should not be required to exist.
X
X	  If your entry does not need an info file, skip the ---info---
X	  section.  If your entry needs multiple info files, use multiple
X	  ---info--- sections, one per info file.  You should describe
X	  each info file in the ---remark--- section.
X
X    4) If your entry is selected as a winner, it will be modified as follows:
X
X	   'build' is incorporated into a makefile, and 'build' is removed
X	   'prog.c' is renamed to your entry's title, followed by an optional
X	       digit, followed by '.c'
X	   your entry is compiled into a file with the name of your entry's
X	       title, possibly followed by a digit
X
X       If your entry requires that a build file exist, state so in your
X       entry's remark section.  The makefile will be arranged to execute a
X       build shell script containing the 'build' information.  The name of
X       this build shell script will be your entry's title, possibly followed
X       by a digit, followed by '.sh'.
X
X       If needed, your entry's remarks should indicate how your entry must
X       be changed in order to deal with the new filenames.
X
X    5) The build file, the source and the resulting executable should be
X       treated as read-only files.  If your entry needs to modify these files,
X       it should make and modify a copy of the appropriate file.  If this
X       occurs, state so in your entry's remarks.
X
X    6) Entries that cannot be compiled by an ANSI C compiler will be rejected.
X       Use of common C (K&R + extensions) is permitted, as long as it does not
X       cause compile errors for ANSI C compilers.
X
X    7) The program must be of original work.  All programs must be in the
X       public domain.  All copyrighted programs will be rejected.
X
X    8) Entries must be received prior to 07-May-93 0:00 UTC.  (UTC is
X       essentially equivalent to Greenwich Mean Time)  Email your entries to:
X
X		...!{apple,pyramid,sun,uunet}!hoptoad!obfuscate
X		obfuscate@toad.com
X
X       We request that your message use the subject 'ioccc entry'.
X
X       If possible, we request that you hold off on Emailing your entries
X       until 1-Mar-93 0:00 UTC.  Early entries will be accepted, however.
X       We will attempt to email a confirmation to the the first author for
X       all entries received after 1-Mar-93 0:00 UTC.
X
X    9) Each person may submit up to 8 entries per contest year.  Each entry
X       must be sent in a separate Email letter.
X
X   10) Entries requiring human interaction to be built are not allowed.
X       Compiling an entry produce a file (or files) which may be executed.
X
X   11) Programs that require special privileges (setuid, setgid, super-user,
X       special owner or group) are not allowed.
X

XABOUT THIS FILE:
X
X    This file is intended to help people who wish to submit entries to
X    the International Obfuscated C Code Contest (IOCCC for short).
X
X    This is not the IOCCC rules, though it does contain comments about
X    them.  The guidelines should be viewed as hints and suggestions.
X    Entries that violate the guidelines but remain within the rules are
X    allowed.  Even so, you are safer if you remain within the guidelines.
X
X    You should read the current IOCCC rules, prior to submitting entries.
X    The rules are typically sent out with these guidelines.
X
X    Changes from the 1993 draft are noted by change bars.  --->		      |
X
X
XWHAT IS NEW IN 1993:
X
X    The entry format is better (for us anyway).  The program mkentry.c
X    has been updated.  See ENTRY FORMAT.
X
X    We will reject entries that cannot be compiled using an ANSI C
X    compiler.  Certain old Obfuscation hacks that cause ANSI C compilers
X    fits are no longer permitted.  Some of the new issues deal with
X    non-integral array types, variable number of arguments, C preprocessor
X    directives and the exit() function.  See OUR LIKES AND DISLIKES.
X
X
XHINTS AND SUGGESTIONS:
X
X    You are encouraged to examine the winners of previous contests.  See
X    FOR MORE INFORMATION for details on how to get previous winners.
X
X    Keep in mind that rules change from year to year, so some winning entries
X    may not be valid entries this year.  What was unique and novel one year
X    might be 'old' the next year.
X
X    An entry is usually examined in a number of ways.  We typically apply
X    a number of tests to an entry:
X
X	* look at the original source
X	* convert ANSI tri-graphs to ASCII
X	* C pre-process the source ignoring '#include' lines
X	* C pre-process the source ignoring '#define' and '#include' lines
X	* run it through a C beautifier
X	* examine the algorithm
X	* lint it
X	* compile it
X	* execute it
X
X    You should consider how your entry looks in each of the above tests.
X    You should ask yourself if your entry remains obscure after it has been
X    'cleaned up' by the C pre-processor and a C beautifier.
X
X    Your entry need not do well under all, or in most tests.  In certain
X    cases, a test is not important.  Entries that compete for the
X    'strangest/most creative source layout' need not do as well as
X    others in terms of their algorithm.  On the other hand, given
X    two such entries, we are more inclined to pick the entry that
X    does something interesting when you run it.
X
X    We try to avoid limiting creativity in our rules.  As such, we leave
X    the contest open for creative rule interpretation.  As in real life
X    programming, interpreting a requirements document or a customer request
X    is important.  For this reason, we often award 'worst abuse of the
X    rules' to an entry that illustrates this point in an ironic way.
X
X    If you do plan to abuse the rules, we suggest that you let us know
X    in the remarks section.  Please note that an invitation to abuse
X    is not an invitation to break.  We are strict when it comes to the
X    3217 byte size limit.  Also, abusing the entry format tends to
X    annoy more than amuse.
X
X    We do realize that there are holes in the rules, and invite entries
X    to attempt to exploit them.  We will award 'worst abuse of the rules'
X    and then plug the hole next year.  Even so, we will attempt to use
X    the smallest plug needed, if not smaller.  :-)
X
X    Check out your program and be sure that it works.  We sometimes make
X    the effort to debug an entry that has a slight problem, particularly
X    in or near the final round.  On the other hand, we have seen some
X    of the best entries fall down because they didn't work.
X
X    We tend to look down on a prime number printer, that claims that
X    16 is a prime number.  If you do have a bug, you are better off
X    documenting it.  Noting "this entry sometimes prints the 4th power
X    of a prime by mistake" would save the above entry.  And sometimes,
X    a strange bug/feature can even help the entry!  Of course, a correctly
X    working entry is best.
X
X
XOUR LIKES AND DISLIKES:
X
X    Doing masses of #defines to obscure the source has become 'old'.  We
X    tend to 'see thru' masses of #defines due to our pre-processor tests
X    that we apply.  Simply abusing #defines or -Dfoo=bar won't go as far
X    as a program that is more well rounded in confusion.
X
X    Many ANSI C compilers dislike the following code, and so do we:
X
X	#define d define
X	#d foo		   <-- don't expect this to turn into #define foo
X
X	int i;
X	j;		   <-- don't use such implicit type declaration
X	int k;
X
X    We suggest that you compile your entry with an ANSI C compiler.  If you
X    must use non-ANSI C, such as K&R C, you must avoid areas that result in
X    compile/link errors for ANSI C compilers.
X
X    Unfortunately, some ANSI C compilers require array indexes to be of       |
X    integral type.  Thus, the following classical obfuscation hacks should    |
X    not be used in 1993.  This rule may be relaxed in future contests.	      |
X
X	int i;
X	char *c;
X	i[c];		   <--- use c[i] instead
X	(i+3)["string"];   <--- use "string"[i+3] instead
X
X    If your entry uses functions that have a variable number of
X    arguments, be careful. Systems implement va_list as a wide variety
X    of ways.  Because of this, a number of operations using va_list are
X    not portable and must not be used:
X
X	* assigning a non-va_list variable to/from a va_list variable
X	* casting a non-va_list variable into/from a va_list variable
X	* passing a va_list variable to a function expecting a non-va_list arg
X	* passing a non-va_list variable to a function expecting a va_list arg
X	* performing arithmetic on va_list variables
X	* using va_list as a structure or union
X
X    In particular, do not treat va_list variables as if they were a char **'s.
X
X    Avoid using <varargs.h>, use <stdarg.h> instead.
X
X    If you use C preprocessor directives (#define, #if, #ifdef, ...),
X    the leading '#' must be the first character on a line.  While some
X    C preprocessors allow whitespace the leading '#', many do not.
X
X    Because the exit() function returns void on some systems, entries
X    must not assume that it returns an int.
X
X    Small programs are best when they are short, obscure and concise.
X    While such programs are not as complex as other winners, they do
X    serve a useful purpose.  They are often the only program that people
X    attempt to completely understand.  For this reason, we look for
X    programs that are compact, and are instructional.
X
X    One line programs should be short one line programs, say around 80
X    bytes long.  Getting close to 160 bytes is a bit too long in our opinion.
X
X    We tend to dislike programs that:
X
X	* are very hardware specific
X	* are very OS or Un*x version specific
X	     (index/strchr differences are ok, but socket/streams specific
X	      code is likely not to be)
X	* dump core or have compiler warnings
X	     (it is ok only if you warn us in the 'remark' header item)
X	* won't compile under both BSD or SYS V Un*x
X	* abusing the build file to get around the size limit
X	* obfuscate by excessive use of ANSI tri-graphs
X	* are longer than they need to be
X	* are similar to previous winners
X	* are identical to previous losers  :-)
X
X    Unless you are cramped for space, or unless you are entering the
X    'best one liner' category, we suggest that you format your program
X    in a more creative way than simply forming excessively long lines.
X
X    The build file should not be used to try and get around the size
X    limit.  It is one thing to make use of a several -D's to help out,
X    but it is quite another to use 200+ bytes of -D's in order to
X    try and squeeze the source under the size limit.  You should feel
X    free to make use of the build file space, but you are better off
X    if you show some amount of restraint.
X
X    We allowed whitespace, and in certain cases ; { or } do not impact
X    your program size (up to a certain point), because we want to get
X    away from source that is simply a compact blob of characters.
X
X    Given two versions of the same program, one that is a compact blob
X    of code, and the other that is formatted more like a typical C
X    program, we tend to favor the second version.  Of course, a third
X    version of the same program that is formatted in an interesting
X    and/or obfuscated way, would definitely win over the first two!
X
X    We suggest that you avoid trying for the 'smallest self-replicating'
X    program.  We are amazed at the many different sizes that claim
X    to be the smallest.  There is nothing wrong with self-replicating
X    programs.  In fact, a number of winners have been self-replicating.
X    You might want to avoid the claim of 'smallest', lest we (or others)
X    know of a smaller one!
X
X    X client entries should be as portable as possible.  Entries that
X    adapt to a wide collection of environments will be favored.  Don't
X    depend on a particular type of display.  For example, don't depend
X    on color or a given size.  Don't require backing store.
X
X    X client entries should avoid using X related libraries and
X    software that is not in wide spread use.  We ask that such X client
X    entries restrict themselves to only the low level Xlib and the
X    Athena widget set (libX11.a, libXaw.a, libXmu.a and libXt.a).
X    Don't use M*tif, Xv*ew, or OpenL*ok toolkits, since not everyone
X    has them.  Avoid depending on a particular window manager.  Not
X    everyone has X11r5, and some people are stuck back in X11r4 (or
X    earlier), so try to target X11r5 without requiring X11r5.  Better
X    yet, try to make your entry run on all version 11 X Window Systems.
X
X    X client entries should not to depend on particular items on
X    .Xdefaults.  If you must do so, be sure to note the required lines
X    in the ---remark--- section.
X
X    We like programs that:
X
X	* are as concise and small as they need to be
X	* do something at least quasi-interesting
X	* pass lint without complaint (not a requirement, but it is nice)
X	* are portable
X	* are unique or novel in their obfuscation style
X	* MAKE USE OF A NUMBER OF DIFFERENT TYPES OF OBFUSCATION
X	* make us laugh and/or throw up  :-)
X
X    Some types of programs can't excel in some areas.  Of course, your
X    program doesn't have to excel in all areas, but doing well in several
X    areas really does help.
X
X    We freely admit that interesting, creative or humorous comments in
X    the ---remark--- section helps your chance of winning.  If you had to
X    read of many twisted entries, you too would enjoy a good laugh or two.
X    We think the readers of the contest winners do as well.
X
X    Be creative!
X
X
XENTRY FORMAT:
X
X    In order to help us process the many entries, we must request your
X    assistance by formatting your entries in a certain way.  This format,
X    in addition, allows us to quickly separate information about the
X    author from the program itself.  (see JUDGING PROCESS)
X
X    We have provided the program, mkentry, as an example of how to
X    format entries.  You should be aware of the following warning that
X    is found in mkentry.c:
X
X	This program attempts to implement the IOCCC rules.  Every
X	attempt has been made to make sure that this program produces
X	an entry that conforms to the contest rules.  In all cases,
X	where this program differs from the contest rules, the
X	contest rules will be used.  Be sure to check with the
X	contest rules before submitting an entry.
X
X    You are not required to use mkentry.  It is convenient, however,
X    as it attempts to uuencode the needed files, and attempt to check
X    the entry against the size rules.
X
X    If you have any suggestions, comments, fixes or complaints about
X    the mkentry.c program, please send Email to the judges.  (see below)
X
X    The following is a sample entry:
X
X---entry---
Xrule:	1993
Xfix:	n
Xtitle:	chonglab
Xentry:	0
Xdate:	Mon Mar  1 08:45:20 1993
Xhost:	Un*x v6, pdp11/45
X	2.9BSD, pdp11/70
X---remark---
X    This is a non-obfuscated obfuscated C program.
X
X    It is likely not to win a prize.  But what do you expect from
X    a short example!

X
X    Typically the build file should assume that the source is prog.c
X    and will compile into prog.  If an entry wins, we will rename
X    its source and binary to avoid filename collision.  By tradition,
X    we use the name of the entry's title, followed by an optional
X    digit in case of name conflicts.
X
X    If the above entry somehow won the 'least likely to win' award,
X    we would use chonglab.c and chonglab.
X
X    If your entry depends on, or requires that your build, source
X    and/or binary files be a particular name, please say so in the
X    ---remark--- section.  If this case applies, it would be be helpful
X    if you did one of the following:
X
X	* Tell us how to change the filename(s) in your entry.
X
X	* Have the build file make copies of the files.  For example:
X
X		cc prog.c -o special_name		need special binary
X
X	    or  rm -f special_src.c			need special source
X		cp prog.c special_src.c
X		cc special_src.c -o special_name
X
X	    or  rm -f special_build			need special build
X		tail +4 build > special_build
X		sh < special_build
X
X	* Assume that we will use the entry title.  Send us a version of
X	  your build/program files that uses the name convention.  You
X	  should uuencode these files in ---data--- sections.
X
X    If your entry needs to modify its source, info or binary files,
X    please say so in the ---remark--- section.  You should try to avoid
X    touching your original build, source and binary files.  You should
X    arrange to make copies of the files you intend to modify.  This
X    will allow people to re-generate your entry from scratch.
X
X    Remember that your entry may be built without a build file.  We
X    typically incorporate the build lines into a Makefile.  If the
X    build file must exist, say so in the ---remark--- section.
X
X    If your entry needs special info files, you should uuencode them
X    into ---info--- sections.  In the case of multiple info files,
X    use multiple ---info--- sections.  If no info files are needed,
X    then skip the ---info--- section.
X
X    Info files are intended to be input, or detailed information that
X    does not fit well into the ---remark--- section.  For example, an
X    entry that implements a compiler might want to provide some sample
X    programs for the user to compile.  An entry might want to include a
X    lengthy design document, that might not be appropriate for a
X    'hints' file.
X
X    Info files should be used only to supplement your entry.  For
X    example, info files may provide sample input or detailed
X    information about your entry.  Because they are supplemental,
X    the entry should not require them exist.
X
X    In some cases, your info files might be renamed to avoid name
X    conflicts.  If info files should not be renamed for some reason,
X    say so in the ---remark--- section.
X
X    Info files must uudecode into the current directory.  If they
X    absolutely must be renamed, or moved into a sub-directory, say
X    so in the ---remark--- section.
X
X    When submitting multiple entries, be sure that each entry has
X    a unique entry number from 0 to 7.  Your first entry should
X    have entry number 0.
X
X    With the exception of the header, all text outside of the entry
X    format may be ignored.  That is, don't place text outside of the
X    entry and expect the judges to see it.  (Our decoding tools aren't
X    AI progs!) If you need tell the the something, put it in the
X    ---remark--- section, or send a Email to the judges at:
X
X	...!{apple,pyramid,sun,uunet}!hoptoad!judges	(not the address for
X	judges@toad.com					 submitting entries)
X
X    The date should be given with respect to UTC.  (Some systems refer
X    to this as GMT or GMT0)  The format of the date should be that as
X    returned by asctime() in the C locale.  An example of such a string is:
X
X	Thr Apr 01 00:47:00 1993
X
X    This format is similar to the output of the date(1) command.  The
X    string does not include the timezone name before the year.  On many
X    systems, one of the following command will produce a similar string:
X
X	date -u "+%a %h %d %T 19%y"
X	date -u | sed -e 's/... \(19[0-9][0-9]\)$/\1/'
X	sh -c 'TZ=UTC date | sed -e "s/... \(19[0-9][0-9]\)$/\1/"'
X	sh -c 'TZ=GMT date | sed -e "s/... \(19[0-9][0-9]\)$/\1/"'
X	sh -c 'TZ=GMT0 date | sed -e "s/... \(19[0-9][0-9]\)$/\1/"'
X
X    You are allowed to update/fix/revise your entry.  To do so, set
X    the 'fix' line in the ---entry--- section to 'y' instead of 'n'.
X    Be sure that the resubmittion uses the same title and entry number
X    as well, as these are used to determine which entry is to be
X    replaced.
X
X
XJUDGING PROCESS:
X
X    Entries are judged by Larry Bassel and Landon Curt Noll.
X
X    Entries are unpacked into individual directories.  The Email message
X    is unpacked into individual files, each containing:
X
X	---entry--- section
X	all ---author--- sections
X	all ---info--- sections
X	---build--- section
X	---program--- section
X	any other text, including the Email message headers
X
X    Prior to judging, the 'any other text' file is scanned to be sure
X    it does not contain useful information (or in case the entry was
X    malformed and did not unpack correctly).  Information from the
X    ---author--- sections are not read until the judging process is
X    complete, and then only from entries that have won an award.
X
X    The above process helps keep us biased for/against any one particular
X    individual.  We are usually kept in the dark as much as you are
X    until the final awards are given.  We like the surprise of finding
X    out in the end, who won and where they were from.
X
X    We attempt to keep all entries anonymous, unless they win an award.
X    Because the main 'prize' of winning is being announced, we make all
X    attempts to send non-winners into oblivion.  We remove all non-winning
X    files, and shred all related paper.  By tradition, we do not even
X    reveal the number of entries that we received.  (for the curious,
X    we do indicate the volume of paper consumed when presenting the IOCCC
X    winners at talks)
X
X    After the Usenix announcement, we attempt to send Email to the
X    authors of the winning entries.  One reason we do this is to give
X    the authors a chance to comment on the way we have presented their
X    entry.  They are given the chance to correct mistakes, typos.  We
X    often accept their suggestions/comments about our remarks as well.
X    This is done prior to posting the winners to the wide world.
X
X    Judging consists of a number of elimination rounds.  During a round,
X    the collection of entries are divided into two roughly equal piles;
X    the pile that advances on to the next round, and the pile that does
X    not.  We also re-examine the entries that were eliminated in the
X    previous round.  Thus, an entry gets at least two readings.
X
X    A reading consists of a number of actions:
X
X	* reading the ---entry--- section
X	* reading the uudecoded ---build--- section
X	* reading the uudecoded ---program--- section
X	* reading the uudecoded ---info--- section(s), if any
X	* passing the source thru the C pre-processor
X	    shipping over any #include files
X	* performing a number of C beautify/cleanup edits on the source
X	* passing the beautified source thru the C pre-processor
X	    shipping over any #include files
X
X    In later rounds, other actions are performed:
X
X	* linting the source
X	* compiling/building the source
X	* running the program
X	* performing misc tests on the source and binary
X
X    Until we reduce the stack of entries down to about 25 entries, entries
X    are judged on an individual basis.  An entry is set aside because it
X    does not, in our opinion, meet the standard established by the round.
X    When the number of entries thins to about 25 entries, we begin to form
X    award categories.  Entries begin to compete with each other for awards.
X    An entry often will compete in several categories.
X
X    The actual award category list will vary depending on the types of entries
X    we receive.  A typical category list might be:
X
X	* best small one line program
X	* best small program
X	* strangest/most creative source layout
X	* most useful obfuscated program
X	* best game that is obfuscated
X	* most creatively obfuscated program
X	* most deceptive C code
X	* best X client (see OUR LIKES AND DISLIKES)
X	* best abuse of ANSI C
X	* worst abuse of the rules
X	* <anything else so strange that it deserves an award>
X
X    We do not limit ourselves to this list.  For example, a few entries are so
X    good/bad that they are declared winners at the start of the final round.
X    We will invent awards categories for them, if necessary.
X
X    In the final round process, we perform the difficult tasks of
X    reducing the remaining entries (typically about 25) down to 8 or 10
X    winners.  Often we are confident that the entries that make it into
X    the final round are definitely better than the ones that do not
X    make it.  The selection of the winners out of the final round, is
X    less clear cut.
X
X    Sometimes a final round entry good enough to win, but is beat out
X    by a similar, but slightly better entry.  For this reason, it is
X    sometimes worthwhile to re-enter an improved version of an entry
X    that failed to win in a previous year.  This assumes, of course,
X    that the entry is worth improving in the first place!
X
X    More often that not, we select a small entry (usually one line), a
X    strange/creative layout entry, and an entry that abuses the contest
X    rules in some way.
X
X    In the end, we traditionally pick one entry as 'best'.  Sometimes such
X    an entry simply far exceeds any of the other entry.  More often, the
X    'best' is picked because it does well in a number of categories.
X
X
XANNOUNCEMENT OF WINNERS:
X
X    The first announcement, occurs at a Summer Usenix conference.  By tradition,
X    this is done during the latter part of the UUNET/IOCCC BOF, just prior to
X    the Berkeley BSD, and BSDI BOF.
X
X    Winning entries will be posted in late June to the following groups:
X
X	    comp.lang.c		  comp.unix.wizards	alt.sources
X
X    In addition, pointers to these postings are posted to the following
X
X	    comp.sources.d	  alt.sources.d		misc.misc
X	    comp.sources.misc	  comp.windows.x
X
X    Winning entries will be deposited into the uunet archives.  See
X    below for details.
X
X    Often, winning entries are published in selected magazines.  Winners
X    have appeared in books ("The New Hackers Dictionary") and on T-Shirts.
X
X    Last, but not least, winners receive international fame and flames!  :-)

We have received a number of requests for a reposting of the
International Obfuscated C Code Contest rules and guidelines.  Also
some people requested that these rules be posted to a wider set of
groups.  Sorry for the cross posting.
Some technical clarifications were made to the rules and guidelines.
(See the diff marks at the right hand edge)  The rules and guidelines
for this year remain the same, so people who have already or are
in the process of submitting entries for the 1993 IOCCC need not worry
about these changes.
