Subject: How does UnpackBits work?
I have been trying to implement UnpackBits in c with mediocre success. As I
understand it, packbits does the following:
Read a byte called control
control < 128?
Next control+1 bytes are straight bitmap
control >= 128?
The next byte in the input stream is repeated 256-control
times
(2s complement of control times)
I am able to read in a file I made that consists of straight lines of bitmap,
however when I have to read a compressed file (a MacPaint file), the routine
gets messed up.
Any code fragments greatly appreciated.

The IBM 360 family was announced in 1963. (Around August--I used to have the
Time Magazine article, but it's gone the way of all paper...) First deliveries
came in early 1964--this was back before anyone could really get away with what
we now know as vaporware.
Granted that Burroughs was using virtual memory long before the 370 series came
out with it, but the 360/67 was a VM machine from about 1966.
This HAS gotten away from the intent of the original question. My original
response was just to demonstrate Adm. Hopper's point: In computing, there is
rarely anything new in the commercial world.

Subject: Re: Fortran linking with C?
I have just gotten my copy of MacTran '77 Version 2.0, and thought I'd
post a few impressions to the net. First of all, this version does
NOT support the 68881 (those are the exact words of the docs, although
it isn't clear whether they mean direct access, although since
MacTran 77 does not use SANE, I think ANY access isn't supported), which
will have to wait for Version 2.01. It appears that version 2.01 will
not run on a 68000, however, but is specifically for the 68020/68881.
MacTran77 features an option for producing .REL files, and linking
with C compiler and assemblers which produce .REL's. The manual
states that the main program must be written in Fortran for linking
to work, although it does not say why. I attempted to get around this
by writing a small Fortran subroutine, compiling it to .REL, and
using LightSpeed C's RelConvert utility. No dice. It bombs with a
cryptic error message. So linking MacTran77 subroutines with LSC
seems to be out.
Since LightSpeed C doesn't produce .REL files yet you can't link the
other way either. This is more than a little frustrating, as it
seems to imply that you must use MPW or Consulair to link with
MacTran.
On the plus side, the toolbox access is decently documented, and
higher level routines are provided.
Has anyone tried linking with Consulair or MPWS?

Subject: Stripped sys/finder
Does anyone have info or a source of info on the method to be used for
stripping down the system and finder files to their smallest possible size?
I seem to recall reading something about the subject here in net-land, but
that's about it. I think it revolves around stripping out particular parts
of the resource forks, but I need to know what I can remove without decreasing
the functionality of the files.

Subject: Giving up on the new systems...
After installing the new systems which have come out of Apple of late,
I am about ready to give up. We used 3.2 fine for months without a
problem, but then when the new systems came in, I thought 'aha!' Just
what we needed! We use, by the way, 2 mac pluses with Hyperdrive 20s,
a Mac plus with an internal Hyperdrive, and a Mac SE with internal Apple
20 meg. Laserwriter on Appletalk, a couple of imagewriters.
Not more than two weeks, problems come creeping out...
1) One of the Hyperdrives refuses to boot -- it claims that it can't
find the Finder, even though both System and Finder are in the
System Folder. Replacing System with good old 3.2 solves the problem.
2) Random, aggravating printer errors.
3) On the SE, cutting while in one application and then pasting in
another (after a trip to the Finder) causes System Error 3.
4) Occasional system errors for no apparent reason.
In short, we have seen enough system errors with this new setup to
open a bomb factory. The new system is already history on the Mac
Pluses, but I would like to know if I can take it off the SE as well.
Any replies would be appreciated.

Subject: Re: More Mac II crashes (V5 #96)
The report is that RedRyder 9.4 and MacKermit 2.2 (2.2? I want 2.2!)
crash on the II because of a subroutine built on the stack that
invalidates the cache.
This is a classic description of a bug in LightSpeed C 2.01.
Apparently it handles PB File Manager calls by builting the trap
on the stack (since there is the rarely-used bit, ASYNC, that is in
the parameter list in C, but in the trap word in assembly language).
Thanks go to Duane Maxwell at Levco (who found it on the Prodigy
before the Mac II was released) for discovering this first.
Think knows about it but didn't seem to think it was serious when
I called a month ago. Perhaps if every owner of Red Ryder called
them up to complain they would change their mind.
In the short run, the only cure seems to be turn off the cache or
recompile using another compiler.

Subject: Patch to Packit III
PackIt III is a great little shareware program written by Harry Chesley.
However, it does have one annoying problem: sometimes the selection lists in
the standard file dialogs are two narrow to distinguish between files that
begin with the same 8 or 10 characters. In these cases, you had to remember
what files were in that directory, alphabetize them mentally, and then count
to the right one. (I thought you never had to remember file names with a
Mac!)
So... I took my trusty copy of ResEdit and modified a few of the DLOGs and
DITLs to alleviate the problem. No more packing in "My Program.proj" when I
wanted "My Program.proj.rsrc". One of the dialogs looks a little strange, but
I find it to be more functional. A Binhex of the new resources follows. To
install, use a resource editor to remove DLOGs 259, 260 and DITLs 270, 271 from
(a copy of) PackIt III and then paste in these replacements.

Subject: My SE and EXCEL
Thanks to all who gave reasons for kermit's poor performance. When
I find a good C compiler I'll recompile it (if someone hasn't by then).
Any preferences?
Now for an EXCEL bug (I think).
I was using EXCEL on my recently purchased MAC SE the other
night. I had a 4 X 3 spread-sheet up. I tried to SAVE it in the usual
fashion. The little watch icon came up indicating that whatever was
happening would take a while so I waited ... and waited ... and waited.
After about 3 minutes or so I began to get the feeling that nothing was
going to happen. The hard drive I was trying to save the sheet on wasn't
moving, no noise, no blinking light, nothing. When I moved the mouse
around the watch icon tracked very nicely. Nothing I did with the
mouse or the keyboard would free up the MAC.
I prayed to the computer gods at that point and cycled the power.
When my machine is idle I keep everything closed and had just RESTARTed
it to open up this sheet for a few minutes so I could add something.
Apparently the order I had done things in kept me safe. When the system
came back up, everything was fine but my spread-sheet had NOT been
updated. I re-entered my date and saved it again. This time it worked.
My system tools disk calls itself version 1.0 and I have EXCEL
version 1.03. Anyone ever notice this behaviour? BTW, just how lucky
was I anyway?
lastly, EXCEL (with a bit of work :-) could be a relational
database as well as a great spread-sheet system. Anyone know if
MicroSoft has any nice plans in this area. (hey MS, are you listening?)

My wife has ~150 Word 3.0 documents on PC. She would like to transfer

is fairly easy to accomplish, however the two versions of Word appear
to be different in some minor respects. In particular, the PC version
uses style sheet entries to get italics and underlining while the Mac
uses some other convention. Needless to say, the conversion does not

Although Word will let you save a document as an ASCII file, when you do this
multiple columns are saved just as they are in the Word file, as one long
column. Does anyone know a way to get around this problem? My only thought
was that maybe someone has written an ASCII file printer driver that would
write printed output to a file.

About 10 days ago I entered a message where I reported about an article

Here's an EDITED synopsis of the responses I got:
From: tj <tj@utorgpu.bitnet>

I have tried a PS800 for a while. QMS is a very reliable company and the PS800
plus should work VERY well for you. It has the same canon engine and a better
version of PostScript and also includes other printer emulations and even an
HP7475 plotter emulation.

From: mead%hamal.usc.edu@oberon.usc.edu (Dick Mead)

I mentioned the article to a co-worker and he says that one problem he has been
hearing is the QMS 800's are prone to lots of mechanical failures, he says
people he knows that use them are always complaining that the unit keeps
breaking down. No details, sorry.
[A further inquiry led to the following message:]
From: Dick <MEAD%hamal@oberon.USC.EDU>
No other info, what I heard was 2nd hand. Don't know the relative age of the
QMS units, but I'd guess they are not too new, as the product itself is not
much over 3-4 years old, at my guess. I bet, like anything else, you can have
lemons or roses, when it comes to how something works..
From: EWING@YALEVM
Yes, I've heard of the QMS Laser printer, and as a matter of fact, we have a
few on this site (Trinity College). Unfortunetely, they were only hooked up to
the Macs that we have for about two weeks last term before we got our real
LaserWriters. Since then the QMSs have been relegated for duty on our AT&T PC
compatibles, where they have served well. When they were attached to our Macs
though, they really shone, and all software didn't know the difference. I
didn't get to test its speed or other general performance against the
LaserWriter, but it seemed to hold its own. And if its got the latest
Postscript driver under the hood, I'd say go for it.

You didn't even mention one of the `nice' features of the 800+: it can do HP
LaserJet emulation... Now for Mac hackers, that's probably not a big deal, but
in a business environment, it is nice. It is faster (we tried one out for a
week) for some things. We hooked one to a Symbolics 3640 were sending large
bitmaps at it (something postscript doesn't do all that well) and it was maybe
twice as fast.I don't have any real interest in QMS, it's just a printer we've
certified as one our products can use (we never even tried hooking it to a mac,
but did to a PC-XT).

says you can use multiple borads! So 6 slots full of MI-4 boards equals about
60 MIPS!
The $1295 MI-4 board contains a 32 bit RISC Transputer, 1MB of RAM, and 4 high-
speed serial communication lines.
There is also a floating-point processing unit for $1495. It is suppose to be
5 times faster than the 68020/68881 pair.
The article also says these boards can be added to a 512 or a Plus. There is
only room for 2 to fit in the cabinet so they offer an expansion box with power
supply and cables for four or more MI-4 borards.
