Subject: update on my father
Very sorry to inform my father passed away in his sleep peacefully at home last night. His health had been deteriorating of late, and took turn for worse on the weekend. I will circle back around
soon, for now just wanted to give you all advance notice and look forward to discussing your thoughts as I am a bit fuzzy at present.

More info would help - what version, etc.
Josh has one of the more complete archives at http://yahozna.dyndns.org , Steve and Howard are the other "biggies" at
http://www.unixwiz.net/3b2/index.html and http://www.hartetechnologies.com/manuals/3b2/ respectively.
I would love to find more, especially info on the busses and hardware. I have a Version 3 unit that's 1/2-3/4 running and
ineffectually prodded at from time to time, but I could possibly get some stuff off of it.
See below. Please reply directly to Les if you can help.

I will be taking my IBM I/O Selectric and the 360/30 emulator to VCF-GB
this weekend.
This time it's in Coalville, near Leicester:
http://www.silicondreams.org.uk/
You can see video of the Selectric running at
http://www.youtube.com/watch?v=CRdma6NINIw
The 360/30 is running a simple assembler program to print large letters
using a 6x8 matrix. You type in 4 short lines and it echoes them back
in the larger form.
The final printout can be seen at

I have a very nice Altair 8800b for sale. It includes the following S-100
boards:
MITS 8800B CPU BD REV 0
PCC TURNKEY MODULE
PCC S-100 INTERFACE
CEPC 4-SIO-1
The label on back reads:
PCC
Pertec Computer Corporation
Model No. 88-1250
Part No. 200351-05
Serial No. 300-000270
The front panel is in excellent condition. The rest of the case has some
scratches and peeling paint, but is otherwise in very good condition,
typical for its age.
Internally it is in excellent condition, very clean with all parts in
tact. I've never attempted to power up this unit but have no doubt that
it can easily be restored to functional condition.
You can see photos here:

I'm asking $1,200 or best offer.
Please contact me directly for more details.
Thanks!

OK, another story. A friend of mine was a Physics student at
Rolla (University of MO sub-campus) and also very good at
programming/analysis. He had a roommate who was an ME student,
and just learning programming. He saw his professor fiddling
with one of those 15-tile puzzles, and said "Hey, I could
write a program to solve those". His prof said it would be a
good exercise, and gave him an account on the 370/168
at the main campus. He wrote it, and tried it, but it kept
running out of time. He assumed an infinite loop, and eventually
mentioned it to the Physics student. My friend sensed a
teachable moment and said, Hmm, you have 16 nested do loops
>from 1 to 16. Do you know how many total iterations that is?
The guy whips out his trusty HP45 and starts calculating.
My friend smiles, as he already knows that 16^^16 will not
be computable on the calculator. So, they trudge over to
the comp. Sci. building and he shows the guy the System/360
storage and timing estimates book, and they work out that
JUST the loops, themselves, will take something like
10 billion years to complete. He eventually chopped out
useless iterations and got a program that ran in a minute or
so.
So, the moral is that there are relatively modest problems
that can become TOTALLY un-computable with a poor
algorithm. No computer ever made could have finished
his poorly thought out program.

If you are in the Cleveland area, and are interested in old stuff, send me a
list, and I have a recycler who will let me know when they get something in.
They will not hold for more than 2 days before they shred. He does not want
lots of calls from different people, but if I send him a list, he will keep
an eye out for things, and let me know when they come in.

Hi all,
I'm trying to identify the batch setup that I learned programming on.? It was the very first computer I ever used, at Memphis State University in the math department in 1977 or so.? The campus mainframe was a Xerox Sigma-9 time sharing system running CP-V.? There was a computer center in an admin building, and some satellite rooms around campus.? The Math department had a room full of ASR-33's (or ASR35's?), another room containing several Hazeltine 2000's and 1500's and two or three LA36's, and there was a batch room containing several keypunch machines (IBM?), and a batch setup consiting of a card reader the size of a deep freezer, and a page printer.? To run a job, the attendant would stick your fortran cards at the end of an "emulator deck", and run the whole thing through, and the program listing (if requested) and results would print out on the page printer.
Was there such a setup for the Sigma 9?? Or is it likely they had a whole batch minicomputer set up in that room?? I don't remember having to learn anything new about the FORTRAN IV compiler when we graduated to the interactive terminals later in the semester.? For what it's worth, I vaguely remember the hardware being painted brown, or some other earthy color, but then, that memory is nearly 40 years old.
I know it's an odd request, but nostalgia makes you wonder the strangest things.
Thanks,
Dave
