ah, the 9533! i bought two nonworking ones for $30 and fixed them both! i gave
one to my brother that is still in warranty for two more months. these
machines have 3 year warranty and some are still under warranty. Im having
problems getting a nic to work, but a cute little machine nonetheless. i love
the keyboard too. i have never seen the matching lcd though.

<< > All PS/2 starts with 85aa-yyy,
Not all of them. One of my favorite odd-ball computers is the IBM PS/2e
(9533). It's a very small low-power desktop model with 4 PCMCIA slots.
One of mine even has an external flat panel VGA display. Because of the
low power consumption, I use one as my home LAN internet gateway.
BTW, does anybody have an extra floppy and cable for one of these things?
It uses a notebook floppy drive and a notebook-like cable (mylar?). >>
We are looking to convert a PCjr computer into a serial terminal
emulator, and our limiting factor is finding how to adapting its serial
connector to a DB-9. Has anyone done this? We do not want to spend money
on this, this is a student project. I apoligize for butting into this
list as I can't find how to subscribe, so please reply by personal email.
Also, if anyone knows of a good dos program to use for this project,
please let me know

So many Z-80 CP/M machines... were they compatible, to a reasonable
extent? (I heard that MS had some standard in Japan for the purpose
called MSX. More info on that?)

If you think that's cool, you need to check out what they are doing with QNX:
http://www.qnx.com/iat/createdemo.html
QNX is a very small micro-kernel OS that has the look of Windows 95, has
builtin TCP/IP networking, a notepad, a few other little doodads, and to
top it off, a fully functional HTML 3.2 compliant web browser. Also
supports graphics modes up to 1024x768 in millions of colors.
Okay, not amazing enough for you already? How about if I told you it all
ran off a 1.44mb floppy disk? Hmmmm? :)
Everyone owes to themselves to go grab this FREE (yes, FREE) OS and try it
for themselves.

Yes it was. One of my s100 boxen is a Vector MX (s100 crate only none of
the original boards). The MX was z80 powered byt the Vector 4 may
have been 8088(cpm-86 V1).

Don, I think your right.
The CP/M Version1.0 Release 2 could only be cpm-86 as CP/M-80 would ahve
been more likely 1.4 or 2.2.

At the risk of reviving at least two discussions better left dead, I
have dug out some more IBM documents.
I have a 4361 marketing leaflet - the 4361 was the entry level 370
system between the withdrawal of the 4341/4321 and the introduction of
the 9370. I have practically no technical info so it won't contribute
to the debate on power requirements, but it was a self contained,
air-cooled unit often described as looking like a chest freezer.
I also have the following pocket reference cards/books.
IBM System/34 Command and OCL Statements Reference Summary (9th edition,
April 1983), 170 pages
IBM System/34 COBOL Reference Summary (4th edition, January 1982), 90
pages
IBM System/34 Assembler Reference Summary (3rd edition, July 1979), 26
pages
IBM System/32 SCP Command Statement Reference Summary (6th edition, May
1980), 23 pages
It seems I have a second copy of the Command and OCL statements and
Cobol reference summaries. *** IF ONE OF YOU OUT THERE WITH A SYSTEM/34
NEEDS EITHER OF THESE I WILL SEND IT/THEM TO YOU *** I might also
photocopy the Assembler reference if you ask nicely.
If anyone out there has a System/32 I shall be so amazed I might even
send you my only copy of the reference card.
The instruction set of the System/34 looks CISC and 8-bit-ish, although
it handled 16 bit and (I think) 32 bit data. Typical speed seems to
have been 0.1 to 0.3 MIPS. Someone on this list some months ago
described it as "a room-sized 8088" which is probably about right,
performance-wise...

[Power Consumption of 3090]

All 3090 models are indeed water machines. The 3090 was IBM's large
mainframe of the late 1980s.
There were other 370-derived machines around at the time. In particular
there was the 4300 series, of which the 4361 and 4381 remained at that
time (I think if you tried to buy a 4321 or 4341 you got a 4361. The
price was the same, anyway.) I cannot remember whether these were air
or water cooled, but they were much less powerful than the 3090

I wonder. I have never seen inside the PSU of any of these machines,
but it seems to me that the outputs are all going to be low voltage dc
at a few hundred amps - so conventional switching power supplies could
be contrived (tho' probably not purchased new if there are tens of kW
involved!) to replace the strange 400Hz thingies. And a little circuit
to provide a 400Hz heartbeat if the machine uses this at all...

Yes. Although the elctricity company may do a lot of the work free of
charge if they think you're going to use a lot of the stuff. (My
parents achieved this. They wanted to move the meter board, so the
electrician doing the wiring told the electricity company, they're going
to use so much electricity thy'll need 3-phase and there won't be room
in the existing location. Result: new 3-phase connection and new meter
board, all free of charge.)
> I suppose that is the good thing about RCS/RI - we are in a factory, and

Nice. I'm surprised you don't have this already if you're in a factory.
Here we have 240V (now officially 230V but I've not noticed any change)
single phase up to around 20kW peak demand, 415V 3 phase (now officially
400V, ditto) up to a megawatt or so, 11kV 3 phase above that. Some
factories have their own supply at 33kV or even higher.
