is it continued paranoia about getting rid of stuff! > How technical is this manual? I have some

I took another look at the manuals, and one is labeled "Programmer's
Reference Manual" and the other is "Operators Manual." As I browsed
through
the manuals, I didn't see anything relating to the mechanical portions of
the plotter.

New subject: IBM PS-2 model 90 486 available
Does anyone want an IBM PS/2 model 90 XP 486? I have one that needs a
home. It's supposed to work but I haven't tested it. If someone wants it,
I'll check it out. This one has a built-in tape drive. I don't know if
that's standard on the model 90 or not but it certainly looks like it came
from the factory that way. Trades or $$$ welcome.

the tape is an option but has a factory style faceplate, made for certain
models of the PS/2 line - and therefore more expensive then as well. The part
that normally gets yanked on surplus 90's is the 2 cards with clip that form
the 2 RAM banks. as well as the SCSI drive.
What's the tpe number on the right lower fornt of the unit? It will be
something like 8590-xxx or 9590-xxx and the xxx part denotes the processor and
other standard options from the factory. If yyou need the URL to IBM PS/2
harwardware manaul online (HMM) let me know and I'll post it.I have a couple
here in varying states just in case you're overwhelmed with people wanting
90's....

It should all still be in there. It was working and being used when
unplugged it and gave it to me. I haven't opened if but I did notice that
it has what looks like a micro SCSI connector on the back.

It's 8590-0H9. Let me know what that means.

Yes. I'd like to have it.

Actually the ps/2 line uses RS6000 (mini Centronics 60) for SCSI and they tend to
be a little expensive for cables. Even Dalco that had RS6000 cables for $18 went
back to $39 for a 3 ft cable. The 90 is a nice machine for sure if you have a
grasp of MCA over ISA.

8590-0H9 - System Unit 486SX-25, 4MB, 160MB, 1.44, 101 keyboard from the factory
but can be different in some ways due to up/downgrades since it left IBM. The
90's can use the 2.88 floppies too, an PS/2 style keboard or mouse, most SCSI
drives with SCSI I 50 pin ribbon connections. The only real difference is that
the setup/diags are on a hidden 1mb partition (system partition) which is eas to
restore, but makes people craz when they want to use a PS/2 drive set with it for
another machine that doesn't use it, especially for a boot drive. Evidentally the
tape was an after thought addition. It will probabl accept a DC2120 style QIC40
or 80 tape. My guess is an Irwin 250 tape drive.

One of my favorite links for PS/2 stuff is

A collection of links to pages of more detailed info on MCA machines.

Also for anyone interested in what a 90 looks like or specs, go to
