The budget is $80 USD for one or two if lucky!

All PS/2 starts with 85aa-yyy, aa is model number you see on the
oval logo up front, -yyy is type of CPU + speed, number of
floppy(ies), stock capacity of hd installed or none. Stock config
starts with minimum memory so you can not know if some did got
upgraded with larger or smaller HDD, ram upgrades. Complete 85xx-yyy
is on the usually black and white sticker with barcode on back panel.

The list, looking for in order of priority:

Model P75 486 is 486 lunchbox 8573-xxx.
Model 90 XP is 486 desktop 8590-0Jx (486dx 25 w/ cache), -0Kx (486dx
33 w/cache)
Model 70 486 is desktop. 8570-Bxx
Also decent later models of PS/1 based on 486 cpu with ISA. Small
desktop preferred. If you find a desktop of different brands or
models using 486dx chip in small desktops and sign of cache space,
that would be acceptable except for Packard Bells.

I would presume that cracking the cases would be not so practical,
just rely on the model numbers to go by.

Everything else this I listed below are not in my interests at this
moment unless the previous short listing is stated otherwise.

The book I have only listed all the early models between '87 and late
'92 on all: 25/30, 25 SX series, pair of early PS/1 2-386 series,
35 series, 40 SX, L40 SX (thin laptop). All are ISA,
The MCA bus models starts from 50, 50Z, 55 SX/LS, 56 series, 57, 60,
65,70 series, P70 and P75 both are lunchbox, 80 series, 90 XP 486,
95 XP 486 series.

The other info you can explore at your time I have collected so far:

http://www.eagantech.com/scizlist.html - bit of ps/2 info

http://www.can.ibm.com/helpware/vintage.html - some work to look, but
good info but few tidbit info would be nicer!

http://gtweb.net/fPS2guide.html - so so but for fun. :)

http://glycerine.itsmm.uni.edu/mca/models/ - lot of comments, quick
slim tidbits using these machine is related with linux so there. ;)

http://www.computercraft.com/docs/ps2sect.html - cooly tips and THERE
IS info on how to make standard parity memory to work in any PS/2
machines as I explained before! Follow the "The Microchannel
Enthusiast Page" for this.

Joe, might this stuff helps!

:) Great for yours! But my interests is not in that type of
machines AT&T type. Too few around here where I live.
