I located the following on the 7587 specifically, and
the other URL is
related to all IBM industrials.

All Industrials:

Well not all the industrial machines. The IBM industrial series started with the 553x
machines (XT class) then the 753x machines (AT class) and then the 75xx series of machines
(PS/2 class w/ MCA, 486 chips and upwards into Pentiums and PCI).
I have a number of 7532s (basically a rack mount 5170 w/ beefed up ventilation) and a 7546
(486 PS/2 MCA). However, I have been/am still looking for a 7531 (tower version of the
7532). I had a line on one a few years back but the guy disappeared after his first email
to me...
