The original IBM PC / AT / XT didn't have VGA either.  So that seems par 
for the generation of the processor.  (At least as I understand / 
remember it.)

I always liked the PS/2 cases.  Just about every one I've seen is tool 
less down to, and sometimes including, the system planar (as IBM called it).

The only PS/1 that I've ever seen was a pizza box and had a folding door 
to cover the 5¼ bay.

IMHO, it's a PS/2 if it has an IBM PS/2 badge.  The PS/2 line covered a 
LOT of territory.

I cut my teeth on a 55SX.  I may reacquire one some day.

I know that I've run OS/2, OS/2 Warp, and Windows 95, all loaded off of 
floppy disks on my model 80 that I had at the time.  I've also had 
NetWare on multiple of them.

I want to try to get AIX 1.3 on the model 70 that I have now.

I'm the masochist that will configure Token Ring for it.  }:-)
