The original model 30 was an 8086, and not even a great one -- it didn't have true VGA, for instance.
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.)
It was also available in a small-form-factor all-in-one case as the Model 25:
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).
Easily mistaken for a PS/1. That got me a lot of abuse on Twitter recently.
The only PS/1 that I've ever seen was a pizza box and had a folding door to cover the 5ΒΌ bay.
They're sort of not "real" PS/2s because they have the AT bus, not MicroChannel. I think the 30-286 could run OS/2 though.
IMHO, it's a PS/2 if it has an IBM PS/2 badge. The PS/2 line covered a LOT of territory.
The same case (or very nearly) was reused for the Model 55SX. I actually have one of these.
I cut my teeth on a 55SX. I may reacquire one some day.
It's a "true" PS/2 with MCA. I hope to get an old version of OS/2 2 or 3 going on mine some time.
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. }:-) -- Grant. . . . unix || die
