I always wondered what era the IBM PS/1 is from?
I've seen PS/1
machines but they look 90s. And I never heard of them before the
PS/2, although it would seem logical that the PS/1 came first.
What's the deal?

PS/1s were made from 1990 to 1994. they were consumer models and used
everything between 286-10 to 486-66 cpus. PS/2s were commerical
desktop machines. Most people recognize the PS/1 as one of the first
three models that used 286/386 cpus. they were a proprietary design
with small cases and matching monitors. later models were standard LPX
designs with power management. very simple and easy to fix. I've two
early PS/1s in my collection.

Right. I believe what also distinguished most PS/1s was the "stub"
(shell) built into the ROM. This contained a Quad-screen interface
with 4 choices of programs- MSWorks, Prodigy, DOS, and another
I can't remember. The "stub" could be bypassed and a regular
system installed to replace it. I've got a 2011 ( the monitor section
contained the PSU so the bottom section is useless without it)
The 2021 was similiar. I also have a 2123 and 2133 which had
separate monitors. I believe the 20xx models were 286 while the
21xx could be 386 or 486. It's interesting to note that there were
specific French-Canadian submodels.
