It was used in academia although it did appear elsewhere for instance in some PLC applications, for a long while some supertankers were running PS/2s with Optio22 I/O boards to control pumps and whatnot.

I have seen the media kits in person recently.  They comically come with an “action” key cap for your Model M.  I have a picture of interested.

I don’t think the lack of popularity was any conspiracy.  SCO had much better ISV and hardware support for PS/2. And if you had a nickel for a real computer there’s a reason the RS/6000 platform and AIX are still around today, it’s not bad stuff despite being a bit different and foreign.

Wow, so the "x86" version of AIX truly existed!

I had long heard rumour of this, and had heard of it from sources I was inclined to trust not to be making it up.  The dates seem to decently explain the invisibility; introduction in 1992 and withdrawal in March 1995 left but a brief period of time when anyone would have been willing to acknowledge it as a product.
