I have OS/2 2.11 (or something like that), it worked (i don't use it any
more ;) very well on my own built PCs (ranging from 486 to Pentium).
I don't remember if OS/2 1.3 worked only on PS/2, but it was the first
release developped without Microsoft, and obviously the first release
that seems to work ;).
Then OS/2 2.0 came with the object oriented GUI: Presentation Manager
(PM).
OS/2 2.11 was able to run Windows 3.11 applications with memory
protection and real multitasking (preemptable).
But until OS/2 3.0 (Warp), it require 8MBytes of RAM, something not
affordable for desktop computing ...
