Many years ago, I ran a Fidonet BBS (3:632/392, FWIW). One of the nets I belonged to, Godnet, was run by a guy in New Jersey who used OS/2 to run his PC. Although I eventually ran down an OS/2 box set, I was never able to make it work. All those floppies; some were bound to be bad.
More recently, I acquired an ISO for OS/2 Warp 4.52 and decided to try it out in PCEm.
After finally getting the virtual machine right - it worked! Kinda. 馃捇 馃悞 See attached.
