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 ... -- Yann Droneaud <[EMAIL PROTECTED]> MBDA France Missile Systems -- http://www.mbda.net/ Etudes Logiciels Sol, Bourges Bureau +33 (0) 2 48 55 71 58 | Portable +33 (0) 6 88 40 82 43
