PS/1 model 2121 raw backup 1.0
I just recently acquired a PS/1 model 2121, and I thought I'd 'backup' the thing. This backup works with DOS 4.00 (that is in ROM on this thing), and contains everything that was on this PC. I'm sure some of it is corrupt or damaged, but I haven't seen any install sets for the PS/1 . Note the quad screen only works on PS/1's!! *Microsoft Windows 3.0a *Microsoft Works *Microsoft learning windows *Prodigy *PS/1 Club *Promenade *PS/1 System Tutorial And no doubt other incorrectly installed junk.

SCO Unix 3.2 3.2
SCO UNIX System V/386 was the successor to SCO Xenix, derived from AT&T System V Release 3.2 with an infusion of Xenix device drivers and utilities. SCO UNIX System V/386 Release 3.2.0 was released in 1989 as the commercial successor to SCO Xenix. The base operating system did not include TCP/IP networking or X Window System graphics; these were available as optional extra-cost add-on packages. Shortly after the release of this bare OS, SCO shipped an integrated product under the name of SCO Open Desktop, or ODT. 1994 saw the release of SCO MPX, an add-on SMP package.
