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.

SuperDOS 5.2A
BlueBird SuperDOS is a proprietary multi-tasking multi-user system built to run business applications simultaneously over dumb terminals, replacing expensive mainframe/minicomputers with a single commodity PC. Installation is very complex. It requires "building" the configuration under a DOS environment. You MUST read the manuals. Important: Not all of these disks are formatted for MS-DOS! Opening these disks in WinImage will only show an empty disk. Important: This software is copy protected, it requires a hardware dongle in order to enable multiple users. Archive includes eight 360k 3.5" floppy disk images and eleven 720k 5.25" floppy disk images. This archive includes only the standard double precision program disks, with the exception of Business Basic, which has both.
