SuperDOS 5.2

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.

It was first released around 1983 for 8-bit Z80 IBC/Integrated Business Computers systems, and then IBM PC systems. It grew to support protected mode on 386/486 systems. Although it uses MS/PC-DOS to install, "Protected Mode SuperDOS is a freestanding operating system that is not dependent on either DOS or the ROM BIOS.". Most applications for it are written in BlueBird SuperDOS Business Basic.

Bluebird SuperDOS was originally developed for car rental agencies and moving-and-storage companies that needed workstations at many points for data entry, but did not want to put a powerful and expensive computer on every desk.

Applications produced for it included CPA, Medical Office, Legal Office, Manufacturing, Auto Rental, Van and Storage, Wholesale Distribution, and Word Processing. Most of these were ported from Data General compatible Business Basic software.

Initially it competed with Data General's Business Basic. A similar multi user basic-oriented product was Thoroughbred/OS, and much later Citrix Multiuser attempted to fill a similar role.

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.

This archive includes only the standard double precision program disks, with the exception of Business Basic, which has both.
