OS 2200 -an operating system for Unisys mainframes. It runs on systems such as the ClearPath Server OS2200 series (known in the U.S. as the ClearPath Dorado family) of Unisys mainframe computers. Note that BIPROGY refers to it as “OS2200,” while Unisys refers to it as “OS 2200.”
OS2200 is the direct successor to the Exec 8 operating system designed for the UNIVAC 1108. The company at the time was UNIVAC, and the formal name of Exec 8 was “Executive System for the UNIVAC 1108.”
The UNIVAC 1108 was announced in 1964 and released in the latter half of 1965. Although the UNIVAC 1108 initially utilized Exec I and Exec II—which had been developed for the UNIVAC 1107—these systems did not support symmetric multiprocessing for the UNIVAC 1108’s configuration of up to four processors; consequently, UNIVAC planned a version that would enable this capability. By December 1964, the specifications for Exec 8 had been documented in a preliminary programmer’s reference manual (user guide), and the system became operational in March 1965.
Sperry merged with Burroughs to form Unisys. As a result of this history, Unisys’s ClearPath mainframe series employs different operating systems based on the legacy of the two companies: the Sperry-derived OS2200 is used for large-scale systems (such as the ClearPath Server OS2200 and ClearPath IX/2200 series), while the Burroughs-derived MCP is used for medium-scale systems (such as the ClearPath Server MCP and ClearPath NX/LX/A series).
