OS 2200
OS 2200 is the operating system for the Unisys ClearPath Dorado family of mainframe systems. The operating system kernel of OS 2200 is a lineal descendant of Exec 8 for the UNIVAC 1108. Documentation and other information on current and past Unisys systems can be found on the Unisys public support website.See Unisys 2200 Series system architecture for a description of the machine architecture and its relationship to the OS 2200 operating system.
