CP-67
From Wikipedia, the free encyclopedia
CP-67 was the control program portion of CP/CMS, a virtual machine operating system developed for the IBM System/360-67 by IBM's Cambridge Scientific Center. It was a reimplementation of their earlier research system CP-40, which ran on a one-off customized S/360-40. CP-67 was later reimplemented (again) as CP-370, which IBM released as VM/370 in 1972, when virtual memory was added to the System/370 series. Details on the development and circumstances of CP-67 can be found in the article History of CP/CMS.

This simplified framework provides links to major time-sharing systems that influenced or were influenced by CP/CMS. Many other important systems emerged during this period; cf. Manchester/Ferranti Atlas, Burroughs, Control Data Corporation, DEC, and Honeywell for examples. Also see time-sharing system evolution.
