VM-CP was the official name of the control program portion of VM/370, a re-implementation of CP/CMS for the IBM System/370. It was originally called CP-370. VM/370 was announced in 1972, when virtual memory was added to the System/370 series. A successor of this software is found in today's z/VM. See the article History of CP/CMS for details on the S/370 implementation.

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.
