CP-67 is a hypervisor, or Virtual Machine Monitor, from IBM for its System/360 Model 67 computer.
CP-67 is the control program portion of CP/CMS, a virtual machine operating system developed by IBM's Cambridge Scientific Center in Cambridge, Massachusetts. 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.[1]
CP and CMS are usually grouped together as a unit, but the "components are independent of each other. CP-67 can be used on an appropriate configuration without CMS, and CMS can be run on a properly configured System/360 as a single-user system without CP-67."[2]
