VIRTUAL MACHINE SYSTEMS

This section includes virtual machine systems and monitors, and other OSs designed to be used in virtual machine environments.

CMS
Cambridge Monitor System or Conversational Monitor System. Single User Interactive OS developed in conjunction with the Virtual Machine Control Program CP-40 at IBM Cambridge Laboratories. Later adapted for CP-67 and VM/370. Late 1960s [Meyer & Seawright 1970].
CP
Control Program. A component of VM/370 for the IBM/370. CP is the kernel which implements the virtual machine. Early 1970s.
CP-40
Virtual machine control program for a modified IBM 360/40. See also CMS. Mid 1960s [Goldberg 1974].
CP-67
Virtual machine control program for the IBM 360/67. Successor to CP-40. See also CMS. Late 1960s [Meyer & Seawright 1970].
HITAC 8400 OS
A Virtual machine system for the Hitac 8400 (RCA Spectra 70/45). Late 1960s [Goldberg 1974].
IBM 360/30 OS
Virtual machine for the IBM 360/30. Late 1960s [Goldberg 74].
M44/44X
Virtual machine system for modified IBM 7044. An early exploration of virtual machine ideas. Mid 1960s [Goldberg 1974, Belady et al 1981].
Newcastle Recursive VM
Virtual Machine system developed on a Burroughs 1700. Early 1970s [Goldberg 1974].
PDP-10
Virtual machine system for the PDP-10. Early 1970s [Goldberg 1974].
UCLA VM
Virtual machine system developed at UCLA for modified PDP-11/45 for data security studies. Early 1970s [Goldberg 1974].
UMMPS
Virtual machine system for the IBM 360/67. Early 1970s [Goldberg 1974].
VM/370
Virtual machine system for IBM 370. Successor to CP-67. See also CMS. First Release 1972 [IBMSJ 1979, Creasy 1981].
VM/PC
A version of VM/370 for the PC/370. Early 1980s [Daney & Foth 1984].
VOS
Virtual machine OS running on the Michigan Terminal System. Early 1970s [Srodowa & Bates 1973].
