Control Program Facility (CPF) is the operating system of the IBM System/38. [3] CPF represented an independendent line of development at IBM Rochester, and was unrelated to the earlier and more widely used System Support Program operating system. CPF evolved into the OS/400 operating system, which was originally known as XPF (Extended CPF). [1]
IBM Airline Control Program, or ACP, is a discontinued operating system developed by IBM beginning about 1965. In contrast to previous airline transaction processing systems , the most notable aspect of ACP is that it was designed to run on most models of the IBM System/360 mainframe computer family.
CP/M, [3] originally standing for Control Program/Monitor [4] and later Control Program for Microcomputers, [5] [6] [7] is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system [8] and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk.
When Control Data decided to write its next operating system Kronos, it considered both the current SCOPE system and the unofficial MACE alternative. They chose to abandon the SCOPE system and base Kronos on the MACE software. Eventually, Kronos was replaced by the new Network Operating System (NOS). Though many smaller CDC customers continued ...
CP/CMS (Control Program/Cambridge Monitor System) is a discontinued time-sharing operating system of the late 1960s and early 1970s. It is known for its excellent performance and advanced features. It is known for its excellent performance and advanced features.
Most mainframe operating systems terminate a normal application which tries to usurp the operating system's privileges. The VM hypervisor can simulate several types of console terminals for the guest operating system, such as the hardcopy line-mode 3215, the graphical 3270 family, and the integrated console on newer System/390 and System Z ...
In 1961, the MCP was the first OS written exclusively in a high-level language (HLL). The Burroughs Large System (B5000 [2] and successors) were unique in that they were designed with the expectation that all software, including system software, would be written in an HLL rather than in assembly language, which was a unique and innovative approach in 1961.
The System/3 (1969) ran a disk-based batch operating system called the System Control Program (SCP) (5702-SC1). IBM later introduced an online program for the System/3 named the Communications Control Program (CCP) which was started as a batch program. The IBM System/32 (1975) ran a disk-based operating system also called the System Control ...
