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]
The MCP (Master Control Program) is the operating system of the Burroughs B5000/B5500/B5700 and the B6500 and successors, including the Unisys Clearpath/MCP systems. MCP was originally written in 1961 in ESPOL (Executive Systems Problem Oriented Language).
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.
The operating system of the System/38 is the Control Program Facility (CPF). CPF is not related to the System Support Program operating system of the IBM System/34 and System/36. CPF objects are files, programs, message queues, user profiles, and libraries.
A PLC is an industrial microprocessor-based controller with programmable memory used to store program instructions and various functions. [21] It consists of: A processor unit (CPU) which interprets inputs, executes the control program stored in memory and sends output signals, A power supply unit which converts AC voltage to DC,
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/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.
Gary Arlen Kildall (/ ˈ k ɪ l d ˌ ɔː l /; May 19, 1942 – July 11, 1994) was an American computer scientist and microcomputer entrepreneur. During the 1970s, Kildall created the CP/M operating system among other operating systems and programming tools, [5] and subsequently founded Digital Research, Inc. to market and sell his software products.
