The history of operating systems running on IBM mainframes is a notable chapter of history of mainframe operating systems, because of IBM 's long-standing position IBSYS was the tape based Operating system that IBM supplied with its IBM 7090 and This article is about the MIT Computation Center operating system BOS/360 (Basic Operating System/360 was an early IBM Operating system. TOS/360 (Tape Operating System/360 was an IBM Operating system for the System/360, used in the early days around 1965 to support the IBM The IBM Time Sharing System TSS/360 was an early Time-sharing Operating system which ran on a special model of the System/360 line of mainframes the MUSIC/SP (Multi-User System for Interactive Computing / System Product originally "McGill University System for Interactive Computing" was developed at McGill University Michigan Terminal System ( MTS) is an Operating system for the IBM System/360 and its successors that was developed jointly by the following institutions Disk Operating System/360, also DOS/360, or simply DOS, was an Operating system for IBM mainframes It was announced by IBM on the z/VSE (Virtual Storage Extended is an Operating system for IBM mainframe computers the latest one in the DOS/360 lineage, which originated in 1965 See also History of IBM mainframe operating systems OS/360, officially known as IBM System/360 Operating System, was a group of Batch processing In the History of IBM mainframe operating systems, multiprogramming with a fixed number of tasks ( MFT) was one of the three available configurations of the OS/360 Operating System/Virtual Storage 1, or OS/VS1,was an IBM mainframe computer Operating system designed to be run on IBM System/370 Multiple Virtual Storage, more commonly called MVS, was the most commonly used Operating system on the System/370 and System/390 IBM MVS/370 is the earliest currently supported version of the MVS Operating system. MVS/XA, or Multiple Virtual Storage/Extended Architecture, was a version of the IBM operating system that is now called Z/OS. MVS/ESA MVS Enterprise System Architecture Version of MVS, first introduced as MVS/SP Version 3 in February 1988 OS/390 is an IBM Operating system for the System/390 IBM mainframe computers. z/OS is a 64-bit Operating system for Mainframe computers, created by IBM.

Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. It is directly based on technology and concepts dating back to the 1960s, with IBM's CP/CMS on the IBM System/360-67 (see article History of CP/CMS for historical details). CP/CMS was a Time-sharing Operating system of the late 60s and early 70s known for its excellent performance and advanced features System/360|History of CP/CMS|History of IBM The IBM System/360 Model 67 ( S/360-67) was an important IBM mainframe model in the late 1960s.

IBM System z, or earlier IBM eServer zSeries, is a brand name designated by IBM to all its Mainframe computers In 2000 IBM rebranded the existing IBM System z9 is a line of IBM mainframes. It was announced on July 25 2005 and the first models It can be used to support large numbers (thousands) of Linux virtual machines; see Linux on zSeries. Linux on System z is the collective term for the Linux operating system compiled to run on IBM mainframes especially System z machines

Time-sharing refers to sharing a computing resource among many users by multitasking. CP/CMS was a Time-sharing Operating system of the late 60s and early 70s known for its excellent performance and advanced features Many other important systems emerged during this period; cf. Manchester/Ferranti Atlas, Burroughs, Control Data Corporation, DEC, and Honeywell for examples. The Atlas Computer of the University of Manchester, England became operational in 1962 as a joint development between the University Ferranti and Plessey The Burroughs Corporation began in 1886 as the American Arithmometer Company in St Control Data Corporation (CDC, was one of the pioneering Supercomputer firms Honeywell ( is a major American multinational conglomerate company that produces a variety of consumer products engineering services and aerospace systems Also see time-sharing system evolution.
