The IBM AS/400 (Application System/400) is a family of midrange computers from IBM announced in June 1988 and released in August 1988. It was the successor to the System/36 and System/38 platforms, and ran the OS/400 operating system.
The RPG programming language originally was created by IBM for their 1401 systems. IBM later produced implementations for the 7070/72/74 [4] [5] and System/360; [6] RPG II became the primary programming language for their midrange computer product line, (the System/3, System/32, System/34, System/38, System/36 and AS/400).
Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
The first-generation 700s were based on vacuum tubes, while the later, second-generation 7000s used transistors. These machines established IBM's dominance in electronic data processing ("EDP"). IBM had two model categories: one (701, 704, 709, 7030, 7090, 7094, 7040, 7044) for engineering and scientific use, and one (702, 705, 705-II, 705-III ...
IBM CICS (Customer Information Control System) is a family of mixed-language application servers that provide online transaction management and connectivity for applications on IBM mainframe systems under z/OS and z/VSE.
MIT's Fernando Corbató produced the first experimental time-sharing systems, such as CTSS, from 1957 to the early 1960s, using slightly modified IBM 709, [11] [12] IBM 7090, [11] [12] and IBM 7094 [12] mainframes; these systems were based on a proposal by John McCarthy.

The IBM System/3 was an IBM midrange computer introduced in 1969, [1] and marketed until 1985. It was produced by IBM Rochester in Minnesota as a low-end business computer [2] aimed at smaller organizations that still used IBM 1400 series computers or unit record equipment.
