Honeywell DPS-6

Mainframes (often colloquially referred to as Big Iron) are computers used mainly by government institutions and large companies for mission critical applications, typically bulk data processing such as census, industry/consumer statistics, ERP, and financial transaction processing. The term originated during the early 1970s with the introduction of smaller, less complex computers such as the DEC PDP-8 and PDP-11 series, which became known as minicomputers (also referred to simply as minis). The industry/users then coined the term "mainframe" to describe larger, earlier types (previously known simply as "computers").

From the 1950's until the mid-1970's, Honeywell was the United States importer of Pentax cameras and photographic equipment. These products were labeled in the U.S. Honeywell Pentax. From 1961 to 1978 the company expanded into such fields as defense, aerospace, computers and cameras. Honeywell originally entered the computer business via a joint venture with Raytheon called Datamatic Corp., but soon bought out Raytheon's share and the business became a Honeywell division. It also purchased minicomputer pioneer Computer Control Corporation, renaming it as Honeywell's Computer Control Division. Through most of the 1960s, Honeywell was one of the "Snow White and the Seven Dwarfs" of computing. IBM was "Snow White," while the dwarfs, in addition to Honeywell, included Burroughs, Control Data Corporation, GE, NCR, RCA, and Univac.

In 1957, Honeywell, along with Ratheon, introduced one of the first computers in the U.S., the Datamatic 1000. Two years later, Honeywell's 800 and 400 models earned a solid reputation for advanced features.In the mid-1960s, Honeywell's 200 series gave IBM serious competition. It outperformed IBM's very successful 1401 computer, which it emulated, causing IBM to accelerate its introduction of its System/360. In 1966, Honeywell acquired Computer Control Company's minicomputer line, and in 1970, it acquired the assets of GE's computer business. The computer division was renamed Honeywell Information Systems, Inc. Through Honeywell's association with Groupe Bull in Europe and Bull's association with NEC in Japan, research and development were mutually explored and products were jointly developed. In the late 1980s, the three companies formed Honeywell Bull, and later Bull acquired the majority interest, renaming the organization Bull HN. The famous Honeywell name, having been identified with the most advanced computers, remained only as the "H" in Bull HN. In 1970, Honeywell bought General Electric's computer division. The company was reorganized into two operating units: Honeywell Information Systems, headed by President Clarence (Clancy) Spangle and headquartered in Waltham, Mass., and Honeywell Control Systems, headed by President Edson Spencer and headquartered in Minneapolis with the corporation's overall HQ. After RCA's sale of its computer business to Univac not long after, the term "Seven Dwarfs" was replaced by "the BUNCH" based on the initials of the five remaining smaller firms: Burroughs, Univac, NCR, Control Data and Honeywell in that order. In 1991 Honeywell's computer division was sold to Groupe Bull.

Our DPS 6 has been deassessioned and shipped to EDF Energy who own and run eight nuclear power stations in the United Kingdom.
