Royal Radar Establishment Automatic Computer
The Royal Radar Establishment Automatic Computer (RREAC) was an early solid-state computer in 1962. It was made with transistors; many of Britain's previous experimental computers used the thermionic valve, also known as a vacuum tube. History Background Britain had built the world's first electronic computer, the Colossus computer, during the war at Bletchley Park in late 1943 and early 1944, and the world's first stored-program computer, the Manchester Baby, on 21 June 1948. The Germans had built the electro-mechanical Z3 in 1941 in Berlin, which used relays. The world's first digital computing device was the Atanasoff–Berry computer in 1942. ENIAC was built in 1946 at the Moore School of Electrical Engineering at the University of Pennsylvania. ENIAC and Colossus both claim to be the world's first electronic computer. Electronic Delay Storage Automatic Calculator (EDSAC) ran its first programs on 6 May 1949 at the University of Cambridge Mathematical Laboratory about a m ...

Solid-state (electronics)
Solid-state electronics are semiconductor electronics: electronic equipment that use semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay, in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD), a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term ''solid-state'' became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of el ...

Geoffrey Dummer
Geoffrey William Arnold Dummer (25 February 1909 – 9 September 2002) was an English electronics engineer and consultant, who is credited as being the first person to popularise the concepts that ultimately led to the development of the integrated circuit, commonly called the microchip, in the late 1940s and early 1950s. Dummer passed the first radar trainers and became a pioneer of reliability engineering at the Telecommunications Research Establishment in Malvern in the 1940s. Dummer studied electrical engineering at Manchester College of Technology starting in the early 1930s. By the early 1940s he was working at the Telecommunications Research Establishment in Malvern (later to become the Royal Radar Establishment). His work with colleagues at TRE led him to the belief that it would be possible to fabricate multiple circuit elements on and into a substance like silicon. In 1952 he became one of the first people to speak publicly on the topic of integrated circuits, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RRE College Of Electronics
The Royal Radar Establishment was a research centre in Malvern, Worcestershire in the United Kingdom. It was formed in 1953 as the Radar Research Establishment by the merger of the Air Ministry's Telecommunications Research Establishment (TRE) and the British Army's Radar Research and Development Establishment (RRDE). It was given its new name after a visit by Queen Elizabeth II in 1957. Both names were abbreviated to RRE. In 1976 the Signals Research and Development Establishment (SRDE), involved in communications research, joined the RRE to form the Royal Signals and Radar Establishment (RSRE). The two groups had been closely associated since before the opening of World War II, when the predecessor to RRDE was formed as a small group within the Air Ministry's research centre in Bawdsey Manor in Suffolk. Forced to leave Bawdsey due to its exposed location on the east coast of England, both groups moved several times before finally settling in separate locations in Malvern begi ...

International Computers Limited
International Computers Limited (ICL) was a British computer hardware, computer software and computer services company that operated from 1968 until 2002. It was formed through a merger of International Computers and Tabulators (ICT), English Electric Computers (EEC) and Elliott Automation in 1968. The company's most successful product line was the ICL 2900 Series range of mainframe computers. In later years, ICL diversified its product line but the bulk of its profits always came from its mainframe customers. New ventures included marketing a range of powerful IBM clones made by Fujitsu, various minicomputer and personal computer ranges and (more successfully) a range of retail point-of-sale equipment and back-office software. Although it had significant sales overseas, ICL's mainframe business was dominated by large contracts from the UK public sector, including Post Office Ltd, the Inland Revenue, the Department for Work and Pensions and the Ministry of Defence (United Kingdo ...

International Computers And Tabulators
International Computers and Tabulators or ICT was a British computer manufacturer, formed in 1959 by a merger of the British Tabulating Machine Company (BTM) and Powers-Samas. In 1963 it acquired the business computer divisions of Ferranti. It exported computers to many countries and in 1968 became part of International Computers Limited (ICL). Products The ICT 1101 was known as the EMIDEC 1100 computer before the acquisition of the EMI Computing Services Division who designed and produced it. The Hollerith Electronic Computer, ICT 1201 computer used vacuum tube, thermionic valve technology and its main memory was Drum memory, drum storage. Input was from 80-column punched cards and output was to 80-column cards and a Line printer, printer. Before the merger, under BTM, this had been known as the HEC4 (Herman Hollerith, Hollerith Electronic Computer, fourth version). The drum memory held 1K of 40-bit words. The computer was programmed using binary machine code instructions. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlas Computer Laboratory
The Atlas Computer Laboratory on the Harwell, Oxfordshire campus shared by the Harwell Laboratory was one of the major computer laboratories in the world, which operated between 1961 and 1975 to provide a service to British scientists at a time when powerful computers were not usually available. The main user population was the UK universities and some government agencies. Now called the Atlas centre, it is home to European Space Agency's (ESA) Business Incubation Centre (ESA BIC), and the Science and Technology Facilities Council's (STFC) Innovations Technology Access Centre (I-TAC). History From 1964 to 1971, the laboratory housed the largest of the three examples of the Ferranti Atlas 1 computer that was purchased for £2.5 million, and after which the laboratory was named. For a time, it was the fastest and most innovative of the computers available worldwide. Throughout its life, it was headed by Jack Howlett. Early staff or visitors included A. O. L. Atkin (1964 ...

Atlas (computer)
The Atlas was one of the world's first supercomputers, in use from 1962 (when it was claimed to be the most powerful computer in the world) to 1972. Atlas's capacity promoted the saying that when it went offline, half of the United Kingdom's computer capacity was lost. It is notable for being the first machine with virtual memory (at that time referred to as "one-level store") using paging techniques; this approach quickly spread, and is now ubiquitous. Atlas was a second-generation computer, using discrete germanium transistors. Atlas was created in a joint development effort among the University of Manchester, Ferranti and Plessey. Two other Atlas machines were built: one for BP and the University of London, and one for the Atlas Computer Laboratory at Chilton near Oxford. A derivative system was built by Ferranti for the University of Cambridge. Called the Titan, or Atlas 2, it had a different memory organisation and ran a time-sharing operating system developed by Camb ...
