English Electric KDF8
KDF8 was an early British computer built by English Electric as a version of the RCA 501. By producing a software-compatible system, the intention was to reduce time and cost to develop software. However, the lengthy process of developing manufacturing capability meant that the system was soon outpaced by systems from other vendors. Only a few systems were sold during its 5 years of production. Due to the consolidation of the British computer industry, English Electric's computer division became one of the components of what would become ICL. Background During the late 1950s English Electric embarked on two major computer projects. Firstly, English Electric built a version of the RCA 501 computer which was known as the KDP10 (KDP for Kidsgrove Data Processing). This was a machine intended for commercial data processing applications, with fixed length instructions, and capabilities for processing variable-length numeric and alpha-numeric data. RCA's original design was adapted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Electric
N.º UIC: 9094 110 1449-3 (Takargo Rail) The English Electric Company Limited (EE) was a British industrial manufacturer formed after the Armistice of 11 November 1918, armistice of World War I by amalgamating five businesses which, during the war, had been making munitions, armaments and aeroplanes. It initially specialised in industrial electric motors and transformers, railway locomotives and traction equipment, diesel motors and steam turbines. Its activities were later expanded to include consumer electronics, nuclear reactors, guided missiles, military aircraft and mainframe computers. Two English Electric aircraft designs became landmarks in British aeronautical engineering; the Canberra and the Lightning. In 1960, English Electric Aircraft (40%) merged with Vickers (40%) and Bristol (20%) to form British Aircraft Corporation. In 1968 English Electric's operations were merged with GEC's, the combined business employing more than 250,000 people. Foundation Aiming ...

Transistor Computer
A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable. A second-generation computer, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation computer. History The University of Manchester's experimental Transistor Computer was first operational in November 1953 and it is widely believed to be the first transistor computer to come into operation anywhere in the world. There were two versions of the Transistor Computer, the prototype, operational in 1953, and the full-size version, commissioned in April 1955. The 1953 machine had 92 point-contact transistors and 550 di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

English Electric System 4
The English Electric (later ICL) System 4 was a mainframe computer announced in 1965. It was derived from the RCA Spectra 70 range, itself a variant of the IBM System 360 architecture. The models in the range included the System 4-10 (cancelled), 4-30 (1967), 4-50 (1967, practically the same as the RCA 70/45), 4-70 (1968, designed by English Electric) and 4-75. ICL documentation also mentions a model 4-40. This was a slugged version of the 4-50, introduced when the 4-30 (intended to be the volume seller) was found to be underpowered and had to be withdrawn. The 4-10 was introduced as a satellite computer, but demand was very low, so it was withdrawn. Only the 4-50 and 4-70, and their successors, the 4-52 and 4-72, sold in any numbers. A slugged 4-72 (the 4-62) was introduced for sale in Eastern Europe. The System 4-50 and 4-70 were intended for real-time applications, for they had four processor states, each with its own set of general-purpose registers A processor regist ...

KDF9
KDF9 was an early British 48-bit computer designed and built by English Electric (which in 1968 was merged into International Computers Limited (ICL)). The first machine came into service in 1964 and the last of 29 machines was decommissioned in 1980 at the National Physical Laboratory. The KDF9 was designed for, and used almost entirely in, the mathematical and scientific processing fields in 1967, nine were in use in UK universities and technical colleges. The KDF8, developed in parallel, was aimed at commercial processing workloads. The KDF9 was an early example of a machine that directly supported multiprogramming, using offsets into its core memory to separate the programs into distinct virtual address spaces. Several operating systems were developed for the platform, including some that provided fully interactive use through PDP-8 machines acting as smart terminal servers. A number of compilers were available, notably both checkout and globally optimizing compilers for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnetic Core Memory
Magnetic-core memory was the predominant form of random-access computer memory for 20 years between about 1955 and 1975. Such memory is often just called core memory, or, informally, core. Core memory uses toroids (rings) of a hard magnetic material (usually a semi-hard ferrite) as transformer cores, where each wire threaded through the core serves as a transformer winding. Two or more wires pass through each core. Magnetic hysteresis allows each of the cores to "remember", or store a state. Each core stores one bit of information. A core can be magnetized in either the clockwise or counter-clockwise direction. The value of the bit stored in a core is zero or one according to the direction of that core's magnetization. Electric current pulses in some of the wires through a core allow the direction of the magnetization in that core to be set in either direction, thus storing a one or a zero. Another wire through each core, the sense wire, is used to detect whether the core ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barclay's Bank
Barclays () is a British multinational universal bank, headquartered in London, England. Barclays operates as two divisions, Barclays UK and Barclays International, supported by a service company, Barclays Execution Services. Barclays traces its origins to the goldsmith banking business established in the City of London in 1690. James Barclay became a partner in the business in 1736. In 1896, twelve banks in London and the English provinces, including Goslings Bank, Backhouse's Bank and Gurney, Peckover and Company, united as a joint-stock bank under the name Barclays and Co. Over the following decades, Barclays expanded to become a nationwide bank. In 1967, Barclays deployed the world's first cash dispenser. Barclays has made numerous corporate acquisitions, including of London, Provincial and South Western Bank in 1918, British Linen Bank in 1919, Mercantile Credit in 1975, the Woolwich in 2000 and the North American operations of Lehman Brothers in 2008.

Kidsgrove
Kidsgrove is a town in the borough of Newcastle-under-Lyme, Staffordshire, England, on the Cheshire border. It is part of the Potteries Urban Area, along with Stoke-on-Trent and Newcastle-under-Lyme. It has a population of 26,276 (2019 census). Most of the town is in the Kidsgrove ward, whilst the western part is in Ravenscliffe. History From the 18th century, Kidsgrove grew around coal mining, although the pits have now closed. Clough Hall Mansion in the town is now demolished. The engineer James Brindley cut the first Harecastle Tunnel on the Trent and Mersey Canal near the town; Thomas Telford cut the second. Kidsgrove also marks the southern extremity of the Macclesfield Canal. There is a legend regarding a headless ghost that is said to haunt the Harecastle Tunnel. The ghost is said to be that of a young woman who was murdered inside the tunnel. She is referred to as the ''"Kidsgrove Boggart"''. R.J. Mitchell, the designer of the Spitfire fighter aircraft, was born in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
