Hollerith Electronic Computer
The Hollerith Electronic Computer (HEC) was produced by the British Tabulating Machine Company (BTM) and was based on a design by Professor Andrew Booth of Birkbeck College, London. It was Britain's first mass-produced business computer. The prototype first worked at the end of 1951. Origins In 1950 John Womersley, who had previously led the team developing the Automatic Computing Engine (ACE) at the National Physical Laboratory (NPL), joined the Unit record equipment company, BTM. He recognised that there was a need for smaller inexpensive computers and recruited Andrew Booth as a consultant to develop such a machine. Booth had previously worked for the British Rayon Research Association (BRRA) before moving to Birkbeck College in 1945. The BRRA had sponsored him to develop what became the All Purpose Electronic Computer (APEXC). He needed punched card input and output technologies and struck a deal with BTM, whereby they supplied him with these in return for their copying ...

Kilobyte
The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix ''kilo'' as 1000 (103); per this definition, one kilobyte is 1000 bytes.International Standard IEC 80000-13 Quantities and Units – Part 13: Information science and technology, International Electrotechnical Commission (2008). The internationally recommended unit symbol for the kilobyte is kB. In some areas of information technology, particularly in reference to solid-state memory capacity, ''kilobyte'' instead typically refers to 1024 (210) bytes. This arises from the prevalence of sizes that are powers of two in modern digital memory architectures, coupled with the accident that 210 differs from 103 by less than 2.5%. A kibibyte is defined by Clause 4 of IEC 80000-13 as 1024 bytes. Definitions and usage Base 10 (1000 bytes) In the International System of Units (SI) the prefix ''kilo'' means 1000 (103); therefore, one kilobyte is 1000 bytes. The u ...

The National Museum Of Computing
The National Museum of Computing is a museum in the United Kingdom dedicated to collecting and restoring historic computer systems. The museum is based in rented premises at Bletchley Park in Milton Keynes, Buckinghamshire and opened in 2007. The building — ''Block H'' — was the first purpose-built computer centre in the world, hosting six Colossus computers by the end of World War II. The museum houses a rebuilt Mark 2 Colossus computer alongside an exhibition of the most complex code cracking activities performed at the Park, along with examples of machines continuing the history of the development of computing from the 1940s to the present day. The museum has a policy of having as many of the exhibits as possible in full working order. Although located on the Bletchley Park "campus", The National Museum of Computing is an entirely separate registered charity with its own fund-raising and separate entrance/ticketing. TNMOC receives no public funding and relies on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birkbeck College
Birkbeck, University of London (formally Birkbeck College, University of London), is a public university, public research university, located in Bloomsbury, London, England, and a constituent college, member institution of the federal University of London. Established in 1823 as the London Mechanics' Institute by its founder, Sir George Birkbeck, and its supporters, Jeremy Bentham, John Hobhouse, 1st Baron Broughton, J. C. Hobhouse and Henry Brougham, 1st Baron Brougham and Vaux, Henry Brougham, Birkbeck is one of the few universities to specialise in evening higher education in the United Kingdom. Birkbeck's main building is based in the area of Bloomsbury in London Borough of Camden in Central London. Birkbeck offers over 200 undergraduate and postgraduate programmes that can be studied either part-time or full-time, though nearly all lectures are given in the evening.

Birmingham Museum Collection Centre
The Museum Collection Centre (MCC) in Nechells, Birmingham, England, is a building that holds 80% of Birmingham Museums Trust's stored collections under one roof. It is one of the UK's largest museum stores. Among the thousands of objects stored there are steam engines (many of which are from the former Birmingham Museum of Science and Industry), sculptures, a collection of Austin, Rover and MG motor cars, a red phone box and a Sinclair C5. It opens to the public monthly, or by arrangement. There are also other open days, which tend to take place during the Spring and Summer Bank Holidays. The Museum Collection Centre is also home to The Museum in a Box service which enables schools and community groups to borrow original artefacts. In September 2014 then-trainee curator Lukas Large uncovered a taxidermied specimen of the long-extinct North American passenger pigeon The passenger pigeon or wild pigeon (''Ectopistes migratorius'') is an extinct species of pigeon that wa ...

Hollerith Electronic Computer1 Prototype
Herman Hollerith (February 29, 1860 – November 17, 1929) was a German-American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century. Hollerith founded a company that was amalgamated in 1911 with several other companies to form the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" ( IBM) and became one of the largest and most successful companies of the 20th century. Hollerith is regarded as one of the seminal figures in the development of data processing. Personal life Herman Hollerith was the son of German immigrant Georg Hollerith, a school teacher from Großfischling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powers-Samas
Powers-Samas was a British company which sold unit record equipment. In 1915 Powers Accounting Machine, Powers Tabulating Machine Company established European operations through the Accounting and Tabulating Machine Company of Great Britain Limited, in 1929 renamed Powers-Samas Accounting Machines Limited (Samas, full name Societe Anonyme des Machines a Statistiques, had been the Powers' sales agency in France, formed in 1922).

RAE Bedford
RAE Bedford was a research site of the Royal Aircraft Establishment between 1946 and 1994. It was located near the village of Thurleigh, north of the town of Bedford in England and was the site of aircraft experimental development work. In the book ''"A Short Illustrated History of the Royal Aircraft Establishment, Bedford"'', author Arthur Pearcy writes: ''"(RAE Bedford is) the finest research and development establishment outside the U.S.A."'' Starting in 1946, construction work began to turn the wartime RAF airfield into what became known as the Royal Aeronautical Establishment, Bedford. The runway was extended in the post-war period to accommodate the Bristol Brabazon aircraft, which required a very long runway but which never went into production. A lot of the development for what became the Harrier was done here, one early version became known as the 'Flying Bedstead'. Also Thurleigh had a catapult runway and it was here that the 'ski jump' later fitted to some aircraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Aircraft Establishment
The Royal Aircraft Establishment (RAE) was a British research establishment, known by several different names during its history, that eventually came under the aegis of the Ministry of Defence (United Kingdom), UK Ministry of Defence (MoD), before finally losing its identity in mergers with other institutions. The first site was at Farnborough Airfield ("RAE Farnborough") in Hampshire to which was added a second site RAE Bedford (Bedfordshire) in 1946. In 1988 it was renamed the Royal Aerospace Establishment (RAE) before merging with other research entities to become part of the new Defence Research Agency in 1991. History In 1904–1906 the Army Balloon Factory, which was part of the Army School of Ballooning, under the command of Colonel James Templer (balloon aviator), James Templer, relocated from Aldershot to the edge of Farnborough Common in order to have enough space to inflate the new "dirigible balloon" or airship which was then under construction.Walker, P; Early Avi ...
