FACIT EDB
FACIT EDB was a vacuum tube based computer that was manufactured by Åtvidabergs Industrier AB after the designs for BESK, that had been developed by the Swedish Board for Computing Machinery (Matematikmaskinnämnden). FACIT EDB was the first fully Swedish series production computer. EDB stod for "Electronic Computer Processing". The manufacturing was done by Åtvidabergs Industrier department of electronics in Stockholm and came to fruition by recruiting 18 key persons from the Swedish Board for Computing Machinery (Matematikmaskinnämndens). Internally nicknamed "the Besk boys". In 1960 the department became Facit Electronics with a new factory in Solna. The recruitment of people from Swedish Board for Computing Machinery were approved by the Finance minister Gunnar Sträng. That thought that production of computers was not something the government should be involved in.

Facit 1285 - Museum Of Technology In Warsaw - Poland
Facit (''Facit AB'') was an industrial corporation and manufacturer of office products including furniture. It was based in Åtvidaberg, Sweden, and founded in 1922 as ''AB Åtvidabergs Industrier''. Facit AB, a manufacturer of mechanical calculators, was incorporated into the corporation the same year. In 1932, the first ten-digit calculator was manufactured by Åtvidaberg Industries, it was named FACIT and became a great success. In the 1950s, Facit introduced a mascot character, a short, smiling man with a wizard's cap called "Facit Man". The character first appeared in the instruction manuals for Facit's calculators. The character lasted into the 1970s. By the early 1960s the corporation had a total of 8,000 employees with subsidiaries in over 100 countries, and the subsidiary Facit had come to dominate the business of the corporation. In 1965 the entire corporation changed its name to ''Facit AB''. The following year, it acquired its competitor '' Addo'', which was maintai ...

Diode
A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices. The discovery of asymmetric electrical conduction across the contact between a crystalline mineral and a metal was made by German physicist Ferdinand Braun in 1874. Today, most diodes are made of silicon, but other semiconducting materials such as gallium arsenide and germanium are also used. Among many uses, diodes are found in ...

Crystallography
Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (''krystallos'') "clear ice, rock-crystal", with its meaning extending to all solids with some degree of transparency, and γράφειν (''graphein'') "to write". In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography. denote a direction vector (in real space). * Coordinates in ''angle brackets'' or ''chevrons'' such as <100> denote a ''family'' of directions which are related by symmetry operations.

Datasaab D2
200px, Datasaab D2 computer at IT-ceum 200px, Front panel D2 was a concept and prototype computer designed by Datasaab in Linköping, Sweden. It was built with discrete transistors and completed in 1960. Its purpose was to investigate the feasibility of building a computer for use in an aircraft to assist with navigation, ultimately leading to the design of the CK37 computer used in Saab 37 Viggen. This military side of the project was known as SANK, or ''Saabs Automatiska Navigations-Kalkylator'' (''Saab's Automatic Navigational-Calculator''), and D2 was the name for its civilian application. The D2 weighed approximately 200 kg, and could be placed on a desktop. It used words of 20 bits corresponding to 6 decimal digits. The memory capacity was 6K words, corresponding to 15 kilobytes. Programs and data were stored in separate memories. It could perform 100,000 integer additions per second. Paper tape was used for input. Experience from the D2 prototype was the foundatio ...

ALGOL
ALGOL (; short for "Algorithmic Language") is a family of imperative computer programming languages originally developed in 1958. ALGOL heavily influenced many other languages and was the standard method for algorithm description used by the Association for Computing Machinery (ACM) in textbooks and academic sources for more than thirty years. In the sense that the syntax of most modern languages is "Algol-like", it was arguably more influential than three other high-level programming languages among which it was roughly contemporary: FORTRAN, Lisp, and COBOL. It was designed to avoid some of the perceived problems with FORTRAN and eventually gave rise to many other programming languages, including PL/I, Simula, BCPL, B, Pascal, and C. ALGOL introduced code blocks and the begin...end pairs for delimiting them. It was also the first language implementing nested function definitions with lexical scope. Moreover, it was the first programming language which gave detail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
