SARA (computer)
SARA (SAABs räkneautomat, SAAB's calculating machine) was developed by SAAB when the capacity of BESK was insufficient for their needs. The project was started the fall of 1955 and became operational in 1956. SARA was built using the drawings of BESK that SAAB had bought for a symbolic sum and with the help of people who had worked with BESK, but didn't stay when Matematikmaskinnämnden decided that there would be no second generation. SARA wasn't used much, but it became the start of DataSAAB Datasaab was the computer division of, and later a separate company spun off from, aircraft manufacturer Saab in Linköping, Sweden. History Its history dates back to December 1954, when Saab got a license to build its own copy of BESK, an early ... and the development of CK37 and D2.

Saab Group
Saab AB (originally , , acronym SAAB), with subsidiaries collectively known as the Saab Group (), is a Swedish aerospace and defence company primarily operating from Sweden. The company is headquartered in Stockholm, but its development and manufacturing operations are undertaken in Linköping. The company was formally founded by AB Bofors in 1937, by reforming the aero engine division of company NOHAB (founded in 1930), located in Trollhättan, into a proper aircraft manufacturer. It would soon merge with aircraft manufacturer ASJA (founded in 1931), located in Linköping, in 1940, which had it own design bureau and is considered the spiritual predecessor to today's Saab AB. This formed the SAAB- concern, with the factory in Trollhättan becoming ''SAAB/T'' and the factory in Linköping (previously ASJA) becoming ''SAAB/L'' and design headquarters. From 1947, Saab started producing automobiles, the automobile division being spun off as Saab Automobile in 1990, a joint vent ...

BESK
BESK (''Binär Elektronisk SekvensKalkylator'', Swedish language, Swedish for "Binary Electronic Sequence Calculator") was Sweden's first electronic computer, using vacuum tubes instead of relays. It was developed by ''Matematikmaskinnämnden'' (Swedish Board for Computing Machinery) and for a short time it was the fastest computer in the world. The computer was completed in 1953 and in use until 1966. The technology behind BESK was later continued with the transistorized FACIT EDB and FACIT EDB-3 machines, both software compatible with BESK. Non-compatible machines highly inspired by BESK were SMIL (computer), SMIL made for the University of Lund, ''SAABs räkneautomat'' SARA (computer), SARA, "SAAB's calculating machine", and DASK made in Denmark. BESK was developed by the Swedish Board for Computing Machinery (Matematikmaskinnämnden) a few years after the mechanical relay computer BARK (computer), BARK (Binär Aritmetisk Relä-Kalkylator, Swedish for "Binary Arithmetic Re ...

Matematikmaskinnämnden
The Swedish Board for Computing Machinery (, MMN) was a Swedish government agency which built Sweden's first computers: BARK and BESK. A governmental study into the need for computing machinery in Sweden had been conducted in 1947 by initiative of the Royal Swedish Academy of Engineering Sciences and the Naval Procurement Agency. The study recommended the immediate purchase of computing machinery from the United States and a budget of 2 million SEK was allocated for the purpose. The Swedish Board for Computing Machinery was established on November 26, 1948, to handle the purchase. , accessed on August 30, 2009 The Academy of Engineering Sciences had initiated some activities already in 1947 by sending five young engineers and scientists to research groups in the United St ...

DataSAAB
Datasaab was the computer division of, and later a separate company spun off from, aircraft manufacturer Saab in Linköping, Sweden. History Its history dates back to December 1954, when Saab got a license to build its own copy of BESK, an early Swedish computer design using vacuum tubes, from Matematikmaskinnämnden (the Swedish governmental board for mathematical machinery). This clone was completed in and was named SARA. Its computing power was needed for design calculations for the next generation jet fighter Saab 37 Viggen. Intending to develop a navigational computer to place in an airplane, a team led by Viggo Wentzel came up with an all transistorized prototype computer named D2, completed in 1960, which came to define the company's activities in the following two decades. This development followed two lines. The main purpose was the development of a navigational computer for Viggen. A spinoff was the production of a line of civilian mini and mainframe computers for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 foundation ...
