Editing Datasaab

'''Datasaab''' was the computer division of, and later a separate company spun off from, aircraft manufacturer [[Saab Group|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 tube]]s, from [[Matematikmaskinnämnden]] (the Swedish governmental board for mathematical machinery). This clone was completed in {{start date and age|1957|p=y}} and was named [[SARA (computer)|SARA]]. Its computing power was needed for design calculations for the next generation jet fighter [[Saab Viggen|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 [[transistor]]ized prototype computer named [[Datasaab D2|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 the commercial market.

The military navigational computer CK37 was completed in 1971 and used in Viggen.

The first civilian model D21 (1962) was sold to several countries and some 30 units were built.  After that, several versions with names like D22 (1966), D220, D23, D5, D15, and D16 were developed. When the Swedish government needed 20 computers in the 1960s to calculate taxes, an evaluation between Saab's and [[IBM]]'s machines proved Saab's better. Later the D5s were used to set up the first and largest bank terminal system for the [[Nordic countries|Nordic]] banks, a system which was partly in use until the late 1980s. In 1975, the D23 system was seriously delayed and the solution was to spin off the large and medium systems to a joint marketing/services company with [[UNIVAC|Sperry UNIVAC]] called Saab-Univac.<ref>{{cite news |title=THE TALE OF WOE THAT LED UP TO THE SALE OF ERICSSON's COMPUTER ARM - Tech Monitor |url=https://techmonitor.ai/technology/the_tale_of_woe_that_led_up_to_the_sale_of_ericssons_computer_arm |date=1 February 1988}}</ref><ref>{{cite book |last1=Bubenko |first1=Janis |last2=Impagliazzo |first2=John |last3=Soelvberg |first3=Arne |title=History of Nordic Computing: IFIP WG9.7 First Working Conference on the History of Nordic Computing (HiNC1), June 16-18, 2003, Trondheim, Norway |date=14 January 2005 |publisher=Springer Science & Business Media |isbn=978-0-387-24167-8 |page=259 |url=https://books.google.com/books?id=qZIgLbka3ogC&pg=PA259 |language=en}}</ref> Eventually Sperry would take full ownership of Saab-UNIVAC once it had completed the conversion of the Saab Mainframe customerbase to the [[UNIVAC 1100/2200 series|1100 series]].<ref>{{cite book |last1=Hills |first1=Jill |title=Information Technology and Industrial Policy |date=26 March 2018 |publisher=Routledge |isbn=978-1-351-24043-7 |page=223 |url=https://books.google.com/books?id=riZTDwAAQBAJ&pg=PT223 |language=en}}</ref>

In 1971, technologies from [[Standard Radio & Telefon AB]] (SRT) and Saab were combined to form [[Stansaab]] AS, a joint venture that also included the state-owned Swedish Development Company.  The company's primary focus was systems for real-time data applied to commercial and aviation applications.<ref>{{cite web |url= http://www.flightglobal.com/pdfarchive/view/1972/1972%20-%203354.html | work = Flightglobal | title = Archive | year = 1972 | access-date = 2008-10-29}}</ref>

In 1978, Stansaab merged with the Datasaab division of [[Saab-Scania]] to become Datasaab AB.<ref name = veterans>{{cite web | url= http://www.veteranklubbenalfa.se/veteran/foretag.htm |trans-title=Short history of SRT, Stansaab and Datasaab | title = Företag | language = sv | publisher = Veteran klubben Alfa | access-date= 2008-10-29}}</ref>  It was later owned by [[Ericsson]], [[Nokia]] and [[International Computers Limited|ICL]].

When [[Intel]] sued the competitor [[United Microelectronics Corporation|UMC]] for [[patent]] infringement over technologies including [[microcode]] updates of [[central processing unit|processor]]s and different parts of the processor working asynchronously, UMC could point to an awarded paper describing how these technologies had been used in the D23 already in 1972. Since Intel's patents were from 1978, that paper would prove prior art and imply that the patents never should have been granted at all. The case was later dropped.

The academic computer society [[Lysator]] at [[Linköping University]] was founded in 1973 when a donation of an old used D21 was arranged. The company's history has been documented by members of its veteran society, ''Datasaabs Vänner'' ("Friends of Datasaab"), founded in 1993 to document and spread information about the computer history of Sweden, with focus on the region of Linköping and Datasaab. The society has documented the Datasaab history in five books, and documents and pictures of computer systems and products developed and produced by Datasaab are presented at the society homepage. Since 2004 many Datasaab computers are exhibited at the [[IT-ceum]] computer museum in Linköping.

After a series of mergers, the name Datasaab became connected with an incident of illegal [[technology transfer]] to the [[Soviet Union]] in the late 1970s.<ref>[[Linda Melvern]], Nick Anning, David Hebditch, ''Techno-Bandits : how the Soviets are stealing America's high-tech future'' (1984) Boston : Houghton Mifflin, {{ISBN|0-395-36066-8}}, Swedish translation by Bo Kage Carlson the same year, ''Teknobanditerna : om smuggling av högteknologi från väst till öst'', Stockholm : Svenska Dagbladet, {{ISBN|91-7738-064-9}}</ref> A 1973 bid for tender for a civilian [[air traffic control]] system at the airports in [[Moscow]], [[Kyiv]], and [[Mineralnye Vody]] was won by Swedish supplier [[Stansaab]]. A contract between Stansaab and [[Aeroflot]] was signed in September 1975. However, parts of the delivered system relied on components from the US, for which the Swedes couldn't get the necessary export licenses. So they bought U.S. components, relabeled them and smuggled them to Moscow using Soviet diplomats. Datasaab separated from Saab in 1978 and joined Stansaab in a new company, Datasaab AB.<ref>{{cite web

Allegedly the air traffic control system did support the Soviet invasion of [[Afghanistan]] in December 1979. The smuggling operation was uncovered in October 1980, known as "the Datasaab affair" (''Datasaabaffären''). In early 1981, Datasaab was acquired by [[Ericsson]] and became its computing division Ericsson Information Systems. In April 1984 Ericsson was fined US$3.12 million for breach of U.S. export controls, and agreed to pay.
