Fujitsu Siemens Computers GmbH was a Japanese and German vendor of information technology. The company was founded on October 1, 1999 as a 50/50 joint venture between Fujitsu of Japan and Siemens AG of Germany. On April 1, 2009, the company became Fujitsu Technology Solutions as a result of Fujitsu buying out Siemens' share of the company.2

The story

On the Fujitsu side, the origins of the company could be traced back to the mid-1980s merger of the PC divisions of Finnish Nokia and Swedish Ericsson, when Ericsson PCs were known for their ergonomics and bright colors. In 1991, Nokia Data was sold to the British International Computers Limited (ICL). Later ICL was absorbed by Fujitsu. Ironically, Fujitsu was originally the data division of Fuji Electric, whose name was derived from its founders; "Fu" from the Furukawa Electric zaibatsu, and "Ji" from jiimensu, the Japanese transliteration for Siemens.

The Nokia MikroMikko line of compact desktop computers continued to be produced at the Kilo and Lohja factories in Finland. Components, including motherboards and Ethernet network adapters were manufactured locally, until production was moved to Taiwan. Internationally the MikroMikko line was marketed by Fujitsu as the ErgoPro.

Also on the Fujitsu side, the company fully acquired Amdahl corporation in 1997 which was a manufacturer of IBM compatible mainframes. The mainframe market was an area where Siemens also had a strong presence, especially in Europe. The mainframe strategy of Siemens was different however as it produced its own line of mainframes that were not IBM compatible. Before the acquisition of Amdahl, Fujitsu also already had its own division that produced IBM compatible mainframes so the Amdahl acquisition was part of a market consolidation effort.

The German half of the company, Siemens Nixdorf Informationssysteme, was the result of the merger of Nixdorf Computer with Siemens' data and information technology branch.

In 2003, the company won the Wharton Infosys Business Transformation Award for their use of information technology in an industry-transforming way.

It was announced in November 2008 that Fujitsu would buy out Siemens' stake in the joint venture for approximately €450m with effect from April 1, 2009. Fujitsu Siemens was the last major Japanese/European computer manufacturer.

The Fujitsu takeover went ahead as planned on April 1, 2009—with the company renamed Fujitsu Technology Solutions. The FSC website was terminated.
