In 1993 Siemens acquired ELWRO, Polish computer manufacturer (RIAD - IBM 360/370 mainframe clones for Russian/Indian market) and ZWUT, Polish telecommunication equipment manufacturer. They paid $38mln. First thing they did was to fire everyone from ELWRO. They also send manufacturing lines and unused parts stock back to Germany, and on top of it demolished manufacturing plants and sold off bare land. Good old German efficiency, scorched earth policy. 7 years later Siemens finished this "investment" by selling remaining telecomm part of the company to US investor Telect who planned to manufacture fiberoptic switches in Poland. Rumor has it Telect came to some sort of a deal with Nortel and closed manufacturing in Eastern Europe as a result.

And that was that, from Mainframe manufacturer to nothing in 7 years from Siemens acquisition.
