East German CPU’s
Thanks to Mr Rüdiger for his help
East Germany was a powerhouse of CPU development for the Soviet States.
There were 3 institutions manufacturing IC’s in East Germany (their names changed a few times making it appear there were more). One each in Frankfurt (Oder), Erfurt, and Dresden.
The plant in Erfurt was initially called VEB Funkwerk Erfurt, short FWE. In 1983 the plant was renamed VEB Mikroelektronik “Karl Marx“ Erfurt, short MME. Its products were marked with the stylized ‘fwe’, the letters ‘FWE’, or the letters ‘MME’. From 1992 until 1999 the plant continued under the name Thesys Gesellschaft für Mikroelektronik mbH and the ICs were marked THESYS.
The plant in Dresden was initially Institut für Mikroelektronik Dresden (IMD) and used the logic gate logo. In around 1980 IMB became VEB Zentrum für Forschung und Technologie Mikroelektronik (ZFTM).In 1986 ZFTM became part of the Carl Zeiss Jena organization (the other two plants remained part of an organization called Kombinat Mikroelektronik). The Carl Zeiss logo was apparently only used for the 1Mbit DRAM chips from Dresden (U61000). In 1987 the plant was again renamed, this time to VEB Forschungszentrum Mikroelektronik Dresden (ZMD).
It helps to remember that IC’s were made different in East Germany. There was not so much corporations as we think of them in the West such as Intel or AMD that made this or that. In East Germany (and the USSR) IC’s (and most everything else) were made by institutions, that were typically a government organization, or sanctioned by the government to do/make certain things. These could be changed, consolidated, opened/closed at the whim of the government resulting in a lot of confusion in identity. Add to that the changes brought with the fall of communism, and these institutions transition to modern corporation and you get some very interesting collecting opportunities.
Often East German CPUs will be referred to as DDR (Deutsche Demokratische Republik),
the initials of the East German state.
East German CPUs are dated in the following manner:
This UB880D was made in December 1988
This list is not complete but is meant to give you an idea of what is was going on outside the US.

I would like to thank Genna of CPU-World and Frassal (from Germany) as for their pictures that made this possible.
