East German CPUs

East Germany was a powerhouse of CPU development for the Soviet States.
There were 5 companies making electronics there.
Often East German CPUs will be reffered to as DDR (Deutsche Demokratische Republik),
the initials of the East German state.

Initials	Name	Logo	Notes:
FWE	Funkwerk Erfurt		The predecessor of MME
ZMD	Zentrum für Mikroelektronik Dresden
HFO	Halbleiterwerk Frankfurt/Oder
CZJ?	Carl Zeiss Jena		World famous for their optics, also make fab equipment now
MME			Developed from FWE

East German CPUs are dated in the following manner:
