Thanks to the input of a reader I updated the East German CPU page to be much more accurate as to the various institutions that existed, and their respective logos. There were institutions in three different cities (Erfurt, Frankfurt, and Dresden), and they had amongst them 7 different names and a variety of logos.
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.
The updated page should help ID’ing them a bit easier.
