It may be an EF 9365 or EF 9366. That's a graphics display processor with vector capability. It was used for the NDR computer by Rolf Dieter Klein. See here http://de.wikipedia.org/wiki/NDR-Klein-Computer (German) and here http://upload.wikimedia.org/wikipedia/commons/e/ef/NDR_Klein_Computer_GDP64_Karte.JPG for a picture of the card. Maybe someone has event put this card into the machine with some interface logic?
