DDM PDP11 Electronics Rack

Control card dated 1974. Believed to be from the Stadttheater Baden-Baden. 240 control channels. Ampex modules are ferrite core blocks used for the show memory (similar to those used in MMS). Ferrite core blocks were used because they were non-volatile and retained their contents when the power was off.
