TDC1007 / 1007 / TRW / Rare TRW Processor ?

Something like that was built at the University of Illinois PLATO project, but much lower cost -- 16 small boards (one per channel) and some spare cycles on the 8080 in the terminal to control it. That one was actually mostly analog, each channel having its own D/A and analog volume control. We actually looked at the TRW multiplier approach for a third generation with 128 channels but decided it was too expensive other than as a lab curiosity, which wasn't the goal. This was the "Gooch Cybernetic Synthesizer" by Sherwin Gooch, around 1976. paul
