For those curious about the equipment that sold last week, I put together an album from my brief stop on Saturday. Let me know if you have trouble viewing it. https://goo.gl/photos/yb83SJSj67gS96n39
On closer inspection it appears the documentation for that GP-4, as well as some of the other computers, sold to different parties (the value being in the shelving and cabinets). I'm still losing sleep over that GP-4. From all appearances it was a turn-key setup (in theory). Unfortunately, the auction site immediately removes closed lots from their webpage so no idea what it sold for, or if it went to a scrapper. I suspect it was billed as 'cabinets of aviation equipment'. Being 3 hours away I can't exactly run over there and pin a note on it. Some further digging on the net revealed a photo in the Motorola Annual Report 1965 featuring the machine touting Moto's new ECL logic. Apparently it was designed for aviation simulation but included facilities for being a general purpose machine. -C
