In the summer of 1971, I had a job at the junior college where I attended working in the electronics technology lab inventorying and organizing. Some company donated an old computer to the college for a tax right off I am sure. It was ancient. Massive 19inch racks with motherboards into which smaller PC boards plugged into. Big honking power supplies and lot of fans. All vacuum tubes. The college did not even offer courses in vacuum tubes any more. I doubt if we could have got the dinosaur working again. The chairman of the department tasked me and a few other students to salvage what might be useful and haul the rest to an outfit that recycled the rest. I wish I would have kept a few things. "Now this 6X6inch PC board with a bunch of tubes and other components must be a NAND gate?"
