In the 60's and 70's, there was an outfit called "American Used Computer" in Mass. Based on what I've seen, they took reject PDP-8's, -9's, -10's, -11's, Novas, etc., from dumpsters and tried to reconfigure them into saleable (maybe not workable!) systems. (Sort of the same way Poly Paks took cast-offs parts from the same companies and sold them.) Anyway, a truly classic picture of dozens of H960 racks filled with stuff and the proprietor is online if you go to http://www.nixiebunny.com/ and click on the picture at the "American Used Computer" link. By the time I was into this stuff, the outfit was long out of business, but my colleagues told legends about the mismatched boards they put together and tried to sell as complete working systems :-).
