My wife worked there when we first met. She told me she knew where there was a Cray-1 sitting at the bottom of a stair well. Obviously this raised my level of interest. We went up there on the weekend and took each other's photo sitting on it. From memory it was a very low serial number having been shipped to <some-TLA> first then subsequently moved to NCAR. I also peered through the glass at various exotica in the machine room: YMP, KSR, TM that sort of thing. Great first date.
