"He knew every transistor and every wire in his computers." -- Danny Hillis I recall hearing a story years ago about one of his machines, perhaps a 7600. It seems a technician had been called to service the machine, and in the process, noticed a wire that was quite a bit longer than the distance between the two points it connected. The technician replaced the wire with one cut to length... and the machine stopped working. Cray was using the speed-of-light delay to time some signal.
