The Sage early warning computer had a drum storage unit that was about five by eight feet by six feet high. It stored around 128 Kbytes. It was retired in the early 1980s (!). They have one (drum unit, front panel, etc.; not everything) at the Boston Compter Museum. You wanna tell us how good computing was in the fifties, go hop on a period machine, say a Bendix G15 (I think I know where you can find one), and try to use it to do *anything*. -- -- uunet!ficc!karl "Have you debugged your wolf today?"
