Compiling one in *two seconds* of wall-clock time, however, is perfectly possible, and it would have been impressive on a computer made from discrete transistors. So I think the problem is that he meant a completely different kind of "clock tick" from the kind you were thinking of that the GE 635 didn't have. John Savard
