I read an interesting article (no doubt written by someone at IBM)
that shipments of IBM 370 architecture machines has never slowed down
(now called S/390). I remember writing PL/1, COBOL and BAL for those
giant fossils. I also remember seeing an emulation running on a
486 laptop that ran faster than the original machine.
Somehow I'm not buying this. I know there's a "y2k" play here
somewhere but I don't quite see it yet.
