Woops. My fuzzy memory seems to recall the IBM PC 5150 I bought 2nd hand did
have a small red reset button on the back of the PC. I'd guess the hacker I
purchased it from added some wires to pins 20 and 21 of the 8088 (By Bridging
Pins 20 and 21 of the 8088 CPU, you can hard reset the system).

But you are correct, I believe only clones had reset buttons (very handy, too).
Thanks for clearing my misconception. TomD
