I do software development on my PC AT, which means that it hangs a lot.
Turning it off and on is a pain, and isn't very good for the disks and
the screen either. It is my impression that it should be fairly easy to
build a little circuit that when I push a button zaps the reset line inside
the PC and restarts it as though the power had just been restored. Please
mail me responses; I'll summarize if there's interest.
I realize that there are various software ways to try to catch keystrokes
and reset, but my programs are sufficiently vicious that only a hardware
reset will do.
TIA,

I have a spring loaded push button connected to an on board jumper by twisted pair wires that I can hit on the back of my AT clone. The jumper is documented in the motherboard technical sheets. Presumably a similar jumper exists on yours. Ask your local hardware technicians, maybe. Ross W.

(in 1/2 hour) There is a 8284 clock chip close to the 8088 CPU, this chip controls the cold boot reset ie. when you power up, this chip sends a reset pulse to everything. You can force this chip to send a reset pulse to everything by pulling its pin #11 low. This won't harm your system at all since you are doing the same thing when you turn your sytem on/off.
