[] Thanks to those who described how to build such a switch for 8088-based machines on behalf of those who use them. How about one for '286 machines? Is the technique the same? -- Tom Reingold tr@bellcore.com

How about one >for '286 machines? Is the technique the same? I built one for about five bucks. The AT has a "power good" signal coming out of the power supply; if you pull that signal down to ground for a moment the AT will think that it's just been turned on and reboot. I put a momentary contact switch in series with a 220 ohm resistor (I picked 220 just because I had one lying around and didn't want to short the +5 directly to ground.) Power good is pin 1 on the PS8 power connector and a convenient ground is pin 6 on the same connector. I just folded over the leads from my switch and stuffed them into the back of PS8 to avoid any cutting or soldering. Works great. -- John R.
