Most of my machines sport a parallel port; all of them are of the variety where you connect a dual-row IDC connector and some ribbon cable with a DB25 on the end up to it (as opposed to being directly soldered to the back of the board). This means I _could_ design a daughtercard inside the machine that connected to the parallel port, the reset switch, and maybe fd power. It would be adequate. I'm just trolling to see if somebody has a solution I don't have to work so hard at :-) ...
