Darn thing has enough muscle that it motors on even with 3 or 4 cards plugged in! So many of the newer S-100 cards have little, or no, requirement for anything but +8 that any number of cards will not drain off the +/- 16v supply. I only discovered what was going on when I stuck the "bus breakout" card in there. Might need bleeder resistors, or something. I was just trying to warn whoever bought the box (if it was somebody here) that it *could* be a problem. But .... it is a *nice* box.
