Maybe I was unclear on what I meant by "jumpering across": you put a
wire between pin 1 and pin 3 of the regulator. With such a jumper,
it's impossible for the input to drop below output at the regulator.

Of course, you've got to remember to remove the jumper before putting
the resulting card back into a system with unregulated power busses!

Like I said, regulated S-100 power busses were done by several manufacturers
in the early and mid-80's with great success. It's a non-issue.
