The probability of sampling it in the active state woud be very low for sampling rates of a few Hz.

and there is the problem,
it's going to be checking clock,address,data and chip-select lines on old computers.

So you want min/max peak detector connected to LM3914 LED bar graph..

This is what I keep thinking but does he really want to see the under and overshoot? I think I just need to wait and see what he comes up with and how it is used.

I agree.. I kinda understand what he wants to measure. It's just I simply use scope for that..
