Quoted from KenLayton:A friend was lucky to get one of Ed's Quickscan 80 testers. It sure makes it alot faster and easier to repair System 80 boards. I wish Ed could develop a newer, better one with an LCD display instead of a single digit LED. Or maybe come up with with some sort of tester/adapter that could plug the System 80 board into a laptop with a software program which would have extensive diagnostics.
I don't even have a system 80 pin at the moment, but I sure would be on board for something like this!
