1771 floppy controller questions

HP made a series of device testers that live on a test clip that you plug on
in-situ, and if it's designed for one set of supplies, and you hook up another,
you may not be pleased with the results. I've got a few of those out-of-circuit
testers, but the one I thing he (Tothwolf) is using is one of the type I'm
referring to. It would be a shame to damage one, as it can test a soldered-in
part without first unsoldering it.
