Hi Gene,

I bet you had fun finding and resolving this puzzle. I find that no matter how well I think I have made something there are always side effects that pop up to challenge me. Great job fixing the damaged boards. Hopefully you will have no further problems with them.

Great piece of fault finding, you certainly have a lot more capability and patience than I do to work on this kind of equipment. I think that would of ended up on the rifle range if it was mine.

Kind regards.

Good post, it is always fun to hear about what happens to circuits in the real world as they get used and abused.

That is nice repair work Gene. Once or twice I have managed to wipe out pins through clumsy behavior on my part late at night when interfacing between 5V parts and 3V3 microcontrollers. It can be all too easy to do. I am also quite adept at stripping pads :-)
