I was wondering if anybody knows if it is possible to just piggyback a keyboard controller chip, for the sake of diagnostics.
I have a board that doesn't receive any input from the keyboard port, but visual inspection doesn't show any damaged traces or anything indicating damage to the board.
This leads me to think that it is probably a faulty keyboard controller chip. I have a replacement chip, so I was wondering if anyone knows if it's possible/safe to just piggyback the new controller chip to see if that fixes the problem?
I'd rather not have to do the whole soldering job to replace the chip if that isn't going to fix the problem, which is why I'd like to be able to test it before desoldering the old chip.
