Is there any merit in me bending out UE7/3 here to have something to compare to?
I don't think so Colin, but thanks anyway. Your measurements earlier made it quite clear that there is a fault on the UE7 / UF7 / UF9 node though, so that was a very valuable contribution.

We were just trying to think of how to replace the smallest possible number of devices necessary in BrackenFix's machine, but as he has already ordered replacements for all three I'm not sure if it wouldn't just be simpler to replace all three (one at a time, stopping at the point where the fault goes away) provided BF is completely happy that he can safely snip, remove and replace them.

I agree that looking at the keyboard is good use of the intervening time, so maybe we can all stand down until BF lets us know when the replacement chips have arrived.
