Re: Non-working Commodore PET 3016
I did idly wonder if the other gate in UB2 is used for anything because if not we could perhaps have tried to patch the unused-hopefully-OK gate in, Tim style, to see if that made a difference.
Unfortunately the other gate is used, as part of the address decoder on sheet 1. If we conclude that we have to replace UB2, doing so might even fix a few other problems which we don't even know we have yet.
