Re: Non-working Commodore PET 3016
OK - I've narrowed down the keys with problems to one trace. None of the keys attached to this trace work.
As far as I can see, the issue is in the (I'm sure these are the wrong words) jump trace on Pin I of the attached picture - the one that starts just below where the cable actually is and rejoins between \ and (.
I have continuity from one end of Wire I to the other. I have continuity from the solder point of wire I to just before the 'jump'. I have continuity from after the 'jump' to all of the affected keys.
I've attempted to circle it here. I believe that I should have continuity between the two ends of the jump - is that right?
Colin.
