Yup, most definitely a 6502A (I also verified this worked by putting it
into my good Asteroids board).

Ewwwww - nasty! I have a horrible feeling that I may have quite a few more
fried components given the amount of faults I've found so far, so this one
could be a pig to fix especially given my relative lack of knowledge.
I have a logic probe on order, so that should at least help a bit.
I don't suppose anyone has an Atari CAT Box they can loan me ....... ? ;)
