Hallo Philip,
 

> One last question: did my voltages off the CPU look ok?

Yes. A rather busy SYNCbut I know the 6502 halts when it reads $FF and
that could affect SYNC.

Another idea: I once had te repair a 3016 I replaced the top ROM with
one of my own that just placed some text on the screen. That assured me
the CPU part + top ROM was OK and that I first had to concentrate on the
video part and then, if still needed, on the rest.
