Hmm. OK, the 6502 from the SK is dead (tried it in the working 8032, nada).
However, that's not the only problem, as when I substituted the working
6502 + other missing chips from the 8032 to the SK, it still didn't fire
up. I think the easiest way to fix this might be to find a working normal
8032 board & subby the whole lot. Fortunately, I have a US 8032 en route to
me even as I write (about 3-5 weeks away from me ATM), so I could use that,
then try to fix the proper board over time.
Cheers!
Ade.
