Thanks. Unfortunately that does not seem to be it. Since the computer
currently behaves exactly the same no matter if there is a CPU in it or
not, I still assume that the CPU is the problem. By "flashing" characters
I meant the kind of things that you can get by typing FLASH from BASIC,
not characters that hop around randomly, so I doubt the RAM is really the
problem. I exchanged the lower bank with one of the others anyway, apart
from the fact that now closing square brackets occur more often among the
garbage nothing has changed. 

I have already run ads looking for broken VIC-20s and CBM 1541 drives in
our local free adspapers, those have socketed 6502s and also the 6522s I
need for the mockingboard, unfortunatly I had no success so far. Ordering
them via mail order seems to cost about $13 per chip which I think a bit
excessive.. oh well. 

Thanks anyway,
