Btw, as far as I know (or am I wrong?) some timing is based on the frequency
of the AC 9V. So in the USA it's 60Hz, where here it's 50. Just converting
the voltage would work I guess, but the frequency difference can cause
different timing. I can't remember now where it's used though, if it is at
all. Maybe does CIA use it? My assumption that NTSC C64s generated NTSC
video signal and except 60Hz, and PAL ones except 50Hz, so not only the
video signal and the PSU input AC voltage is the difference.
