I have a breadbox C64 and one of the earlier C64c with the old PCB, so
no luck there.

Martijn> you'll most definately need 9V AC,

OK. I guess I'll have to get creative. I could always mount the C64
power supply inside the case and connect it's ground to the PC PSU.
  Does the 128 use 9V AC?

Does anyone use the TOD?
