I have a converted C116 that I brought to a TPUG meeting. For the 264/TED
series of machines it's fairly easy as the TED chip is both PAL and NTSC
compatible and is set by a single bit in a register. This is set by the Kernal
chip on bootup. There is a PAL and NTSC kernal. You also need to feed the
proper frequency so you have to change the XTAL too.
For the C64 there is a PAL VIC-II chip and an NTSC VIC-II chip, so you need to
change the chip, the XTAL and some jumpers. AFAIK you don't need to change the
Kernal on the C64. I also just learned from that document that you need a new
capacitor...
Anyone have a spare PAL VIC-II chip? I just picked up an LCD TV that can handle
PAL!
