I have another A1200 motherboard that is PAL and has the right clock port pins, but my question is, how can I make the PAL motherboard a NTSC one? Are there chips I can swap out? Traces I can cut or build?
Alice pin 41 controls whether it's ntsc/pal. A google search for "amiga alice pin 41" should give you an idea.
Obviously this just affects the refresh rate, the composite video output will be PAL60. So everything will look black and white in NTSC land.
The RGB video will be fine though.
