Hmm, years ago when ACS was open in Sacramento, I had a PAL A1200 converted to NTSC by owner/tech Jim Sutherland. He told me that he changed one resistor and cut 4 traces. It worked!
However, a few months ago TOGA tech Duncan M. told me that was not right. Maybe what he meant to say was that it was not a complete conversion. Perhaps you're list of changes above is more complete.
