That's because the 64 with NTSC VIC-II but PAL crystal was producing a hybrid video standard known as NTSC 4.43. Some PAL video recorders use it when displaying NTSC tapes. The trouble with that setup is that the horizontal line frequency is a bit out, which my old TV didn't like at all. > Converting VIC20 from PAL to NTSC though..
