A while back, i talked about the PAL-N VIC-II present on the Argentinean license 'built' C-64s.

But, thanks to Juan Carlos Fekete and electroeject, members of Retrocomputacion.com forum, I realized that my calculations were wrong.

I assumed that the clock circuitry is working in PAL mode, which means that the crystal frecuency gets divided by 18 to get the processor clock frequency. In fact, the clock circuitry is working in NTSC mode: The crystal frequency gets divided by 14 to get the processor clock frequency.

Thus, according to the previous calculations the crystal frequency must be:


WRONG!

Second mistake, I didn't noticed that the colorburst carrier frequency is the crystal frequency divided by 4.

The colorburst carrier frequency for PAL-N is 3.582056MHz

This is confirmed by this picture by Juan Carlos Fekete of a rev.A motherboard (note the 6572R1):
