And the original clock circuit with discrete elements? There was AFAIR also a kind of PLL involved. Do those exhibit the same problem? the original C64 clock generator circuit (is) a regular PLL (so, not "a kind"), the reference divider circuit is inside the VIC-II IC which is part of the PLL. The MOS8701 is a divider/digital delay synthesizer and doesn't use the VIC-II divider (but the divider it's still needed to generate the 6510's clock). Just for the record.
