"A kind" was in the meaning of "one of possible kinds", not in the meaning of "exotic" or so.

Right, what I am interested in is whether the C64s with the original clock generator circuit (the regular PLL/VCO) exhibit the same problem with said peripherals as the "Reloaded" (and - as gpz says - the newer boards equipped with the 8701 replacement). If that's the case, then it is hard to argue that it is a compatibility issue on the "Reloaded" side. One could even say that "Reloaded" is more compatible with the original design... ;-)
