Well, a true hardware hacker can find out by getting the datasheet of the MC12439 clock generator chip. The dipswitch SW1 controls the multiplier that the MC chip uses to multiply the 16.6666Mhz crystal frequency. My own experiments made me decide not to include non-standard multiplier tweaks in the docs. One can e.g. get a 533MHz clock freq on the CPU. That worked on my 500MHz CPU. But the speed delta is not interesting IMO.
