3. CPU External (BUS) Frequency Selection (JP2, JP3)
These jumpers tells the clock generator what frequency to send to the CPU.
These allow the selection of the CPU's External frequency (or BUS Clock). The
BUS Clock times the BUS Ratio equals the CPU's Internal frequency (the ad-
vertised CPU speed).
