III. HARDWARE SETUP
4. CPU External (BUS) Frequency Selection (DIP1, 2, 3)
These DIP switches tell 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).

5. CPU to BUS Frequency Multiple (DIP7, 8, 9, 10)
These DIP switches set the frequency multiple between the Internal frequency
of the CPU and the External frequency (called the BUS Clock) within the CPU.
3.0x(3/1) 3.5x(7/2) 4.0x(4/1)
MEL-C CPU : BUS Frequency Multiple
Set the DIP switches by the Internal speed of your processor as follows:
