4. CPU External (BUS) Frequency Selection (DIP1, 2, 3)
These function 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
advertised CPU speed).

5. CPU to BUS Frequency Multiple (DIP7, 8, 9, 10)
These function switches set the frequency multiple between the Internal fre-
quency of the CPU and the External frequency (called the BUS Clock) within
the CPU.
