Switch Settings

There are no DIP switches on the Equity Ile. However,
there is a CPU SPEED switch on the front of the unit in
the lower left hand comer.
The CPU SPEED switch selects between 8MHz and
12MHz. When the computer is running at 8MHz, the
power light is orange, and at 12MHz, the light is green.
