---------------------------------------------------

If the upper set of pins are jumpered the AUI is enabled, if the lower
set is jumpered the thin net is enabled. And YES there IS a pin missing
from the top row on the left.

The default for the switches is:

DOWN, UP, DOWN, DOWN, UP, UP, UP, UP

Dont change them!
