Mystic Marathon
---------------
Typed in by Mark Jenison
Corrections by tim@arcadecollecting.com.

Mystic Marathon is made up of two separate boards, connected together via
a pin connector (sort of like Atari System 1 boards are connected).  I'm 
going
to refer to the boards as the RAM board (the board which contains the 3x8 
bank
of 4116 Rams), and the ROM board (the board that contains the most ROMs).

RAM board - pins labeled such that LOWEST number is nearest the RAMs, 
starting
with the connector closest to the RAMs.
