* At the bottom center of the Sound II board, there is a section labeled
"Color Conv."  At the far left you will see switch #4 (SW4).  If this switch
is off ("0"), you will get JAMMA compatible negative composite sync.  If it
is on ("1"), you will get positive composite sync.

Items in parantheses "()" are only needed for the cocktail setup, or perhaps
as extra pinouts.

There is an additional 10pin connector between P1 on both boards.  Pin 1
on the sound board maps to pin 1 on the video board, pin 2 on the sound
board maps to pin 2 on the video board, etc.  A Zaxxon boardset should come
with the connector between these two sets of pins.

There is an additional 6pin MTA connector at P4.  I believe it is needed 
to get sound.
