Pinouts for Sega/Gremlin Space Odyssey (1981):
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This info was obtained from an original Space Odyssey
'Preliminary Manual' (operators manual). 

Space Odyssey is based on the G80 hardware that is used
in many other early Gremlin/Sega games, it might be 
possible that (in part at least) the pinouts described
here correspond to other games.

The cabinet wiring diagram isn't too clear as to what
each pin is precisely, it just runs off to the various 
components in the cabinet. I have added my comments 
in () brackets as to what i think they are :)

The audio looks like it is amplified seperatley on the 
Linear power supply board, so you'll have to bear that 
in mind when hooking it up.
