This info was obtained from an original Gee Bee
service manual.

This manual was entirely in Japanese. Not being 
fluent in Kanji, i couldn't say precisely what each 
pin function is. However, they use numbers like 
everyone else, and can still draw accurate cabinet 
wiring diagrams, this means that the most important 
bits of wiring up a board can be accomplished.
What i call 'optional' pinouts for controls and 
coinage are guessed at here, go careful, for the most
part i amd confident they are correct.
