I just got this board which I bought from TNT Amusement.
It's supposed to be TOKI, but I'm a bit confused to how to wire up this thing.
Are there perhaps anybody here who know this board and/or can guide me trought the pinouts so I can frankenstein a harness to fit a JAMMA harness perhaps?
I have a cocktail cab which currenty has Tetris Jamma board, but I would like to have the option to swap between these two games once in a while.

The seller also mentioned there was a humming sound during play.
I asked if this could be a "-5V issue", as to refeering to that toki pcb uses -5V for sound also. The seller replied he did not know, which could be a smokecloud answer turning out to be "NO, it's just not 100% condition".
Anyway, would be greatful for any help there might be!
