TMNT Credit/Logic Board

[StuartM]

I have a TMNT 4 player cabinet,

The coin mech that is installed is a MARS??
Unsure if its working correctly or not. Tried 2 but both
offer similar faults.

To left left of my machine is a small logic board that the coin mech & player start buttons are wired to.
There are 2 sets of dip switches on this board.

Can anyone offer any info about this board & what the dip switches do.

I could test them in turn but means reinstalling the original game board,
At the moment it is rigged up to a pc for mame.

I have left all original wiring intact so can easily replace the cab back to original game.

Any help with this much appreciated.

I have been told that the 2 player version does not have this board, so I think its only because cab is 4 player version. Just curious about what the board controls.

No start buttons wired to Jamma harness.
