SEGA NAOMI Auxiliar coin door board - Help

[baritonomarchetto]

Hello guys,

I have my brother's Crazy Taxi in my "arcade room" that stopped working after years of use without any issue.

It "went black" after toying with the coin door auxiliar board and unfortunately I am not able to find any info about this board. Not too complex, but having the schematics or infos would help me figure out things way faster.

I also have an unplugged connector that fits with those two IDC sockets but i don't know where it should go.

Attached is a picture of the board I am speaking of, just for reference (pic was stolen from the net, but mine looks the same).

Any info about those DIP switches, that status LED (pulsing in my unit) and general wiring would be much appreciated

No love for SEGA NAOMI?

This hardware is not something I am used to, unfortunately
