Jamma->Mahjong adapter?

Post by Dilandau »

Does anyone have the pinouts to make one of these? I understand the power part but how to wire the 12 pin connector on the panel is what has me stumped.

Thanks

I searched and didn't see one, but I'll shoot him a PM and see if he still has it. Either way I'd still be curious to see how it's wired up.

Just my luck, he already sold it.

Here's two versions of the 56-pin pinout which is definitely NOT JAMMA compatible. The 12-pin connector presumably wires onto the 11-pins that comprise the keyboard matrix.

HTH, but if you have any other questions, shoot.

Cheers,
