MVS edge connectors aren't fully JAMMA compliant depending on the model of the board.

1-Slot boards, use the JAMMA standard with only 3 boards being able to use stereo output although through the PCB pinhead connector not the JAMMA pinout (MV1, MV1-F, MV1-FS).

Multi-slot boards, use a different pinout based on Jamma commonly refered as 'MVS pinout', this has a couple of changes mainly because of the different nature of the boards, like having Stereo and the need to change the currently playing game title by pressing the 'SELECT' button.

Please refer to the MVS user manual of the specific board model, for a better understanding of the type of pinout it uses.

Like true JAMMA edges, the pad pitch is .156in (3.96mm). There are 28 pins per side (key included), 56 total.

Many harnesses use regular 56 pin board connectors which don't have the key to avoid accidentally plugging them backwards. Doing so will certainly fry the inputs chip (NEO-C1...), be careful.

Note that the G, I, O, and Q letters aren't used to avoid confusion with other characters.
