MVS systems edge connectors dont't have a fully JAMMA compliant pinout.
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.
MVS pinout
Checked infos from [HardMVS.com]. The arrows represent the signal direction from the MVS board.
