The "SON SON" pinout must be carefully noted as it is rendered in a different fashion from other Capcom pinouts. The "SON SON" pinout is unique to my knowledge. I have not yet seen a matching combination. "SON SON" has its 2- player functions on the component side, and the 1-player functions all on the solder side. The same goes for the speaker. This is totally opposite of regular Jamma or other Capcom pinouts from its time. Also note that the pad-position numbering is from left to right (not in a column) holding the PCB vertically with the edge-connector towards you, and with the "+5" upwards. This means that where Jamma has "pin 1", "SON SON" has "pin 2".
