I have a Gaplus cab and have a question about a couple of the plugs. There's a 6-pin and a 3-pin that plug into the board. The 6 pin is for the monitor (I've used it to test other PCB's), but I don't know what the 3-pin is for. I was hoping it was +5 and +12, but metering it, I can only get 5v reading. I have a JAMMA cab adapter they plug into (but that doesn't really matter for my question). Both plug into the adapter, but the adapter works on my 48-in-1 board without the 3-pin being plugged in. What is the 3-pin for? I'm including a pic of the adapter for reference (from jammaboards.com)
