- Jamma fingerboards
-
JAMMA fingerboards are edge connectors with the same pin layout as JAMMA arcade boards. The idea being, you take a non-JAMMA arcade board (or in our case PC or video console) and 'convert' it to JAMMA by soldering the correct input/outputs to the JAMMA fingerboard.
It should look something like this:
After soldering the various wires to the fingerboard, it looks like this.
