JAMMA to Pandora's box family edition converter cable
JAMMA is the wiring harness connector standard used on arcade machines.
This stands for Japan Amusement Machinery Manufacturers Association and has been around since the mid 1980s.
So you could imagine how many old school arcade machines use this cable and are starting to have their main board fail.
Whether your arcade machine board is playing up, has failed or you want to inject new life into it with a Pandora's arcade box, then look no further.
Yes, in order to connect a 40 PIN (Many refer to it as 48) board to your old school arcade machine you will need this adapter.
This has been engineered to match the new with the old so your data, joystick, buttons and so on will work once you upgrade to a Pandora's box.
The 40PIN connector is pretty standard on most non JAMMA Pandora's boxes whether its from 3A Games like the DX, Family range or a clone including 3D, 9, 12, 18 series and so on.
While this is a plug and play cable and we use it on our machines, please do your research regarding suitability to your machine/ setup.
