JAMMA to Nintendo Cabinet Adapter

Allows you to play your JAMMA games in a Nintendo cabinet.

The original Nintendo PCBs output inverted video signals and require an external sound amplifier, while bootlegs output normal video signals and have an on-board sound amp. The cabinet, depending on what game is inside, will likely have the audio amplifier and the original inverting monitor, but not necessarily.

As a result this adapter includes a sound attenuating circuit and a video inverter. The low cost, high speed video inverter can be disabled on the adapter making it compatible with both original and modified cabinets via a couple of jumpers.

The signal DC offset for each color (Red, Green and Blue) can also be adjusted to display properly on am inverting monitor. The video inverter is a simple linear design for the best possible picture at a low cost.
