Exidy 440 to Jamma Adapter
My portable test rig is made with a Jamma setup in mind. Jamma, being a universal setup, has
just about everything any game might need. Then, I just use "Game X" to Jamma adapters.
One of those adapters is the Exidy 440 to Jamma adapter. Because this is just a test bench setup
I do not have the connections for the optical gun or the monitor on my adapter.
Since the boards are normally stacked on top of each other, an extended ribbon
is needed to get the boards to lay flat for testing.
Below is a .pdf file of the pinouts for the Exidy 440 board. All the pins are referenced
as you are looking at the boards. The connector label should be on the right. Pin 1
is closest to the connector label.
