Wiring harness for CHAMMA type game boards. This is the modified China version of the "Japanese Amusement Machine Manufacturer Association" design know as JAMMA. In the 1980's and 1990's most of the arcade game board manufacturers conformed to this wiring pattern and connector plug type. This one has all the .187" connector lugs to plug onto the control panel switches and joysticks. Has all wires labels on the 56 pin connector. This has every wire populated that can be used on a Pandora's Box type Chamma connector. There are more connections on a CMAMMA board than on a JAMMA.
