Connector - ElectrocoinThe Electrocoin standard was introduced before JAMMA(Japanese Arcade Machine Manufacturers Association)to allow various games to be connected to genericcabinets such as Silverline and Goliaths. They use the same 28 way connector,but the designations are different. Pins 16 and 18 were 3 player and 4 playerstart buttons, and were superseded when 3 button games became popular. Pins 14and 20 were free, but were used by us to allow for easy servicing of games.28 PIN UNKNOWN CONNECTOR on the arcade machine Pin | Description |
