How to add a credit using the coin return button on a JPAC?

[JonN]

Hi all

I have a PC running MAME in my cab with a JPAC for the controls. It's a Unigame cab with a Philip Shefras Spares blue board coin mech (schematic here - http://www.swallowam.co.uk/credit.php). I currently have a microswitch that i click to simulate the coin insert in order to add a credit, but I'm wondering if there's any way of wiring it so that the coin return button on the outside of the cab can be used to trigger it instead? From the looks of things it's purely mechanical, with the board only used to calculate the sum of the coins inserted, but hoping I'm wrong!

Interested in your thoughts!

Cheers
Jon
