sorry its taken so long to reply but I've ben busy with other things and this arcade plan had to take a back burner. I would be overjoyed if you can help give me a simple wiring diagam to get this working. I have tried the so called local 'eletronics experts' here but as soon as I tell them I DONT want the coinslot attached to a timer board they simply dont understand what i mean ???. Also does not help when I'm not a local here and tryig to get myself understood is very tricky! I tried the jukeblaster idea of using the coin counter wires to trigger a 12v relay but there does not seem to be enough voltage to trip it. so that failed.

Please help. I would be so grateful :applaud:

If you're using a 12v coin recognizer to drive a 12v relay, you don't want the 5v Zener diode in the diagram above.

Wire it like this with an optional 12v snubber diode (there might be one built into your relay -- you'll need an external one if you have relay "chatter") and the "ZD encoder" wires connected to the gamepad.



If you're not familiar with relays, here is a tutorial.   ;D

ok

wiring the relay directly to the coin signal and ground seems to work but now I have another issue.
The coin slot thing only sends a 160ms pulse but the program i am using  with it only polls the joypad (which the coinslot replay is attached to closing the "select" button") every 500ms. I need some sort of circuit that will hold the pulse for about half to a full second.

any ideas anyone?

thank you

Since the output goes high when triggered you will need an inverter on the output to get the opposite effect.
An inverter is typically a single gate the produces a NOT signal.  Should work at 5V logic levels.
