Coin Counter Question

paigeoliver:
I have the general idea, but I don't seem to understand how to wire it without shooting 5 volts down the input line for the coin switch.

Ken Layton:
Randy Fromm has various coin meter hookups on his super secret tech page.

As soon as I can afford it, I am going to get some tapes from Mr. Fromm.

TheNasty: Thanks a ton for pointing me here. I had done some searching and even started a thread on this subject, but never got this far.

I wired up my coin counter, as per the sketch, and it works fantastically!

However, I'd like to try one modification. I have two coin switches in my coin door (and actually 4 credit buttons on my panel 2 of which are wired to the coin door).

Anyways, I want to increment the counter on all 4 inputs. Right now if I wire up the Meter to all 4 grounds then when I hit player 4's coin switch all of coin switches fire! These 4 coin inputs *have* to be separate for games like The Simpsons - where there was no start button, you put a coin into the slot of which character you wanted to play.

I'm looking at the sketch and I think what I need is some sort of one way electrical component between the meter and each coin switch. That way when I press the player 1 coin button, players 2, 3 & 4 do not fire, but the meter still increments.

I've attached an updated drawing. Is there such a "Gizmo"?

Is there another way to do this that I'm not realizing? (Ipac reprogramming?)
