Title: I-Pac problem#2 Solved!!!
Post by: Q*Bert_OP on August 04, 2005, 09:35:09 pm

My I-pac is giving all games 2 credits for every coin instead of 1. All games are set to 1 coin 1 play, please help me.

Sounds like you're shorting the coin 2 switch somehow every time you short coin 1. So you're simultaneously dropping coins in both slots and doubling up the credits.

Only coin 1 is wired

Then check your MAME config. Make sure coin 1 isn't triggering both coin switches in MAME.

Coin 1 should be the 5 key and coin 2 should be the 6 key. Make sure you don't have the 5 key mapped to both coins.

Open up notepad.exe in Windows if you can. Then drop a coin. What's the output? (You can substitute notepad for a DOS prompt or anywhere to see the text display.)

Do you have this wired to a real coin mechanism or a switch? A switch probably works correctly, but an old badly adjusted coin mech might be problimatical.

I tend to doubt it is the ipac. I think software or other harware is more likely at fault.

I had a problem with a few microswitches that would register 2 clicks every time I pressed the button.  Issue was internal to the switch.  I slowly pressed in the small actuator on the switch and as it was being depressed it registered one click (closing the circuit), then as I released it registered a second time (closing the circuit).  In notepad, instead of it continually repeating the keystroke as it was held down, it only registered once - once button fully depressed the circuit in the switch would become open.

Do you both (Qbert247 and joshbr7257) have coin buttons wired to discrete I-PAC terminal, or are you using the shift function to add coins?

You mean those aren't "1 credit" and "2 credits" buttons? j/k

it's hooked up to a coin switch.

i put a newer computer, and a newer version of mame in the cabinet, and all of a sudden , it does this.
