I tried searching for this but couldn't find the answer to my question.
I am about to buy a stripped out cabinet for my next project. It's just a generic cab with working coin mech. I believe the coin mech is a Mars 111 (but I would need to check this) which runs off a 12V feed (can get this from the PC). It's not one of the older mechanical mechs designed to just accept one coin. It will accept up to four coins giving different amounts of credits for each coin.
My question is will the JPac / IPac read and accept the signals being sent from the mech? Will it put 7 credits into the game if £1 coin is put in? (Assuming the mech is set up as such). Or will I need an older style mechanical coin mech that only accepts one type of coin? I would like to utilise the existing mech if at all possible though. (saves money

)
I'm wondering if the mech just sends one signal to the game board (or in my case the JPac / IPac) a different number of times for each coin and if the IPac / JPac will read them?
