Hi,
I have recently brought a Sentinel coin mech from ebay.co.uk for
-
I started looking into using one of these on a mame cab but got distracted. They do need a credit controll card to work. it's what translates the different signals made by different coins into credits, and stores the credits, but I dont know if you could maybe bypass that in a mame system and just have the sentinel's signal to the credit controll hijacked to a transistor which could close the circuit for the coin buttons.
If you figure it out I'll be keen to see how you did it. I'm sure there should be a way.

That's overkill for MAME. For 6 p you could have bought a brand new "regular" mechanical coin mech.

you need something like a klingon credit board,they are available from suzo and brent electronic in the u.k(about 25 quid) but you may be able to pick up a second hand one from an amusement operator near you
you can bypass using a credit board but you need to be experienced in machines really or you will blow up the coin mech and/or power supply

Hi there, what is used to to detect if a coin has been inserted ? If it's a microswitch & an Ipac you should just be able to wire them together. For the coin insert light, you can wire power from a spare molex connector from your PC power supply.
You think you have problems, i wish my coin door was from the UK but alas my cab is from Italy originally (puchased here in the UK though via eBay). I'm having to have custom coin inserts made for me so they show UK coins i.e 10p , 20p &

Thanks for all the replies
Hopefully in the next few weeks i will be starting my cabinet and/or control panel build....and hopefully it will have a fully working coin mech.
I'm thinking of using a keyboard hack for the control panel aswell as the credit input.
If I did purchase a klingon credit board (or any other board for that matter) would the wiring involved be pretty straight forward?
As for the power supply to the coin mech,
Anyone have any ideas of how would i go about hooking it up to a temporary power supply to see if the mech/bulb etc works?

you can get a coin mech to accept using just +12v and common,if you look at the label on your mech it should numbered 1 to 16(depending on version),its the pinout of the plug
1-coin common
2-coin 1 accept
etc
you will see +12v(might say Vcc) and common,these need to connected to allow the mech to accept BUT sentinel mechs were bloody awful to be honest and even when they accept they don't always credit-i think you would be better off just getting a mechanical mech,if you go ahead with this mech then i would strongly suggest getting a klingon credit board-the wiring is simple and they plug straight on to the sentinel(you only need 3 wires +12v,common and credit line/coin switch)
you can use +12v and common for your coin bulb(as long as its a +12v bulb that is)
you can pick 12v and common straight up off a standard p/c power supply(yellow +12v,black common)

it seems i will be best to buy a new coin mech etc.....any recommendations? (please provide supplier website/details and product name)
i will probably leave the sentinel coin mech till i have more experience
-
is the mech to be mounted on a standard coin door or are you going to mount in a wood panel?
