Was searching around and could not find exactly what I was looking for. I am in the process of building a bartop and was thinking of having a small coin mech in it. I found this on ebay and was just wondering if anyone has made this work with MAME and how do you?
http://www.ebay.com/itm/SUZO-HAPP-25-Roll-Down-Quarter-Acceptor-Coin-Mechanism-/300940150392?pt=LH_DefaultDomain_0&hash=item46116e4678 (http://www.ebay.com/itm/SUZO-HAPP-25-Roll-Down-Quarter-Acceptor-Coin-Mechanism-/300940150392?pt=LH_DefaultDomain_0&hash=item46116e4678)
Any help would be appreciated.

Just like a regular coin door, it'll have a switch at the bottom with .250 QD contacts labed NO, NC, and COM.
Common is your return path (or Ground).
NO is for Normally Open contacts, NC is for Normally Closed. You'll be using Normally Open.
One wire from Ground on your Encoder goes to COM. The other wire from the COIN or button input goes to the NO connection.
When a coin is inserted, button is pushed. Viola.

The related Suzo-Happ page is here (http://na.suzohapp.com/all_catalogs/coin_doors/40-0012-00).
Pretty sure that you can see the microswitch lever wire in the lower left corner of this pic.

Also, there's a PDF here (http://na.suzohapp.com/images/pdf/roll-down-acceptor-adjustment.pdf) for adjusting coin sizes.

Thanks for the explanation. Now is there a way to have any coin acceptable? or is it one coin specific? I am going to have a button for coin up on the bartop but this will be like a piggy bank with a reward idea.

Most coin mechs are going to be designed for a single coin type. The one you linked will only work with quarters. It is possible to buy a coin mech that takes more denominations

But I dont' think that would work directly with MAME. Mame is only going to know that the coin button was hit, not how much money you threw at it. With that fancy coin mech it would be possible design circuit with a micro controller to count up the money that was put in and then when it hits a certain threshold the micro controller sends a signal to the button interface board's coin terminal. A little complicated if you don't use micro controllers(complicated even if you do), but it could be very cool.

See the PDF I linked earlier -- it is adjustable for tokens, too.

IIRC someone around here has modded another type of mech to be non-selective on size.
Not sure if this specific mech can be modded like that, though. :dunno

Edit: If you want to use the Adafruit (CH-926) mech that Blacketj linked with an IPac or similar encoder, check out this thread (http://forum.arcadecontrols.com/index.php/topic,122129.msg1296047.html#msg1296047).

I've successfully installed one of these multi coin mechs in a cabinet I built. Works great. You do need to power it (i think 12vdc which I tapped off the power supply. ) I programmed it so it accepts quarters, nickels, dimes and pennies. Each coin can have its own different credit value. You do need a resister to bring the trigger voltage from 12 to 5 volts.

That is more what I was looking for. I will probably just buy the one I first listed though, I just know my kids will throw just about anything in there.
Plus this is my first build and I just want something playable and looks nice, I have a million other ideas from this forum that I can throw in other builds. But thank you all for your insights.

I used them on a build before, nice mechs. You have to use a 5 volt Zener diode between ground and coin signal or you could fry the I-PAC.

michelevit:
How did you program/configure your coin mech to accept quarters, nickels, dimes and pennies? :dunno
I'm trying to accomplish the same task for my son, and create a "piggy bank" of sorts for him.
Please share your technique! ;)
Thanks!

You program the coin mech directly using buttons located on the back of it.
The only downside I can think of is when the cabinet is not powered all coins will be rejected.
Good for an arcade, but bad for a piggy bank.
here is a good video which details everything...
SparkFun Coin Acceptor (http://www.youtube.com/watch?v=Dyun1xjKqc4#ws)
start watching @ minute 4 which describes the pulsewidth type coin mech.
i love the coin mech and recommend it highly.
