Hello everyone
I need some urgent help regarding wiring my X-Arcade to my coin mech.
I have hard wired my coin box wires to the coin buttons on the side of my X-Arcade. I used the info here to do it, which you can find at the end of the following page:-
http://homepage.ntlworld.com/chris.nightingale1/arcades/coinboxmainpage.htm
I seem to have hit a problem, which I hope somebody can help us with, even the author of this hack couldn't suggest a solution.. so hopefully somebody here can help...
I'm using an X-Arcade Tankstick, I used the hack as detailed in the above URL (via mono jack socket and plug) wired to each of the two coin op buttons.
Now onto my problem...
If I load up Windows Notepad, and drop a coin into my coin mech, I seem to get multiple key presses, e.g. I don't just get one 3 appearing, but I get a whole line of them! For instance, when I insert a 10p into slot 1, I get the following output:
33333333333333333333333333333333333333, etc.
The same applies If I also insert a coin into slot 2, I get the following output.
44444444444444444444444444444444444444, etc.
If I unplug the controller from the computer, and then reconnect the controller and do not insert any coinage, then I do not get 3 or 4's filling up the keyboard buffer.
Same applies under MAME32, I get multiple credits when dropping a 10p into the slot. The wires going from the coin op buttons to the solder tags on the coin mech I have checked, but still cannot find the cause of the problem.
I am using a basic 10p mech and door (the same as used in the Altered Beast and Asteroids cabinets) and no Sentinel unit. Obviously I am keen to find a fix to this problem, since the coin box will be incorporated into my Mame32 cabinet.
Thank very much for your help. I await your reply.
Regards,
Hercules

um...why go through all this work?
Just change your cfg file within Mame™ to accept a "coin drop" on your coin door (i.e.-- wire your coin door directly to your PC via a USB PCB like the groovy game gear econo board for about $20 bucks).

i dont know what is going on, but this should work just fine. i have an x-arcade in my cabinet and my coin mechs were wired to it as well. i didn't use minijacks or anything like that, i just made little Y adaptors with quick disconnects and attached them to the back of the buttons. after a while though, i got sick of having buttons for coins...i want to be forced to use the coin slots. so i grabbed an old PC gamepad, mounted the circuitboard to the inside of my cabinet, and soldered the coin mech switches to buttons 1 and 2 on the gamepad, and then told mame to use joy 1 and joy 2 for coins. that way they are independend of your x-arcade, freeing up another button that can be used for something else.
