Feel free to dump questions on us anytime. That’s why we’re here! As for your questions, this might require some soldering or might not depending on what direction you want to go. We would recommend getting some terminal connectors to put on the ends of the wires coming from your harness so that soldering is not required. For the coin mechanism, you will want to use the coin switch wires and a ground wire to get it to coin up correctly. If your cocktail doesn’t currently have a test and service switch in it, you can always buy the entire bracket to put in your cabinet then just wire it up.

We have also featured your question on episode 24 of our Q&A podcast. Please listen to it for more of our thoughts on your question. Thank you for your question and good luck with your future repairs.

I need to install a Coin Mechanism and a Test/ Service button on a cocktail table of mine. Now, thanks to your JAMMA table I know WHERE to put them.

But I have no clue as to what I need to put on the jamma harness in order to get things going. Does this involve soldering, or is there a special kind of plug, wire, adapter that fits right on the pins?
Also, assuming I can get any of that figured out, I noticed that there’s 3 coin pins: a coin counter, coin lockout, and a coin switch. Which would I connect the coin mech to?

I’m sorry, I didn’t mean to just dump all of these questions on you, especially since you’re probably not here to just answer everyone’s little questions. But if you know of anywhere to find the answers, I’d be most grateful. I looked through your other posts, but couldn’t seem to find these specific answers.

The JAMMA and Mr. Do! harnesses have the same amount of pins but a different layout on the pinouts. For example, the video output on a JAMMA harness is located at pins 12, 13, N and P. On the Mr. Do! harness, the video output is located at pins Z, a, b and c. Therefore you CANNOT hook a JAMMA board directly up to a Mr. Do! wired cabinet and expect it to work. You would either have to rewire the cabinet to JAMMA or buy/make a Mr. Do! to JAMMA adapter. An adapter can be purchased from Arcade Shop if you are interested in that. You should not have to buy a new power supply if the one in the arcade cabinet is currently working.

We will also feature your question on episode 22 of our Q&A podcast which should be posted soon. Please listen to it for more of our thoughts on your question. Thank you for your question and please keep us updated on your repair.

Yes you can but you will need to get a Mr Do to JAMMA converter. You can get this converter from Arcade Shop Amusements. Here is a link to their JAMMA converters section: http://www.arcadeshop.com/parts.htm#JAMMA. Just scroll down on the page until you have located the Mr Do to JAMMA converter. That should be all you need to start playing JAMMA games in your cabinet.
