Install jamma board

What is less neat is many used cabinets have been a little abused by their previous owners. Damage from players and hasty fixes may equal some pretty insane problems with the hardware.

In order to use the cabinet for JAMMA games, one must replace the connector, or even rewire the entire cabinet, being careful to match each wire to the proper place on the connector. It was totally unlabeled - the pen markings are my attempt to make some sense out of the board.

The "CSI: Arcade Operator" portion of our program: from the burn marks on the GROUND connector, we can infer that the traces and board were not rated for the amount of current for the entire machine running through a single trace oopsie!

There were four GND connections, but they weren't connected to each other, and from the look of things all the power for the entire board was going through this one connector. The board connector fried, and rather than connect the other grounds, the operator connected another single wire to the ground, likely because they didn't know anything about how electricity works or Ohm's Law or the Joule effect - basically "if you put a lot of current through a tiny wire it will melt or catch fire.

The short version: I have to rehabilitate this cabinet to get my game working. I may as well get it working in a modern way that can use other games, don't you think? Question 1 year ago. Question 2 years ago on Step 3. I hAve a golden tee2k i bought a replacement harness from arcade shop. Question 2 years ago. Can I wire a independent 4th button only for player one to be able to operate the confirm.

I tried just hooking a switch but didnt work. Now considering addimg say a 5vlt signal. Will this work just hooking to c pin and 25 pin or do i need ro make it all fancy loke the rest. Ive attempted to add a photo also. Looks fairly proper but i am nowhere near an electrician. By monkeywidget Brian Doom Follow. More by the author:. About: Indie Film! Art science!

More About monkeywidget ». JAMMA is an industry-standardized layout for arcade game board connectors. The pins are labelled with letters and numbers the component side is all numbers the solder side is all letters not including "i" or "o" since those are similar to numbers starting with capitals ending with lower case Some notes on the pinout - the connector has a "solder" side and a "component" side. The notch makes the connector asymmetrical so you don't connect the board upside-down.

Some connectors have a plastic piece here. Attachments jamma-chart. These days, you can buy an entire harness which is pre-wired into a "loom. If you are wiring your cabinet, at some point you will have to know what every wire does. This is easier than it sounds - you literally follow the wire from where it starts, in its known position on the connector, to wherever it ends. To make things easier to figure out, I: labelled the groups with blue tape and a maker put spiral wire wrapping on the larger bundles - this is a plastic spiral you can buy at Radio Shack to hold wires together Notice my harness is a bit quirky - there are some deviations from the standard.

See the big gap next to the white speaker wires? Now that we know what all the wires are, the rest should be easy - we just connect everything to the proper place. Log in. Search only containers. Search titles only. Word Count:. Search Advanced search…. New posts. Search forums. Install the app.

According to the manual I need to press the test button to get into the Bios if you will. Can anyone tell me the correct way to install the test switch on a Jamma cab.

I understand that it is located on the 15 pin on the connector but my connector has no wire in this slot. Where dose the other end go? Ground, power, or to the opposing pin? I have found nothing on line to tell me such. Also any suggestions on a print publication to assist in arcade repair would be greatly appreciated.

First of all, welcome. Yes, the other wire goes to ground. Not sure what type of multicade board you have, but if you have a in-1, in-1, or in-1, you can put it into the 'bios' by turning on switch 4. If it's a different kind, then it might not work.

And you can either add a button inside the cab for test or service, or multi-use a button on the CP, as long as it's not active during gameplay Well, as I've had this happen on some cabs, I'll tell you what i did to fix it, and you can see if it is relevant to your issue. Look at the coin switches of both cabinets and compare them. You'll probably find that they are wired differently.
