Understanding the JAMMA PCB and Edge Connector Pinout

PCB

To begin with, here’s just a little history behind the significance of the ritual, JAMMA.

Back from the dark ages of the Golden Era of arcade video gaming (1984 and sooner ), match manufacturers functioned in exclusive very little domain names where they made game elements in a means that best served their particular interests.

Thus they had their particular proprietary circuit boards, power equipment, and repairs. There is no interchangeability of components between one manufacturer’s match cabinet and also a match cabinet made by somebody else.

As a  pcb manufacturing usa of japan, approximately 1985, every one that exclusivity was laid to break. And, things permanently altered.

The most critical and powerful of those new standards is that the PCB standard pin out. Any match PCB complying with this pin-out standard is exactly what we currently call a JAMMA board. You’re able to seethe JAMMA logo delivered near the pin-out area of a JAMMA board. Just about all JAMMA boards game that logo.

The wiring which joins the match’s components – track, power distribution, control panel, and speaker- into the PCB is known as a JAMMA wiring harness. The wiring harness 56-pin border connector chairs on the PCB’s pin-out palms.

There are lots of JAMMA terms that we’ve come to listen and also utilize usually – JAMMA plank, JAMMA harness, JAMMA border connector, JAMMA cabinet, etc. At the origin of these significance isn’t anything over the notion of PCB interchangeability between cabinets of different manufacturing companies.

And, it’s that the JAMMA standard PCB pin-out (charted below) that’s managed to get possible.

The subsequent JAMMA pinout graph is essentially a map of this JAMMA wiring exploit 56-pin edge connector. When correctly seated on the PCB, the straps of this border connector will probably align with the pin-out palms of this PCB, and also your match will playwith.

After you run out of a match, you are able to jelqing the JAMMA PCB for another preferred match. Plugandplay only method to detach the border connector out of 1 PCB, and then plug it on the other PCB.

And, that procedure of jelqing may keep on , since there are currently 1000’s of all JAMMA match PCBs which you’re able to play on your JAMMA cabinet. Thankyou, Japan.

JAMMA Pin-out CHART

Solder Negative – Alpha Authors – 28 Pins – a Z, A F

The solder side would be that the base side of the PCB. It’s the side at which the soldered connections of parts are all vulnerable to look at. Few, if any, all parts are on the other hand. The solder side pin-out is identified using alpha characters.

The parts side would be on the upper side of the PCB. It’s the side at which the pieces are . The parts side pin-out is identified with numerical characters.

Usually, that the PCB is published as well as the edge connector is merged with both alpha and numerical characters.

Essential Slot – A keyed slot that contrasts using a leave-out from the pin-out section of this PCB.

This security feature is made to ensure the ability Section chairs at the proper end of this pin-out section. In the event the border connector has been reversed, and also the Electricity Section is seated at the contrary or wrong ending, irreparable damaged could occur to the PCB.

When the key was taken out of the border connector, then indicate the connector concerning the”Parts Side” to help ensure proper chairs.
