MrQuan Posted November 10, 2007 Share Posted November 10, 2007 JAMMA is just a standard for arcade PCBs and their setups. You would need a JAMMA connector to plug into the game PCB, Power Supply with 12VDC, 5VDC, and -5VDC, Monitor that takes a R, G, B, Sync, ang Ground signal, Speaker for sound, a heap of switches (buttons, joysticks, etc), and lots of wire to hook it all up. As mentioned already, you wouldn't bother making a loom yourself, you can get them for about $20 or $30 ready to go. I'm assuming you're looking into a Supergun? These can be bought ready made also with video out suitable for a regular TV etc. It all depends what you're trying to do I guess. Link to comment Share on other sites More sharing options...
narf_ Posted November 10, 2007 Share Posted November 10, 2007 for a supergun go on ebay ive got one works a treat for $11.50 posted the other parts are easy find (megadrive controllers,computer powersupply) for plug and play you will need scart or the sg can be modded for s-video all up pricewise i built mine for under $50 and half of that was the scart cable as it was all i could find and didnt want to wait for a cheap ebay one to arrive works perfect for playing pcbs and testing i plan to later on box it and make it console style via neo-geo Link to comment Share on other sites More sharing options...

MrQuan Posted November 10, 2007 Share Posted November 10, 2007 well i googled supergun found nothing ive got a empty cab with all buttons and joysticks Ah ok, so you're looking to get a cab running, not a supergun. Straight up you'll need a monitor with chassis, arcade power supply, JAMMA wiring loom, speaker(s), and coin mechs. There are plenty of places that sell this gear in oz, check out the Links section or Trading forum. I've personally I've only dealt with ozstick and gamedude arcade, both are coolio. :) Link to comment Share on other sites More sharing options...
Viper Posted November 10, 2007 Share Posted November 10, 2007 hi i was wondering if anyone has any info on how to set up a proper jamma from nothing just parts and what parts i need Mate, JAMMA is just a wiring standard, nothing more. It simply dictates which connections in the cab go to which pins on the fingerboard for the arcade PCB so they were able to use the same cabinet with different PCB's. If you want to get your cab running PCB's as JAMMA and all you have is a cab with buttons/sticks then as mentioned above you are going to need the obvious monitor/chassis, plus: - a stepdown transformer (convert your 240V AC mains power to 110V for the monitor) - wiring harness (as Pinny advised easier and cheaper to buy than to make) - power supply (really is just another transformer, brings your 110V down to the 5V and 12V required for the PCB and other cab bits 'n pieces) - speaker(s) and associated wiring/controls - coin mech and associated wiring - service button - degauss button (depending on your montor/chassis) - fluro (if your cab has a marquee and you want it backlit) Probably other stuff too.

Johns-Arcade Posted February 26, 2008 Share Posted February 26, 2008 If you look at the Jamma pinout it tells you. Here's a link. http://www.jammaboards.com/jcenter_jamma_pinout.html Regards, Johns-Arcade. Link to comment Share on other sites More sharing options...

spot Posted February 26, 2008 Share Posted February 26, 2008 do more reasearch then. if you don't understand a basic pinout, your best bet is to learn more before doing anything. the jamma pinout above shows what wires are going to where - most will be hooked up to the ground loop.

elkor-alish Posted February 26, 2008 Share Posted February 26, 2008 do more reasearch then. . Ditto. Coolspot, I was in the same boat as you a month ago. I discovered most of what I needed to know from reading some of the manuals for the games I liked. Most of it's just crap about the game but at the end they have the schematics for the game pcb. Have a good look at these and I'm sure you could work it out. Alot of places that sell Jamma harnesses have the wiring labeled so its not that big of a deal anyway. Research, research, research.

coolspot Posted February 26, 2008 Author Share Posted February 26, 2008 ive been looking for ages all im asking is what wires go where as mine on the harness is written in chinese Link to comment Share on other sites More sharing options...
narf_ Posted February 26, 2008 Share Posted February 26, 2008 look for the pinouts on the net these will tell you count the pins from 1 to 28 if it isnt numbered you will see a blank with no wires 7 in from one end this is pin 7 it is a key and isnt used so the shorter end is pin 1 if that helps Link to comment Share on other sites More sharing options...
Syzlack Posted February 26, 2008 Share Posted February 26, 2008 Thats the thing i don't understand them. Its not too difficult, Did you look past the diagram?:unsure I tells you step by step pretty much, There is two sides to the jamma harness Solder and parts side. Have a look at the link again, it should make sense:023: Buy a complete harness, dont bother wiring the whole thing yourself. Link to comment Share on other sites More sharing options...

Arsenic Hipster Posted February 26, 2008 Share Posted February 26, 2008 So if the lights start to flicker it's not because someone forgot to turn off the compressor in the shed, it's just you switching you cab on. It shouldn't be that hard just pay attention to what wire goes where, once you've hooked it up go have a Milo and a Timtam. Then when you come back check it over again before plugging it in and throwing the switch. That way you should spot if something is wrong before it fries some components.

gints Posted February 26, 2008 Share Posted February 26, 2008 this is in a different section of the site linked above, its a good diagram i suppose because it's not just a pinout but shows the button wiring and stuff if you're not really down with it. http://www.jammaboards.com/images/JAMMA_Functional_Connections.gif Link to comment Share on other sites More sharing options...
