Does anyone know if Area 51 site 4 need a special dedicated jamma harness for it to work or a regular jamma harness is ok? I bought a51 site 4 on ebay with hard drive and plug it in my regular jamma and it doesnt work. just a loud hiss static noise and a blank grey screen. any info would be appreciated.
 
The jamma should be the same but you need to have power to the hard drive and i power to sothing else if i remember right.. I will take pictures of mine to night for ya.
 
There is a connector from the PCB to the hard drive for power and an IDE for data. You also need the -5, I believe, so if your harness doesn't have that, it won't work.

And of course, the guns will have their own connectors that connect to the game pcb...
 
Regular jamma but it does need a solid 5.1v...do NOT go much higher as the Atmel chip is very sensitive.

The on board amp is a little noisy when nothing is going on.
