I picked up a Mortal Kombat 3 today, it is in a midway universal cabinet and looks to have been converted from something else. When I turn the game on, all I hear is static, and it doesnt fire up. When I was troubleshooting, I put both of my working mk2 boards in and neither one would show on the monitor, but if I put in a regular jamma board such as tmnt, if comes right up. Anyone know why this is? Am I missing something here? Thanks for your help!!!!
