I bought an original Track and Field cabinet that was converted to Jamma. I am in process of converting it back to T n F. I made a harness, following schematics, and installed a track and field boardset. When I power on, it seems that I have a monitor sync issue, because of garbage on the screen. I assume the monitor was the original T n F monitor, because the wiring had been modified. Does anybody know if the sync for JAMMA is different than the non-Jamma sync?
