Got a particularly problematic Life Force PCB here. The 68000 keeps getting its reset line pulsed and the video keeps going out of sync and cutting out. A Mask ROM pertaining to data common to Life Force and Salamander is confirmed dead.
Several of the 74LSXX chips related to the 68k's 9MHz clock signal and the graphics chipset have been replaced. The 68k's clock oscillator has also been replaced. Issues still persist. Any ideas?
Power supply is ATX, 5v is 4.86 on average.
