Hi All,
Recently completed a LISY80 mpu for my Gottlieb Hollywood Heat(system 80B). I am having an odd issue that I believe is related to using a PI 3B. Upon boot up, Phase 1 is as it should be, but when it gets to phase 2, the yellow led and red error led come on, and I just get random numbers and symbols on display. A few seconds later I have green led, and a red error led, but pin goes into attract mode, and you can play just fine with the exception of random numbers/symbols on display. I have tried 3 different SD cards, 2 different places for ROM image, uninstalled/reinstalled latest version of LISY 3 times, reprogramed PICs 3 times, also tried it on another System 80b game(Raven) always the same result. I will have a PI zero here in another day or 2, hoping it is just a glitch with the PI 3B.
