I was recently handed down a stunt cycle that had been sitting for years. It would not function at all and only had 3.6 V after the regulator so I replaced that and now I'm getting a good 5 V. Now the game starts up and coins up and everything is good until the bottom of the screen where the buses take up the entire bottom row. They will not reset and the bike crashes before it even gets to the ramp every time.. with my limited experience and research I'm gathering it is an issue with a TTL chip. Anyone have an idea of which one could be causing this? Are the 74 LS series compatible?
