It was more to do with taxes according to an old operator I talked to. Destroying them netted them more than 50-100 or whatever for the cabs from tax write offs. But I don't think there was a time in the 80s when they couldn't sell them. If you priced them at 50 bucks a pop they would fly out the door. People have always wanted arcade games at home and those people didn't pay attention to any sort of crash.
