Yes it was a very long time ago. I think it was when the colors were corrected. It went round and round on how it was supposed to behave. I believe the wording in the manual made it confusing. I new when the bug was closed at MT, that it still wasn't right. I didn't have the proof though. I've discussed it with Rohan who owns an original upright. He confirmed that it still wasn't right. He kindly uploaded a video of the gameplay.

I remember playing it at King's Plaza in Brooklyn around 1980. It was much more fun than the Hustle machine behind it.
