Well I would be interested. How may Bally games does this mod work on? If someone built these I would buy one or more.

Ok I want to test the waters. I took a complete set of clear plastics out of Fireball to a shop and asked for a price for 25 sets. I did complete sets and not just the two pieces that break because my guess is most Fireball clear plastics are yellowed like mine and the difference in cost was only about $15. Why not get a complete set. You will need to transfer the small bell shaped stand offs but a post in this topic covers how to do that. It does not look hard once you know the tricks. If someone finds that before I do please repost that here. Cost for the 6 piece set will be $50 plus shipping. I'm new at this so I'm not sure how to deal with the shipping part. The plastics will be made of a material that will stand up to any type of shipping so it may be possible to use bubble wrapped envelops. Not going to get rich with this project but it should be some fun helping out other Bally and Fireball Fans. If this works out I may do other Bally games from this time period. Let me know what you think and send me a PM if you want to get on the pre-order list. Thanks

First, I'm almost sure the balloon feature uses a step up, reset type stepper unit. I have this game but it is in storage. Second, I hope one day someone makes about 50 on these add a ball units. They would sell fast as they fit a number of Bally games. I think the add a ball units could sell for at least $50. Anyone interested? I would do it but I already have a lot of unfinished projects.
