Drawing of board on 8-5 Schematic on 9-8 Player display schematic on 9-7 They also can be used in the S+ as progressive driver board. If you have the Liberty Bell S and S+ slot book the schematic is in there. The parts on the board also can be used to repair the S+ player display. I built one from the schematic in the book I mentioned and it worked. uses common cathode LED's In fact before I built one I tested the idea with a spare player display as a test progressive display just connected it to the top box connector. Looked funny with the value split between the Winner paid and Credits Window though. I felt comfortable experimenting to see if it would work, as some say kids do not try this at home (my disclaimer) To use them as a progressive you need the LED board 7 or 8 digit uses same LED display as the newer S+ progressive driver board. John also has the newer progressive drivers as well. I not sure if he has any of the LED parts for them though. Title: Re: What are these for ?

Thank you so much for the good answers. I think what you're saying is that these will drive the 20-pin progressive LED displays, but will NOT drive the 20-pin progressive dot matrix displays right? Also, the LED test display you made...you stuck it behind the reel glass where "Winner paid" and "Credits" is? Title: Re: What are these for ? Post by: Foster on December 20, 2008, 05:49:31 PM No it was a temporary test, I was just testing the theory that the parts used on the Player display and the S Slot progressive driver are the same and would work as a progressive driver board
Yes, the 20 pin 7 segment LED's common cathode right hand decimal .43 inches high. For those interested grab one of the Liberty Bell S and S+ slot book from eBay if any are still on there. |
