Wondering if I have a chance at getting the sound to work on my Cylone. I just bought the game in Montreal from Alloutte Amusements as a fixer upper. Tried it out at there location, it booted up OK but no sound or screen displays. Bought it anyways because the playfield was pretty good condition. Brought it home yesterday and have been going through it very carefully now !! It is amazing what you can easily overlook when trusting that you are getting a complete machine. Amongst other things. It turns out it does not have the original System 11B CPU board but instead it is a system 11A from a Pinbot. The sound card is the correct one for this system 11B cyclone. Is there some way to make the sound card work with this system 11A CPU board ? I looked online but only found that the system 11B CPU board (which I don't have) is compatible with all other system 11 systems . But I am stuck with a 11A CPU board. Any help would be appreciated.
