I am want to add a mod to this game, I want to have mp3 sound bytes triggered using a Raspberry Pi. The sound bytes from the tv show will be used. This was done in a Visual Pinball version of Charlies Angels and I kind of liked it and thought it would be a good novelty to add to this machine. I have the Raspberry Pi and currently programming it to be capable of doing what I want. The question I have for anyone who understands electronics out there is can I use the current score trigger switches on the playfield to also connect to the Raspberry Pi computer without any problems to either system (Pi or Pascal MPU). I am assuming there is voltage going through those switches and I may have to run a parallel switch separate from the game but triggered by the ball at the same time. Any input on this is much appreciated.

Cheers: Brettski... :)
