Hi Dave. VERY cool to add this to the Zaccaria arsenal! I want to support the project but I really can't stand the original electronic squeaker box sounds. Really, really dislike them.
Sound is the most important element and for EM's in particular... it's just gotta be chimes for me.
In my Queen's Castle I was planning to wire a Gottlieb chime box (or bells) and have it triggered by the scoring relays, same as most EM's. Though on games like Combat the sound board also makes electronic explosion sounds. Would be cool to keep the special sounds and bypass the default scoring bleeps and bloops for a chime box.
Two of our local "VECTORIANS" have a Combat. Let me ask them. Also might as well count me in for a flasher replacement... because ya never know...
