I am in the process of changing out the system 4 board in my Flash for a P-roc programmable board. I am going to modify the rules for Flash, and would like to keep using the original sound board. As I understand it, there are 5 coils that serve as inputs to that board.
My question is about how the sound calls are actually made from the coil drivers to the sound board. Are the 5 inputs treated like a 5 bit word?
