Have a OST trigger board set developed by @dumbass on pinside.
Suitable for Williams system 3 - 11b and early Data East Games. Protects the driver board and coils from damage by just sending out a single pulse to fire the coil instead of how long the switch is held closed for. Has diagnostic led which tells you of a permanently closed switch.
