It was pretty cool Don.
The processor board was hooked to a set of breadboards
with a row of (I believe) opto-isolators, hooked to
driver chips, some sort of power fets possibly. Those
drove the movement through servos labled "BT ACTUATOR
9510" which were connected to short drumsticks (about
5inch long) which tapped on two symbols, a drum, and a
bucket mounted on a wood frame. The sound seemed
pretty good to me.
