This board is a complete redesign of the 3 opto PCB (also referred to as a ramp opto board) used on many Williams WPC pinball machines.

The newly redesigned board has a number of significant advances that improve over the original:

• Status LEDs give full diagnostics of each transmitter and receiver!
• Lower current consumption and less heat, for longer life.
• User serviceable with transistors that are replaceable with thru-hole equivalents!
