Pinpoint 13311 Opto Board

Picture
This is the WPC era Type 1 flipper board.  It is used in games from Black Rose through Twilight Zone.  It is a direct replacement for the original, but has several design improvements.  It has a comparator circuit that is resistant to dirt build up, poor supply voltages and aging Fliptronics boards.  It uses a readily available optical sensor, not a special high current one that is getting expensive and hard to find.  This board does not connect the opto directly to the switch matrix either, making it much more fault tolerant.  Is comes with a one year warranty covering materials and workmanship.
