Whitewater is my favourite WPC game and i now own a nice one that i've bene restoring over the last year or so (when not making pcbs). I decided to make a new waterfall chase lamp board as mine was missing and I wanted to make some improvements over the original design. The main improvement for my board other than bulb usage is the fact the board is now more 'intelligent' than originals. You no longer have a problem with the lamps locking on solid at boot in random patterns to when you enter the test menus. This puts unnecessary load on the bulbs and drivers at certain points and also looks a mess. By utilising a design that can read when the cpu control stops the board can disable the lamp string and then re-enable once signals start up again. This in my view is what Williams should have done and intended for the design of the topper in the first place.

See here for a quick test video showing then lamp string being enable and disabled at certain points. ie at boot the full lamp string is off until the playfield GI turns on
