At one time I was starting to gather a list of all the sound board interfaces.
They are very similar and almost everything falls into 2 categorys. Some
sounds are triggered directly from a pin on the Cineboard. At some point
(the first game after SpaceWar) the found that there weren't enough pins
available so they used 3 pins to load a shift register and then latch
the contents of the shift reg. The outputs from this are usually all
triggers. It's really a big multiplexing problem because many games
use different pins for these functions. Then there's those other sounds...
