The Ocean Pearls input/output board utilizes 5 input IC's to control all inputs used within the game. In Ocean
Pearls, FOUR of the FIVE IC's are used, those being U08, U09, U10, & U11. The remaining IC at U12 is not used
to control any input function. This IC can be used to replace the other IC's should they become corrupt.
