CP System
The CP System II consists of two separate parts; the "A" board, which connects to the JAMMA harness and contains components common between all CP System II games, and the "B" board, which contains the game itself. The relationship between the "A" and "B" board is very similar to that between a home video game console and cartridge. CP System II "A" and "B" boards are color-coded by region, and each board can only be used with its same-colored mate. The exception to this is that the blue and green boards can be used together.
