By using a PLD chip, we could make the switching of different games as easy as using a dipswitch. This will allow anyone that is not comfortable with electronics to be able to change to any one of over 90 preprogrammed different games plus free play. The PLD contains complex logic that eliminates the need for jumpers and reduces the overall component count. Better yet, no more changing of jumpers or unsoldering wires to change a MPU board from one game to another. Plug and Play at its best.
