DIP SWITCH SETIING The MZ-1R12 (S-RAM board) can be used with the MZ-700 Eight-bit port addresses are output from the ZSO·CPU. either for a boot loader function or as an external memory. Because three consecutive port addresses are used with this card, the six high-order bits of the eight-bit address signal are selected by the switch in order to set the port address. The MZ-1U03 is needed to connect this card to the MZ-700. . --- -- --- Z.FUNCTI6NS - .
