6. 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.
