( Inside the MZ-1E14 )
This interface connects an MZ-700 series personal computer and the MZ-1F11 disk drive.
The interface reads the system software ( BASIC 5Z-008 etc. ) with built in IPL ROM. ( This takes about 8 seconds, not including AUTO RUN. )

Three types of files can be cataloged on a MZ disc:

1. BASIC text file ( program )
2. Sequential data
3. Machine language ( system software, etc. )

Up to 32 files can be cataloged on one side of a disc ( the number of files equals to the number of programs or group data entries ). If only one program file is cataloged per side, the maximum storage capacity is 64 Kbytes. As the number of files increases, the storage capacity decreases. This is because a gap is required between files. Sequential data files are blocked in units of 1 Kbytes; the maximum storage capacity of a disc side is about 40Kbytes.

To connect the MZ disc drive to an MZ-700 series computer, perform the following.

1. Turn off the power of the computer and unplug the AC cord. Remove the two screws holding the data recorder from the left rear side of the computer. Lift the data recorder out of its mounting. ( See picture below )
2. Remove the connector ( CN1 ) between the data recorder and the MZ-700 series computer.
   
   

When the data recorder is to be used, connect it to the MZ-1F11 connector ( click here for details ).

1. Remove the bottom plate of the MZ-1F11 as follows:
1. Unscrew the screws holding the bottom plate at the rear side.
2. Remove the bottom plate in the direction indicated by the arrow.
   
   





2. Connect CN2 ( from the bottom of MZ-1F11 ) to the connector of the computer main unit that was originally connected to the data recorder. ( See picture below )
3. Mount the MZ-1F11 where the data recorder was originally, using the screws that held the data recorder in place.

   
   
   

1. Remove the cover for the external output terminal ( I/O bus ) at the back of the computer main unit by unscrewing the two screws for mounting the MZ-1F11.
2. Plug CN5 of the MZ-1E14 into the external output terminal at the back of the computer and secure it with the two screws you just removed.
3. Insert CN3 at the rear of the MZ-1F11 into CN4 of the MZ-1E14 and secure the connection using the screws originally securing CN3.

This completes connection of the MZ-1F11, the MZ-1E14 and the computer.

The remover data recorder can be connected as an external unit to the computer as follows:

1. Remove the cover for CN6 from the rear of the MZ-1F11, then insert CN1 from the bottom of the data recorder into CN6.
2. Use the extension cable to be connected to CN1 and CN6, if you prefer more distance between the data recorder and the computer main unit.

This step completes the procedure. Switch on the power, and check operation.
