Amstrad Compatibility

The AMSTRAD model FD-1 may be added to the +3 system as an additional disk drive. To connect the FD-1 to the +3, you will require the AMSOFT DL-2 disk interconnecting lead. Connect the end of the lead which is fitted with the larger edge-connector plug, into the socket marked DISK B: at the back of the +3. Connect the other end of the lead which is fitted with a smaller plug, into the socket at the back of the FD-1 disk drive.
