-The external floppy disk drive connecter is labelled "​EXTERNAL FDD" on the back of the X68000. This is a pretty common connector known as the "D-SUB 37 pin female connector"​. In order to connect an external device to this port a D-SUB 37 pin male connector is necessary. One should be able to purchase a D-SUB 37 pin male connector at many online retail stores. You will also need to purchase the matching enclosure shell for the connector. Lastly, you will require a way to connect this to the FDX68. ​ A standard floppy disk drive cable (ribbon or round) will work well.+The external floppy disk drive connecter is labelled "​EXTERNAL FDD" on the back of the X68000.

-When making your own cable to convert from D-SUB 37 to the 34-pin connector found on the FDX68, the following conversion table should be referenced. The pin assignment for creating ​the conversion cable is as follows. After soldering the pins, one should confirm they cable is soldered correctly using a voltmeter.+When making your own cable to convert from DB37 to the 34-pin connector found on the FDX68, the following conversion table and FDX68 pinout ​should be referenced; match the description of the pins and solder accordingly. After soldering the pins, one should confirm they cable is soldered correctly using a voltmeter.
  
-... to do ...+NOTE: The DB37 connector should have numbers on them ​Follow those numbers ​Don'​t get confused by the picture below as the pin numbers are different depending if you look at the front or the back of the connector.
