The DD-400 package is the combination of a 3.5" 720kB disk drive and an interface cartridge. It seems to be the same as the Canon VF-100 and Yamaha FD-05.

The interface includes a ROM with version 1 of the Disk BASIC instructions.

Note: the DD-300 indication on the advertisement actually refers to another product released by Fenner, before the DD-400.
