The Sony HB-701FD is the first Hit bit Computer equiped with a built-in floppy disk drive (see HBD-100). This machine was aimed at the Japanese market and available in black on front and pale gray.

The only difference between the HB-701FD and the HB-701 is the drive, which is build in the HB-701FD. Front and back of both machines are exactly the same, with only a little difference on the left front, corresponding to the location of the drive.

The machine has a separate keyboard without numeric keypad. It's a QWERTY Japanese keyboard with ANSI layout for kanas characters. The provided floppy disk contains a sprite animation utility.
