The HBD-100 is a single sided 360kB 3.5" floppy disk drive, conceived by Sony in 1984 for the HB-701 computer, allowing to transform it into a HB-701FD computer.

The instructions for the montage are inside the HB-701 machine. The integrated interface includes a ROM with version 1 of the Disk BASIC instructions.

A floppy disk with a sprite animation utility was also probably provided.
