Hard Disk Performance under Disk BASIC

Originally known as RGB-DOS, our new and improved version is fully compatible with Disk Extended Color BASIC. HDB-DOS supports Cloud-9's SuperIDE Interface and TC^3 SCSI Controller, as well as the Ken-Ton and Disto SCSI controllers and the Glenside IDE Interface!

As a convenience to the Color Computer community, Cloud-9 is offering NitrOS-9 on two 5.25" floppy diskettes for small copying and materials fee.
