[Coco] DECB and BACKUP

[Bill Pierce]

Actually Robert, my starter kit page only has the Becker versions of hdbdos. One of these days I'll add the Real Coco starter kits.

The place to get the HDBDOS roms (all forms) is:

That is a failure of the Tandy Disk Basic. If you are able
to replace your Disk 
ROM with RGBDOS or HDBDOS, then the Backup command will
not erase programs in 
memory. HDBDOS is available in a LOADM format for the
Coco3 so you won't need to 
burn an EPROM for that unit.

I can supply RGBDOS
for a Coco3. HDBDOS with Drivewire access can be had
from
https://sites.google.com/site/dabarnstudio/the-color-computer-drivewire4-hdbdos-nitros9-starter-kit

The
easiest way to get many different versions of HDBDOS is by compiling 
Toolshed.
That however is not for beginners.
