[Coco] Help with dumping various EPROMS

[Bill Pierce]

Actually, all the ADOS roms and the CDOS roms should already be available (in binary form) in one of the various archives. RGBDOS is available, but it's the version set up for the emulators to use VHDs. I don't think I've seen the original RGBDOS roms anywhere, though I know several people here on the list have RGBDOS systems and could possibly dump one.

On the other hand, HDBDOS has all but replaced all of those in versitality and ease of use. Versions are supported for almost all types of drives as well as emulators and DriveWire. There are currently experiments ongoing in making HDBDOS a 16k rom and adding more features.

Ya gotta love the Coco Community... :-)

Bill, I'm pretty sure those vectors are copied by some magic or other
from
$BFF0-BFFF in the Color Basic ROM, and need not be burned into the
EPROM.
