[Coco] Help with dumping various EPROMS

[Ron]

Hi Bill,

I am an original owner of RGBDOS and can try to dump it, if that sort of 
thing is allowed, for anyone that may need it.

Thanks!

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.
