VCC has my emulator version of RGBDOS included within the emulator. (You 
can find the copyright message is you scan the Vcc.exe file.) In fact if 
the .vhd image on the site has not changed, it already has a NitrOS-9 
boot drive included as well as a version of NitrOS-9 itself. It also 
contains some of my utility programs so you really don't need to go to 
my web site. I think the boot is on drive 253 so all you need do is enter:
DOS253
You should find some of my utilities on drive 254.

The only problem with the .vhd image at the VCC site is that the 
NitrOS-9 boot drive is not labeled. One of the features of RGBDOS is 
placing a string in a disk directory so that it is shown by the DIR 
command. The syntax is:
RENAME DRIVE drive number, "string to display"
So you might want:
RENAME DRIVE253,"NitrOS-9 hard drive boot"

If you want support for RGBDOS and how it boots OS-9, you need to 
contact me not the VCC author. The Cloud-9 HDBDOS is modeled after the 
original Ken-Ton RGBDOS so if anyone wants to "try out" a Cloud-9 
system, RGBDOS on a emulator is the way to go.
