NitrOS-9 works on the Keil emulator. I just tested 6309 NitrOS-9 on with 
the 6309 version of Keil. There is one problem that must be satisfied 
for this to work.

NitrOS-9 is distributed on a JVC type disk image. While this works with 
the Keil emulator it is not the native format. Best results or maybe the 
only way to run NitrOS-9 is from a .dmk image. For some, this could be a 
Catch-22 situation.

I use several emulators so have available wimgtool from MESS. I used 
this program to create an 80 track double sided .dmk OS-9 disk image. I 
mounted this image and a NitrOS-9 distribution disk (renamed to .os9) in 
MESS and booted NitrOS-9. Just to be sure I then formatted the blank 
.dmk image and then backed up the JVC .os9 disk to the .dmk disk.

The new .dmk version of the NitrOS-9 distribution disk booted and ran 
normally using the Keil emulator.
