[Coco] NitrOS9 ROM

[Hugo Dufort]

You could also write an OS-9 ROM bootloader. That is, a tiny routine 
that boots OS-9 from disk without ever loading the DECB/Microsoft stuff 
into memory.
I guess you could do that using the tiniest ROM available!

Or maybe I'm wrong and it's not possible?!

My original search this morning only turned up the FAQ page and I was unable to find anything else about the kit through the normal Cloud9 site, which led me to believe I stumbled on a dead page and the kit wasn't actually valid anymore... thus my initial post to the group.
