[Coco] CUBIX on the CoCo?

[Boisy G. Pitre]

Dave,

I'm not familiar with CUBIX, but i like the idea (and the challenge)  
of porting a new OS to the CoCo!  If I had the time, I would consider  
it, but I am overcommitted as it is with NitrOS-9 and things outside  
of the CoCo, like school.  I think it would make a very interesting  
semester project for a student, though.

One thing I am curious about: what tools would be used to assemble  
the OS source and the needed block and term I/O routines?  Don't you  
have a set of Windows based tools for assembling 6809 code?  Check  
out ToolShed (www.nitros9.org/toolshed).  We have a 6809/6309  
assembler as part of the package.  It may be of interest to you or  
whomever may be considering taking up the CUBIX port.
