Actually, OS-9 only hooks into the SWI2 vector.  Given that, I  
believe it might be possible to do a port of CUBIX so that it  
actually ran under NitrOS-9 Level 2 as a process.  The I/O routines  
that need to be written could actually be written to invoke OS-9 I 
$Read/I$Write calls, and since each process gets its own 64K space on  
a CoCo 3, this isn't as far fetched as it may sound.

I tend to agree with James; if one wanted to port CUBIX straight to  
the CoCo, it would be easier on a CoCo 1/2 than on a CoCo 3.
