Flex was modeled after CP/M, I believe, and originally ran on the 6800, 
ported later to the 6809.  Uniflex, as has been stated, was supposed to 
add multi-tasking and be more UNIX-like.  Flex ran on the CoCo 1/2, but 
those versions broke on the CoCo 3, and I'm not sure if it was ever 
patched or updated to do so.  I don't think there was a Uniflex that 
worked on the CoCo.  However, I believe the source code for most of 
Uniflex was uncovered and can be found online if you look for it.  
Porting that to the CoCo 3 would be a project for somebody.
