Is this just a "wishing post" or is this truly a call for features that 
someone can implement?

I know this is a CoCo list, but there was a long ago effort to port OS/9 
to the Commodore SuperPET, and I would love to see this codebase run on 
that environment. It's not a feature per se, but would be a neat target.
