	depending on HOW different the 68hc11 is from the 6809 you
MIGHT be able to patch a copy of Os9 for the 6809 to run on the
68hc11.  It certainly could take advantage of the extended memory
versions.  It's a FAST OS (for being 8bit) leaves cpm in the dust 
and is fairly unix like.

	Though not completely I can't find my old OS disks (BUMMER)
but anyhow if you can get a copy of this and read the binary image
and make mods this certainly would be a way to go since Os9 only needs
4k of ram and can boot from rom (including load modules from rom).
kernal needs 1k so ... it also supports all the nice features of Unix

	Did I mention it was FAST? :) if you can get BasicO9 running
under a hacked kernal then you will be really in good shape (it's very
fast for a basic and is more pascal like than basic like)

	Anyhow I believe MicroWare doesn't support Os9 for the 6809 
anymore.  So IF you find a copy of Os9 and can hack it ... not sure.
