64MB on a 6809?

Thinking about 68K netbsd on the old 4MB Macs about 18 years back. Early
versions of Linux or BSDs could be ported, beginning about 2MB, and made
more functional even up to 128MB. Puppy Linux may still be viable.

Fuzzix?

32 or more processes? Yeah, even the old Linuxen and BSDs tended to have
that many processes in the run list.

And there is a great advantage to having them in memory, especially on
speed starved CPUs.

One thing that would make a lot of sense,  even at 512K, would be to add
true DMA -- general DMA, not just video. Of course, that means some kind of
additional wiring to daughter cards for persistant store interface and
serial device (Network adapter, etc.) interface.
