Forth, CP/M68 could be compiled for it. I'm sure TinyBasic can be done 
from Dave Dunfields TB in C.  the nice part is anyone with a PDP11, LSI11
or sim (including Ersatz-11) can build an image and test it.

It a micro much like 8085 so yes it can be done.  But a small SBC with 32kw ram,
2kw rom and some serial IO is a tiny thing.

That's a bit harder but far from impossible.  considering DEC used them in
Falcon boards, and the the qbus slave (kxt21?), Vt240/241 series, and the 
storage hub (something mumble50).
