Since nobody had a 6809 assembler in Forth, I wrote one.  If anyone
would like a copy, mail me.

Is anyone else running Forth on the 6809?  It's a good combination.
The public domain fig-Forth for the 6809 is not so great; for example,
its "*" (16x16->16 multiply) does shift 'n add to get a 32 bit product,
then drops the high word.  Close to 1000 cycles.  Using the 6809's MUL
instruction, you can cut this down considerably (83 cycles for the
unsigned version).
