Hello Gregory :-)
As I have two MC68000 machines right now (Atari ST Mega1 and Amiga
600) this seems to be simpler task as the first step in porting.. at
least we have standard serial port in those machines and much more
memory to operate on :-)
A port to one of the WDC 65xx parts would also be interesting:

Sure thing! 8-bit machines are smaller and porting may be considerably
harder so this seems good second step after training on 16-bit
machines :-)
Many of the WDC 65xx chips support 16 processing on a 16MB address

These are newer designs, but developed by the original 6800/6502 patent
