Although it seems possible, is it within the limitations of a small group
of hackers to reproduce the logic of older chips, such as the MC6809E,
when current supplies cease?

I think this has been discussed on the Coco mail lists.

Yes. In fact there are a few 6809 implementations in FPGA that can be
obtained.

************
There is already several VHDL cores for the MC6809. Of which one is
part of SoC and is under GPL. It could be stripped out and used as
stand alone processor.

try www.opencores.org look for sytem09 in the projects.
