[Coco] Multi-Processor 6809 Computer System

[Fedor Steeman]

I have always loved Sock Master's suggestion for a CoCo4:

If we had plenty of 6309s lying around at a decent price, how doable would
achieving a board like this be? Or would it never work unless you had a
production company behind it?

Cheers,
Fedor
