[Coco] Dual Processors?

Does this mean that dual processors (6809/6309) would be a possibility?  I'm
sure this has been considered before?  Can os9 be modified to handle dual
processors?

With SDRAM you will need a SDRAM controller. 

There is a SDRAM dual port and single port controller that can be integrated

into a CPU core. I t is configured so that it can be accessed like Static
ram and 
will handle 8 MB SDRAMS. 

All the modern x86 processors now have the SDRAM controller as part of the 
CPU core. DOing that for a 6809 core would open up greater possibilities.
