[Coco] Multi-Processor 6809 Computer System

[Luis Antoniosi (CoCoDemus)]

the 6309 is more efficient when in native mode than 6809. Would be a good
start doing a FPGA socketed chip that would be efficient as possible
running on same 1.78 mhz  ? Just remove the 6809 and plug this one. This
would boost a lot the speed without needing to mod the machine and make
complicated overclocks.

Not a computer engineer expert but IFAIK only scalar architectures can
achieve 1 cycle per instruction by pre-fetching and pipelining instructions
and predicting branches. But on a coco machine what would be smaller cycle
count ? 4 cycles ?
