[Coco] Computer Assisted translation of programs form 6502 to 6809

[Dave Philipsen]

Nope, I specifically wanted the cross assemblers mostly for the ability 
to make modifications for the assembler to accommodate some new 
instructions that were present in the 65C02 which I and some others were 
working with at the time.  They were instructions that were not part of 
the original 6502 instruction set.  My hope at one point was to also add 
instructions to the 6809 assembler to effectively create a 6309 native 
mode assembler but it wasn't a priority at the time. I only ever worked 
on one 6809 project that was a commercial project (maybe two if you 
count SuperComm as a commercial project) and neither used a 6309 at that 
time. In fact, some may disagree with me on this but even now I do not 
perceive that much of an improvement of the 6309 over the 6809 with the 
exception of the shortening of some instruction cycle times that gives 
the 6309 the real edge over the 6809 in the neighborhood of maybe 10% on 
average.
