That being said, there were more computers with a 6502 (cheaper) and
more people programming it.
I think 6502 programmers and computers evolved to the Zilog Z-80 with
many new systems using it.
The brilliant 6809 just didn't get the same popularity even though it
was so much better.
Smells of the VHS and Betamax scenario doesn't it? :)
