The Dragon was actually a clone of the CoCo -- I don't think it was licensed or endorsed by Tandy, but someone else could probably tell you more if you're curious.

I still claim that the 6809 is the most powerful 8-bit processor ever made. With 16-bit accumulator, index registers, stack pointer and branch instructions it fixes all of the 6502's shortcomings. And even cooler, there's a version of it with multiprocessor support. And it's really easy to port 6502 source code since the instruction sets are fairly similar.
