I read what he wrote differently >> If only there had been a popular 6809-based computer with better hardware than the CoCo. > That wasn't really the issue, the C64 wasn't much better the 6809 was a really nice "ultimate" evolution of the 8-bit CPU. The C-64 was just another primitive 6502. So I think GP meant "I wish there was a 6809 I could get that wasn't the CoCo, because I want a 6809!" rather than meaning that the hardware doomed the CoCo or something.

In a way it did. Tandy offloaded every possible function onto the processor to lower part count and hence cost, resulting in the infamous bit banger serial port and the equally infamous high resolution mouse adapter, which made the CPU time the discharge of a capacitor to figure out where the mouse pointer was, so you learned quickly to keep the mouse at the top left, minimizing that time, unless absolutely necessary. DMA for disk I/O? Only with third party hardware.
