Not really a general purpose computer more like the

The C64/Coco/Apple was the quick and simple computer - 8k rom - 64k D-ram
and a graphics chip and CPU. It was the cost cutting that got ya like none of
the common 8 bit computers had a serial port.
Huh? The CoCo had a standard RS-232 port, with the exception of the control
lines. It ran standard RS-232 voltages & with software handshaking worked
just fine, albeit slowly as it was bit-banged instead of UART driven (which
on the CoCo1 & 2 I can sympathize with... but to not include a UART on the
CoCo3 as they'd become *very* cheap by then, that was just plain
*stoopid*... :-( )
Mind you with fast ram now days and programable logic a
nice OS-9
machine could be built. Finding a fast 6809 chip is the problem.
Boy I wish OS-9 was open source.
Huh? 40Mhz ain't fast enough for you for a 6809??? :-)

Granted, I have *no* idea how much these cost or anything... :-/
*I* wish OS-9/68K was available for my Palm... It'd knock PalmOS for a loop!
