I assume that the PWM functionality is built into the microcontroller 
for the ability to control things like stepper motors

Sounds cool but I wonder how many CoCo enthusiasts would actually do this.

Is there an option in the controller to vary the amplitude of the PWM or 
better still, a DAC to dump data from the RAM to the sound output for 
enhanced game sounds?

I also assume that any PWM sound will not be mixed with the CoCo's 6-bit 
sound.

(So many questions.)    :)
