> CoCo was an extremely nice machine with a lot of software tricks to emulate hardware that wasn't there. 6 bits a/d & d/a with a bunch of resistors and a single comparator, audio in/out and doubling as a cassette interface. Very elegant design.

It was a wonderful set of hacks. And, since almost everything was software, you had to understand what was going on rather than just magically offload it to a chip that just handles it.

The whole idea of making a dinosaur "roar" drove me down the path of sound effects, audio synthesis, ADC/DAC conversion, Fourier analysis, etc.

And the CoCo had William Barden writing books and articles that were way ahead of anything that you could have rightfully expected.
