Adds a receiver for drive-motor control bytes.

All proper inputs are now provided to the audio generator.

Hopefully. The next job is to generate audio. If that sounds correct, then the disk motor speed question can be tackled.

Adds enough of a concept of Mac video to get a properly initialised display.
...
