Fixes mouse input when a button is pressed; attempts keyboard input.
I think the VIA is somehow sending spurious commands.

Possibly mights the tiniest bit of headway with 'the IWM'.
I'm now pretty sure that my 3.5" drive, which for now is implemented in the IWM (yuck) is just responding to queries incorrectly.

Adds a receiver for drive-motor control bytes.
My new belief is that I'm either reading the buffer from the wrong place, or the 68000 isn't filling it for some reason.

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.

With some time additions to the 6522, starts wiring in Macintosh audio.
The audio buffer is also the disk motor buffer, so this is preparatory to further disk work.

Takes a first crack at the keyboard's serial protocol.
Albeit that without a working shift register in the VIA, this shouldn't really work yet.
