Fixes keyboard data return.
...
Input sort of works now! Except that key repeat is way out of control.

Just a guess. But likely?

eccf5ca043
Makes first effort to wire up the ADB vertical blank input.
...
However: looking at the disassembly, I'm not sure it really is wired to INTR. So work to do.

6e53b4c507
Corrects centralised ADB decoder.
...
I still think it's appropriate to do this in only a single place, given that using it is optional.

Thomas Harte
52c38e72f6
Starts seeking to automate register 3 handling.
...
Immediate pitfall: byte capture on the bus side isn't working correctly.

Thomas Harte
a51d143c35
Corrects reactive-device transmission logic.
...
Albeit that I'm still not properly responding to register 3 stuff, so the ADB bus needn't believe anything is out there. Also, without VSYNC being piped to the microcontroller it may well just not be polling anyway.

Adds a helper for decoding ADB commands.
...
Still very noticeably to do: any sort of standard part for devices to respond to the bus.

Thomas Harte
46bd20b5e0
Attempts to simplify ADB bit parsing.
...
On-line output still looks reasonable, albeit that the microcontroller suddenly seems to be interested in devices F and 3 rather than 2 and 3.

This appears to be sufficient for the Electron to _read_ SCSI.
...
So that's step one.

Rips out my high-level ADB microcontroller protocol implementation.

If I'm going to maintain the max_address approach, & is 'correct'.
...
% +1 would be 'more correct', but I think this approach is probably misguided.
