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.

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.

Rips out my high-level ADB microcontroller protocol implementation.
Adds just enough that the main computer validates the ADB controller as present and talking.

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.

Resulting in an unexpected interest in R15. Bugs to find, I guess.

Ensures ADB microcontroller is clocked.
And runs at the 'correct' speed (i.e. modulo my instruction-by-instruction implementation).

That's better than failing at the first.
