Input sort of works now! Except that key repeat is way out of control.

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.

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.

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.
