685a80f95b Ensures the Electron Plus 3 properly announces drives to an activity observer.
Does away with lazy allocation as not all that helpful, and liable to cause complexity.

51da21b844 Formally introduces keyboard-as-joystick for the Mac, and fixes discovered joystick issues.
Specifically:
* digital to analogue conversion not returning to centre;
* Apple II axes being the wrong way around; and
* Apple II buttons using improper selection logic.

f1b430338e Makes the Apple II a joystick machine.
Albeit that the values supplied to its joysticks do not currently make it into the emulated state.

d84b8700a3 Switches the Apple II to one byte per pixel.
Just trying to get it right for now; optimisation to come.

8dd7c6ef23 Eliminates 'reversed_c' as I no longer believe low-resolution colour numbers are reversed.
Also gets explicit about phase.

928aab13dc Introduces more granular clocking announcements to the Disk II.
As well as making it accept the clock rate it'll actually receive, to supply to the drives, so that they spin at the proper speed.

7b7beb13a3 Eliminates the fiction of setting and getting registers.
The Disk II seems lower level than that; it will read the data bus whenever it likes, it is the programmer's responsibility to keep up with that. It also reserves the right not to load the bus regardless of whether it receives a read or write access.
