ede2696a77 Edges further towards implementing the IIe video subsystem.
All video-specific switches are in place, and mostly honoured, and a IIe machine configuration is advertised at least.

59b9e39022 Starts the process of supporting the Apple IIe graphics modes.
Albeit that I'm not yet even up on the proper soft switches.

3862fdb44c Simplifies initialisation procedure for all machines.
With the side effect of allowing every machine to try to load only the ROMs that it needs.

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.

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.
