Some minor tidying, lots more of the caveman stuff as I try to determine what I'm doing wrong.

Fixed framing and first-byte-after-sync signalling. Hacked together as parts of it are, loading now appears to work!

Put in the absolute minimum logic for drive motor emulation. Drive appears to be attempting head steps.

Added overflow-flag setting logic and ensured disk ROM gets through regardless of ROM/disk installation order.

Made attempt to connect sync detect and then apply appropriate windowing, posting bytes to the appropriate place.

Reeled back all appropriate pieces of caveman debugging.

Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more.
(obiter: the 1540 now appears to discern the correct sequence of bits. Framing is off in my test printfs but that's neither here nor there).

Wired up the 1540 as a PLL delegate. Which prima facie means it should start receiving a bit stream. Except that I clearly have something in the timing way off — either my flux transitions are far too short or I need to significantly increase the clock rate on the PLL.

Started turning the 1540 into an actual disk drive.

Completed handing of the disk all the way to the 1540.

Started trying to clean up, including commuting the C1540 source file name to match its class name but mainly by adding documentation.
