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).

Increased logging; discovered I was packing events together too closely. Now getting some zeros.

Attempted to give the PLL a litte extra leeway, and fixed PCMTrack length test.

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.

Filled in a calculation of clocks per bit that'll do.

Took some small steps towards having a disk drive that at least can select a track and pump relevant events into a PLL.

Made an attempt to eliminate creeping tape processing accuracy misses, which implied factoring out the GCM and LCD functions, which I then felt didn't really amount to signal processing.

Added just enough to get back to a working build.

Started fleshing this out a bit. Hopefully.

Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower.
Started sketching out a DiskDrive class.
