Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Settled on the new average-of-length approach to a PLL window sizing, eliminating the old errors-of-phase approach. Since it anchors automatically to the original target clocks per bit, killed the explicit mention of a tolerance.

With lots of logging arising temporarily, fixed bug whereby conversion to a patched track would lead to holding a track with a distinct measure of time, leading to improperly-placed patches.

Eliminated special case that doesn't seek properly and isn't needed. Added TODO.

Fixed: cycles_per_bit_ isn't a function of the rotational multiplier, it's absolute. Also made sure that exactly hitting the end of a bit counts.

Shuffled a little to reduce risk of overflow, ensured writing is a loop, still seem to be writing too quickly for some reason.

Started implementing write sector on the 1770, immediately deciding it would be useful to have a callback for end-of-queued-data-written from disk controller. So had a go at implementing that, naively. More investigation required.

Actually, at least index holes will still be receivable while writing, so this wasn't entirely correct. Probably best to leave it in.

This is almost complete, except that it doesn't act appropriately if some bits are written but not enough to cover the entire writing period.

This is a much better way of dealing with being partway into an incoming event. Subject to eliminating overruns, of course.

Split the status up into flags, assembled into a register upon demand. Attempted to implement some of the differences between the 1770/1772 and 1773/1793. Albeit with a motor fix still in place.
