Worked on the all-around framework for decoding sectors back from tracks when closing down a file. Hit the wall that the parser is more observant of CRCs than the WD. No, really. So I guess I have to stop avoiding that whole issue.

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.

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.

Added enough stuff that SSDs attached to a 1770 will now reach the entry point for writing.

Let's try just declining to pump the PLL while in write mode. Added documentation to explain.

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.

Withdrew now-unused and never-implemented API from TimedEventLoop, and the redundant track time count from DiskController.

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

Started stepping slowly towards allowing writing on the disk controller, taking the opportunity to introduce self-simplifying behaviour to Storage::Time.

This'll do as a write interface, won't it?

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.

Renamed class, intending to turn a Disk::Drive into literally just that, and have a thing with a PLL that consumes events be a Controller.
