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.

Switched to a full-on linear regression. Which causes the current tests to pass.

Started sketching out the basic form here, albeit that it doesn't yet do _the only thing it advertises itself as useful for_.

Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.

Actually, I think this is the correct conversion from received speed to clock rate. It'll become obvious if it's not when I get back to working on the 1541 itself.

Put sufficiently much of PCMTrack into place to get to a stored list of segments, having determined a common clock rate between them and therefore a complete track length.

Working towards HQ UEF support: fixed bug whereby writing to tape output would reset input pulse stepper; added support for chunk 0116 and approximate support for 0113.

With silence and high tone implemented, this may well hit a large proportion of existing files.
