Threw a sector cache into my MFM parser, in an attempt to cut down analysis costs. Also made it aware of multiple heads.

Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.

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.

This'll do for getting the ADF into the machine.

Made a first attempt at Acorn ADFS support plus the start of a suitable analyser.

Added shift-break as a better way to boot suitable disks. Continued attempting to clean the 1770.

Tweaked disk side density, added call-outs to a WD1770 if the Electron had one (albeit without run_for_cycles yet as I need to figure out the clock rate), added a shell of the basic functions of the WD1770. No implementation yet.

Added CRC checking to DFS comprehension; fixed a bunch of places where I'd used Objective-C's #import rather than #include.

Introduced a full container for disk catalogues, so as also to capture non-file information, and 'completed' (i.e. albeit that CRC checking is still absent) DFS catalogue decoding.

This is exactly as far as I'm going to get with DFS parsing today, I think.

There's no cache and no CRC checking yet, but this is probably a rough outline of an FM parser.

Added necessary wiring to get as far as asking an arm of the analyser to check out an Acorn disk image.
