Makes a first sweep at converting the storage underlying PCMSegment to vector<bool>.
...
This is to remove another pain point, in preparation for the work immediately forthcoming but also work as-yet unknown.

Introduces flush_tracks to Drive, while switching its interface to using Track::Address and adjusting associated integer types.

Drives now have a finite number of heads.

The Amstrad volunteers itself to be single sided. Everything else stays as it was.

The Drive now no longer produces input when in writing mode — other than announcing the index hole.

Thomas Harte
82b13e98f2
Implements the real hardware ready test for Drives — motor on plus two index holes.

Thomas Harte
6d6cac429d
Fixes extra time accumulation during track running.
...
Introduces a bunch of further asserts, which aided me in determining the fix, i.e. that Drives being responsible for their own setup_track could double-pump the event loop.

a4e275e1fc
Provides an implementation of Drive's new interface.
...
Mostly lifted from DiskController. `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.

Started devolving timed event loop logic down to the drives, moving them closer to modelling real life.

Attempted to implement Sleeper in Drive and therefore in DiskController. Also corrected a couple of nonconformant file names.

Entrusted further status to drives; also adjusted them to report read only if diskless, which I now believe to be correct.
2017-08-13 11:50:49 -04:00
Thomas Harte

Added a 'ready' getter to Drive, formally to let the drive take ownership of that test.

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.

Extended Storage::Disk::Disk to permit write-back of modified tracks, exposed some interface via Storage::Disk::Drive.
