Switches drives to using floats for time counting.
...
Hopefully to eliminate a lot of unnecessary `Time` work; inaccuracies should still be within tolerable range.

Numerous IWM fixes: the machine now seems to be trying to measure the tachometer.

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.

Thomas Harte
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 `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.
2017-09-10 17:33:01 -04:00

Introduces necessary storage and interface for writing.

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
7d1023ea98
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.
