1c154131f9 Expands size of storage in Cycles/HalfCycles; adjusts widely to compensate. 2019-10-29 22:36:29 -04:00
Thomas Harte
f668e4a54c Makes an attempt at getting the 5380 past arbitration.
Not entirely successful. Also gets a bit smarter with `final` on ClockingHint::Sources.

Thomas Harte
b9c2c42bc0 Switches drives to using floats for time counting.
Hopefully to eliminate a lot of unnecessary `Time` work; inaccuracies should still be within tolerable range.
2019-07-02 15:43:03 -04:00

7591906777 Numerous IWM fixes: the machine now seems to be trying to measure the tachometer. 2019-06-06 18:32:11 -04:00

ef19a03efc Drives can now deliver activity events. 2018-05-10 21:54:10 -04:00
Thomas Harte
f65c65569a Makes disk head position explicitly something with sub-integral precision.
Also as a drive-by fix, corrects accidental assumption of 10 sectors for all MFMSectorDump descendants.
2018-05-06 23:17:36 -04:00

7061537ff5 Makes joined-up attempt to run data through the Disk II. 2018-04-24 19:44:45 -07:00

Thomas Harte
97a2be71e3 Introduces flush_tracks to Drive, while switching its interface to using Track::Address and adjusting associated integer types. 2017-10-06 21:45:12 -04:00

698e4fe550 Tidies the Disk file hierarchy. 2017-09-22 22:39:23 -04:00
Thomas Harte
da082673d7 Drives now have a finite number of heads.
The Amstrad volunteers itself to be single sided. Everything else stays as it was.
2017-09-15 21:18:36 -04:00

82b13e98f2 Implements the real hardware ready test for Drives — motor on plus two index holes. 2017-09-11 22:27:50 -04:00
Thomas Harte
8882aa496f Corrected wiring to get advance signals through to Drive event delegates. 2017-09-10 20:51:05 -04:00

0622187ddf Strips Controller of all capabilities now housed on the Drive. 2017-09-10 19:23:23 -04:00
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 `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.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

ff6e65cca9 Introduces necessary storage and interface for writing. 2017-09-10 16:23:31 -04:00

90c7056d12 Started devolving timed event loop logic down to the drives, moving them closer to modelling real life. 2017-09-10 14:43:20 -04:00
Thomas Harte
49285e9caa Attempted to implement Sleeper in Drive and therefore in DiskController. Also corrected a couple of nonconformant file names. 2017-08-20 11:54:54 -04:00
Thomas Harte
5344e3098b Minor: made has_disk something that is decided on insertion/deletion. 2017-08-20 10:55:08 -04:00
Thomas Harte
eec42aa7ae 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. 2017-08-08 21:15:56 -04:00
Thomas Harte
0490a47058 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. 2016-12-26 14:24:33 -05:00
Thomas Harte
f601d796f5 Added documentation. 2016-12-24 22:37:20 -05:00

572d5587d9 Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register. 2016-09-25 21:24:16 -04:00
