 2017-09-10 22:56:05 -04:00
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.

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 `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.

6075064400 Adds the ability to query a TimedEventLoop for its input clock rate. 2017-09-10 17:31:43 -04:00

ff6e65cca9 Introduces necessary storage and interface for writing. 2017-09-10 16:23:31 -04:00
Thomas Harte
90d2347c90 Extended to permit subclasses that are interested to get sub-run_for information about event times. 2017-09-10 14:44:38 -04:00
Thomas Harte
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
a3e2d142e3 Extends UEF support to include chunk 0005, the target platform description, which is exposed via TargetPlatform::TypeDistinguisher. 2017-08-27 15:43:09 -04:00
Thomas Harte
4465098157 Since it has descendants, gives Storage::Cartridge a virtual destructor. 2017-08-27 15:19:30 -04:00
Thomas Harte
56dd677e9c Creates a virtual interface that can be adopted by classes that are able to provide some insight as to target machine. 2017-08-27 15:19:03 -04:00

9aa150c338 Abstracts the target platform type out from the static analyser's ownership. 2017-08-27 15:02:13 -04:00
Thomas Harte
c6e6c3fcfb Resolves all current analyser warnings. 2017-08-24 22:18:44 -04:00

0cbc1753b9 Quick fixes: the binary tape player now considers talk to the sleep observer only if motor control changes. The Amstrad CPC no longer attempts to use the component argument to identify the caller, since this will often be that of the superclass and not that of the derived class known to the CPC. 2017-08-20 13:18:46 -04:00

8fdc5012e4 Updated TapePlayer and BinaryTapePlayer to be sleepers. 2017-08-20 12:18:36 -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

5344e3098b Minor: made has_disk something that is decided on insertion/deletion. 2017-08-20 10:55:08 -04:00

ef07c33741 Merge branch 'Plus10' into MFMParserDensity 2017-08-18 15:48:20 -04:00

e559a65ede Ideally I would be able to kill this multiplier, as it could easily be derived at runtime. But, for now, just turned it up so that the analysis-oriented parser is better at parsing different bit rates. 2017-08-18 15:47:46 -04:00
Thomas Harte
af61a7fa28 Two quick fixes: correctly set segment size, and flip bytes to match HFE's bit ordering to PCMTrack's. 2017-08-17 22:28:00 -04:00
Thomas Harte
c8c1792c3f Made a first attempt at HFE support. 2017-08-17 22:20:02 -04:00
Thomas Harte
e6683e7f2d Added the base skeletal stuff of HFE support. 2017-08-17 21:48:48 -04:00
Thomas Harte
0c1714b695 Relaxed a little to allow +10% in track length. 2017-08-17 21:36:14 -04:00
Thomas Harte
2c2dd8073c Modified to return nullptr if asked for an extended disk image track that doesn't exist. 2017-08-17 15:32:24 -04:00
Thomas Harte
4f8b89772e Improved logic for detecting when all sense has been derived from a track to spot any repeated track, not necessarily the first one. That avoids sectors that run over the index hold and obscure the first throwing things. 2017-08-17 15:31:53 -04:00
