Thomas Harte	63ff5165a4	After a quick bit of reading, discovered the virtual copy constructor pattern really is only a convention in C++, and conformed to it. Which hopefully gives copyable tracks.	2016-12-30 17:25:39 -05:00
Thomas Harte	71dbd78cf2	If asynchronous background processing is to occur on tracks then, given that they inherently have state, they'll need to be copyable, and ideally 'cheaply' (though it's not too great a priority). So started implementing appropriate copy constructors. Also introduced an extra level of indirection to PCMSegmentEventSource so that it can copy itself without copying the underlying PCMSegment, which is 95% of the heft of a track in all currently-implemented cases.	2016-12-30 14:23:26 -05:00
Thomas Harte	e081f224b6	Implemented a very basic PCMTrack test, nevertheless revealing an oversight in PCMSegmentEventSource related to improperly counting to the index hole if the final bit is set. Took that as a message that I should comment and document the event source.	2016-12-18 22:53:24 -05:00
Thomas Harte	a6354ebb01	Reimplemented PCMTrack to use PCMSegmentEventSource, eliminating code duplication.	2016-12-18 21:37:05 -05:00
Thomas Harte	f1a08b7ab5	Opted to pass times by reference and added enough to PCMPatchedTrack that it could start being used by the disk controller, albeit that it doesn't work.	2016-12-17 16:26:45 -05:00
Thomas Harte	0dc2aa6454	Commuted all of 'Storage' other than 'Tape' to postfix underscores.	2016-12-03 11:59:28 -05:00
Thomas Harte	5409c8ec54	Switched PCMSegments to std::vector; ensured generated [M]FM tracks are correctly sized, thereby making sure the individual flux windows will be correctly sized.	2016-09-18 18:56:35 -04:00
Thomas Harte	56c0d70c1f	Gave disks their own namespace.	2016-08-27 17:15:09 -04:00
Thomas Harte	3e90b85ff8	Made an attempt to insert proper conversions to/from rotational speed. The Time class is now really turning into a full-on quotient. Might need refactoring.	2016-08-04 21:36:39 -04:00
Thomas Harte	e57ab1025d	Fixed location calculation, up to a point.	2016-08-03 22:33:00 -04:00
Thomas Harte	30f8b6baa4	Made an attempt to add the necessary extension to Track, with a concrete implementation in PCMTrack, to support time-based seeking, the intended mechanism for not magically spinning the disk back to the index hole upon every head step.	2016-08-03 06:59:45 -04:00
Thomas Harte	a00f9adba3	Made a first attempt at D64 support. Made an error somewhere but this should be 90% of it.	2016-08-01 08:41:16 -04:00
Thomas Harte	198fbbedc7	Reeled back all appropriate pieces of caveman debugging.	2016-07-31 13:42:34 -04:00
Thomas Harte	2332f72875	Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more. ... (obiter: the 1540 now appears to discern the correct sequence of bits. Framing is off in my test printfs but that's neither here nor there).	2016-07-31 13:32:30 -04:00
Thomas Harte	6ee784a893	Increased logging; discovered I was packing events together too closely. Now getting some zeros.	2016-07-30 04:30:55 -04:00
Thomas Harte	fead524eb5	Attempted to give the PLL a litte extra leeway, and fixed PCMTrack length test.	2016-07-29 18:52:50 -04:00
Thomas Harte	e55db0cfe8	Made an attempt to eliminate creeping tape processing accuracy misses, which implied factoring out the GCM and LCD functions, which I then felt didn't really amount to signal processing.	2016-07-29 05:19:01 -04:00
Thomas Harte	0aa90b943b	Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower. ... Started sketching out a DiskDrive class.	2016-07-15 06:51:11 -04:00
Thomas Harte	1e9eedc314	Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.	2016-07-10 18:36:52 -04:00
