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

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

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

a6354ebb01 Reimplemented PCMTrack to use PCMSegmentEventSource, eliminating code duplication. 2016-12-18 21:37:05 -05:00

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

0dc2aa6454 Commuted all of 'Storage' other than 'Tape' to postfix underscores. 2016-12-03 11:59:28 -05:00

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

56c0d70c1f Gave disks their own namespace. 2016-08-27 17:15:09 -04:00

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

e57ab1025d Fixed location calculation, up to a point. 2016-08-03 22:33:00 -04:00

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

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

198fbbedc7 Reeled back all appropriate pieces of caveman debugging. 2016-07-31 13:42:34 -04:00

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).

6ee784a893 Increased logging; discovered I was packing events together too closely. Now getting some zeros. 2016-07-30 04:30:55 -04:00

fead524eb5 Attempted to give the PLL a litte extra leeway, and fixed PCMTrack length test. 2016-07-29 18:52:50 -04:00

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

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.

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
