Thomas Harte	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
Thomas Harte	9bbcbd1001	Renamed class, intending to turn a Disk::Drive into literally just that, and have a thing with a PLL that consumes events be a Controller.	2016-09-25 20:05:56 -04:00
Thomas Harte	de863719d0	Made a first attempt at Acorn ADFS support plus the start of a suitable analyser.	2016-09-25 17:46:11 -04:00
Thomas Harte	cd5939501f	Treading water some more, ensured the DFS and ADFS ROMs get to the Electron. It now even inserts the DFS ROM if it has a DFS disk image. Might need to make it a sideways RAM though? Regardless, the next job surely — surely! — has to be to stop avoiding the 1770?	2016-09-20 07:36:57 -04:00
Thomas Harte	0ce901bd48	Added necessary wiring to get as far as asking an arm of the analyser to check out an Acorn disk image.	2016-09-18 21:18:11 -04:00
Thomas Harte	91cd7e143b	Started on the SSD/DSD support. Realised I had ommitted multiple head support from my disk class. Fixed that.	2016-09-18 19:21:02 -04:00
Thomas Harte	180c3df2d4	Calling it 'number theory' probably isn't accurate but extracted the CRC stuff and started using it for [M]FM encoding.	2016-09-18 18:33:26 -04:00
Thomas Harte	bcf91de7e9	Declared support for the Acorn disk files, started hammering out an encoder.	2016-09-18 13:35:54 -04:00
Thomas Harte	0e44cfa8a1	Merge branch 'master' into WD1770	2016-09-18 10:34:11 -04:00
Thomas Harte	6f0b9adc3d	Factors.cpp is dead.	2016-09-18 10:23:34 -04:00
Thomas Harte	a98374995e	Cleaned up pre-analysis code.	2016-09-17 18:19:32 -04:00
Thomas Harte	e3daf80564	Added a file for the 1770, at least.	2016-09-17 18:01:00 -04:00
Thomas Harte	7c65c69e0f	Migrated to Swift 3.	2016-09-15 22:12:12 -04:00
Thomas Harte	ee8510984f	Added just enough wiring to restore the 2600 to functionality.	2016-09-15 19:34:45 -04:00
Thomas Harte	92af19098c	Improved file naming.	2016-09-15 19:24:59 -04:00
Thomas Harte	df7aed7e8b	The Commodore analyser now at least hands off to somebody else a chance to parse disks.	2016-09-13 07:26:51 -04:00
Thomas Harte	eeec516fa6	Implemented seeking on tapes, mucked about a bit more with the Commodore analyser, at least temporarily removed cropping from the Vic emulator.	2016-09-11 17:09:00 -04:00
Thomas Harte	8c84f3581a	Attempted to bring some uniformity in application of configurations.	2016-09-08 05:32:17 -04:00
Thomas Harte	bdebc18e0a	Added a header parser for Commodore tapes. No time to grab file bodies now; time to go to work.	2016-09-06 08:49:32 -04:00
Thomas Harte	8b933182af	Added enough wiring (hopefully) that the Commodore tape's GetFiles should be called when appropriate.	2016-09-06 06:39:40 -04:00
Thomas Harte	963e307d0c	Increased documentation.	2016-09-05 22:06:39 -04:00
Thomas Harte	05c24222d8	Liberated the tape parser template.	2016-09-05 20:02:35 -04:00
Thomas Harte	21e5f407d8	I need to get a bit more definitive on naming but this gets all the way to setting a configuration upon an Electron.	2016-08-31 22:03:42 -04:00
Thomas Harte	a9b67dfba0	Introduced an NSDocumentController subclass.	2016-08-31 21:21:07 -04:00
Thomas Harte	7bc2b6b161	Added the minor piece that will allow analysis results to be obtained from Objective-C, and exposed to Swift in sufficient detail for it to be able to pass on to the machine.	2016-08-31 20:43:29 -04:00
Thomas Harte	0032ad2634	Edging ever onwards; killed forced attempt at uniformity in targets, sketched out the interface for a next-file-from call to Acorn tapes.	2016-08-29 21:10:38 -04:00
Thomas Harte	d1abfc040c	Addressed my dithering here: the file format containers themselves should do nothing but inspect the data to find out whether it is of the correct format. The machine steps are there for machine-specific validation. So it's probably easier to treat a binary ROM image just as a binary ROM image. Therefore, the Acorn-specific .rom detection is now in an Acorn-specific area.	2016-08-29 08:48:49 -04:00
Thomas Harte	d9f0065154	Sketched out just enough classes to get through the get-contents-into-memory step of static analysis.	2016-08-28 12:20:40 -04:00
Thomas Harte	24938326ac	ROMs definitely have no behaviour other than responding to memory accesses. Cartridges might. So picked the more general term. Sketched out a class at least to parse PRG as though it were a cartridge. Hence the static analyser can guess at whether a PRG is a cartridge or an ordinary program.	2016-08-27 18:26:51 -04:00
Thomas Harte	a1b3a18d11	Started forcing a resolution on ROMs by doing. But have immediately misstepped. Rename coming momentarily...	2016-08-27 18:17:40 -04:00
Thomas Harte	e68ff64045	Actually, this is less prescriptive.	2016-08-27 13:42:51 -04:00
Thomas Harte	5ffd9e4f0d	This is probably how the static analyser interface will look?	2016-08-23 21:35:59 -04:00
Thomas Harte	38aec44d85	Made sufficient changes for the Vic itself to believe it can recast a PRG as a tape and insert it that way. So now the ball is in the court of: how the heck are Commodore tapes encoded?	2016-08-15 19:44:41 -04:00
Thomas Harte	58297f1baf	Performed the basic metadata and routing for opening D64 files. Realised that I wasn't actually necessarily catching exceptions properly for all file opens, and fixed.	2016-08-01 07:09:15 -04:00
Thomas Harte	89a1881fef	Started turning the 1540 into an actual disk drive.	2016-07-29 11:03:09 -04:00
Thomas Harte	0e581c7607	Factored out the stuff of running a timed event loop from the TapePlayer.	2016-07-29 07:15:46 -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	e061e849d4	Had a second bash at the PLL. Probably I should read some of the literature.	2016-07-27 16:24:24 -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	d1fe07f14d	Added test of perfect DPLL input timing.	2016-07-12 21:42:23 -04:00
Thomas Harte	75d95c0bc0	Sketched out an interface for a digial PLL. Not persuaded yet. Baby steps.	2016-07-11 22:12:58 -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
Thomas Harte	ff49857f5c	Started sketching out support for the G64 file format.	2016-07-10 10:17:53 -04:00
Thomas Harte	9e3d6b762b	Sketched out the generic interface for a disk, documenting it and the tape interface while I'm here.	2016-07-10 08:54:39 -04:00
Thomas Harte	d8334edf4a	Started trying to clean up, including commuting the C1540 source file name to match its class name but mainly by adding documentation.	2016-07-10 07:46:20 -04:00
Thomas Harte	865eb421cd	Quick on-disk tidy up.	2016-07-09 15:44:55 -04:00
Thomas Harte	7cc4bf3fe7	Hit and hope is getting me nowhere. Time to unit test this thing.	2016-07-09 15:40:25 -04:00
Thomas Harte	d2cded7b59	Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.	2016-07-05 14:55:20 -04:00
Thomas Harte	0d3d0fbe4d	Created a namespace for Commodore and an empty container file for the 1540[/1] implementation.	2016-07-05 13:28:27 -04:00
Thomas Harte	6dbf16210b	Switched protocol to meaningful name and corrected its omission from the repository.	2016-07-04 19:19:07 -04:00
