Thomas Harte	c097886d00	Installed hoglet's BCDTest as a formal part of the test suite; removed some redundant semicolons in the Wolfgang Lorenz tests while I was here.	2016-10-04 07:52:44 -04:00
Thomas Harte	f9ee6803df	It's likely this should be set at startup too, based on latest info.	2016-10-03 22:16:10 -04:00
Thomas Harte	f1af6ef8b6	Merge pull request #53 from TomHarte/BCDTest ... Resolves failure of the jsbeeb BCDTest.ssd	2016-10-03 22:07:20 -04:00
Thomas Harte	fa7c64bb5d	Eventually reached an implementation of ADC that continues to satisfy all the formalised unit tests while also satisfying the manual BCDTest, that I need to find a way to formalise. I fixed the unit tests for Swift 3 while here, and attempted to do some unrelated NIB stuff with no real success.	2016-10-03 22:03:39 -04:00
Thomas Harte	97304e22f0	Adjusted per tests on StarDot; it appears the tape interrupts may fire during audio output, as if in tape output mode.	2016-10-03 20:03:14 -04:00
Thomas Harte	dae6b45464	Ensured the always-on bit of the interrupt status register is indeed on.	2016-10-03 19:15:31 -04:00
Thomas Harte	6ecd8aac61	Merge pull request #52 from TomHarte/SingleDocument ... Collapses Mac binding down to a single NSDocument	2016-10-03 08:02:30 -04:00
Thomas Harte	cfdd5fb686	By removing its status as a special case, eliminated the Atari 2600 document. It's fairly clear that my date with doing joysticks properly can be deferred only so much longer but this is no worse than previously things were.	2016-10-03 08:01:04 -04:00
Thomas Harte	bf468db73d	Migrated the Vic document to a mere options panel.	2016-10-03 07:42:05 -04:00
Thomas Harte	9e6e84647e	Quick formatting fix.	2016-10-02 22:06:28 -04:00
Thomas Harte	f28881ec6b	... and with the return of stored options and the shift of the aspect ratio to somewhere else (to sit, temporarily), the Electron document is the first of the gang to die.	2016-10-02 22:04:47 -04:00
Thomas Harte	19457621d8	Redistributed ownership of the user defaults key prefix, the Electron now works other than that settings aren't retained.	2016-10-02 21:56:50 -04:00
Thomas Harte	f1b99263e0	Relocated responsibility for loading ROMs, giving an Electron that 'works' (i.e. options aside) again.	2016-10-02 20:39:06 -04:00
Thomas Harte	989a1581da	Migrated analysis logic from the document controller to the document.	2016-10-02 17:04:14 -04:00
Thomas Harte	0c75c2fc41	Disabled all machine-specific document code, to force the migration of functionality. The 2600 works other than the little matter of input.	2016-10-02 16:57:57 -04:00
Thomas Harte	6c6e9830dd	Started factoring the options panels out, in the hope that they'll become the only machine-specific thing. At least in the short term.	2016-10-02 16:31:50 -04:00
Thomas Harte	2411f192f7	Switched back to full typing, even for DFS loading. It saves having to worry about sideways RAM filing systems and shift (if that's even the issue).	2016-10-01 21:09:28 -04:00
Thomas Harte	cd1ab09701	The Vic-20 now inserts ROMs again.	2016-09-29 20:15:25 -04:00
Thomas Harte	abf47efd40	Factored out Commodore is-a-ROM test, allowing it to be used from the Commodore analyser and thereby allowing ROMs to get as far as the machine again.	2016-09-29 19:39:13 -04:00
Thomas Harte	4010f36238	Ensured tape-formatted PRGs reach a conclusion.	2016-09-29 19:12:26 -04:00
Thomas Harte	6c449e7936	Merge pull request #51 from TomHarte/WD1770 ... Adds FM and MFM encoding logic, SSD, DSD, ADF file support, and an emulated WD1770	2016-09-28 21:32:08 -04:00
Thomas Harte	79412dc84d	Upped MFM clock cycles, switched back to using the typer for the ADFS and adjusted ADFS ROM slots.	2016-09-28 21:28:34 -04:00
Thomas Harte	91235c7fd7	Fixed issue whereby parts of data that merely looked like index or ID address marks within tracks caused a resynchronisation of the tokeniser.	2016-09-27 07:36:37 -04:00
Thomas Harte	ca53fac732	Switched to assuming a single-sided disk, moved out magic constants.	2016-09-26 21:20:30 -04:00
Thomas Harte	6330e5706c	Fixed seek verify. First ADFS directory is visible.	2016-09-25 21:44:46 -04:00
Thomas Harte	4db086949a	Made an attempt to add MFM decoding to the 1770; ensured something is returned when reading the Plus 3 status register again.	2016-09-25 21:38:52 -04:00
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	7f4c78139c	Attempted to ensure that ADFS disks get to an appropriately-configured Electron. Not immediately sure why the shift press isn't working; doesn't need to be dealt with immediately.	2016-09-25 19:59:46 -04:00
Thomas Harte	523dbb9678	This'll do for getting the ADF into the machine.	2016-09-25 18:32:26 -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	6084020ab3	Added shift-break as a better way to boot suitable disks. Continued attempting to clean the 1770.	2016-09-25 14:11:22 -04:00
Thomas Harte	a538b45213	Sought to implement the verify step of type 1 commands.	2016-09-25 09:54:49 -04:00
Thomas Harte	67b54269c9	Added typer support for loading from DFS. It'll do for now.	2016-09-24 22:52:49 -04:00
Thomas Harte	0918751802	Fixed stepping out.	2016-09-24 22:48:45 -04:00
Thomas Harte	9e1d4c8b01	Fixed an initial setup error with seek.	2016-09-24 22:43:12 -04:00
Thomas Harte	d50629e6aa	This is clearly the winning solution. Edited down.	2016-09-24 22:36:38 -04:00
Thomas Harte	07ff5138b7	The catalogue now loads.	2016-09-24 22:35:34 -04:00
Thomas Harte	1b69ad0fd4	This attempts to implment sector reading. DFS reports an error.	2016-09-24 22:29:02 -04:00
Thomas Harte	ce4100e5b9	Fixed slots for DFS and ADFS to sideways RAM; continued working on the 1770 to get as far as trying to get the body of a sector.	2016-09-24 22:04:54 -04:00
Thomas Harte	7154e8986e	Fixed stepping delay.	2016-09-24 20:16:23 -04:00
Thomas Harte	53522e28e2	Performed an about-face on how this should probably be implemented. Now forsaking the state machine in favour of a macro'd switch-for-cooperative-event-based-messaging implementation. Let's see how this ends up looking.	2016-09-24 20:12:45 -04:00
Thomas Harte	88bbeedad3	Set actual bit length.	2016-09-22 21:28:23 -04:00
Thomas Harte	75eb62b577	One painful step at a time, this now starts the disk rotating and gets as far as deciding whether it's about to head off on a read or a write.	2016-09-22 21:25:31 -04:00
Thomas Harte	8db0030068	Fixed ROM loading by the Electron, turned the WD1770 into a 'disk drive' (it'll do for now), persuaded it to get all the way through a very specifically convenient type 1 command.	2016-09-20 22:14:33 -04:00
Thomas Harte	7a34ae0da6	This is the start of my slog through type 1 commands. I kind of need to figure out what I'm doing about drives and PLLs now though.	2016-09-20 16:58:23 -04:00
Thomas Harte	3b97b038b9	Corrected and sketched out state machine far enough to get to a complaint about unhandled work.	2016-09-20 15:56:31 -04:00
Thomas Harte	e358057440	Added a WD1770 run_for_cycles call. So I really can now move that as far as reporting that it has no disk?	2016-09-20 07:42:17 -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	a9e65e9b7a	Tweaked disk side density, added call-outs to a WD1770 if the Electron had one (albeit without run_for_cycles yet as I need to figure out the clock rate), added a shell of the basic functions of the WD1770. No implementation yet.	2016-09-19 22:06:56 -04:00
