1f56e85f6d Centralised resetting of tape files within the static analyser, having implemented it patchily. 2017-05-06 22:19:08 -04:00
Thomas Harte
e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00
Thomas Harte
f3d9aec8fc Fixed Electron's support for automatically booting floppy disks. 2017-01-08 14:47:41 -05:00
Thomas Harte
e5cc77f22d Added an extra sanity check. 2016-12-30 17:29:51 -05:00
Thomas Harte
beaa868079 Factored the MFM parser out into encodings. 2016-12-25 20:00:57 -05:00
Thomas Harte
1b15bc3a6c Started relocating the tape parsers down from static analyser to storage, to signify that they may be used by the emulation (if fast loading is supported on that machine). 2016-11-06 16:13:13 -05:00
Thomas Harte
093eb55fc6 The parsers no longer own a tape, merely taking one as an argument. So they can be an adjunct. 2016-11-06 15:25:18 -05:00
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
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
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
67b54269c9 Added typer support for loading from DFS. It'll do for now. 2016-09-24 22:52:49 -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
Thomas Harte
c9dd07cecd DFS disks are now delivered right up to the emulator's front door. So everything's in place to get started on that WD1770 nonsense. 2016-09-19 08:29:23 -04:00
Thomas Harte
e025768604 Two passes of the index hole => no sector found. 2016-09-19 08:17:07 -04:00
Thomas Harte
64f2538b1f Added CRC checking to DFS comprehension; fixed a bunch of places where I'd used Objective-C's #import rather than #include. 2016-09-19 08:16:06 -04:00
Thomas Harte
c58cdbf151 Minor tweak to support zero-length files. 2016-09-19 07:37:11 -04:00
Thomas Harte
ca4df5dd61 Introduced a full container for disk catalogues, so as also to capture non-file information, and 'completed' (i.e. albeit that CRC checking is still absent) DFS catalogue decoding. 2016-09-19 07:35:02 -04:00
Thomas Harte
231f3dd0f4 This is exactly as far as I'm going to get with DFS parsing today, I think. 2016-09-18 22:18:01 -04:00
Thomas Harte
b1e7f2dfd0 There's no cache and no CRC checking yet, but this is probably a rough outline of an FM parser. 2016-09-18 22:03:06 -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
5ebca62bba Now the CRC is a factoring out. 2016-09-18 18:35:50 -04:00
Thomas Harte
92af19098c Improved file naming. 2016-09-15 19:24:59 -04:00
Thomas Harte
27fedaf892 The error flag is no longer directly exposed. I also tweaked the Commodore import numbers just a touch. But I think I need proper calibration. 2016-09-08 21:09:05 -04:00
Thomas Harte
556b77f2fd Added some TODOs, re-enabled master Acorn decision. 2016-09-07 07:39:47 -04:00
Thomas Harte
149cbb327b Made something of a first attempt at a parser. Which is failing terribly. 2016-09-06 06:59:51 -04:00
Thomas Harte
cfe8251166 Further documented interface, fixed a potential parsing blockage. 2016-09-05 22:12:52 -04:00
Thomas Harte
05c24222d8 Liberated the tape parser template. 2016-09-05 20:02:35 -04:00
Thomas Harte
463b74301d Sought to reduce the amount of heap nonsense. 2016-09-05 19:59:58 -04:00
Thomas Harte
11850b872d Sought to emulate 0111 as a longer 0110 to test a particular HQ UEF. Some progress. Not great. 2016-09-05 18:28:43 -04:00
Thomas Harte
6239297212 Fixed off-by-one error on filename lengths and order-of-operations mistake preventing data CRC from being checked. 2016-09-05 18:15:15 -04:00
Thomas Harte
e25fee2332 I'm going back to believing in this test. 2016-09-05 17:55:40 -04:00
Thomas Harte
68874b6080 Fixed accidental implicit assumption that Acorn files will be at least two blocks. 2016-09-05 17:53:57 -04:00
Thomas Harte
93f5b5303e Factored out the stuff I expect to be common to this tape nonsense, started looking at the one currently-failing tape. More on the latter to do. 2016-09-05 17:17:52 -04:00
Thomas Harte
6f62803814 Resolved dropping of every other file. 2016-09-01 08:35:28 -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
9d7962d6c0 Closed the loop on Electron analysis for now. Including loading command detection. 2016-08-31 20:24:13 -04:00
Thomas Harte
d8c0da7ccb I think this should lead to a full representation of files on an Acorn tape, but subject to is_at_end working. 2016-08-31 19:57:09 -04:00
Thomas Harte
7b5d5858ff CRCs are just stored reversed. Of course. So this should be sufficient to load each chunk of an Acorn file. 2016-08-30 08:13:40 -04:00
Thomas Harte
b3521ed187 Started working towards capturing everything there is to know about a file. CRC calculation appears to be flawed somehow at the moment. 2016-08-30 07:38:08 -04:00
Thomas Harte
6218f05b8c This loads the name. That'll do for now. 2016-08-29 22:05:06 -04:00
Thomas Harte
963a479908 Made a quick first attempt at getting a file name from Acorn tape, failing terribly but at least formalising tapes being able to signal their end. 2016-08-29 21:53:06 -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
