8992feb8cd Completed a first parse at the GCR parser, proving how incredibly slow my drive is. 2016-09-15 07:54:42 -04:00
Thomas Harte
9d6dcb80a7 Started work on a GCR parser and the helper functions that lie behind that. 2016-09-13 21:53:36 -04:00

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
e3571e8b9e Added insurance against an infinite loop should the tape be exhausted. 2016-09-12 22:22:23 -04:00

c3a795328d Windows have titles again. Also I've owned up to not knowing how to edit UEFs right now. 2016-09-12 22:15:38 -04:00
Thomas Harte
40660fe680 Made yet another guess at Commodore analysis. Elevated fast tape-related unnatural speed up to the OS-side mechanisms. 2016-09-12 22:06:03 -04:00
Thomas Harte
e54a2326a3 Made attempt to run at zero cost while processing tape input. 2016-09-11 17:34:02 -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

1ca4a2a012 Sought to be more intelligent in handling cases where the two parts of a header or data field don't match — if either looks good then use it in isolation. 2016-09-10 17:01:17 -04:00
Thomas Harte
a5b17932ca Attempted further to improve memory model guesswork. With many further improvements to make... 2016-09-08 21:09:37 -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

1de6097f06 Shuffled C stuff out on top. 2016-09-08 21:08:03 -04:00
Thomas Harte
24251a2768 Negligible indentation fix. 2016-09-08 07:49:43 -04:00
Thomas Harte
01e5dae512 Threw in 300-baud support. Why not? 2016-09-08 07:48:20 -04:00
Thomas Harte
3e925e80a3 Added a field-filling constructor for pulses. 2016-09-08 07:41:44 -04:00
Thomas Harte
1e7b5330f5 More or less rewrote, to use a filled-per-chunk buffer of upcoming pulses rather than working them out as requests come. Which is more straightforward — all the code for a particular chunk goes in exactly one place — and much easier to extend. So threw in a provisional 0104 implementation. 2016-09-08 07:41:26 -04:00
Thomas Harte
2b053436e5 Missed from previous commit; removed assumption that get_next_data always succeeds. 2016-09-08 07:39:43 -04:00
Thomas Harte
54557d7f13 Added reminder, ensured the couldn't-find-data case doesn't cause a crash. Though it should imply some manual investigation. 2016-09-08 07:39:17 -04:00
Thomas Harte
908dc40569 If loading automatically, assume that whatever was in the machine target set up the machine and don't override it. Too dodgy? More thought required. 2016-09-08 07:38:34 -04:00
Thomas Harte
8c84f3581a Attempted to bring some uniformity in application of configurations. 2016-09-08 05:32:17 -04:00
Thomas Harte
50175a9aed Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr. 2016-09-07 22:17:19 -04:00
Thomas Harte
556b77f2fd Added some TODOs, re-enabled master Acorn decision. 2016-09-07 07:39:47 -04:00
Thomas Harte
6522a9a6c2 Pulled the strands together provisionally to complete Commodore ROM-format tape parsing. Things are going to get complicated if or when I need to tackle turbo loaders. 2016-09-07 07:34:48 -04:00
Thomas Harte
d66516fd62 Finished parser for data blocks. 2016-09-06 22:10:33 -04:00
Thomas Harte
d7d5f24aab Attempted, at least, to insert a dummy byte as per the specification. 2016-09-06 21:51:04 -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
8901e94f0f Fixed: was counting between low->high transitions rather than vice versa by adding low time then checking. 2016-09-06 07:06:46 -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
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
cfe8251166 Further documented interface, fixed a potential parsing blockage. 2016-09-05 22:12:52 -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
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
bdc6a5635f Merge branch 'master' of github.com:TomHarte/CLK 2016-08-31 21:21:37 -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
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
