b180f04c87 Okay, so this file format wasn't what I hoped it was. It's another hack. Lots of work to do. 2016-11-26 10:19:10 +08:00
Thomas Harte
7613755f94 Fixed addressing: types are 1 and 2, not 0 and 1. 2016-11-26 10:13:12 +08:00
Thomas Harte
8499783b14 Dragged multibyte primitives and signature checks up to the base class. Implemented support for Oric MFM-style .DSK, at the file format level. 2016-11-21 20:47:16 +08:00
Thomas Harte
31c2548804 Created a base class for the boilerplate fopen stuff, switched as many classes as possible to its use, switched to postfix underscores and non-camelCase names. 2016-11-21 20:14:09 +08:00
Thomas Harte
97811fe590 Made minor fix to ensure that a header that appears to extend beyond the end of an Oric .TAP doesn't create an ostensibly endless tape. 2016-11-15 12:02:03 +08:00
Thomas Harte
fce48b9b8c I am instructed that the Oric actually catches only positive transitions, and compares the distance between those to a threshold. So here's an altered version of the tape parser that does that. 2016-11-09 06:37:10 -05:00
Thomas Harte
c257e7f58d Implemented better sync-to-zero and discovered a header counting bug plus, probably, a misleading representation of gaps in the Oric TAP decoder. 2016-11-07 20:17:06 -05:00
Thomas Harte
80702616ea Had a quick go at using the Oric parser for static analysis. Found out that synchronisation is lost. Need to investigate. 2016-11-06 22:56:38 -05:00
Thomas Harte
7205c3f82b Made an attempt to build in Oric slow/fast detection. 2016-11-06 21:31:10 -05:00
Thomas Harte
d1ef2f7c63 Made an attempt to consolidate what I learnt of Oric encoding while building this hastily and untidily directly into the Oric implementation. 
(while adding support for the slow tape encoding mode)
 2016-11-06 19:22:09 -05:00

353c1c8ea3 Shifted ownership of PETSCII -> string conversion down to the storage layer, where it's useful for tape parsing. 2016-11-06 18:43:51 -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
827a919368 This is an initial attempt at reading actual tape data. It loses sync though. 2016-11-02 22:30:53 -04:00
Thomas Harte
d3634488e6 Made an attempt better to deal with multiple-file TAPs; also started using a zero level for the header/data gap. 2016-10-24 21:59:06 -04:00
Thomas Harte
cbbd31c2e0 Explained what this recently factored-out class does, and removed code from the header. 2016-10-20 19:33:25 -04:00
Thomas Harte
cc0b70828b Removed attempt at multiple-file logic, at least for the time being. Starting to wonder whether I actually need anything beyond a literal streaming of bytes? 2016-10-16 22:15:24 -04:00
Thomas Harte
fae1bb0db9 First successful game loaded! It turns out exactly one '$' is correct. Probably. 2016-10-15 21:49:41 -04:00
Thomas Harte
952a24f769 A quick hard-wiring of the OricTAP code to get the first file in a .tap correct, damn the rest, and I'm getting some on-screen feedback. Hooray! 2016-10-15 21:39:53 -04:00
Thomas Harte
a608bbebfb Performed enough wiring to put the onus back onto OricTAP to do appropriate things. 2016-10-15 21:32:59 -04:00
Thomas Harte
6d7c3f6ac2 Factored out the now-sampling binary-level tape player from the Vic and connected it up to the Oric. 2016-10-15 21:21:18 -04:00
Thomas Harte
4f78d693e9 Reintroduced gap as a string of 1s, made an attempt to look up bit ordering. Still unclear on high/low versus low/high. 2016-10-11 08:07:51 -04:00
Thomas Harte
70f004efbb This may be feeding bits in the wrong direction or calculting the wrong parity or doing something else amiss but should now be correct as to bytes. 2016-10-11 07:57:10 -04:00
Thomas Harte
df01c78039 It's a bit of a mess but this is probably close to appropriate for Oric TAP files. 2016-10-11 07:39:48 -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
ca53fac732 Switched to assuming a single-sided disk, moved out magic constants. 2016-09-26 21:20:30 -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
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
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
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
8a1b805d11 Fixed file offset calculation for single-sided images. 2016-09-19 07:34:10 -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
d1c861d3a5 That should be that, I hope. 2016-09-18 21:09:32 -04:00
Thomas Harte
02c9a82cb5 Edging towards SSD/DSD support. Hold on! 2016-09-18 19:32:08 -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
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
Thomas Harte
d9aaf456f0 Adapted pervasively to MSB-first output. Which seems to be correct. 2016-09-18 18:46:58 -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
55a7418cbf Parameterised to perform FM and MFM encodings, at least subject to CRCs still being missing. 2016-09-18 17:16:20 -04:00
Thomas Harte
22eed60d2b Started sketching out basic MFM track encoding. Which possibly even means that the shifters don't need to be public? 2016-09-18 16:53:21 -04:00
Thomas Harte
0089c830c6 This possibly correctly encapsultes the lowest level of FM and MFM rules. 2016-09-18 14:17:06 -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
6454508db8 Added a quick bit of documentation. 2016-09-18 10:30:52 -04:00
Thomas Harte
65b568003d Clarified TODO. 2016-09-18 10:29:45 -04:00
Thomas Harte
8c2bf099ad Cut down to one GCD and clarified variable names, getting more explicit about what's going on. 2016-09-18 10:24:09 -04:00
Thomas Harte
79ef38b123 Attempted to use the new get_cycles_until_next_event method to take some repetition outside of the PLL and drive event loops. 2016-09-17 22:02:38 -04:00
Thomas Harte
dbb758aaf1 Workaround for a weird bug that suddenly appears to manifest: gzgetc is returning the file name, not bytes from the file. Seems to be related to improper initialisation of the next field within the gzFile header. I can't immediately see where ZLib intends to do that so it's a bit mysterious. But the larger-than-8 readers could probably save time by reading in blocks anyway. 2016-09-17 22:01:25 -04:00
Thomas Harte
14a9edcf5d Made an attempt to do the time base conversion upfront, saving a lot of hassle and allowing greater prediction. 2016-09-17 19:52:27 -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
Thomas Harte
e3571e8b9e Added insurance against an infinite loop should the tape be exhausted. 2016-09-12 22:22:23 -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
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
d7d5f24aab Attempted, at least, to insert a dummy byte as per the specification. 2016-09-06 21:51:04 -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
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
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
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
29c972f4b8 Added hacky segue into analysis for all Electron formats. Added analyser to try to differentiate Acorn-format ROMs from other things called .rom, which are likely to be numerous. 2016-08-28 12:43:17 -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
82c8459055 Minor tidying of namespace usage declarations. 2016-08-27 17:18:12 -04:00
Thomas Harte
56c0d70c1f Gave disks their own namespace. 2016-08-27 17:15:09 -04:00
Thomas Harte
c0402d0c2b Gave tapes their own namespace. 2016-08-27 17:09:45 -04:00
Thomas Harte
8c333059a8 Turning this into a slog: gave UEF a more appropriate name, got as far as now having to decide what to do about ROMs as to structure. I guess they're machine specific, so specific classes? 2016-08-27 16:40:21 -04:00
Thomas Harte
73ce67bee8 Added some documentation of the intention here. 2016-08-19 11:04:59 -04:00
Thomas Harte
4edd1214f1 This has now successfully loaded its first PRG-as-a-tape. 2016-08-19 10:58:42 -04:00
Thomas Harte
2935848f35 Adopted header/header/data/data pattern. But still not complete joy. 2016-08-17 08:03:34 -04:00
Thomas Harte
e5523dbbed This gets through loading the first(/only?) copy. I tried repeating it with a bit-flipped header, now I'm trying repeating the header with a different file type. More documentation searching to do, I guess. 2016-08-16 22:17:08 -04:00
Thomas Harte
1bca9aa2bb Fixed parity: now calculated from the actual byte and works the other way around. The Vic now believes it is loading the actual program. So I guess bytes, headers and the lead-in is working. 2016-08-16 21:41:09 -04:00
Thomas Harte
dfe9fb83ef This proves that bytes are being deposited properly. For the first 36 anyway, and with no announcement. 2016-08-16 21:09:50 -04:00
Thomas Harte
12f8aff65b Lengths I'd taken seem to have been for dipoles, not single poles. So I just doubled the clock rate. Also I was producing each dipole as high then low, when they should probably be low then high. The Vic now at least recognises that something is happening on the tape. 2016-08-16 19:46:53 -04:00
Thomas Harte
3a23d5d8cf Adjusted the check digit. 2016-08-15 22:44:36 -04:00
Thomas Harte
dbe47f3f45 I've obviously misunderstood something as, as far as I'm concerned, this should at least get me a 'LOADING'. 2016-08-15 22:40:05 -04:00
Thomas Harte
7994148f55 I'm starting to make a little headway, I think: this performs lead-ins and countdowns, though with no actual data or anything as helpful as that. 2016-08-15 22:10:53 -04:00
Thomas Harte
7e2b4554ea This likely forms the Commodore dipoles correctly. It just stays stuck in leader tone forever is all. 2016-08-15 20:08:50 -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
3aa40212f3 Fixed minor documentation error; admitted that this class didn't invent the idea of a pulse. 2016-08-15 19:37:21 -04:00
Thomas Harte
9d76cd9b60 Removed dead instance storage. 2016-08-04 21:41:12 -04:00
Thomas Harte
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
Thomas Harte
e57ab1025d Fixed location calculation, up to a point. 2016-08-03 22:33:00 -04:00
Thomas Harte
9af9b28baf Made very first attempt at closing the loop on this. But it's time for work. 2016-08-03 08:16:23 -04:00
Thomas Harte
e15241dc3c Added ability to query how long since the new interval was set to the timed event loop. Discovered that LCM will returning the net effect of the common factors only. Otherwise continued iterating towards time preservation. 2016-08-03 07:49:00 -04:00
Thomas Harte
a3a3486f54 Okay, it's becoming more apparent where the (very mild) complexity will be here. But started moving towards retaining rotation between tracks. 2016-08-03 07:33:26 -04:00
Thomas Harte
21f1fa37a4 Fixed Time addition, added accumulation of distance into track into the disk drive, added a short circuit for LCM. 2016-08-03 07:26:05 -04:00
Thomas Harte
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
Thomas Harte
d832e5e10d Reduced 1540 PLL to running at 4Mhz. Which is possibly correct (?) Made minor change to avoid divide if possible. 2016-08-02 21:28:50 -04:00
Thomas Harte
bc10b3ee9a It appears the problem is as simple as sectors being counted from zero. 2016-08-01 10:08:38 -04:00
Thomas Harte
f5e4ea3351 Some minor tidying, lots more of the caveman stuff as I try to determine what I'm doing wrong. 2016-08-01 09:43:08 -04:00
Thomas Harte
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
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
ee2a7c9415 Added slightly to exposition, to match other formats. 2016-08-01 06:54:57 -04:00
Thomas Harte
2799a87218 Reduced possibility of overflow on LCM, improved commenting widely, removed one stale piece of G64 bootstrapping caveman stuff. 2016-08-01 06:04:55 -04:00
Thomas Harte
198fbbedc7 Reeled back all appropriate pieces of caveman debugging. 2016-07-31 13:42:34 -04:00
Thomas Harte
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).
 2016-07-31 13:32:30 -04:00
Thomas Harte
6ee784a893 Increased logging; discovered I was packing events together too closely. Now getting some zeros. 2016-07-30 04:30:55 -04:00
Thomas Harte
fead524eb5 Attempted to give the PLL a litte extra leeway, and fixed PCMTrack length test. 2016-07-29 18:52:50 -04:00
Thomas Harte
8f62211f5e Wired up the 1540 as a PLL delegate. Which prima facie means it should start receiving a bit stream. Except that I clearly have something in the timing way off — either my flux transitions are far too short or I need to significantly increase the clock rate on the PLL. 2016-07-29 12:08:18 -04:00
Thomas Harte
89a1881fef Started turning the 1540 into an actual disk drive. 2016-07-29 11:03:09 -04:00
Thomas Harte
6532b3a8c8 Filled in a calculation of clocks per bit that'll do. 2016-07-29 07:51:07 -04:00
Thomas Harte
f984de42a3 Took some small steps towards having a disk drive that at least can select a track and pump relevant events into a PLL. 2016-07-29 07:31:02 -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
5c1614ce7b Attempted to simplify, very slightly. 2016-07-28 14:35:39 -04:00
Thomas Harte
015cea494d Switched to a much-more straightforward PLL. I think I'm just fiddling now rather than moving forwards. Probably time to move on? 2016-07-28 11:32:14 -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
63f39608a6 Added just enough to get back to a working build. 2016-07-15 20:35:19 -04:00
Thomas Harte
165dbd9651 Started fleshing this out a bit. Hopefully. 2016-07-15 08:28:34 -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
6afd619791 Eliminated floating point arithmetic. 2016-07-14 19:47:00 -04:00
Thomas Harte
6b4fec37ff Moved down to a single divide. 2016-07-14 19:45:08 -04:00
Thomas Harte
481475a0f4 Switched to a full-on linear regression. Which causes the current tests to pass. 2016-07-14 19:42:01 -04:00
Thomas Harte

94db45456e Started sketching out the basic form here, albeit that it doesn't yet do _the only thing it advertises itself as useful for_. 2016-07-12 20:23:56 -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
66895d3ac7 Actually, I think this is the correct conversion from received speed to clock rate. It'll become obvious if it's not when I get back to working on the 1541 itself. 2016-07-10 18:24:12 -04:00
Thomas Harte
19ee430d4a Made an effort to support zoned tracks, at least. 2016-07-10 18:07:53 -04:00
Thomas Harte
6593caca93 Switched to a probably more helpful way around of expecting bits in bytes. 2016-07-10 16:21:52 -04:00
Thomas Harte
845a00ccef Attempted via linear search to implement PCMTrack::get_next_event. 2016-07-10 16:17:25 -04:00
Thomas Harte
f9510c1b67 Put sufficiently much of PCMTrack into place to get to a stored list of segments, having determined a common clock rate between them and therefore a complete track length. 2016-07-10 16:10:05 -04:00
Thomas Harte
4ae9f5ad5d Added preliminaries of reading the speed zone information. 2016-07-10 13:42:45 -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
c306d705e1 Made a quick first attempt at all-the-way-through tape wiring for the Vic. 2016-06-26 19:43:09 -04:00
Thomas Harte
37ba42a52f Factored out the stuff of playing a tape, started basic sketch of the Vic-related classes. 2016-06-26 19:03:57 -04:00
Thomas Harte
ee19417ded Made an attempt quickly to implement parsing of the Commodore .TAP file format. 2016-06-25 16:09:32 -04:00
Thomas Harte
21ca1ef86b Started attempting to clarify instance variable usage. 2016-03-12 23:19:10 -05:00
Thomas Harte
2b8fb5b615 Made an attempt to fix my 0114 implementation. 2016-02-20 23:13:58 -05:00
Thomas Harte
f7fc7cb932 Implemented some portion of 0114; ensured I'm safely skipping chunks in all cases. 2016-02-20 22:18:00 -05:00
Thomas Harte
ec3cccbb0d Working towards HQ UEF support: fixed bug whereby writing to tape output would reset input pulse stepper; added support for chunk 0116 and approximate support for 0113. 2016-02-20 22:03:14 -05:00
Thomas Harte
2e3ba6bbb2 Removed some logging. 2016-02-07 14:42:40 -05:00
Thomas Harte
adc6838ba0 Continued slow migration of shader ownership to CRT. Attempted to start debugging the tape interface. 2016-01-27 21:35:57 -05:00
Thomas Harte
e65cd4cf06 Some data is marginally reaching the CPU from the tape. 2016-01-19 22:05:34 -05:00
Thomas Harte
832797182f Update TapeUEF.cpp 
Corrected chunk for which _tone_length is used, definition of a carrier tone chunk.
 2016-01-19 18:59:10 -05:00
Thomas Harte
127684c590 With silence and high tone implemented, this may well hit a large proportion of existing files. 2016-01-18 19:45:14 -06:00
Thomas Harte
7d6214e078 This likely gets chunks 0100 and 0102 correct. 2016-01-18 19:37:36 -06:00
Thomas Harte
5a39e42413 Wired up enough such that some basic attempt at parsing a UEF occurs.` 2016-01-18 17:06:09 -06:00
Thomas Harte
2779f0e569 Statred working on support for at least the most fundamental file format. 2016-01-18 15:46:41 -06:00
