2017-09-04 14:26:04 -04:00
Thomas Harte
ee71be0e7e
Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.
2017-08-21 21:56:42 -04:00
Thomas Harte
f68565a33f
Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.
2017-08-17 10:48:29 -04:00
Thomas Harte
925e774015
Added a decent portion of documentation. But started feeling like I should address my various ownership decisions. Which would justify a separate pull request.
2017-08-16 16:23:33 -04:00
Thomas Harte
4c15e46fd1
Performed the normative removal from public view of Vic-20 implementation details. Which were hefty.
2017-08-16 16:05:30 -04:00
Thomas Harte
42b5b66305
Remove the 6502's use of runtime polymorphism in favour of ordinary templating.
2017-08-16 11:56:52 -04:00
Thomas Harte
bbb17acf3a
Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.
2017-08-03 11:50:50 -04:00
Thomas Harte
ad3a98387f
Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.
2017-08-03 11:42:31 -04:00
Thomas Harte
4abd62e62b
Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.
2017-07-27 22:05:29 -04:00
Thomas Harte
279c369a1f
Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation.
2017-07-25 22:21:09 -04:00

The 6560 is now a ClockReceiver. This reduces to zero the number of remaining instances of the text run_for_cycles in this codebase.

Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.
2017-07-22 22:17:29 -04:00
Thomas Harte
83628b285b
Experimentally turned the 6502 into a clock receiver. No problem encountered.

Thomas Harte
3f609e17b3
Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups.
2017-07-21 21:18:51 -04:00
Thomas Harte
f931cd582d
Switched to use of std::vector in those few remaining places where I was still using a unique_ptr to a native type and newing for myself. So, some of my earliest bits of code.
2017-07-16 13:54:07 -04:00
Thomas Harte
52d9ddf9e5
Gave the binary tape player a more logical assignment of wave level to output level. Which miraculously appears to have been the issue with the ZX80/81 tape loading — the inconsistency of silences seems to have been the issue.
2017-06-21 22:13:24 -04:00
Thomas Harte
eb8a2de5d6
Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.
2017-05-15 07:38:59 -04:00
Thomas Harte
0808e9b6fb
Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.
2017-05-14 22:08:15 -04:00
Thomas Harte
8e35e913bb
Formally withdrew the 'load automatically' option for the Vic, having removed that option elsewhere.

Thomas Harte
5d91a2600d
Permitted ROM-style PRGs that are not a power-of-two in size, and added extra safety checks on loading data from a tape.
2017-05-08 22:15:35 -04:00
Thomas Harte
cb66c7e2dc
Performed some minor tidying.
2017-05-08 21:05:35 -04:00

Switched to a more straightforward way of exiting from tape data loading.
2017-05-08 20:58:55 -04:00
Thomas Harte
7b43ae0a92
Implemented a catch for loading the data portion of files.
2017-05-07 22:22:59 -04:00

Implemented speedy header finding. So that's half of it.
2017-05-07 20:32:48 -04:00
Thomas Harte
0771363f3b
Removed one piece of unnecessary logging.
2017-05-06 22:22:03 -04:00
Thomas Harte
2edf73908c
Temporarily disabled the existing fast loading implementation in pursuit of another, and started trying to correct the lack of connection between the userport VIA and the tape drive.
2017-05-06 22:00:12 -04:00
Thomas Harte

Switched the typer to postfix underscores.
2016-12-03 10:55:50 -05:00
Thomas Harte
45b169f341
Made a few mapping fixes, clarified where the default reset code lives, ensured the Oric and Vic clear their keys when the typer ends.
2016-11-05 15:28:03 -04:00
Thomas Harte
338904fffe
Made similar cleanings of the Electron and Vic.
2016-11-05 15:07:57 -04:00
Thomas Harte
9fb9d92437
Made the typer much more able to help out, and thereby tidied and separated the Oric's typer.
2016-11-05 14:47:09 -04:00
Thomas Harte
4fab794747
Added a direct-to-two-cycles emulation path for 6522 owners.
2016-10-27 21:13:25 -04:00
Thomas Harte
c5948ef177
Evicted more header-resident code.
2016-10-20 21:05:32 -04:00
Thomas Harte
6d7c3f6ac2
Factored out the now-sampling binary-level tape player from the Vic and connected it up to the Oric.

The Vic-20 now inserts ROMs again.

Resolved failure to open disks that arrive through analysis.
2016-09-17 18:11:58 -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
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
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
56c0d70c1f
Gave disks their own namespace.
2016-08-27 17:15:09 -04:00

c0402d0c2b
Gave tapes their own namespace.

Added a test call, further mutated result structure.

dab3580111
Experimental: can I afford a lower sampling rate if there's a low-pass filter in effect?
2016-08-22 22:18:05 -04:00
Thomas Harte
1541273785
Moved responsibility for throwing in a low-pass filter up to the Vic, appropriately.
2016-08-21 18:13:31 -04:00
Thomas Harte
99157ad6b2
Ensured the 6560 knows its real audio clock on a PAL machine; removed some stray semicolons.
2016-08-19 13:35:34 -04:00
Thomas Harte
e985c72ce8
Removed a dead special case.
2016-08-19 12:23:06 -04:00

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
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
ca2dc6b6c4
Ensured ROMs survive in the new memory model.
2016-08-15 19:56:01 -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
547aefb696
Slightly adjusted PRG strategy, made a note about where next.
2016-08-14 16:36:42 -04:00
Thomas Harte
d9016909ed
Added some wiring for PAL/NTSC mode switching on the Vic, making an attempt to simplify the whole loop of having different clock rates.
2016-08-14 13:33:20 -04:00
Thomas Harte
a547b7e1d8
Took basic steps towards supporting memory expansions.
2016-08-13 17:21:25 -04:00
Thomas Harte
142774be37
Collapsed 6560 template to a more direct loop, albeit with quite a bit still left to fix.
2016-08-09 21:10:53 -04:00
Thomas Harte
12bad8f23f
Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue.
2016-08-09 20:41:05 -04:00
Thomas Harte
285a288c80
Switched to two cycles of options loading, meaning that they get set before files are inserted. Might need some further work?
2016-08-07 21:48:09 -04:00
Thomas Harte
be54d8040e
Made a first stab at having automatic loading be optional. But things are currently arranged such that the machine options are communicated too late to have an effect. So work to do.
2016-08-06 17:39:27 -04:00
Thomas Harte
3e65450a54
Converted the 6560 fully into a template; worked on allowing the typer to run at a much faster rate where hardware has some trigger by which it can request the next key.
2016-08-06 14:33:24 -04:00
Thomas Harte
5d40d70c92
Fixed 6560 addressing error, added an autotyper for Vic disks (more work potentially needed), fixed semantics for testing whether a 6502 is about to reset.
2016-08-01 10:32:32 -04:00
Thomas Harte
b43a7381ae
Fixed framing and first-byte-after-sync signalling. Hacked together as parts of it are, loading now appears to work!
2016-08-01 04:25:11 -04:00
Thomas Harte
740ea0b7e2
Added overflow-flag setting logic and ensured disk ROM gets through regardless of ROM/disk installation order.
2016-07-31 19:33:18 -04:00
Thomas Harte
ada2f073e0
Completed handing of the disk all the way to the 1540.
2016-07-10 16:24:46 -04:00
Thomas Harte
6cfc514c2d
Made the rote changes necessary to attempt to open and to supply a G64 to the Vic.
2016-07-10 12:57:17 -04:00
Thomas Harte
4ca6883f7c
Disabled attachment of a 1540 again, as I probably need to move to opening an actual disk image next.
2016-07-10 08:03:36 -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
c0ab45a73d
Disabled a bunch of the caveman debug logging.
2016-07-09 22:29:11 -04:00
Thomas Harte
f589d639db
Okay, so it seems that sync also works the other way around.
2016-07-09 22:25:44 -04:00
Thomas Harte
693c8b2438
After all that, it seems likely that inputs just aren't inverted for the Vic.
2016-07-09 20:03:38 -04:00
Thomas Harte
81e6cc34e5
Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus.
2016-07-07 06:57:21 -04:00
Thomas Harte
c9479f923b
The inversion of truth was clearly just a problematic API. Got explicit. LineLevel might need to become more pervasive.
2016-07-07 06:44:13 -04:00
Thomas Harte
dcb86a027a
Okay, so the 1540 doesn't toggle the actual attention line. I don't know what it does yet but this helps.
2016-07-06 22:31:14 -04:00
