f6fb368d88 Allows the fast-tape mechanism to take ownership of tape handling.
Any successful fast tape interaction will now permanently pause the tape until a failed interaction occurs. This may or may not be a good idea.

286259c83b Adds missing 6560 update hooks. 2018-03-29 20:49:36 -04:00
Thomas Harte
ec353ce663 Makes minor Vic-20 optimisations.
Specifically: the 6560 is updated only upon writes (more nuance can arrive), and tape sleeps are observed.

6d464557a0 Reintroduces a warm-up run for the C1540.
That simulates the normal real-life scenario of switching the drive on slightly before the computer, and causes it to function correctly from immediate fast typing on an American Vic.

Also switches a couple of casts within the C1540 to functional style.

6b1eef572b Eliminates diamond inheritance of KeyboardMachine::Machine by typers.
Specifically by pulling the key action stuff into a purely abstract class [/interface]. Takes the opportunity to unpublish a bunch of machine details.

204d5cc964 Extends JoystickMachine protocol to cover ColecoVision use case.
Also thereby implements input on the ColecoVision, in theory at least. No input is being fed though, so...

Thomas Harte
4f289ab10b Corrects some deficiencies in Vic-20 keyboard mapping.
... albeit without yet being clear on the wiring behind restore.
2017-10-12 22:33:00 -04:00
Thomas Harte
78ee46270b Transfers possession of keyboard mappings from the Mac side over to individual machines.
Specifically by establishing an intermediate representation of a useful mix between the American and British IBM and Mac keyboard layouts, and routing through that.
2017-10-12 22:25:02 -04:00
Thomas Harte
24b3faa427 Deconstitutes the 6522 into component parts, templated and non-templated.
Adjusts the Oric, Vic-20 and C-1540 accordingly, albeit with the quickest possible solutions.
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
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
Thomas Harte
c77a83d86f The 6560 is now a ClockReceiver. This reduces to zero the number of remaining instances of the text run_for_cycles in this codebase. 2017-07-24 22:38:35 -04:00
Thomas Harte
9435c1e12a The 1540 is now a ClockReceiver. 2017-07-24 22:32:41 -04:00
Thomas Harte
efdac2ce8c The 6522 is now a ClockReceiver. 2017-07-24 22:29:09 -04:00
Thomas Harte
8a2bdb8d22 Converted the TimedEventLoop and the things that sit atop it into ClockReceivers. 2017-07-24 21:19:05 -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
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. 2017-05-14 16:59:24 -04:00
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
Thomas Harte
61f8f2f18c 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
Thomas Harte
2807e3134f 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
e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00
Thomas Harte

Thomas Harte
2003b514aa 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. 2016-10-15 21:21:18 -04:00
Thomas Harte
cd1ab09701 The Vic-20 now inserts ROMs again. 2016-09-29 20:15:25 -04:00
Thomas Harte
142254a478 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
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
Thomas Harte
c0402d0c2b Gave tapes their own namespace. 2016-08-27 17:09:45 -04:00
Thomas Harte
55ada536ac Added a test call, further mutated result structure. 2016-08-27 14:25:16 -04:00
Thomas Harte
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
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
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
