Corrects some deficiencies in Vic-20 keyboard mapping.
...
... albeit without yet being clear on the wiring behind restore.

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.

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.

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.

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.

Added a decent portion of documentation. But started feeling like I should address my various ownership decisions. Which would justify a separate pull request.

Performed the normative removal from public view of Vic-20 implementation details. Which were hefty.

Remove the 6502's use of runtime polymorphism in favour of ordinary templating.

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.

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.

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.

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

Converted the TimedEventLoop and the things that sit atop it into ClockReceivers.

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.

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.

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

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

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

Implemented a catch for loading the data portion of files.

Implemented speedy header finding. So that's half of it.
2017-05-07 20:32:48 -04:00

Removed one piece of unnecessary logging.

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.

Completed curly bracket movement.

Brought the Vic-20 into suffix naming.

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

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

Added a direct-to-two-cycles emulation path for 6522 owners.

Evicted more header-resident code.

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.

Added insurance against an infinite loop should the tape be exhausted.

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

Made attempt to run at zero cost while processing tape input.
2016-09-11 17:34:02 -04:00

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

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.

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

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.

This has now successfully loaded its first PRG-as-a-tape.
