Thomas Harte	5408efe9b5	Flags obvious default options within the 6560, Vic-20 and DynamicMachine.	2017-11-12 16:41:09 -05:00
Thomas Harte	ff7ba526fb	Corrects improper initialisation order on the 6560.	2017-11-10 22:05:35 -05:00
Thomas Harte	ad9df4bb90	Commutes uint8_t *, uint16_t *, uint32_t *, size_t, off_t and long to functional-style casts.	2017-10-21 22:30:15 -04:00
Thomas Harte	5e3e91373a	Switches all unsigned int and double casts to functional style.	2017-10-21 19:49:04 -04:00
Thomas Harte	edb9fd301c	Begins this project's conversion to functional-style casts.	2017-10-03 22:04:15 -04:00
Thomas Harte	e208f03636	Corrects the US colour palette, effectively undoing what was a mistaken adjustment for the time when Oric-centric phase alignment was built into the CRT based on a false calculation that it wouldn't affect the machines that generate chrominance functionally.	2017-08-16 09:58:34 -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	8361756dc4	Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.	2017-07-27 07:40:02 -04:00
Thomas Harte	75d67ee770	Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.	2017-07-25 20:20:55 -04:00
Thomas Harte	a1e9a54765	Eliminated redundant uses of ClockReceiver and sought to ensure that proper run_fors are inherited all the way down.	2017-07-25 20:09:13 -04:00
Thomas Harte	40339a12e1	Formalised the use of a cycles count with a divider, bringing a few additional plain-int users into the fold.	2017-07-25 07:15:31 -04:00
Thomas Harte	a1a3aab115	Fixed implicit sign conversion.	2017-07-24 22:40:15 -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	b7f88e8f61	Filter is now a ClockReciever, affecting all sound output devices.	2017-07-24 21:29:13 -04:00
Thomas Harte	12f7e1b804	Enshrined a default colour burst amplitude. Which now everybody relies on. The 102 figure is derived from the burst apparently being 40 IRE.	2017-07-07 23:35:14 -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	e270b726b3	Tweaked blue, increased saturation.	2017-05-13 22:01:02 -04:00
Thomas Harte	44ce7fa54c	Corrected luminances across the board, and PAL colours.	2017-05-13 21:50:09 -04:00
Thomas Harte	b0142cf050	Made an updated stab at NTSC colours.	2017-05-13 14:29:36 -04:00
Thomas Harte	a340331229	Introduced 1-bit of saturation, returning black and white as black and white.	2017-05-11 21:31:58 -04:00
Thomas Harte	15d17c12d5	Switched the 6560 to two bytes per pixel, since one isn't sufficient for precision and because mixing up the implementation might help me to figure out what's amiss.	2017-05-09 21:22:01 -04:00
Thomas Harte	5998123868	Added some consts, for a minor safety improvement.	2017-05-06 19:53:24 -04:00
Thomas Harte	e01f3f06c8	Completed curly bracket movement.	2017-03-26 14:34:47 -04:00
Thomas Harte	ca50606e1d	Restored Vic audio.	2016-12-03 17:10:47 -05:00
Thomas Harte	36bc558798	Converted all 'Components' to postfix underscores.	2016-12-03 10:51:09 -05:00
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	c783090980	It turns out that the Vic has a 1.6Khz low-pass filter. So added that.	2016-08-21 12:13:41 -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	902c0f967a	Implements known phase pattern for PAL output.	2016-08-17 08:09:48 -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	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	c6e046253e	Shunted code for the main part up into the header, in advance of turning it into a template so as to bring it inside the normal orthodoxy.	2016-08-05 19:13:49 -04:00
Thomas Harte	88964ceac0	Eliminated plain pointer passing for object types.	2016-07-04 19:33:55 -04:00
Thomas Harte	de5d2f1113	Ensured the line counter increments late on NTSC.	2016-06-27 22:12:55 -04:00
Thomas Harte	359ffb9aa7	Made some attempt to implement what appears to be the proper address generation logic.	2016-06-23 07:32:24 -04:00
Thomas Harte	b753690d5e	Made an attempt to adjust the 6560 to a model compatible with that advocated by the available documentation. Exact decision timing may need further work.	2016-06-21 22:12:01 -04:00
Thomas Harte	ce2f5515c0	Made some minor documentation improvements, killed 6522.cpp as the 6522 is going to be a template only, attempting to promote good inlining behaviour.	2016-06-19 18:11:37 -04:00
Thomas Harte	ce7488dd30	Added support for _invertedCells. Treading water a little before making real changes.	2016-06-14 21:06:29 -04:00
Thomas Harte	926f819e3b	Added some documentation, made the speaker private.	2016-06-14 20:00:16 -04:00
Thomas Harte	fdc854c0c2	Fixed tone channels; made an attempt at loading PRGs that are supposed to go into RAM.	2016-06-13 21:49:59 -04:00
Thomas Harte	efcb196ef7	Made a complete attempt at the tone channels.	2016-06-13 20:59:01 -04:00
Thomas Harte	5fc36b956c	Attempted most basic sketching of a container for Vic audio.	2016-06-13 19:30:52 -04:00
Thomas Harte	e10535181d	Made an attempt to implement interlaced video.	2016-06-12 22:27:58 -04:00

Thomas Harte	1a2b18f93b	Steps towards CPU mapping; diagnostic.	2016-06-12 17:27:57 -04:00
Thomas Harte	ed76e36b18	Made basic attempt at 16-line character mode.	2016-06-12 11:23:57 -04:00
Thomas Harte	c7c55528e2	Realised that registers appear also to be readable.	2016-06-06 20:29:39 -04:00
Thomas Harte	e8cb674073	Made some attempt at colours, at least.	2016-06-06 20:18:24 -04:00
Thomas Harte	64539a2b24	Advanced to having some characters displayed, even though they're obviously very much incorrect and the display is still rolling.	2016-06-06 07:35:35 -04:00
Thomas Harte	79e05a2413	Without yet figuring out what vertical sync is meant to do, moved just about far enough forwards to see _something_ that hopefully I can soon discern characters within.	2016-06-05 18:02:49 -04:00
Thomas Harte	444d3b69b6	Made some elementary attempt to hit something like the correct states within the VIC.	2016-06-05 17:06:10 -04:00
Thomas Harte	9e9e50edb1	Added guess on how colour memory and the 12-bit bus possibly works.	2016-06-05 16:28:06 -04:00
Thomas Harte	3be1ce457b	Made some attempt at discerning fields.	2016-06-05 14:05:31 -04:00
Thomas Harte	9566c87532	Added enough to the machine that the 6560 can now produce output if it wishes.	2016-06-05 12:11:12 -04:00
Thomas Harte	f922d38ed2	The Vic now captures the ROMs sent to it and has just enough infrastructure to get to a black screen. Progress!	2016-06-05 10:51:07 -04:00
