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	f3d9aec8fc	Fixed Electron's support for automatically booting floppy disks.	2017-01-08 14:47:41 -05:00
Thomas Harte	f61176cd7d	Reinstituted something of the don't-do-pixel-work-until-an-affecting-write-occurs optimisation.	2016-12-15 19:20:14 -05:00
Thomas Harte	be7e05e109	Started attempting to move total responsibility for display-related interrupts and RAM timing into the video.	2016-12-11 18:34:49 -05:00
Thomas Harte	c5cf8d9531	Ensured the video subsystem correctly handles requests to run over a frame boundary.	2016-12-11 16:17:51 -05:00
Thomas Harte	c43e481a33	Started factoring video out of the Electron.	2016-12-10 21:07:52 -05:00
Thomas Harte	a549fd1ecc	Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.	2016-12-10 13:42:34 -05:00
Thomas Harte	eb3a1fbfb7	Commuted remaining Electron underscores. It would be nice also to factor out the video, but the time hasn't come yet.	2016-12-03 13:01:01 -05:00
Thomas Harte	4fac538a57	Factored out the Electron's speaker and adjusted instance variable naming.	2016-12-03 12:41:02 -05:00
Thomas Harte	d1d93829cf	Factored out the Tape and switched it to postfix underscores.	2016-12-03 12:18:08 -05:00
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	4a062c616f	Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation.	2016-10-11 22:20:13 -04:00
Thomas Harte	de658b70d7	That's thread safety, subject to the async task queue being made to work...	2016-10-07 17:02:36 -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	6084020ab3	Added shift-break as a better way to boot suitable disks. Continued attempting to clean the 1770.	2016-09-25 14:11:22 -04:00
Thomas Harte	ce4100e5b9	Fixed slots for DFS and ADFS to sideways RAM; continued working on the 1770 to get as far as trying to get the body of a sector.	2016-09-24 22:04:54 -04:00
Thomas Harte	cd5939501f	Treading water some more, ensured the DFS and ADFS ROMs get to the Electron. It now even inserts the DFS ROM if it has a DFS disk image. Might need to make it a sideways RAM though? Regardless, the next job surely — surely! — has to be to stop avoiding the 1770?	2016-09-20 07:36:57 -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	ee8510984f	Added just enough wiring to restore the 2600 to functionality.	2016-09-15 19:34:45 -04:00
Thomas Harte	8c84f3581a	Attempted to bring some uniformity in application of configurations.	2016-09-08 05:32:17 -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	c0402d0c2b	Gave tapes their own namespace.	2016-08-27 17:09:45 -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	88964ceac0	Eliminated plain pointer passing for object types.	2016-07-04 19:33:55 -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	05cb47709e	Implemented Utility::Typer for the Electron. So that now also receives pastes.	2016-06-19 17:25:35 -04:00
Thomas Harte	00a9f1bf24	Fixed best-effort updater actually to run, finally moved clock rate announcement into the C++ side of things, started working on a mechanism to allow clock rate to be updated.	2016-06-16 20:39:46 -04:00
Thomas Harte	8dc66167be	Made an attempt to consolidate the Objective-C++ side of things based on the incoming CRTMachine::Machine.	2016-05-31 22:16:20 -04:00
Thomas Harte	5c4f35e13f	Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.	2016-05-31 21:23:44 -04:00
Thomas Harte	fea32869b0	Implemented what I now believe to be the real paging logic.	2016-05-05 08:28:06 -04:00
Thomas Harte	d221c712b0	Ensured GL context is active when destructing CRTOpenGL.	2016-04-24 20:34:25 -04:00
Thomas Harte	ae2760e034	Colour phase is now updated and varies per line.	2016-04-21 21:07:29 -04:00
Thomas Harte	7aa87723a9	Added: key states are all cleared if the window loses focus. Which resolves sticky key issues. Allowing me just to use command+option+O for options and map both command and option as FUNC.	2016-04-19 21:29:10 -04:00
Thomas Harte	66f2c10c04	Resolved potential crash if tape requests are made without one inserted. Softened glFinish to glFlush, though I'm still not sure I should strictly need even that.	2016-04-19 21:00:48 -04:00
Thomas Harte	6a17c2992d	Introduced a compile-time configurable audio divider, set it arbitrarily to '8' for now. Discovered why my graphics aren't centred and added a TODO.	2016-04-13 22:31:59 -04:00
Thomas Harte	2cc72169ff	Ensured machines can nominate their own aspect ratio windows. Switched to 11/10 for the Electron.	2016-04-11 23:12:56 -04:00
Thomas Harte	e617bd2bb3	Turned audio quality up to the maximum, at least for now.	2016-04-06 21:12:22 -04:00
Thomas Harte	8f87973a96	Switched to table-based byte to output conversion.	2016-04-05 22:07:10 -04:00
Thomas Harte	7838507a7a	Simplified sound generation.	2016-04-04 22:22:19 -04:00
Thomas Harte	8cd5d40e00	Made an attempt to reduce the amount of data heading to the GPU.	2016-03-22 21:16:32 -04:00
Thomas Harte	fb6fb5d948	Switched to two-phase setup to deal with OpenGL scheduling.	2016-03-20 13:50:13 -04:00
Thomas Harte	9a492ac15f	Made a further guess at the state interrupts would probably be left; slightly simplified interface.	2016-03-14 22:42:52 -04:00
Thomas Harte	fb26b38ff9	This is as simplified as things seem to be able to get without breaking at least Northern Star. Joe Blade et al remain stubbornly broken but I'm not immediately able to determine why.	2016-03-13 19:55:20 -04:00
Thomas Harte	1c4acfb599	I think this is a prima facie acceptable implementation of the fast tape hack.	2016-03-13 17:39:53 -04:00
Thomas Harte	6327311130	Made an attempt to separate and clarify on tape interrupts.	2016-03-12 20:32:26 -05:00
Thomas Harte	a89225987f	Blank lines are back.	2016-03-10 22:19:54 -05:00
Thomas Harte	b836d74e18	Believing the previous implementation to be overly complicated through premature optimisation, simplified video. It's slightly slower now. Will need work. Immediately to do: figure out how to deal with blank scan lines.	2016-03-10 22:08:50 -05:00
Thomas Harte	c7976dd657	Started trying to clean up my Outputs namespace by moving stuff related to the CRT underneath a separate subnamespace.	2016-03-08 20:49:07 -05:00
