Thomas Harte	75208b0762	Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere.	2017-08-16 15:33:40 -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	968d2bb8ba	Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.	2017-07-27 21:53:45 -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	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	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	90bf6565d0	Reduced int/Cycle conversions in the Electron and on the Atari 2600, where the current framework makes it possible to do so.	2017-07-24 22:53:13 -04:00
Thomas Harte	2ff157cf7a	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.	2017-07-22 21:52:21 -04:00
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	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
