Thomas Harte	a49594c6a3	Tweaks Vic20 Machine parent class order so that when turned into a CRTMachine, still successfully dynamically casts as a ConfigurationTarget. ... More thorough thought is required.	2017-09-04 20:56:00 -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	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	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	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	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	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	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	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	1b1a8d3e52	Brought the Vic-20 into suffix naming.	2016-12-03 13:30:27 -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	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	142254a478	Resolved failure to open disks that arrive through analysis.	2016-09-17 18:11:58 -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	8c84f3581a	Attempted to bring some uniformity in application of configurations.	2016-09-08 05:32:17 -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	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	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
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	285a288c80	Switched to two cycles of options loading, meaning that they get set before files are inserted. Might need some further work?	2016-08-07 21:48:09 -04:00
Thomas Harte	be54d8040e	Made a first stab at having automatic loading be optional. But things are currently arranged such that the machine options are communicated too late to have an effect. So work to do.	2016-08-06 17:39:27 -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	740ea0b7e2	Added overflow-flag setting logic and ensured disk ROM gets through regardless of ROM/disk installation order.	2016-07-31 19:33:18 -04:00
Thomas Harte	6cfc514c2d	Made the rote changes necessary to attempt to open and to supply a G64 to the Vic.	2016-07-10 12:57:17 -04:00
Thomas Harte	d8334edf4a	Started trying to clean up, including commuting the C1540 source file name to match its class name but mainly by adding documentation.	2016-07-10 07:46:20 -04:00
Thomas Harte	c0ab45a73d	Disabled a bunch of the caveman debug logging.	2016-07-09 22:29:11 -04:00
Thomas Harte	f589d639db	Okay, so it seems that sync also works the other way around.	2016-07-09 22:25:44 -04:00
Thomas Harte	693c8b2438	After all that, it seems likely that inputs just aren't inverted for the Vic.	2016-07-09 20:03:38 -04:00
Thomas Harte	81e6cc34e5	Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus.	2016-07-07 06:57:21 -04:00
Thomas Harte	c9479f923b	The inversion of truth was clearly just a problematic API. Got explicit. LineLevel might need to become more pervasive.	2016-07-07 06:44:13 -04:00
Thomas Harte	dcb86a027a	Okay, so the 1540 doesn't toggle the actual attention line. I don't know what it does yet but this helps.	2016-07-06 22:31:14 -04:00
Thomas Harte	428fcdb978	Centralised and improved serial logging.	2016-07-06 07:46:21 -04:00
Thomas Harte	11fc43aa04	Made an attempt to allow the 1540 to talk back to the Vic, and to receive interrupts. Also slightly disambiguated debugging logging.	2016-07-05 19:12:43 -04:00
Thomas Harte	d16b79073e	Further fleshing out: added a serial port for the serial bus.	2016-07-05 17:27:02 -04:00
Thomas Harte	86dabd007b	Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful.	2016-07-05 16:39:18 -04:00
Thomas Harte	a25fcc7190	Made a first attempt at wiring back serial port input.	2016-07-05 16:10:54 -04:00
