Thomas Harte	d9f0065154	Sketched out just enough classes to get through the get-contents-into-memory step of static analysis.	2016-08-28 12:20:40 -04:00
Thomas Harte	24938326ac	ROMs definitely have no behaviour other than responding to memory accesses. Cartridges might. So picked the more general term. Sketched out a class at least to parse PRG as though it were a cartridge. Hence the static analyser can guess at whether a PRG is a cartridge or an ordinary program.	2016-08-27 18:26:51 -04:00
Thomas Harte	a1b3a18d11	Started forcing a resolution on ROMs by doing. But have immediately misstepped. Rename coming momentarily...	2016-08-27 18:17:40 -04:00
Thomas Harte	e68ff64045	Actually, this is less prescriptive.	2016-08-27 13:42:51 -04:00
Thomas Harte	5ffd9e4f0d	This is probably how the static analyser interface will look?	2016-08-23 21:35:59 -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	58297f1baf	Performed the basic metadata and routing for opening D64 files. Realised that I wasn't actually necessarily catching exceptions properly for all file opens, and fixed.	2016-08-01 07:09:15 -04:00
Thomas Harte	89a1881fef	Started turning the 1540 into an actual disk drive.	2016-07-29 11:03:09 -04:00
Thomas Harte	0e581c7607	Factored out the stuff of running a timed event loop from the TapePlayer.	2016-07-29 07:15:46 -04:00
Thomas Harte	e55db0cfe8	Made an attempt to eliminate creeping tape processing accuracy misses, which implied factoring out the GCM and LCD functions, which I then felt didn't really amount to signal processing.	2016-07-29 05:19:01 -04:00
Thomas Harte	e061e849d4	Had a second bash at the PLL. Probably I should read some of the literature.	2016-07-27 16:24:24 -04:00
Thomas Harte	0aa90b943b	Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower. ... Started sketching out a DiskDrive class.	2016-07-15 06:51:11 -04:00
Thomas Harte	d1fe07f14d	Added test of perfect DPLL input timing.	2016-07-12 21:42:23 -04:00
Thomas Harte	75d95c0bc0	Sketched out an interface for a digial PLL. Not persuaded yet. Baby steps.	2016-07-11 22:12:58 -04:00
Thomas Harte	1e9eedc314	Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.	2016-07-10 18:36:52 -04:00
Thomas Harte	ff49857f5c	Started sketching out support for the G64 file format.	2016-07-10 10:17:53 -04:00
Thomas Harte	9e3d6b762b	Sketched out the generic interface for a disk, documenting it and the tape interface while I'm here.	2016-07-10 08:54:39 -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	865eb421cd	Quick on-disk tidy up.	2016-07-09 15:44:55 -04:00
Thomas Harte	7cc4bf3fe7	Hit and hope is getting me nowhere. Time to unit test this thing.	2016-07-09 15:40:25 -04:00
Thomas Harte	d2cded7b59	Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.	2016-07-05 14:55:20 -04:00
Thomas Harte	0d3d0fbe4d	Created a namespace for Commodore and an empty container file for the 1540[/1] implementation.	2016-07-05 13:28:27 -04:00
Thomas Harte	6dbf16210b	Switched protocol to meaningful name and corrected its omission from the repository.	2016-07-04 19:19:07 -04:00
Thomas Harte	6419d9c485	Added a single IRQ test case, discovering that I'm two cycles short. Whoops!	2016-06-28 21:29:43 -04:00
Thomas Harte	6027cba95f	Factored out the stuff of pushing a fast-loading option onwards and storing it within the user defaults.	2016-06-27 21:38:14 -04:00
Thomas Harte	ee19417ded	Made an attempt quickly to implement parsing of the Commodore .TAP file format.	2016-06-25 16:09:32 -04:00
Thomas Harte	4db61d98f4	Killed the .cpp.	2016-06-19 20:21:38 -04:00
Thomas Harte	7cf6008e7c	Started some very basic RIOT unit tests; corrected to pass.	2016-06-19 20:12:47 -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	e7aeed2f03	Established a general pattern for machines that can type things. Started working on the Vic typing itself.	2016-06-19 13:10:52 -04:00
Thomas Harte	06fb2ff1c7	Started endeavouring to sketch out the boilerplate for writing a 6522 test harness. Added a default implementation of synchronise to the 6522 too, since not everybody is going to want one.	2016-06-18 09:28:46 -04:00
Thomas Harte	530cf3dcbb	Made an attempt to consolidate serialisation and clock rate adherence, allowing a floating-point clock rate.	2016-06-16 18:04:54 -04:00
Thomas Harte	ce59ad1911	Minor on-disk shuffle, to try to clarify ownership of responsibility.	2016-06-15 08:11:30 -04:00
Thomas Harte	e0baaf17f1	Added class prefix.	2016-06-15 08:07:25 -04:00
Thomas Harte	6522530e1c	Actually, I'm dithering over whether the 6522 should be an ordinary class or a curiously-recurring template. But it'll need a file, definitely.	2016-06-06 21:56:02 -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
Thomas Harte	8052ce9223	System ROMs are now supplied to the Vic-20 wrapper, though they stop there. I also factored key forwarding out of the ElectronDocument and into the superclass, depending upon the child conforming to CSKeyboardMachine.	2016-06-05 08:53:05 -04:00
Thomas Harte	363e14a92f	Reorganised system ROMs out of the Mac-specific folder, adjusted Mac code to expect to find them organised hierarchically (as how many os.roms am I going to have?) and added readme files to explain what's missing from the Git repository.	2016-06-05 08:33:01 -04:00
Thomas Harte	4c33517228	Added ROMs to the project and ensured they don't get uploaded.	2016-06-04 22:03:38 -04:00
Thomas Harte	b10a06e700	A CRT is still absent but this moves the ball back into the C++ side's court.	2016-06-04 22:00:50 -04:00
Thomas Harte	404873fe58	Started sketching out infrastructure for Vic-20 support.	2016-06-04 21:43:50 -04:00
Thomas Harte	d6e8cd676a	Trimmed and reordered just a little.	2016-06-04 16:02:16 -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	8538b62ea2	Made an attempt to extract and consolidate the logic behind the intermediate shaders.	2016-04-28 21:04:59 -04:00
Thomas Harte	496d979aca	Made a decision to clean up by creating per-shader classes. Well, more or less. First thing to be factored out: the output shader.	2016-04-27 22:29:54 -04:00
Thomas Harte	416c944f02	Experimental: let's try accumulating history directly in the framebuffer.	2016-04-26 21:41:39 -04:00
Thomas Harte	4ac1f959e9	A shortcut here and a shortcut there; this allows me at least to determine whether use of a PBO gains anything.	2016-03-19 17:07:05 -04:00
Thomas Harte	4cd0aa3416	Completed FIR filter based audio output.	2016-03-15 23:37:35 -04:00
Thomas Harte	7694297c83	Introduced an adapted version of the previous Clock Signal's FIR filter.	2016-03-15 21:05:20 -04:00
Thomas Harte	cfa616d593	Fixed: timing issue versus supplied test ROM was failure to include the Plus 1 ROM in the mix.	2016-03-12 11:51:20 -05:00
