Thomas Harte	3dbb602419	This seems to be a bit more likely.	2016-10-14 21:36:59 -04:00
Thomas Harte	138eabcff4	Continued in my effort to wire up a keyboard. Will need further to continue.	2016-10-14 21:35:15 -04:00
Thomas Harte	d8e4c488c2	Started iterating towards having an AY and a fully-working keyboard.	2016-10-14 21:18:03 -04:00
Thomas Harte	8867ad647c	Made an attempt at implementing the loopbacks necessary for diagnostics.	2016-10-13 21:47:12 -04:00
Thomas Harte	41e7eff6c8	Added a VIA. Now it's time to find out how poor my 6522 emulation is.	2016-10-13 20:50:55 -04:00
Thomas Harte	c9962f6502	Made an almost complete implementation of video. Just one row of the diagnostics cartridge seems to be off, showing thw wrong character set.	2016-10-13 19:34:29 -04:00
Thomas Harte	0ca383ecd1	Set every single key to be NMI, in order to be able to progress with the diagnostics cartridge.	2016-10-13 18:56:55 -04:00
Thomas Harte	69920a4979	Made some basic first attempt at parsing video attributes; ensured lowest byte of ROM is readable.	2016-10-13 07:59:11 -04:00
Thomas Harte	ae48ad1bb4	Meaningful text! Albeit with the initial 'O' of 'Oric' missing. I guess control codes and NMIs next?	2016-10-12 22:03:54 -04:00
Thomas Harte	120b2d9e33	Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from.	2016-10-12 21:52:47 -04:00
Thomas Harte	1f857c619b	Fixed timing issues. Static box of frame achieved!	2016-10-12 21:42:36 -04:00
Thomas Harte	304f0999cd	Made a faulty but hopefully creditable attempt to demarcate an Oric frame.	2016-10-12 21:29:21 -04:00
Thomas Harte	8c8a71107e	Added just enough wiring to add something that will generate the video, one day.	2016-10-12 19:20:23 -04:00
Thomas Harte	e6937d8003	Ensured that the ROM gets installed. So next for some video action?	2016-10-12 18:51:02 -04:00
Thomas Harte	f7d2e988b6	Mildly enhanced unit test, while I'm curious.	2016-10-11 22:22:53 -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	cbc3d28217	Ensured an exception is thrown if no machine to run a file is found. E.g. right now if you tried to open a ZX Spectrum .tap.	2016-10-11 21:03:01 -04:00
Thomas Harte	4f78d693e9	Reintroduced gap as a string of 1s, made an attempt to look up bit ordering. Still unclear on high/low versus low/high.	2016-10-11 08:07:51 -04:00
Thomas Harte	70f004efbb	This may be feeding bits in the wrong direction or calculting the wrong parity or doing something else amiss but should now be correct as to bytes.	2016-10-11 07:57:10 -04:00
Thomas Harte	df01c78039	It's a bit of a mess but this is probably close to appropriate for Oric TAP files.	2016-10-11 07:39:48 -04:00
Thomas Harte	00e3ad9b04	Added a bit more ceiling for lowpass filtering on constrained machines.	2016-10-10 07:51:01 -04:00
Thomas Harte	95afdbe966	Merge pull request #56 from TomHarte/NoBuffer ... Removes the locking attempt at enforcing a circular audio buffer on the Mac	2016-10-10 07:49:13 -04:00
Thomas Harte	02bfa8b8de	This should just trust.	2016-10-10 07:45:09 -04:00
Thomas Harte	f4b39c4435	Added documentation and experimentally reduced packet size. We'll see.	2016-10-10 07:42:24 -04:00
Thomas Harte	de397799ed	Pulled away my crazy rationalisation of an audio queue into a circular buffer and decided just to trust the OS. This should reduce latency.	2016-10-10 07:30:00 -04:00
Thomas Harte	c284818af5	Fixed alphabetisation of project.	2016-10-07 17:21:02 -04:00
Thomas Harte	cffdbc7c00	Merge pull request #55 from TomHarte/AsyncQueue ... Introduces an asynchronous task queue	2016-10-07 17:20:35 -04:00
Thomas Harte	4829b896f7	Documented the async task queue.	2016-10-07 17:18:46 -04:00
Thomas Harte	922dd6a586	Hit up the other two kinds of audio generator.	2016-10-07 17:10:00 -04:00
Thomas Harte	002e923cf1	Added shutdown logic.	2016-10-07 17:08:29 -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	e53455a936	Not having read the C++ synchronisation primitives before, this async task queue is probably incorrect. But nevertheless, let's have a quick go at employing it — in a hideously thread unsafe fashion — for audio generation. What can possibly go wrong?	2016-10-07 16:56:34 -04:00
Thomas Harte	2d26feb073	Added mappings for the previously-missing characters @, [ and ].	2016-10-04 22:03:53 -04:00
Thomas Harte	ebef5ccdba	Merge pull request #54 from TomHarte/BCDTest ... Installs hoglet's BCDTest as a formal part of the test suite	2016-10-04 07:53:39 -04:00
Thomas Harte	c097886d00	Installed hoglet's BCDTest as a formal part of the test suite; removed some redundant semicolons in the Wolfgang Lorenz tests while I was here.	2016-10-04 07:52:44 -04:00
Thomas Harte	f9ee6803df	It's likely this should be set at startup too, based on latest info.	2016-10-03 22:16:10 -04:00
Thomas Harte	f1af6ef8b6	Merge pull request #53 from TomHarte/BCDTest ... Resolves failure of the jsbeeb BCDTest.ssd	2016-10-03 22:07:20 -04:00
Thomas Harte	fa7c64bb5d	Eventually reached an implementation of ADC that continues to satisfy all the formalised unit tests while also satisfying the manual BCDTest, that I need to find a way to formalise. I fixed the unit tests for Swift 3 while here, and attempted to do some unrelated NIB stuff with no real success.	2016-10-03 22:03:39 -04:00
Thomas Harte	97304e22f0	Adjusted per tests on StarDot; it appears the tape interrupts may fire during audio output, as if in tape output mode.	2016-10-03 20:03:14 -04:00
Thomas Harte	dae6b45464	Ensured the always-on bit of the interrupt status register is indeed on.	2016-10-03 19:15:31 -04:00
Thomas Harte	6ecd8aac61	Merge pull request #52 from TomHarte/SingleDocument ... Collapses Mac binding down to a single NSDocument	2016-10-03 08:02:30 -04:00
Thomas Harte	cfdd5fb686	By removing its status as a special case, eliminated the Atari 2600 document. It's fairly clear that my date with doing joysticks properly can be deferred only so much longer but this is no worse than previously things were.	2016-10-03 08:01:04 -04:00
Thomas Harte	bf468db73d	Migrated the Vic document to a mere options panel.	2016-10-03 07:42:05 -04:00
Thomas Harte	9e6e84647e	Quick formatting fix.	2016-10-02 22:06:28 -04:00
Thomas Harte	f28881ec6b	... and with the return of stored options and the shift of the aspect ratio to somewhere else (to sit, temporarily), the Electron document is the first of the gang to die.	2016-10-02 22:04:47 -04:00
Thomas Harte	19457621d8	Redistributed ownership of the user defaults key prefix, the Electron now works other than that settings aren't retained.	2016-10-02 21:56:50 -04:00
Thomas Harte	f1b99263e0	Relocated responsibility for loading ROMs, giving an Electron that 'works' (i.e. options aside) again.	2016-10-02 20:39:06 -04:00
Thomas Harte	989a1581da	Migrated analysis logic from the document controller to the document.	2016-10-02 17:04:14 -04:00
Thomas Harte	0c75c2fc41	Disabled all machine-specific document code, to force the migration of functionality. The 2600 works other than the little matter of input.	2016-10-02 16:57:57 -04:00
Thomas Harte	6c6e9830dd	Started factoring the options panels out, in the hope that they'll become the only machine-specific thing. At least in the short term.	2016-10-02 16:31:50 -04:00
