b274d7008c Added precaution to make sure best-effort updaters aren't mid-update during document destruction. 2016-10-16 22:14:47 -04:00
Thomas Harte
61ad0f8bdc Fixed inverse characters, added an extra per-frame phase change, based on empirical observation, ensured header guard won't become ambiguous. 2016-10-16 22:14:01 -04:00
Thomas Harte
fae1bb0db9 First successful game loaded! It turns out exactly one '$' is correct. Probably. 2016-10-15 21:49:41 -04:00
Thomas Harte
a67afb7efa Switched to a tight crop on the pixel part of the display. 2016-10-15 21:43:46 -04:00
Thomas Harte
952a24f769 A quick hard-wiring of the OricTAP code to get the first file in a .tap correct, damn the rest, and I'm getting some on-screen feedback. Hooray! 2016-10-15 21:39:53 -04:00
Thomas Harte
a608bbebfb Performed enough wiring to put the onus back onto OricTAP to do appropriate things. 2016-10-15 21:32:59 -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
9730e8247f Ensured propagation of synchronise messages, added enough to do plain tone. Probably. So: noise and envelopes missing. And it's all far too quiet. 2016-10-15 21:04:21 -04:00
Thomas Harte
51bdac27ae Made some AY advances; it's now being polled for samples and collecting more information on what it needs to output. 2016-10-15 17:45:39 -04:00
Thomas Harte
da9c9ad51a Added in the missing keys; added variable phase to the video. 2016-10-14 22:39:27 -04:00
Thomas Harte
288d10c253 Got some keyboard reaction. 2016-10-14 21:44:15 -04:00
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

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

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

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

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
