d335991e60 Shifted code out of the header. 2016-10-20 20:53:17 -04:00
Thomas Harte
9c956f83b8 Made it slightly more clear that the correct test is conformed to. 2016-10-20 19:23:36 -04:00
Thomas Harte
21cfb39ed9 Added 60Hz output support. 2016-10-20 07:34:23 -04:00
Thomas Harte
5c69728625 Introduced a memory fuzzer, and ensured the Oric uses it. 2016-10-19 21:31:50 -04:00
Thomas Harte
734b575d30 Ensured no attempt to write to pixel storage if none was available. 2016-10-19 21:17:27 -04:00
Thomas Harte
ca28e3c64e Ensured the AY is pumped linearly, not exponentially. 2016-10-18 22:21:06 -04:00
Thomas Harte
9669a5ec9b Switched to a more authentic interfacing to the AY. 2016-10-18 19:32:15 -04:00
Thomas Harte
988bbb5ab1 Ensured AY registers aren't rewritten just because of a synchronise event. A stall prior to figuring out proper bus logic, clearly. 2016-10-17 08:05:57 -04:00
Thomas Harte
1a57e89ff0 Altered phase so that it now merely accounts for accumulated error across a frame. Can probably do better. 2016-10-17 08:04:15 -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
a67afb7efa Switched to a tight crop on the pixel part of the display. 2016-10-15 21:43:46 -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
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
4a062c616f Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation. 2016-10-11 22:20:13 -04:00
