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

e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00

580f347727 Fixed Oric SCART mode by having it change what it's giving to the CRT based on which shader it knows will be active. 2016-12-10 13:55:56 -05:00
Thomas Harte
6cdd41e5a9 Added direct use of the colour ROM, uploading 16 bits per pixel to contain the entire ROM composite wave. 2016-12-09 22:17:10 -05:00
Thomas Harte
2003b514aa Switched the typer to postfix underscores. 2016-12-03 10:55:50 -05:00
Thomas Harte
82899f2f47 Ensured flag setting is atomic, removed duplication of interrupt request versus busy, found better names for the personality testers, unified delegate protocol. 2016-12-01 07:41:52 -05:00

73d30b9c00 Corrected typo. 2016-11-25 21:30:45 +08:00
Thomas Harte
12956901d6 Filled in some register mirrors. 2016-11-25 21:28:11 +08:00

8be81f6ebd Supplied disks are given to the Microdisc. 2016-11-25 20:53:38 +08:00
Thomas Harte
4af678d2ed Gave the Microdisc a clock signal, added just enough of force interrupt to avoid a spurious belief that a type 3 command has started. 2016-11-25 20:51:39 +08:00
Thomas Harte
5be45c6c50 Ensured proper default behaviour. 2016-11-25 20:30:27 +08:00
Thomas Harte
d33f3b9224 This is the broad strokes effort at enabling Microdisc emulation. 2016-11-25 20:15:48 +08:00
Thomas Harte
707763f80b Added Microdisc storage to the Oric class, switching all instance storage to postfix underscore while I'm here. 2016-11-22 22:22:00 +08:00
Thomas Harte
ea33a28695 Any Oric-format disks that are inserted now make it all the way to the Oric, along with a request to emulate the Microdisc. It has received a copy of the ROM. The ball is entirely in its court now. 2016-11-21 20:59:25 +08:00

8b40ae03ca Extended analysis to spot IRQ and NMI vector changes, for titles that simply adjust those then exit. Ensured Oric emulator can type and load quickly on an Oric 1 just as well as on an Atmos. 2016-11-15 11:05:53 +08:00
Thomas Harte
e2cdfae8a7 The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation. 2016-11-15 10:39:16 +08:00
Thomas Harte
9c550c594a Moved audio work back into its own thread, but this time it queues up an all happens only upon a flush. Hopefully to resolve synchronisation cost concerns. 2016-11-09 21:17:50 -05:00
Thomas Harte
64827931bf Switched the Oric implementation simply to rely upon the Storage-level tape parser. So now there's only one, authoritative one of those. 2016-11-07 21:57:58 -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
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
626e719fab Added sanity checks on loading quickly. 2016-11-03 22:50:49 -04:00
Thomas Harte
a7e4c0c3b5 Switched to a ROM trap for typing. 2016-11-03 22:21:05 -04:00
Thomas Harte
8c70dc5891 Implemented typer for the Oric, and I'm starting to think the code is a bit too repetitious. Refactoring will be forthcoming. Added CLOAD"" as the loading command for all Oric software. 2016-11-03 22:14:40 -04:00
Thomas Harte
9c2df231ce Made fast loading optional. 2016-11-03 07:59:30 -04:00
Thomas Harte
e9f1a6a79d This appears to be it. The secret? Don't worry about the stop bits. They're just processing time. Latch onto the next start. 2016-11-03 07:34:48 -04:00
Thomas Harte
827a919368 This is an initial attempt at reading actual tape data. It loses sync though. 2016-11-02 22:30:53 -04:00
Thomas Harte
419629ee6e Completed proof of theory for fast loading. It's just an around-the-back direct-to-file hack for now though. 2016-11-02 21:09:49 -04:00
Thomas Harte
bb58caff52 Merge branch 'master' into FastOricTape 2016-10-31 22:11:03 -04:00
Thomas Harte
21604376e6 Reintroduced clocking of the AY and boxed in the range of the master divider a little further. 2016-10-30 22:51:08 -04:00
Thomas Harte
33512988fb Added a basic cycle skipper plus some notes. 2016-10-30 22:39:47 -04:00
Thomas Harte
4fab794747 Added a direct-to-two-cycles emulation path for 6522 owners. 2016-10-27 21:13:25 -04:00
Thomas Harte
44910d90ba Adjusted aberrations in semicolons. 2016-10-20 21:20:13 -04:00
Thomas Harte
d335991e60 Shifted code out of the header. 2016-10-20 20:53:17 -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
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
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
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
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
