Thomas Harte	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
Thomas Harte	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
Thomas Harte	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
