Thomas Harte	2ff157cf7a	Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.	2017-07-22 22:17:29 -04:00
Thomas Harte	3f609e17b3	Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups.	2017-07-21 21:18:51 -04:00
Thomas Harte	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
Thomas Harte	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	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
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	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	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	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	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	d335991e60	Shifted code out of the header.	2016-10-20 20:53:17 -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	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	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	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
