e9d6566e9c Of course, changing the IRQ enable may immediately change the IRQ line. Signal if so. 2016-11-26 09:35:44 +08:00

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
Thomas Harte
54246c8f1a Interrupt enabling works the other way around I think, and both registers with only one bit defined should probably return '1' in all other places? 2016-11-25 21:24:59 +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

5c019ad1c0 Okay, so it looks like both ROM paging flags are the opposite of what I previously had. 2016-11-25 20:42:40 +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
7c2d9f3752 This seems to be right, per http://wiki.defence-force.org/doku.php?id=oric:hardware:floppy_disk_controller_wd1793 2016-11-22 22:35:43 +08:00

5ebc1c63ff Switched video to postfix underscores, for consistency. 2016-11-22 22:28:45 +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
0c3644f350 Made a second parse at logic. We'll see. 2016-11-22 22:12:32 +08:00
Thomas Harte
03843bf934 Unified delegates. Let's keep it easy for the caller. 2016-11-22 22:11:11 +08:00
Thomas Harte
13a608a8c2 Added what may be correct paging logic. 2016-11-22 22:09:52 +08:00
Thomas Harte
363db695e8 Started implementation of the Microdisc selection logic. 2016-11-22 08:12:53 +08:00
Thomas Harte
09f965e6a9 Fixed potential bug whereby inserting a disk into a drive that hadn't been lazily allocated yet but had already been selected wouldn't take effect. 2016-11-22 08:11:57 +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

311f8c0b47 Restored audio. 2016-11-16 11:10:07 +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
338904fffe Made similar cleanings of the Electron and Vic. 2016-11-05 15:07:57 -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

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

b04ba41951 Moved code out of header. 2016-10-30 20:16:58 -04:00

3b52ab0d37 Cut some dead state. 2016-10-30 20:16:52 -04:00
Thomas Harte
58f888c6ad Limited CRT calls. 2016-10-30 16:21:20 -04:00
Thomas Harte
1ff9b474bf Made an attempt to make execution flow through this loop more straightforward for a branch predictor. 2016-10-30 15:30:39 -04:00
Thomas Harte
7843a244b0 Ensured emulation doesn't enter an infinite loop if the user attempts to read beyond the end of a tape. 2016-10-28 22:23:25 -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
2eda0b3c86 Attempted to simplify the logic behind the most common 6522 usage. 2016-10-27 21:06:31 -04:00
Thomas Harte
30d4a7c662 Fixed: blinking means ink vanishing and appearing. Nothing else. 2016-10-24 21:58:15 -04:00
Thomas Harte
09687a2e2f Removed errant newline. 2016-10-20 21:30:12 -04:00
Thomas Harte
44910d90ba Adjusted aberrations in semicolons. 2016-10-20 21:20:13 -04:00
Thomas Harte
6292ac5b26 Yet more .hpp clean(s)ing. 2016-10-20 21:15:21 -04:00
Thomas Harte
c5948ef177 Evicted more header-resident code. 2016-10-20 21:05:32 -04:00
Thomas Harte
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
