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

aff69dbc34 Resolved spurious static analyser issue; screen mode will always be 0–6 but it doesn't know that. Setting a non-zero divider doesn't feel worth worrying about for a cleaner compile. 2017-02-11 13:35:22 -05:00

f3d9aec8fc Fixed Electron's support for automatically booting floppy disks. 2017-01-08 14:47:41 -05:00
Thomas Harte
8cd1575891 Similar fix to that over in Oric land: ensure a known, effective initial value for the Plus 3's control register. 2016-12-28 18:52:36 -05:00
Thomas Harte
4fca30b81f Made the Plus 3 less chatty, documented invalidate_track. 2016-12-25 21:06:58 -05:00
Thomas Harte
3805e3d17d Ensured base address is set properly at construction. 2016-12-22 22:46:02 -05:00
Thomas Harte
63107cd492 Tidied, very slightly. 2016-12-15 19:49:25 -05:00
Thomas Harte
a555c5762a Rearranged code, hopefully into a more logical grouping. 2016-12-15 19:47:04 -05:00
Thomas Harte
4a7ddaf2e9 Added documentation and a quick note to self. 2016-12-15 19:43:04 -05:00
Thomas Harte
f61176cd7d Reinstituted something of the don't-do-pixel-work-until-an-affecting-write-occurs optimisation. 2016-12-15 19:20:14 -05:00
Thomas Harte
c1c70a767a Attempted fully to reinstate proper timing. 2016-12-15 18:52:16 -05:00
Thomas Harte
0326316bb8 Reinstated whole-frame counting. Thereby to reinstate proper interrupts. 2016-12-15 18:09:49 -05:00
Thomas Harte
b58b11fc93 Switched to a table-based dispatch of line-by-line actions, primarily to simplify. 2016-12-15 18:07:46 -05:00
Thomas Harte
fd541e1142 An early draft; dealing with the issue that not all cycles are necessarily consumed in a single call. Incomplete; broken. Committing for cross-machine visibility. 2016-12-12 08:01:10 -05:00
Thomas Harte
be7e05e109 Started attempting to move total responsibility for display-related interrupts and RAM timing into the video. 2016-12-11 18:34:49 -05:00
Thomas Harte
c5cf8d9531 Ensured the video subsystem correctly handles requests to run over a frame boundary. 2016-12-11 16:17:51 -05:00
Thomas Harte
52028432e1 Restored some semblance of output. 2016-12-10 22:19:10 -05:00
Thomas Harte
0aae1bd1ef Fixed calculation of termination cycle. 2016-12-10 21:35:41 -05:00
Thomas Harte
c43e481a33 Started factoring video out of the Electron. 2016-12-10 21:07:52 -05:00
Thomas Harte
a549fd1ecc Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron. 2016-12-10 13:42:34 -05:00
Thomas Harte
eb3a1fbfb7 Commuted remaining Electron underscores. It would be nice also to factor out the video, but the time hasn't come yet. 2016-12-03 13:01:01 -05:00
Thomas Harte
4fac538a57 Factored out the Electron's speaker and adjusted instance variable naming. 2016-12-03 12:41:02 -05:00
Thomas Harte
d1d93829cf Factored out the Tape and switched it to postfix underscores. 2016-12-03 12:18:08 -05:00
Thomas Harte
2003b514aa Switched the typer to postfix underscores. 2016-12-03 10:55:50 -05:00
Thomas Harte
2f459690d4 It would appear the 1770 and 1773 actually differ in relation to the (non-sensical) ability not to spin-up for a Type 2, and whether a side compare can occur. So the WD1770 class now requires a personality to be specified. Which it singly fails to honour. 2016-11-26 23:29:30 +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
311f8c0b47 Restored audio. 2016-11-16 11:10:07 +08:00
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
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
4a062c616f Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation. 2016-10-11 22:20:13 -04:00
Thomas Harte
de658b70d7 That's thread safety, subject to the async task queue being made to work... 2016-10-07 17:02:36 -04:00
Thomas Harte
2d26feb073 Added mappings for the previously-missing characters @, [ and ]. 2016-10-04 22:03:53 -04:00
Thomas Harte
f9ee6803df It's likely this should be set at startup too, based on latest info. 2016-10-03 22:16:10 -04:00
Thomas Harte
97304e22f0 Adjusted per tests on StarDot; it appears the tape interrupts may fire during audio output, as if in tape output mode. 2016-10-03 20:03:14 -04:00
Thomas Harte
dae6b45464 Ensured the always-on bit of the interrupt status register is indeed on. 2016-10-03 19:15:31 -04:00
Thomas Harte
79412dc84d Upped MFM clock cycles, switched back to using the typer for the ADFS and adjusted ADFS ROM slots. 2016-09-28 21:28:34 -04:00
Thomas Harte
4db086949a Made an attempt to add MFM decoding to the 1770; ensured something is returned when reading the Plus 3 status register again. 2016-09-25 21:38:52 -04:00
Thomas Harte
572d5587d9 Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register. 2016-09-25 21:24:16 -04:00
Thomas Harte
9bbcbd1001 Renamed class, intending to turn a Disk::Drive into literally just that, and have a thing with a PLL that consumes events be a Controller. 2016-09-25 20:05:56 -04:00
Thomas Harte
7f4c78139c Attempted to ensure that ADFS disks get to an appropriately-configured Electron. Not immediately sure why the shift press isn't working; doesn't need to be dealt with immediately. 2016-09-25 19:59:46 -04:00
Thomas Harte
6084020ab3 Added shift-break as a better way to boot suitable disks. Continued attempting to clean the 1770. 2016-09-25 14:11:22 -04:00
Thomas Harte
ce4100e5b9 Fixed slots for DFS and ADFS to sideways RAM; continued working on the 1770 to get as far as trying to get the body of a sector. 2016-09-24 22:04:54 -04:00
Thomas Harte
8db0030068 Fixed ROM loading by the Electron, turned the WD1770 into a 'disk drive' (it'll do for now), persuaded it to get all the way through a very specifically convenient type 1 command. 2016-09-20 22:14:33 -04:00
Thomas Harte
3b97b038b9 Corrected and sketched out state machine far enough to get to a complaint about unhandled work. 2016-09-20 15:56:31 -04:00
Thomas Harte
e358057440 Added a WD1770 run_for_cycles call. So I really can now move that as far as reporting that it has no disk? 2016-09-20 07:42:17 -04:00
Thomas Harte
cd5939501f Treading water some more, ensured the DFS and ADFS ROMs get to the Electron. It now even inserts the DFS ROM if it has a DFS disk image. Might need to make it a sideways RAM though? Regardless, the next job surely — surely! — has to be to stop avoiding the 1770? 2016-09-20 07:36:57 -04:00
