40339a12e1 Formalised the use of a cycles count with a divider, bringing a few additional plain-int users into the fold. 2017-07-25 07:15:31 -04:00
Thomas Harte
90bf6565d0 Reduced int/Cycle conversions in the Electron and on the Atari 2600, where the current framework makes it possible to do so. 2017-07-24 22:53:13 -04:00

a6e377aa57 The Electron's video is now a ClockReceiver. 2017-07-24 22:36:42 -04:00
Thomas Harte
915f587ef1 Updated the Electron's tape class to be a ClockReceiver. 2017-07-24 21:36:30 -04:00
Thomas Harte
b7f88e8f61 Filter is now a ClockReciever, affecting all sound output devices. 2017-07-24 21:29:13 -04:00
Thomas Harte
8a2bdb8d22 Converted the TimedEventLoop and the things that sit atop it into ClockReceivers. 2017-07-24 21:19:05 -04:00
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
83628b285b Experimentally turned the 6502 into a clock receiver. No problem encountered. 2017-07-22 21:52:21 -04:00
Thomas Harte
dddb30477b Used a different inner-loop variable, for clarity. 2017-07-21 21:52:08 -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

b3861ff755 Reduced copying of Pulses. 2017-07-16 19:49:31 -04:00
Thomas Harte
1d3ae31755 Abstracted the concept of an Acorn shifter away from being a PLLParser. The Acorn tape parser now skips using that class and uses the shifter. The actual Electron also uses the shifter. So the two are completely aligned. Net result: the Electron should successfully load exactly when static analysis was successful. 2017-07-16 19:24:01 -04:00

481487f084 Oh yuck, it looks like I've repeated this same test in two different places. Must figure out where to factor it out to. But in the meantime, the emulated Electron has just loaded its first CSW. 2017-07-13 22:39:30 -04:00
Thomas Harte
353c854734 Removed a TODO that is no longer appropriate. 2017-07-09 22:06:50 -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
e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00
Thomas Harte
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
Thomas Harte
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
