Thomas Harte
ee71be0e7e
Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.

Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.

bbb17acf3a
Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.
2017-08-03 11:50:50 -04:00
Thomas Harte
ad3a98387f
Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.
2017-08-03 11:42:31 -04:00
Thomas Harte
968d2bb8ba
Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.
2017-07-27 21:53:45 -04:00
Thomas Harte
9ef232157b
Revoked the operator bool() on WrappedInt as providing an indirect means for implicit but incorrect assignment to unwrapped ints. Got explicit about run_for intention and simplified HalfClockReceiver slightly by building a lossy and a flushing conversion to Cycles into HalfCycles. Adapted the all-RAM Z80 properly to return HalfCycles.
2017-07-27 21:38:50 -04:00
Thomas Harte
cda223ffc0
Added explicit signedness cast.
2017-07-25 22:49:03 -04:00
Thomas Harte
279c369a1f
Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation.
2017-07-25 22:21:09 -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.

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

2016-12-15 19:20:14 -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

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

Commuted remaining Electron underscores. It would be nice also to factor out the video, but the time hasn't come yet.

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
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
Thomas Harte
a9e65e9b7a
Tweaked disk side density, added call-outs to a WD1770 if the Electron had one (albeit without run_for_cycles yet as I need to figure out the clock rate), added a shell of the basic functions of the WD1770. No implementation yet.
2016-09-19 22:06:56 -04:00
Thomas Harte
21e5f407d8
I need to get a bit more definitive on naming but this gets all the way to setting a configuration upon an Electron.
2016-08-31 22:03:42 -04:00
Thomas Harte
c0402d0c2b
Gave tapes their own namespace.
2016-08-27 17:09:45 -04:00
Thomas Harte
d9016909ed
Added some wiring for PAL/NTSC mode switching on the Vic, making an attempt to simplify the whole loop of having different clock rates.
2016-08-14 13:33:20 -04:00
Thomas Harte
5d40d70c92
Fixed 6560 addressing error, added an autotyper for Vic disks (more work potentially needed), fixed semantics for testing whether a 6502 is about to reset.
2016-08-01 10:32:32 -04:00
Thomas Harte
2332f72875
Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more.
...
(obiter: the 1540 now appears to discern the correct sequence of bits. Framing is off in my test printfs but that's neither here nor there).
2016-07-31 13:32:30 -04:00
