Transfers possession of keyboard mappings from the Mac side over to individual machines.

Thomas Harte
96648df5fe
Ensures all parts of the Electron have a fully-defined initial state.
...
Specifically to resolve an error with shift being pressed at startup due to a failure to establish a default value for that flag, but applying the same principle across the board.
2017-08-31 22:29:24 -04:00
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.
2017-08-21 21:56:42 -04:00
Thomas Harte
f68565a33f
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.
2017-08-17 10:48:29 -04:00
Thomas Harte

2017-08-16 11:56:52 -04:00
Thomas Harte
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
296c7cec05
Adopted flush widely.
2017-07-25 20:42:51 -04:00
Thomas Harte
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.

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.

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
be7e05e109

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.

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.

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
