1972ca00a4
Fixes quick-NTSC-avoidance fix.
...
I suspect this is very temporary, but here it is.
2020-01-16 00:01:16 -05:00
93cecf0882
Ensures no possible initial NTSC, removes printfs.
2020-01-15 23:47:45 -05:00
aac3d27c10
Adds activity indicators for the BD-500 and Jasmin.
...
Also slightly cleans up DiskController a little further.
2020-01-15 23:39:15 -05:00
91fae86e73
Factors out paging, implements a bit more of the BD500.
...
That is, enough seemingly fully to work, if I force the drive to report ready.
2020-01-15 23:15:39 -05:00
f258fc2971
Adds enough of a BD500 for the boot sector seemingly to load.
2020-01-14 23:15:27 -05:00
6b84ae3095
Makes the Microdisc also a DiskController, and simplifies delegate interface.
2020-01-14 22:53:27 -05:00
5dd8c677f1
Factors out from the Jasmin the stuff that I'm going to need to repeat for the BD-500.
2020-01-14 22:23:00 -05:00
3ced31043a
Makes Jasmin autoboot optional, adds a Jasmin reset key, adds the Jasmin to File -> New... .
...
Also finally implements KeyNMI.
2020-01-05 21:57:33 -05:00
7361e7ec34
Fixed: the issue was failing to propagate motor control.
...
Also it seems to be incorrect to have the Jasmin paged at initial boot.
2020-01-05 21:35:20 -05:00
533729638c
It seems like Jasmin paged in at boot, and button = page back in and reset works?
...
At least, that gets me a 'boot failed' error. Which is something.
2020-01-05 20:34:15 -05:00
9f30be1c13
Attempts to implement most of a Jasmin disk interface.
...
With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.
2020-01-05 20:05:55 -05:00
c1bae49a92
Standardises on read and write for bus accesses.
...
Logic being: name these things for the bus action they model, not the effect they have.
2020-01-05 13:40:02 -05:00
0dae608da5
Embraces std::make_[unique/shared] in place of .reset(new .
2019-12-23 21:31:46 -05:00
5456a4a39d
Eliminates static where constexpra aren't class members; adds some if constexprs for clarity.
2019-12-22 13:42:24 -05:00
d85ae21b2f
Adds an explicit declaration of chip type to all AY users.
2019-12-18 19:28:41 -05:00
5149f290d0
Starts trying to formalise just-in-time execution.
...
Which, at least, simplifies Cycle/HalfCycle to Cycle run_for usage via template.

2019-07-19 22:35:22 -04:00
723137c0d4
With some time additions to the 6522, starts wiring in Macintosh audio.
...
The audio buffer is also the disk motor buffer, so this is preparatory to further disk work.
2019-06-01 14:39:40 -04:00
21908dfcef
Restores Oric audio.
2019-02-05 21:43:07 -05:00

Wires through set_display_type.
2018-11-29 20:44:21 -08:00
a25470ee41
Permits tweaking of PhaseLinkedLuminance8 sampling offset.
2018-11-29 16:29:28 -08:00
fd579a019b
Introduces a new scan source data type, motivated by the reasoning used by the Oric.
...
Specifically: it'll allow PCM sampling of the potentially arbitrary composite generation logic of various machines.
2018-11-28 20:40:22 -08:00
5f90941e4e
Starts nudging the Oric back to functionality under the new regime.
...
i.e. one where it can't invent internal pixel formats.
2018-11-28 18:16:13 -08:00
64465f97b6
Starts towards reintroducing the proper mechanisms for selecting a display type at runtime.
2018-11-28 17:53:33 -08:00
8a699b6072
Kills setup_output definitively, saving some indirection. set_scan_target takes its place.
2018-11-14 21:52:57 -05:00
b40211d2c0
Starts to bend 'CRTMachine' to a world farther from owning the GPU relationship.
2018-11-03 21:54:25 -04:00
a8645f80bf
Introduces 'non-exclusive' emulator-space keyboards.
...
i.e. sets of keys that don't amount to an entire keyboard in the modern sense. Experimentally used by the Master System for its reset key.
2018-10-24 21:59:30 -04:00
be01203cc1
Starts to expand the range of supported 6502s.
...
This fully implements the NES 6502 because, well, it's virtually no extra work, and ensures that RDY takes effect on write cycles on 65C02s.
2018-08-13 22:17:22 -04:00
76a73c835c
Forces 6502 consumers to declare which model — the original, 65C02 or 65SC02.
...
All present machines use a regular 6502.
2018-08-06 20:06:07 -04:00
7e58a44771
Renames ConfigurationTarget to MediaTarget as per its newly-reduced interface.
2018-07-10 21:32:28 -04:00
3862fdb44c
Simplifies initialisation procedure for all machines.
...
With the side effect of allowing every machine to try to load only the ROMs that it needs.
2018-07-10 20:00:46 -04:00
6812a001d8
Teaches the Oric to apply a lighter Disk II touch when possible.
2018-05-28 18:20:43 -04:00
928aab13dc
Introduces more granular clocking announcements to the Disk II.
...
As well as making it accept the clock rate it'll actually receive, to supply to the drives, so that they spin at the proper speed.
2018-05-28 17:19:29 -04:00
db8d8d8404
Commutes Sleeper to ClockingHint::Source, making state more granular.

7c3dd55e5c
Corrects typo and improves exposition.
2018-05-24 18:57:35 -04:00

Corrects meaning of the Microdisc's paging control.
2018-05-24 18:53:02 -04:00
e482929da8
Enhances the Disk II's ability to sleep.
...
Also enables Disk II sleep observation in the Oric.
2018-05-19 23:15:28 -04:00
7b7beb13a3
Eliminates the fiction of setting and getting registers.
...
The Disk II seems lower level than that; it will read the data bus whenever it likes, it is the programmer's responsibility to keep up with that. It also reserves the right not to load the bus regardless of whether it receives a read or write access.
2018-05-17 21:39:11 -04:00
5d6b5d9f10
Eliminates all emdashes in cross-platform code.
2018-05-13 15:34:31 -04:00

2018-05-13 15:19:52 -04:00
2252c29495
Switches the Oric to string insertion at the time of consumption.
...
To avoid issues around keyboard scanning being decoupled from consumption via IRQ, but not buffered. Keys pressed while BASIC is otherwise busy are just lost.
2018-05-13 14:02:46 -04:00
39c0bc6c47
Factors string serialisation with \n\r conversion out of the Apple II and reuses it with the Oric.

Makes the Oric an event source.
2018-05-11 23:05:36 -04:00
