90856a0e7a Adds mixdown/up capability to Speaker. 
To deal with occasions when the host machine just always is either mono or stereo, and the emulated machine must cope.
 2020-02-16 13:50:18 -05:00
Thomas Harte
e02d109864 Nudges the LowpassSpeaker towards supporting stereo generation. 2020-02-15 18:03:12 -05:00
Thomas Harte
49b8e771b5 Adds the messaging that would allow a Speaker to output stereo, semantically. 2020-02-15 13:40:19 -05:00

c26c8992ae Reintroduces joystick support; eliminates CSBestEffortUpdater. 2020-02-08 21:27:04 -05:00
Thomas Harte
b76a5870b3 Moves drawing into the next timer tick after retrace if sync locked. 
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.

This should completely eliminate tearing for machines that can be synced to the native output rate.
 2020-02-08 18:07:13 -05:00
Thomas Harte
7c0f3bb237 Gets to slightly adjusting execution speed and matching up respective vertical syncs. 
I probably still need to move the ->draw inline.

085529ed72 Makes the shifter behaviour conform to its documentation. 2020-02-02 17:26:39 -05:00

Thomas Harte
b514756272 Adds the option to run machines at a multiple of their real speeds.

3f57020b00 Resolves thread safety oversights in SDK kiosk mode. 2020-01-25 14:48:00 -05:00
Thomas Harte
d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.
 2020-01-20 21:45:10 -05:00
Thomas Harte
4de121142b Adds a flags parameter to the BestEffortUpdater delegate. 
On the Cocoa side, cuts Swift out of the update loop, as that seems merely to add code.
 2020-01-20 16:21:53 -05:00
Thomas Harte
3c760e585a Switches to accepting a bit mask of events to run_until. 2020-01-20 16:08:21 -05:00

1b4b6b0aee Renames: NumberTheory -> Numeric. 2020-01-19 23:14:35 -05:00
Thomas Harte
5391a699a4 Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation. 
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.

91fae86e73 Factors out paging, implements a bit more of the BD500.

 2020-01-15 23:15:39 -05:00
Thomas Harte

Thomas Harte
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
Thomas Harte
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

 2019-12-28 22:50:34 -05:00

a9d1f5d925 Pulls out address reload as something I can position independently.

7ff4594f09 Eliminates fast loading Objective-C/Swift protocol. 
A very long time ago, when each machine had its own Objective-C class, this protocol was used to indicate which machines support that feature. It no longer communicates anything.

Thomas Harte
f28c124039 Adds a route to divert key events before they reach Cocoa. 
If you were to use this, it would have the effect of disabling in-app keyboard short-cuts in favour of routing keys to the emulated machine.

8a14f5d814 Updates to Xcode11 recommended project settings. 
The updated compiler also flagged a potential issue with CPU::Z80::Register not being a namespace re: 'Refresh' versus CPU::Z80::PartialMachineCycle. I don't entirely see it, but this fixes the problem.

I also finally figured out what the compiler was trying to tell me about ROMRequester.xib.

8de6cd3f44 Ensures that ROM files can be dragged and dropped into Swift.

9b9831f28b The Mac port will now at least display a list of missing ROMs.

 2019-06-01 19:31:32 -04:00
Thomas Harte
6d985866ee All proper inputs are now provided to the audio generator. 
Hopefully. The next job is to generate audio. If that sounds correct, then the disk motor speed question can be tackled.
 2019-06-01 15:03:15 -04:00
Thomas Harte
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.
