394ee61c78 Starts a switch to reflectable-style runtime options. 
The Amstrad CPC and ZX80/81 have made the jump so far, subject to caveats. The macOS build is unlikely currently to work properly.

Thomas Harte
05bcd73f82 Attempts to pull drive ownership into DiskController. 
For the sake of being more intelligent as to drive clocking, hopefully. And, eventually, to support multiple drive selection.

Temporarily breaks ST video in the endeavour.
 2020-01-29 22:18:41 -05:00
Thomas Harte
0e29c6b0ab On further reflection, I think events should occur after the running period. 
I'm testing this now for sanity in 2/4bpp mode.
 2020-01-28 23:26:37 -05:00

Thomas Harte
03d23aad41 Corrects reported ZX80/81 scan status. 2020-01-25 23:27:09 -05:00
Thomas Harte
294e09f275 All these 'override's can be 'final's. 
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.
 2020-01-23 22:57:51 -05:00
Thomas Harte
ba516387ba In all these instances, final => override. So no need to repeat myself. 2020-01-23 22:35:39 -05:00
Thomas Harte

Thomas Harte
8404409c0d Causes the Atari 2600 to obey normal flush semantics. 
This stuff is going to become more important with run_until.
 2020-01-22 22:05:51 -05:00
Thomas Harte
a71c5946f0 Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine. 
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.
 2020-01-21 22:28:25 -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
3c760e585a Switches to accepting a bit mask of events to run_until. 2020-01-20 16:08:21 -05:00
Thomas Harte
cb61e84868 Starts building out higher-level run_until functionality. 
Specifically: you can now run until the next set of speaker samples has been delivered.
 2020-01-20 12:12:23 -05:00
Thomas Harte
8349005c4b Adds CRTMachine::run_until, which will run until a condition is true. 
I want to get to being able to say "run until the beam is 60% of the way down", "run until a new packet of audio has been delivered", etc.
 2020-01-19 23:52:47 -05:00

d30f83871d Corrects Jasmin activity light. 2020-01-16 22:59:43 -05:00
Thomas Harte
efd684dc56 Opts the BD-500 in for modified Shugart RDY. 
Hopefully this is correct. I'm presently mystified as to other options.
 2020-01-16 21:34:57 -05:00
Thomas Harte
1972ca00a4 Fixes quick-NTSC-avoidance fix.

Thomas Harte
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
Thomas Harte
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
Thomas Harte
f5c194386c Ties head load to ready. 
BD-DOS no longer perpetually retries.
 2020-01-14 23:45:36 -05:00
Thomas Harte
62c3720c97 Adds status register and shout-outs on other address access. 2020-01-14 23:24:11 -05:00
Thomas Harte
f258fc2971 Adds enough of a BD500 for the boot sector seemingly to load. 2020-01-14 23:15:27 -05:00
Thomas Harte
6b84ae3095 Makes the Microdisc also a DiskController, and simplifies delegate interface. 2020-01-14 22:53:27 -05:00
Thomas Harte
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
Thomas Harte
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
Thomas Harte
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
Thomas Harte
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
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
Thomas Harte
e4349f5e05 Slightly clarifies logic. 2020-01-04 21:32:34 -05:00

Thomas Harte
19ddfae6d6 Adds Joystick key code mode, ensures events aren't posted in interrogation mode. 
This should fix Turrican due to the latter change; I'm not aware of software that uses the former.
 2020-01-04 09:45:59 -05:00

Thomas Harte
42ccf48966 Judging by Pompey Pirates Menu 88, vsync should occur a line earlier, ending during line 0. 2020-01-02 20:16:28 -05:00

a99ebda513 Takes a first shot at (inverted) Mac video output. 2019-05-04 22:27:58 -04:00
Thomas Harte
537b604fc9 It looks like writes should always go to RAM. 
Now I see the screen buffer being filled with `0xffff`s, along with what is probably disk motor control data.
 2019-05-04 17:29:30 -04:00

 2019-05-03 23:40:22 -04:00
Thomas Harte
68392ce6f5 Adds enough of a concept of Mac video to get a properly initialised display. 
Completely empty at present, naturally. Also this is the very first time I've run my 68000 at live speed. From just one data point, it's not terrible. Phew!

c7c21a7e2c Sorry, ColecoVision, it's composite only for you. 2019-02-24 22:37:24 -05:00
Thomas Harte
16731661e8 Switches back to being explicit about the colour burst phase. 
Some sort of phase inversion otherwise seems to be achievable by software that switch modes often.
 2019-02-24 22:28:11 -05:00
Thomas Harte
d4134cd0d8 Restores proper colour phase to the Apple II. 
Given that its timing errors were fixed, this also switches back to using 'default' colour bursts — i.e. ones with implicit phase. The Apple II continues to be an excellent bellwether for issues in the pipeline, and this helps further to ensure that.

Thomas Harte
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

Thomas Harte
da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT.

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

Thomas Harte
2e4c4c3e91 Makes some attempt to implement paging. 
This causes several of the 32kb games to be recognised by the BIOS and permitted to start, so it really really may be time to stop deferring work on the VDP.
 2018-09-24 21:34:42 -04:00

Thomas Harte
5b9e7213dd Adds a couple of joystick inputs. 
SG1000 titles all seem to work now.
 2018-09-23 21:55:07 -04:00
Thomas Harte
2253341904 This now goes far enough for the only SG1000 game I'm testing to start up. 
Which hopefully gives me as much as I need to implement joypads, etc, and definitively get to just the VDP being outstanding.
 2018-09-23 17:42:42 -04:00

Thomas Harte
0d01346ad4 Advertises SMS support and goes as far as realising it needs to spawn a Master System. 2018-09-20 22:04:28 -04:00
Thomas Harte
e7f4babf41 Starts taking steps towards SMS/GG and V9938/9958 support. 
Specifically: routine namespace stuff, plus the intention to move to a table-based operation+cost version of timing. Reordering works fine for the TMS, and probably would also for the SMS/GG, but it'd be problematic with the command engine of the V9938/9958 and maintaining a consistent set of code is easier.

a42ca290cb Reformulates the Oric more cleanly into the modern world. 
Specifically: now that the implementation is contained within the CPP file, there's no need to embed the keyboard, tape player and VIA port handler as private classes. Also the pain of additional syntax is reduced, so the keyboard has been bumped up to a fully data-hiding class. I've also transferred overall ownership of the tape player, AY and keyboard up to the Oric itself, with the VIA merely being wired to them, and added a whole bunch of extra documentation.

Thomas Harte
57bfec285f Makes it optional whether the Z80 supports the wait line. If the wait line isn't in use, runtime costs are decreased because the optional wait cycles need not be iterated over. 2017-08-26 23:08:57 -04:00

e7ad79c79a Breaks apart the CPC's 6845 bus handler to obey phase 1 and phase 2, and now back-dates interrupts when appropriate. 2017-08-26 14:07:51 -04:00
Thomas Harte
6e99169348 Permits the 6845's bus state to be examined by an owner, eliminating the need to buffer it in the bus handler. But more than that it allows the CRTC to decide when it adjusts the various outputs respective to the main phase. So a net effect of the change is that the CPC now sees vsync a cycle earlier, because my current reading of the 6845 datasheet is that it is set at the end of phase 1, not the beginning of the next phase 1. 2017-08-26 12:59:59 -04:00

0cbc1753b9 Quick fixes: the binary tape player now considers talk to the sleep observer only if motor control changes.

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

925e774015 Added a decent portion of documentation. But started feeling like I should address my various ownership decisions. Which would justify a separate pull request. 2017-08-16 16:23:33 -04:00
