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.
 2019-09-24 20:13:09 -04:00
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.
 2019-09-22 13:15:01 -04:00
Thomas Harte
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.

Thomas Harte
0e0c789b02 Starts attempting to introduce a direct access device.

 2019-08-17 23:43:42 -04:00
Thomas Harte

2129bfc570 Gets as far as testing ROMs against the missing list. 
Though now it strikes me that I've forgotten to retain the machine name.
 2019-07-22 18:02:48 -04:00
Thomas Harte
8de6cd3f44 Ensures that ROM files can be dragged and dropped into Swift. 
Also adjusts the main window background colour, better to bridge the time between selecting a machine and it starting.
 2019-07-22 17:18:31 -04:00
Thomas Harte
9b9831f28b The Mac port will now at least display a list of missing ROMs. 
It doesn't yet offer the drag-and-drop functionality it promises, however.
 2019-07-22 13:00:17 -04:00
Thomas Harte

Thomas Harte
fe0dc4df88 Starts building out some tests for Apple GCR encoding. 2019-06-15 22:48:24 -04:00
Thomas Harte
bde975a3b9 Possibly mights the tiniest bit of headway with 'the IWM'. 
I'm now pretty sure that my 3.5" drive, which for now is implemented in the IWM (yuck) is just responding to queries incorrectly.
 2019-06-13 22:38:09 -04:00
Thomas Harte
f6f9024631 Corrects Macintosh aspect ratio (and framing). 2019-06-13 18:41:38 -04:00

Thomas Harte
b8a1553368 Adds putative support for PlusToo-style BIN files. 
Albeit a bit of a guess, since it's not intended to be an emulator file format.
 2019-06-04 21:41:09 -04:00
Thomas Harte
517cca251f Corrected: the repository shouldn't default to a Release build. 2019-06-04 15:41:36 -04:00
Thomas Harte
661fe1e649 Disables logging, for now. 2019-06-03 15:57:53 -04:00
Thomas Harte

To provide another variable to help with bug isolation.
 2019-06-03 14:50:36 -04:00
Thomas Harte

Thomas Harte
3e9fa63799 Adds a receiver for drive-motor control bytes. 
My new belief is that I'm either reading the buffer from the wrong place, or the 68000 isn't filling it for some reason.
 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.
 2019-06-01 14:39:40 -04:00
Thomas Harte
254132b83d Eliminates 6522Base in pursuit of working handshake modes. 
Specifically: this means that the places from which the BusHandler may be called are more numerous.
 2019-05-08 12:35:17 -04:00
Thomas Harte
7e6d4f5a3e Adds emulation of the real-time clock. 2019-05-08 00:12:19 -04:00

417a3e1540 Adds missing call to flush. 2019-05-03 23:31:12 -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!
 2019-05-03 23:25:42 -04:00
Thomas Harte

Thomas Harte
52e33e861c Starts to introduce the QL as a second source for 68000 testing. 
It's advantageous over the ST in that a commented disassembly of the ROM is available.
 2019-04-14 22:15:09 -04:00
Thomas Harte
2c5ff9ada0 Switches to running the real TOS, at least temporarily, and enables better testing. 2019-03-31 22:27:57 -04:00

Thomas Harte
f9101de956 This might very well be the 68000's first real gasp: performing an ABCD. 2019-03-14 19:32:15 -04:00
Thomas Harte
89c71f9119 Introduces EmuTOS, and starts constructing test cases around it. 2019-03-10 18:40:12 -04:00
Thomas Harte
a4f6db6719 Removes ArrayBuilderTests as the ArrayBuilder is long gone. Disables TIA tests for now. 2019-03-10 18:07:23 -04:00

b9b52b7c8b Begins some very early sketching out of a 68000. 2019-03-09 00:00:23 -05:00
Thomas Harte
86a6b04d4a Begins attempts to keep track of display metrics. 
i.e. a system that can both make smart decisions about when to use a lower resolution, and hopefully allow some sort of flywheel-esque horizontal retrace synchronisation. And possibly some raster beam chasing?
 2019-03-04 21:54:50 -05:00
Thomas Harte
2beeaa513b Ensures a machine exists before messaging it. 2019-03-02 21:27:34 -05:00
Thomas Harte
bee0d09877 Splits display update and draw functions. 
On the Mac, draw is now called without an update for resizing events, and
anything else requested by AppKit. In all other cases — including from
the SDL version — both are called as if they were still a single function.
 2019-03-02 19:33:28 -05:00

Thomas Harte
a697a2e4f6 Attempts to complete all input processing — an RGB, S-Video or composite input buffer is now produced. 
... for all input data types.
 2018-11-22 17:20:31 -05:00
Thomas Harte
75bc0e451d Reintroduces the accumulation texture. 
Disables automatic clearing of the texture target, as the profiler indicates the vector instantiation to be a huge time sink.
 2018-11-18 21:39:11 -05:00
Thomas Harte
8a699b6072 Kills setup_output definitively, saving some indirection. set_scan_target takes its place. 2018-11-14 21:52:57 -05:00
Thomas Harte
91b19c5c70 Adds bookending, and finally kills the TextureBuilder. Farewell. 2018-11-14 20:49:06 -05:00

Thomas Harte
938d09f34a Corrects scan outline generation. 2018-11-12 18:23:45 -05:00
Thomas Harte
dce52d740d Finally gets some pixels back on screen. 
For now, just the raw scans, direct to the framebuffer, with no intermediate processing. But it seems to prove that at least some of the proper data is reaching the GPU.
 2018-11-11 23:23:42 -05:00
Thomas Harte
3ae333fa84 Edges further towards reviving the shaders. 2018-11-11 21:41:13 -05:00

Thomas Harte
b40211d2c0 Starts to bend 'CRTMachine' to a world farther from owning the GPU relationship. 2018-11-03 21:54:25 -04:00
Thomas Harte
da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT. 
Does away with the hassle of `unsigned` while I'm here; that was a schoolboy error.
 2018-11-03 19:58:44 -04:00
Thomas Harte
c128ddb549 Introduces a first unit test for line interrupts and corrects backup behaviour. 2018-10-09 21:49:21 -04:00

e3b4aebf1a Introduces the Disk II as a unique media target platform. 
As it makes a little more sense to analyse Apple GCR images to determine target platform than it does to have the potential platforms vote over them.

Thomas Harte
bc2f58e9de Starts the process of adding an SDL-based 'kiosk' (i.e. TV UI, or even UI-less for now) mode.

6547102511 Attempts better to hide C1540 implementation details from the reader. 
In this case not from the compiler, as it's desireable to keep `run_for` as a non-virtual call, and therefore everything else comes alone for the ride.

Thomas Harte
b034d4e6f8 Refactors the Z80 to separate out interface and implementation. 
Following the pattern just established by the 6502, puts all implementation specifics beyond the visibility of a human reading Z80.hpp and in subfolders so as to promote the idea that they shouldn't go out of their way.
 2017-09-01 20:50:24 -04:00
Thomas Harte
b306776ba9 Removes from 6502.hpp all remaining implementation details, making it purely an interface document. 
Though those details remain visible to files including 6502.hpp through necessity.
 2017-09-01 19:46:29 -04:00
Thomas Harte
4af333d5ec Tidies the 6502 template and folder hierarchy. 
Specifically: there's now just the one .h file at the top level, giving a clear indication of what a user should read. That separates implementation from interface. It also devolves a lot more to the base class because doing so makes debug builds less of a hassle. The all-RAM 6502 has been shuffled off into a subfolder, to indicate that it's not something you necessarily need know about. Also general documentation improvements have been applied: incorrect citing of the recurring-template pattern has been removed and the meaning of the two BusHandler methods has now accrued at the bus handler.

e6683e7f2d Added the base skeletal stuff of HFE support. 2017-08-17 21:48:48 -04:00
Thomas Harte
06e31f5102 Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'. 2017-08-16 12:39:15 -04:00
Thomas Harte
6cfc3daacb Introduced a test within the disk controller so as not to request illegal tracks from disks, instead automatically substituting an 'unformatted' track. Which is just empty. 2017-08-15 21:52:12 -04:00
Thomas Harte
2d81acb82e Upped C++ standard to C++14 and added an #if that's intended to use the built-in std::gcd when compiled on C++17 or better. Fixed for new signedness warnings resulting for taking the step to C++14. 2017-08-11 19:18:45 -04:00
Thomas Harte
570d25214e Made an initial attempt at typer support for the CPC. 2017-08-11 11:21:07 -04:00
Thomas Harte
6a65c7a52a Started working on a CPC-oriented analyser; for now I just want to be able to make a good guess at the appropriate file to load from a disk. As it turns out, the CPC simply adopts the CP/M format, so a generic parser is appropriate. This is its beginning. 2017-08-10 17:10:21 -04:00
Thomas Harte
4d60b8801c Started trying to factor out just the PLL stream -> FM/MFM events part that is presently in the WD1770. 2017-08-05 22:26:15 -04:00
Thomas Harte
3e984e75b6 Strung up an empty shell that eventually should contain the 8272, and added appropriate IO decoding to the Amstrad. 2017-08-05 19:45:52 -04:00
Thomas Harte
75c59fefab Added an empty husk to begin support for Amstrad CPC disk image formats. 2017-08-05 10:02:10 -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
681d1e2f8d Breaking its typer for now, adapted the ZX80/81 to having a Z80, not being one. 2017-08-02 22:12:59 -04:00
Thomas Harte
6ca07f1e28 I guess it might end up living somewhere else, but introduced a header with the compiler-specific stuff to allow me to force things inline. 2017-08-01 22:04:58 -04:00
Thomas Harte
08ad35efd9 It's barely an implementation of the 8255, but ensured that data is bounced into the PortHandler, conveniently assuming the interaction mode used by the CPC. 2017-08-01 16:34:13 -04:00
Thomas Harte
58b98267fc Formally transferred ownership of PIO accesses to an incoming template, and decided to start being explicit about how to specify the interfaces and provide fallbacks for optional behaviour for the new, clean generation of interfaces. A full-project sweep will inevitably occur but I'll try to tie off this branch first. 2017-08-01 16:15:19 -04:00
Thomas Harte
ace71280a0 Removed implementation file; this is only ever going to be a template. 2017-08-01 16:00:17 -04:00
Thomas Harte
2b168f7383 Disabled the address sanitiser as an every-time run again, as it just pushes my computer a bit too far. 2017-07-31 22:32:56 -04:00
Thomas Harte
68ceeab610 Created a 6845 class and started pushing data at it and clocking it. It doesn't currently have the concept of a bus but will do, hence the in-header implementation. 2017-07-31 19:56:59 -04:00
Thomas Harte
26b6c03a2a Re-enabled the address sanitiser as a development tool. 2017-07-31 07:30:07 -04:00
Thomas Harte
c0f1313830 Performed sufficient wiring to get to the point where attempting to load a CDT creates an instance of the Amstrad CPC and then fails only because the thing vends a nullptr CRT. 2017-07-30 22:05:29 -04:00
Thomas Harte
5b5720fac0 Added to the static analyser the most basic through-path for Amstrad CPC content. 2017-07-30 21:15:20 -04:00
Thomas Harte
6ec4e4e3d7 Merge branch 'master' into Memptr 2017-07-25 23:01:34 -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
75d67ee770 Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts. 2017-07-25 20:20:55 -04:00
Thomas Harte
1ba3f262a2 Sketched out a template for clock-receiving components to allow them to be implemented in terms of either half or whole cycles. 2017-07-22 21:46:50 -04:00
Thomas Harte
660f0e4c40 Added Objective-C through wiring and a Swift test class for Memptr modifications. So far with a single test, that fails. 2017-07-21 22:52:25 -04:00
Thomas Harte
2a7fc86b15 Enabled stricter warnings. 2017-07-21 20:44:35 -04:00
Thomas Harte
8f72fc4a44 Factored out from the UEF implementation the concept of being a tape that has a queue of pending pulses and manages that queue. 2017-07-16 22:04:40 -04:00
Thomas Harte
238348c885 Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required. 2017-07-16 21:33:11 -04:00
Thomas Harte
368bff1a82 Added a shell class that will one day be able to parse CSW files, plus the logic and metadata to instantiate it when a CSW presents itself. 2017-07-10 21:43:58 -04:00
Thomas Harte
3e5c209039 Added basic Typer support for the ZX80 and '81. 2017-07-09 22:00:34 -04:00
Thomas Harte
28412150e6 Added controls for controlling the tape motor of the ZX80/81, assuming I can find an automatic option. 2017-07-08 17:59:33 -04:00
Thomas Harte
cb105fdeb4 Took a first stab at high-res support. 2017-06-22 22:48:17 -04:00
Thomas Harte
aec4fd066b I think I've definitively decided against this model of timing. 2017-06-22 21:32:14 -04:00
Thomas Harte
ac37424878 Set up a test class to allow me to discover which of the machine cycle sequences I'm in error on. 2017-06-15 19:06:59 -04:00
Thomas Harte
77aa3c187e Rebranded ZX80O as ZX80O81P, with an eye to making it accept ZX81 .p files. Adjusted the initial selection part of the static analyser appropriately. 2017-06-11 21:38:32 -04:00
Thomas Harte
7e10c7f9d8 Relocated the ZX80/81 concept of a 'file' out from Tape into Data, given that it's an exact duplicate of memory. 2017-06-08 19:09:51 -04:00
Thomas Harte
60300851ea Started sketching out a tape parser for ZX80 and '81 files. I think this'll help me to verify whether the .O input is working. 2017-06-07 10:12:13 -04:00
Thomas Harte
8c66e1d99d Factored out ZX80/81 video and rejigged to ensure it will keep ticking over irrespective of whether the machine is supplying data. 2017-06-06 17:53:23 -04:00
Thomas Harte
b0a7c58287 Fixed project to point to the XIB I actually want to keep; fixed that XIB to have the correct contents. 2017-06-04 17:57:37 -04:00
Thomas Harte
d2637123c4 Added necessary support to get as far as an empty window when attempting to load a piece of ZX80 software. 2017-06-04 17:55:19 -04:00
Thomas Harte
02b7c3d1b0 Added the necessary wiring to get into a ZX80/81-oriented part of the static analyser, which could in principle post a ZX80 target. 2017-06-04 17:04:06 -04:00
Thomas Harte
8c1769f157 Made a quick attempt at serialising from ZX80 .O to waves. 2017-06-04 16:59:26 -04:00
Thomas Harte
655809517c Ensured that there is a subclass of file that is entrusted to load .O/.80 files, and that the code routes such files to it, noting that it should consider whether a ZX80 is required. 2017-06-04 16:37:03 -04:00
Thomas Harte
fd6623b5a5 Attempted to bring a common hierarchy to the Z80 and 6502 test machines, particularly with a view to eliminating the special-case Jam stuff on the 6502. 2017-06-03 21:22:16 -04:00
Thomas Harte
b304c3a4b9 Eliminated the 6502's reliance on the micro-op scheduler. 2017-06-03 20:30:07 -04:00
Thomas Harte
3e9212aaff Plumbed through to allow interrupt tests, wrote an NMI test, corrected the error revealed. 2017-06-03 17:41:45 -04:00
Thomas Harte
7bddd294c9 Resolved an unpredictable conditional and temporarily disabled the Zexalltest as part of the default suite, since it takes so long to run. 2017-05-30 21:03:02 -04:00
Thomas Harte
244b5ba3c2 Added a proper termination condition for Zexall and, for now, a Mhz counter. 2017-05-30 18:32:38 -04:00
Thomas Harte
c6185baa99 Fixed R incrementation and attempted to make the status flags cheaper to write to. 2017-05-29 22:23:19 -04:00
Thomas Harte
4d4695032c Discovered that Zexall is just really slow. Disabled the address sanitiser, and started working towards a verifiable end. 2017-05-29 21:46:00 -04:00
Thomas Harte
3c6f63abcc Started towards running the FUSE tests. Just need to deal with the memory segments. 2017-05-25 19:12:59 -04:00
Thomas Harte
e3e461d7cb Added a test class for running the FUSE tests. With nothing much in it. 2017-05-21 22:49:24 -04:00
Thomas Harte
01a064dd63 Added an empty ED page. 2017-05-20 17:29:30 -04:00
Thomas Harte
11d05fb3b8 Expanded a little on operations, added an implementation or two. 2017-05-19 19:18:35 -04:00
Thomas Harte
58efca835f Sought to add a further opcode. 2017-05-18 22:53:43 -04:00
Thomas Harte
87a021ec2d Made further attempt to get as fas as having the Z80 attempt to do something. 2017-05-16 22:19:40 -04:00
Thomas Harte
189317b80c Added enough of a Z80 test machine to bridge up into Swift. 2017-05-16 22:05:42 -04:00
Thomas Harte
7190f927b7 Factored out the stuff that both all-RAM processors would share, rather than duplicating it. 2017-05-16 21:28:17 -04:00
Thomas Harte
d559d8b901 Continued edging towards getting the absolute basics of a testable Z80, for test-driven development. Corrected old-fashioned instance naming issues with the corresponding 6502 class and removed an unnecessary source file while at it. 2017-05-16 21:19:17 -04:00
Thomas Harte
df80c37adb Renamed TestMachine to TestMachine6502 since there's going to be multiple of them. 2017-05-15 08:18:57 -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
b81a2cc273 First tentative steps towards adding a Z80 implementation. 2017-05-14 17:46:41 -04:00

Thomas Harte
c033bad0b9 Here's MNetwork! 2017-03-18 20:51:49 -04:00
Thomas Harte
c31d85f820 Re-emplaced the MegaBoy. Also cut detritus from the main Atari header. 2017-03-18 19:02:34 -04:00
Thomas Harte
217fbf257e CBS RAM Plus returns. 2017-03-18 18:56:20 -04:00
Thomas Harte
0b611a14b9 Tigervision paging returns. 2017-03-18 18:50:13 -04:00
Thomas Harte
df6861c9dc Parker Bros paging is back. 2017-03-18 18:21:01 -04:00
Thomas Harte
a4cd12394e Reinstated the Activision stack pager. 2017-03-18 18:03:48 -04:00
Thomas Harte
bb3daaa99b Sought to reintroduce the Atari 8k paging scheme, at the same time deciding to do away with the copy and paste of holding on to ROM data. 2017-03-18 15:04:01 -04:00
Thomas Harte
14a76af0d3 Started trying to float out bus control to cartridges. 2017-03-17 20:28:07 -04:00
Thomas Harte
57ec756f5b Started speccing out a unit test for Atari ROM analysis. 2017-03-11 20:33:58 -05:00
Thomas Harte
a72d70e707 Enabled code coverage calculation for unit tests. 2017-03-11 17:44:56 -05:00
Thomas Harte
cd90118a0f Added two, extraordinarily simple tests. 2017-02-12 20:32:53 -05:00
Thomas Harte
92754ace7a Some mild fixes get me up to having a rolling screen of vertical lines. Which is what I was hoping for right now! 2017-01-29 22:16:23 -05:00
Thomas Harte
d51f185dc7 Made an attempt to reintroduce the basic horizontal loop. 2017-01-29 15:43:57 -05:00
Thomas Harte
0ffded72a6 Created a placeholder class for a factored-out TIA. There's a bit more it'll need to do, like vending (or receiving) a CRT but this is the full hardware stuff, I think. 2017-01-28 16:19:08 -05:00
Thomas Harte
9001cc3fc2 Added a cartridge image. 2017-01-27 21:26:11 -05:00
Thomas Harte
015b2b49f9 Introduced an incomplete set of file association icons. 2017-01-26 22:21:55 -05:00
Thomas Harte
7b696b0962 Switched scheme to shared. 2016-12-31 13:11:07 -05:00
Thomas Harte
99993a1b24 Since it's about to become important that objective results match, added a couple of objective-result tests for the CRC generator. 2016-12-27 19:03:46 -05:00
Thomas Harte
e25195a718 Added a single test for Storage::Time, discovering that I had the wrong sign on float conversions. 2016-12-24 22:59:01 -05:00
Thomas Harte
e081f224b6 Implemented a very basic PCMTrack test, nevertheless revealing an oversight in PCMSegmentEventSource related to improperly counting to the index hole if the final bit is set. Took that as a message that I should comment and document the event source. 2016-12-18 22:53:24 -05:00
Thomas Harte
a6354ebb01 Reimplemented PCMTrack to use PCMSegmentEventSource, eliminating code duplication. 2016-12-18 21:37:05 -05:00
Thomas Harte
3116a2cf4c Realised I was actually testing PCMSegmentEventSource, not PCMSegment; implemented a spread of tests; hence fixed PCMSegmentEventSource. 2016-12-17 21:47:13 -05:00
Thomas Harte
254cc41fd6 Made an attempt to separate and isolate the stuff of creating flux events from a PCMSegment, eventually to factor that out of PCMTrack and make it available also to PCMPatchedTrack. 2016-12-17 21:13:57 -05:00
Thomas Harte
3017062e89 Maybe TDD is the way to get over my activity block on this thing? Fixed the existing ArrayBuilder tests so that the tests target builds again, added an extremely trivial PCMTrack test, heading towards PCMPatchedTrack tests. 2016-12-17 17:05:49 -05:00
Thomas Harte
dc08a23ceb This is going to be a slow walk, I think. This class attempts to be the scratchpad which will hold in-memory track modifications. 2016-12-16 19:20:38 -05:00
Thomas Harte
c43e481a33 Started factoring video out of the Electron. 2016-12-10 21:07:52 -05:00
Thomas Harte

Thomas Harte
3361d6b93a Factored out the Atari 2600 speaker and adjusted it to postfix underscores. 2016-12-03 13:39:46 -05:00
