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	ad8c8166bc	Built in gamma conversion for all machines, assuming an output of 2.8 for PAL, 2.2 for NTSC.	2017-08-10 15:17:08 -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	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	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	9d43784c65	Significantly increased quantity of keys forwarded.	2017-08-01 20:37:55 -04:00
Thomas Harte	f5b278d683	Added enough stuff to put the emulated Amstrad CPC in a state of knowing whether its '0' key is pressed.	2017-08-01 17:31:56 -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	0536f089e1	Eliminated old-[personal-]fashioned line break.	2017-07-31 22:32:26 -04:00
Thomas Harte	3df13cddd4	As per my keenness for cleanliness improvements corresponding to my ever-increasing C++ ability: turned the Amstrad into something that a factory produces, allowing me completely to hide a bunch of implementation details.	2017-07-31 22:32:04 -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	afd409c883	Ensured that ROM images are loaded and passed to the Amstrad CPC.	2017-07-31 18:44:49 -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	d25d7d7d40	Added the Amstrad CPC as a named target and declared support for its CDT file format.	2017-07-29 21:56:33 -04:00
Thomas Harte	761afad118	Corrected timestamp return, and its testing by the 6502 timing tests.	2017-07-27 21:19:16 -04:00
Thomas Harte	37950143fc	Attempted to nudge wait timing onto half-cycle boundaries, which expands the number of partial machine cycles the Z80 can post but pleasingly also regularises them. Switched the AllRAMProcessor to reporting half cycles by default and corrected all Z80 tests.	2017-07-27 20:17:13 -04:00
Thomas Harte	9257a3f6d7	Added test for 16-bit arithmetic, and fixed implementation.	2017-07-26 19:04:52 -04:00
Thomas Harte	728143247d	Added a test for RLD and RRD. Which already passes.	2017-07-26 18:56:35 -04:00
Thomas Harte	6ec4e4e3d7	Merge branch 'master' into Memptr	2017-07-25 23:01:34 -04:00
Thomas Harte	37ccb9d3b6	Fixed 6502 timing tests.	2017-07-25 23:00:39 -04:00
Thomas Harte	3c254360ba	Completed fixture of the 6502 BCD test.	2017-07-25 22:55:45 -04:00
Thomas Harte	3ca51bedc6	Discovered legitimate uses of the jam opcode so reinstated it. Corrected illegitimate uses.	2017-07-25 22:48:44 -04:00
Thomas Harte	36076b7ea5	Eliminated final vestige of professed jam handling. This should make it clear which tests still think they can capture jams.	2017-07-25 22:38:26 -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	df4732be2e	Corrected test.	2017-07-24 22:33:49 -04:00
Thomas Harte	9435c1e12a	The 1540 is now a ClockReceiver.	2017-07-24 22:32:41 -04:00
Thomas Harte	2912d7055b	The 6532 is now a ClockReceiver.	2017-07-24 21:57:24 -04:00
Thomas Harte	13f7aa4063	The TIA is now a ClockReceiver.	2017-07-24 21:48:34 -04:00
Thomas Harte	b3ae920746	Converted the DPLL and disk controller classes to be ClockReceivers.	2017-07-24 21:04:47 -04:00
Thomas Harte	e6578defcd	It turns out that quite a few tests still rely on CSTestMachine6502JamOpcode. Though since it no longer works, that'll need to be fixed. In the meantime, fixed the test build process at least, as it's not really what this branch is meant to be invested in.	2017-07-23 22:22:50 -04:00
Thomas Harte	ace8e30818	Bubbled the Z80's move into clock receiver territory up into the Z80 test machine.	2017-07-23 22:21:39 -04:00
Thomas Harte	b0c2325adc	Corrected run call, and accepted that jam handling is gone forever.	2017-07-22 22:21:26 -04:00
Thomas Harte	2ff157cf7a	Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.	2017-07-22 22:17:29 -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	4ea835e50b	Added test for EX (SP), rp, which passes.	2017-07-22 17:17:32 -04:00
Thomas Harte	5fddbec132	Merge branch 'master' into Memptr	2017-07-22 17:06:22 -04:00
Thomas Harte	6633537fb8	Discovering that there is such a thing as P81 — a ZX81 file without the name omitted — added support for it. Extended FileHolder while I was here to retain the file name and be able to supply its extension, as my quick-fix test-the-last-character approach to o/p/80/81 discrimination stops working with p81 thrown into the mix and this feels like the correct factoring.	2017-07-22 16:02:25 -04:00
Thomas Harte	6437c43147	Added CPI and CPD tests: at last two that pass without requiring implementation changes!	2017-07-22 12:38:18 -04:00
Thomas Harte	5928a24803	Transcribed missing tests as TODOs.	2017-07-22 11:44:17 -04:00
Thomas Harte	20a6bcc676	Added tests for the various LD (nn), rr instructions and corrected implementation to pass.	2017-07-22 11:39:13 -04:00
