Thomas Harte	85c5c4405a	Ensured that wait states don't appear unless requested (TODO: requesting), and made the output of my timing tests a little easier to parse.	2017-06-19 07:30:01 -04:00
Thomas Harte	d668879ba6	Started trying to wade back to passing tests. Working on the new timing tests first, and focussing on getting the Objective-C test machine to compile bus operations into machine cycles, which means indicating phase to all-RAM delegates.	2017-06-18 22:03:13 -04:00
Thomas Harte	e1a2580b2a	Renamed BusOperation to MachineCycle::Operation.	2017-06-17 21:53:45 -04:00
Thomas Harte	b6f51474ff	Ensured that -description can handle the newly-captured bus actions.	2017-06-17 18:20:30 -04:00
Thomas Harte	0f18768091	Disabled attempts at bus activity matching within the FUSE tests, at least until I settle on exactly what I intend to do.	2017-06-17 18:19:25 -04:00
Thomas Harte	50cd617bd9	Ensured test raises only the intentional failure exceptions.	2017-06-15 22:33:46 -04:00
Thomas Harte	838b818cd3	Finished transcribing first page of machine cycle documentation; several failures contained.	2017-06-15 22:19:49 -04:00
Thomas Harte	cf795562bf	Continued filling in tests, fleshing out what the test machine captures as a result.	2017-06-15 20:59:59 -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	aed2827e7b	Implemented a rudimentary way to test that instructions take as long as the FUSE tests think they should. Hence discovered that the (HL)-accessing BIT, RES and SET weren't. Corrected.	2017-06-12 22:22:00 -04:00
Thomas Harte	a48616a138	Fixed reference to Swift-world MachineDocument for the ZX81 file type.	2017-06-12 18:51:11 -04:00
Thomas Harte	8222aac9e3	Added an official declaration of support for ZX81 files.	2017-06-11 21:40:41 -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	8116f85479	Allowed the static analyser to specify a ZX80 or 81, and a memory model. Neither is respected yet in the machine.	2017-06-11 19:12:20 -04:00
Thomas Harte	50be3a24fe	Sought to ensure that Mode 1 interrupts aren't happening early. Which they seem not to be.	2017-06-11 13:30:08 -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	cc4cb45e9d	Implemented keyboard input and ensured that the signal generated is marked as composite, putting the colour-suppression ball into the CRT's court.	2017-06-06 09:25:18 -04:00
Thomas Harte	c485c460f7	Imported the ZX80 and 81 system ROMs (though not publicly), added enough code to post their contents into C++ world.	2017-06-04 18:08:35 -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	2190f60a89	Reinstated manual-by-stealth secondary usage of the Zexall test as a benchmarking tool.	2017-06-04 15:46:35 -04:00
Thomas Harte	0eebfdb4cc	Expanded emulation of memptr, though still incomplete. Reverted zexall tests to zexdoc. Will probably leave memptr until I've an emulated machine as test suites seem to exist, but they're machine-dependant, so figuring out how to isolate them from an architecture will be a lot easier if and when I have functioning machines.	2017-06-04 15:39:37 -04:00
Thomas Harte	7811374b0f	Started sneaking in memptr emulation, hopefully to get to a working BIT (hl).	2017-06-04 15:07:07 -04:00
Thomas Harte	87095b0578	Undid consciously discard for bits 3 and 5 in the FUSE tests. Back to 100 failures.	2017-06-04 14:04:26 -04:00
Thomas Harte	b642d9f712	Eliminates the 6502's specialised jam handler in favour of the generic trap handler, and simplifies the lookup costs of that as it's otherwise doubling execution costs.	2017-06-03 21:54:42 -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	b3da16911f	Tweaked timing of mode 0, per contradictory information. Wrote a failing test of mode 2.	2017-06-03 18:42:54 -04:00
Thomas Harte	e52892f75b	Added a test of interrupt mode 1.	2017-06-03 18:16:13 -04:00
Thomas Harte	8c41a0f0ed	Added a test to confirm interrupts are disabled, and a response to the interrupt cycle within the all-RAM machine.	2017-06-03 17:53:44 -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	d14902700a	Minor syntax and wiring fixes.	2017-06-01 22:33:05 -04:00
Thomas Harte	c95c32a9fe	Implemented the reset line program and disabled fictitious automatic power-on reset for the Z80 test machine.	2017-06-01 22:31:04 -04:00
Thomas Harte	494ce073b5	Tests having been fixed by instating proper Z80 cycle counting, removed caveman logging.	2017-05-31 19:58:57 -04:00
Thomas Harte	5ff73faf48	Ensured Zexall can pass.	2017-05-31 19:55:06 -04:00
Thomas Harte	2f7f11e2e5	Added diagnosis props.	2017-05-31 06:54:25 -04:00
Thomas Harte	5119997122	Made an attempt, flawed so far, to find a neat way for processor subclasses to offer bus management as an inline function.	2017-05-30 22:41:23 -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	960de7bd7b	Marginally reduced test machine costs based on usage.	2017-05-30 11:59:07 -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	6d22f6fcd5	Having decided the bus operation error on 10 is probably in the test cases, decided to allow myself to skip that one comparison. Back to zero failing cases, and with no more useful information to derive from the FUSE test set for the time being.	2017-05-29 17:17:17 -04:00
Thomas Harte	8bfaa487ce	Improved logging of bus operations and corrected placement of the OUT step in that repetition group; was otherwise outputting the wrong side of the B adjustment and therefore to the wrong port (if interpreted as 16 bit).	2017-05-29 17:13:24 -04:00
Thomas Harte	267b2add9a	Adjusted for where FUSE nominally places timestamps. Down to 92 failures.	2017-05-29 16:44:07 -04:00
