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	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	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	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	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	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	244b5ba3c2	Added a proper termination condition for Zexall and, for now, a Mhz counter.	2017-05-30 18:32:38 -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	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
