Thomas Harte	ddcdd07dd0	Modifies the Vic-20 and C1540 to bring them into the realm of self-ROM fetching. ... Hence enables Vic-20 support within kiosk mode as currently drafted.	2017-11-07 21:19:51 -05:00
Thomas Harte	0116d7f071	Added a platform-neutral route for feeding ROMs to machines, in a platform-dependant fashion; implemented for the CPC.	2017-11-05 20:12:01 -05:00

Thomas Harte	9e0907ee76	Completes clean-up of post-formalisation per-machine keyboard code. ... At least for now. Standardising on how column + row is encoded might be helpful.	2017-10-21 10:52:35 -04:00
Thomas Harte	9ad4025138	Relocates things that were in Machines/ for machine usage. ... Leaving only those things intended to be visible interface.	2017-10-21 10:30:02 -04:00
Thomas Harte	5c141af734	Prevents undefined behaviour from the CPC's timer.	2017-10-17 22:40:32 -04:00
Thomas Harte	da580e4186	Merge branch 'master' into UniversalInput	2017-10-17 22:36:22 -04:00
Thomas Harte	ce78d9d12c	Introduces buffer alignment when writing to textures. ... To avoid cross-boundary writes and hopefully to eke out a little better performance.	2017-10-17 22:09:48 -04:00
Thomas Harte	edbc60a3fb	Various undefined behaviour fixes. ... Primarily around uninitialised variables, but also with an attempted use of a negative pointer.	2017-10-17 21:29:19 -04:00
Thomas Harte	0c2dd62328	Various undefined behaviour fixes. ... Primarily around uninitialised variables, but also with an attempted use of a negative pointer.	2017-10-17 20:50:46 -04:00
Thomas Harte	78ee46270b	Transfers possession of keyboard mappings from the Mac side over to individual machines. ... Specifically by establishing an intermediate representation of a useful mix between the American and British IBM and Mac keyboard layouts, and routing through that.	2017-10-12 22:25:02 -04:00
Thomas Harte	edb9fd301c	Begins this project's conversion to functional-style casts.	2017-10-03 22:04:15 -04:00
Thomas Harte	da082673d7	Drives now have a finite number of heads. ... The Amstrad volunteers itself to be single sided. Everything else stays as it was.	2017-09-15 21:18:36 -04:00
Thomas Harte	d3c385b471	Separates the 8272's drive selection signalling from actual drive ownership. ... Thereby returns working motor control to the CPC.	2017-09-11 21:25:26 -04:00
Thomas Harte	96bf133924	Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed. ... In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.	2017-09-10 22:56:05 -04:00
Thomas Harte	0622187ddf	Strips Controller of all capabilities now housed on the Drive.	2017-09-10 19:23:23 -04:00
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
Thomas Harte	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
Thomas Harte	ee71be0e7e	Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.	2017-08-21 21:56:42 -04:00
Thomas Harte	cde29c4bf4	Added forceinlines and properly declared finals and overrides.	2017-08-21 21:07:10 -04:00
Thomas Harte	e1aded0d95	Allows Z80 users to opt out of support for the bus request line. Which both now do.	2017-08-21 20:43:12 -04:00
Thomas Harte	0cbc1753b9	Quick fixes: the binary tape player now considers talk to the sleep observer only if motor control changes. The Amstrad CPC no longer attempts to use the component argument to identify the caller, since this will often be that of the superclass and not that of the derived class known to the CPC.	2017-08-20 13:18:46 -04:00
Thomas Harte	8f5ae4a326	The CPC now responds to tape-originating sleeper observations.	2017-08-20 12:21:02 -04:00
Thomas Harte	e88a51e75e	Worked logic all the way down to the CPC. If the 8272 announces that it is asleep, it is now no longer clocked. Also very slightly cut down on IRQ line chatter to the Z80.	2017-08-20 12:05:00 -04:00
Thomas Harte	85253a5876	Sought further to reduce the processing footprint of palette changes by updating only those table entries that are affected by a change.	2017-08-20 10:13:23 -04:00
Thomas Harte	911ee5a0d3	At least added a fast return.	2017-08-19 22:22:51 -04:00
Thomas Harte	57c5b38a6d	Step one towards cutting much of this cost: build only the table that's appropriate for the current mode, and at least declare when a more minimal change would be sufficient.	2017-08-19 22:19:46 -04:00
Thomas Harte	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
Thomas Harte	b476f06524	Slowed the typer, having discovered that otherwise it has problems transitioning from a shifted to an unshifted character.	2017-08-16 22:12:16 -04:00
Thomas Harte	3947347d88	Introduces active input handling for the AY and uses it in the CPC to give proper, active keyboard input, rather than push-on-select, which was only ever a temporary hack. Also maps a few more keys for the Amstrad.	2017-08-15 22:47:17 -04:00
Thomas Harte	334872d374	Clarified, slightly.	2017-08-14 12:47:11 -04:00
Thomas Harte	7ea703f150	Started making provisions for a DMA-compatible implementation. Re: the CPC, it sounds like DMA acknowledge might be permanently wired, causing DMA mode seemingly to work from the 8272's point of view.	2017-08-14 08:38:00 -04:00
Thomas Harte	1d8edf58dd	Ensured that a virtual destructor is declared, so that the various automatically-generated real constructors get in on the action.	2017-08-11 12:07:48 -04:00
Thomas Harte	4785e316ff	Now with exposition.	2017-08-11 11:36:03 -04:00
Thomas Harte	44da9de5b0	Tweaked typing timing expectations.	2017-08-11 11:35:28 -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	cf810d8357	Minor: ensure the CRT is set to output as a monitor.	2017-08-10 14:42:47 -04:00
Thomas Harte	4961fda2a9	Ensured counter-intuitive CRTC writes get through, taking the opportunity to correct my handling of port IO in general: selecting multiple devices for input results in a logical AND (i.e. open collector mode), and both the CRTC and gate array will receive data from 'input's if applicable.	2017-08-10 12:39:19 -04:00
Thomas Harte	6a6e5ae79c	Forced users of the 6845 to be explicit about which type. So far with no effect.	2017-08-10 12:28:57 -04:00
Thomas Harte	484524d781	Implements RAM paging. The 6128 is now emulated.	2017-08-08 16:01:56 -04:00
Thomas Harte	a7103f9333	Disks are now communicated to the 8272. Which is able to handle four of them.	2017-08-06 13:24:14 -04:00
Thomas Harte	29288b690e	Switched disk controllers to be instantiated explicitly in terms of cycles, created an Amstrad-specific subclass of the 8272 to record the direct programmatic availability of all disk motors bundled together, and otherwise adjusted to ensure the thing is clocked and that the motor is enabled and disabled appropriately. The 8272 is also now formally a subclass of the incoming MDM controller.	2017-08-06 09:45:16 -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	9e8645ca7a	Fixed ROM paging port decoding. It should have been fd00 if completely decoded, not df00, but also shouldn't be completely decoded.	2017-08-05 19:24:03 -04:00
Thomas Harte	caf3ac0645	Sought: (i) to instruct the CPC that it should be a 664, not a 464, if given a disk image (at least until I have RAM paging implemented for a 6128); (ii) to support ROM selection within the CPC and allow paging in of AMSDOS.	2017-08-05 19:20:38 -04:00
Thomas Harte	4b19cf60df	Added omitted semicolon.	2017-08-05 09:18:55 -04:00
