dc4a0e4e3b Video only ever reads from RAM, so it can be const *. 
(it can also be *const, since I set it only once)
 2019-10-27 14:09:38 -04:00
Thomas Harte
95c45b5515 This can be const. 2019-10-20 17:22:56 -04:00

Thomas Harte
da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT.

Thomas Harte
78eaecb29e Provides the proper framework for encapsulation of analyser target specifics.

6b1eef572b Eliminates diamond inheritance of KeyboardMachine::Machine by typers. 
Specifically by pulling the key action stuff into a purely abstract class [/interface]. Takes the opportunity to unpublish a bunch of machine details.

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
ad9df4bb90 Commutes uint8_t *, uint16_t *, uint32_t *, size_t, off_t and long to functional-style casts. 2017-10-21 22:30:15 -04:00

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

edb9fd301c Begins this project's conversion to functional-style casts. 2017-10-03 22:04:15 -04:00

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

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
75208b0762 Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere. 2017-08-16 15:33:40 -04:00
Thomas Harte
903a17ae11 Corrected typo and removed replication of what's already declared formally. 2017-08-16 14:53:03 -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
