5149f290d0 Starts trying to formalise just-in-time execution. 
Which, at least, simplifies Cycle/HalfCycle to Cycle run_for usage via template.

96c0253ee2 Fixes mouse input when a button is pressed; attempts keyboard input. 
I think the VIA is somehow sending spurious commands.

b40211d2c0 Starts to bend 'CRTMachine' to a world farther from owning the GPU relationship. 2018-11-03 21:54:25 -04:00
Thomas Harte
da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT. 
Does away with the hassle of `unsigned` while I'm here; that was a schoolboy error.
 2018-11-03 19:58:44 -04:00
Thomas Harte
a8645f80bf Introduces 'non-exclusive' emulator-space keyboards. 
i.e. sets of keys that don't amount to an entire keyboard in the modern sense. Experimentally used by the Master System for its reset key.
 2018-10-24 21:59:30 -04:00

Thomas Harte
a38639d099 Eliminates the concept of an iCoordinate. 
Real-life precision appears not to support the idea of sub-sample pixel storage.
 2018-09-12 20:05:39 -04:00
Thomas Harte
be01203cc1 Starts to expand the range of supported 6502s. 
This fully implements the NES 6502 because, well, it's virtually no extra work, and ensures that RDY takes effect on write cycles on 65C02s.
 2018-08-13 22:17:22 -04:00
Thomas Harte
76a73c835c Forces 6502 consumers to declare which model — the original, 65C02 or 65SC02. 
All present machines use a regular 6502.

3c33ccd730 Eliminates various blank lines. 2018-07-28 10:52:34 -04:00

3862fdb44c Simplifies initialisation procedure for all machines. 
With the side effect of allowing every machine to try to load only the ROMs that it needs.
 2018-07-10 20:00:46 -04:00
Thomas Harte
c97c5fa03a [Re-]recalibrates CRT retrace period and affected view windows. 
In the hope of moving the CPC closer to the real CTM visible area.
 2018-07-05 22:07:18 -04:00

154c89e041 Introduces a missing separator. 2018-06-21 20:01:04 -04:00
Thomas Harte
685a80f95b Ensures the Electron Plus 3 properly announces drives to an activity observer. 
Does away with lazy allocation as not all that helpful, and liable to cause complexity.
 2018-06-18 21:49:57 -04:00
Thomas Harte
d576ff1172 Exposes DOS 3.3 acceleration as an option. 
Albeit with an unhelpful label in the macOS GUI for now.

Thomas Harte
70e6c3b2f6 Introduces the ActivityObserver protocol for LEDs, drive events, etc. 
The Electron's caps lock LED is the test case.

e92e06a5f4 Doubled down on the ROMMachine::ROMFetcher typedef. 2018-04-23 20:20:14 -07:00
Thomas Harte
6547560e52 Gives the CRT the ability to move iCoordinate multiplication outside of the fragment loop. 
That resolves precision issues, as were plaguing the Apple II.

89bec2919f Encapsulates machine configuration properties for all remaining platforms. 2018-03-09 16:07:29 -05:00
Thomas Harte
78eaecb29e Provides the proper framework for encapsulation of analyser target specifics. 
... while making them a safe container for objects too. Uses the ZX80/81 as the pilot platform.
