d53b38ec7e Correction: 0xc011 et al get the keyboard value in bits 0 to 6 and the switch value in bit 7. 2018-08-30 20:18:36 -04:00

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.

76a73c835c Forces 6502 consumers to declare which model — the original, 65C02 or 65SC02. 
All present machines use a regular 6502.

de68e70246 Fixes various IIe video deficiencies. 
Specifically:
* the double-high resolution switches should be read/write; and
* the other IIe-specific switches should cause a video update for real-time effect.

ce14cc8677 Flips meaning of analogue input bits, correcting most joystick titles. 
Mysteriously, some functioned correctly before this. But they continue to do so.

086596c28e Adds reading of vertical blank and implements the full IIe keyboard logic. 
i.e. there are now two Apple keys, and shift isn't assumed.

c773d3501a Implements the INTC8ROM switch. 
Finally causing the Zellyn tests to pass! Is this nightmare behind me?

e9aaa5bbdf Factors out the page-mapping function. 
For one less potential source of failure.

ecb26e3281 Corrections: slot_C3_rom_ works the other way around; 80STORE doesn't affect most of RAM but does always affect the text screen. 
Also factored out `set_zero_page_paging` for consistency.

bc2afe69e1 Accepting that memory mapping on a IIe is more complicated than I anticiapted, introduces mapping for all pages. 
Also picks a name for the Unenhanced Apple IIe ROM.

ede2696a77 Edges further towards implementing the IIe video subsystem. 
All video-specific switches are in place, and mostly honoured, and a IIe machine configuration is advertised at least.

59b9e39022 Starts the process of supporting the Apple IIe graphics modes. 
Albeit that I'm not yet even up on the proper soft switches.

51da21b844 Formally introduces keyboard-as-joystick for the Mac, and fixes discovered joystick issues. 
Specifically:
* digital to analogue conversion not returning to centre;
* Apple II axes being the wrong way around; and
* Apple II buttons using improper selection logic.

f1b430338e Makes the Apple II a joystick machine. 
Albeit that the values supplied to its joysticks do not currently make it into the emulated state.

d576ff1172 Exposes DOS 3.3 acceleration as an option. 
Albeit with an unhelpful label in the macOS GUI for now.
