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.

e9aaa5bbdf Factors out the page-mapping function. 
For one less potential source of failure.
 2018-07-30 22:23:48 -04:00
Thomas Harte
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.

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.
