f50e8b5106 If I'm going to maintain the max_address approach, & is 'correct'. 
% +1 would be 'more correct', but I think this approach is probably misguided.

 2021-01-23 22:55:12 -05:00

Thomas Harte
55de98fb46 Adds a new statement of intent. 
Now I need to try to decide whether I like my current all-in-one mapping for shadowing + paging, or whether it's better to split the things. I'm tending towards the latter at least until the functionality works.

Yet to optimise, but working.
 2020-11-22 19:10:05 -05:00
Thomas Harte
8fae74f93e Reintroduces delay bit, reverses phase.

Thomas Harte
34794223b4 For now, at least, c800–cfff is always built-in ROM. 
Otherwise I probably need to extend my c3 logic to cover the other built-in cards (?)
 2020-11-18 19:49:45 -05:00
Thomas Harte
96cf617ee6 Advances slightly. I think I need a custom queue for RAM writes. 2020-11-18 19:48:53 -05:00

 2020-11-18 19:47:22 -05:00
Thomas Harte
98347cb1c3 Starts in the direction of audio support. 2020-11-18 18:39:11 -05:00

e4c5bfdd5c Takes a repeat shot at proper shadowing. 
I think the Apple IIgs Technical Reference explains how these bits interact, and I just had inhibit_all_pages off all on my own.
 2020-11-16 19:54:12 -05:00
Thomas Harte

Thomas Harte
1538a02e18 Better explains concern. 2020-11-14 19:27:20 -05:00
Thomas Harte
f9cec9a102 Attempts also to implement 1Mhz access costs. 
Subject to TODO, and same observation as before: this is as to my current understanding only.
 2020-11-14 19:23:01 -05:00
Thomas Harte
adda3d8f42 Attempts a 'full' model of 2.8Mhz access timing.

5698aa6499 Corrects colour mapping and improves documentation for self. 2020-11-11 20:41:30 -05:00
Thomas Harte
a15af1df5e Attempts to use the other bit of disk drive control, the 5.25"/3.5" select. 
For the record, the ROM thinks it finds some Smartport devices and then attempts to talk to them. Since none is present, it blocks forever.
 2020-11-11 17:55:50 -05:00
Thomas Harte
da9e378ab1 Quietens, for now. 2020-11-11 17:53:21 -05:00

Thomas Harte
abb350ff5b Stubs in audio toggle and disk control. 
It appears that ROM 01 now fails because reading the disk interface register doesn't do as expected. ROM 03 starts hitting what should be the IWM and dies in a surplus of logging.
 2020-11-09 22:21:52 -05:00
Thomas Harte
dc8d4d49f5 Gives the two sets of switches responsibility for supplying 'state'. 
(And fixes language-card state value.)
 2020-11-09 22:11:20 -05:00
Thomas Harte
54352cb1cb Stubs in a couple more registers. 
PC now hits $0000. Likely a bug.
 2020-11-09 21:54:25 -05:00

7e106c6add Attempts to stub in read from microcontroller, and extends command 0x06. 
A complete guess on the latter, as if you didn't know.
 2020-11-09 21:20:53 -05:00
Thomas Harte
0ae49b356a Seems to do enough padding out to get me to my second failing ADB command. 
That's better than failing at the first.

 2020-11-08 17:01:23 -05:00
Thomas Harte
81c38c7200 Per the IIgs tech note, this value works the other way around. 2020-11-07 23:15:07 -05:00

3bb3d8c5c1 Adds text colour register. 
Oddly this isn't currently being set. So probably another latent fault elsewhere.

b57a2bfec9 Completes logic for pixel framing. Well, mostly; this doesn't yet allow for auxiliary-using II modes being off to the left. 
The perceived effect though is that a frame appears and then freezes. So a clocking issue may still be afoot.
