a2a928e262 Takes a guess at the format of IIgs .po files; wires them through to the actual machine. 
... which still declines to boot.

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.

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.

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

54352cb1cb Stubs in a couple more registers. 
PC now hits $0000. Likely a bug.

7e106c6add Attempts to stub in read from microcontroller, and extends command 0x06. 
A complete guess on the latter, as if you didn't know.

0ae49b356a Seems to do enough padding out to get me to my second failing ADB command. 
That's better than failing at the first.

3bb3d8c5c1 Adds text colour register. 
Oddly this isn't currently being set. So probably another latent fault elsewhere.
 2020-11-07 23:14:50 -05:00
Thomas Harte
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.
 2020-11-07 22:23:48 -05:00

d3c7253981 Shifts size-limiting of X and Y to transitions and mutations, away from reads. 
Primarily to remove potential bug-causing complexity — this is easier to debug. But let's see.
 2020-11-04 20:35:41 -05:00
Thomas Harte
0178aaee2b Attempts retroactively to enforce the rule that 8-bit index modes => no top byte.

dd6769bfbc Splits OPLL and OPL2 classes. 
Logic is: they have different mixers (additive in the OPL2, time-division multiplexing in the OPLL) as well as different register sets. So I'll put operator and channel logic directly into those structs.

294e09f275 All these 'override's can be 'final's. 
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

533729638c It seems like Jasmin paged in at boot, and button = page back in and reset works?
