b0fc2f6ecf Amps up logging. 
Current suspicion is that the IIgs isn't getting a clean byte stream, never mind whether my assumption of exactly-Mac-style GCR holds (which it probably doesn't).

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

72884c3ead Does a better job of shifting output; takes a new guess at the no-receiver case. 
ROM03 at least now reaches "check startup device!"

80358cf5bd Shift output even if nobody is listening. 2020-11-11 20:04:48 -05:00

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.

6d511f01a4 Ensures intended no-drive behaviour; no more risks with dangling pointers or nullptr. 2020-11-11 17:54:21 -05:00

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.)

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.

287bfeb924 Hacks in 40-column text. 
Hot gossip: my IIgs is reporting a system error. A clue!

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.

5126163c5d Attempts to reduce pull request heft. 
Given that the licensing of krom's tests is uncertain, and I've given credit and an appropriate link, I needn't include the original code.

9e2a6526d1 Corrects interpretation of bit 3 of the state register. 
And attempts to be a bit more careful with the language card in general.
