3d91b0a31b Fixes keyboard data return. 
Input sort of works now! Except that key repeat is way out of control.

5d1970d201 Adds a hacky different guess at how register access might work. 2021-02-19 21:46:18 -05:00
Thomas Harte
72d7901c88 Takes a shot at the keyboard data full flag. 
Just a guess. But likely?

eccf5ca043 Makes first effort to wire up the ADB vertical blank input. 
However: looking at the disassembly, I'm not sure it really is wired to INTR. So work to do.

52cf15c3e6 Attempts to route out modifier state. 2021-02-14 21:15:31 -05:00

a791680e6f Implements set_status as per advice. 2021-02-14 21:04:20 -05:00

2ab3bba695 Attempts GLU register latching, restoring expected startup sequence. 2021-02-13 17:38:42 -05:00

2c4dcf8843 Edges towards implementing an ADB device. 2021-02-12 21:50:24 -05:00

17bac4c8cf Starts to formalise the ADB bus. 2021-02-10 21:24:31 -05:00
Thomas Harte
46bd20b5e0 Attempts to simplify ADB bit parsing. 
On-line output still looks reasonable, albeit that the microcontroller suddenly seems to be interested in devices F and 3 rather than 2 and 3.

93a80a30d3 With correct divider appears to get reset requests posted. 2021-02-07 23:05:01 -05:00

77b1efd176 Sets sensible 'reset' values. 2021-02-07 21:53:57 -05:00

acfab1dfb3 Starts to make some effort at timers. 2021-02-06 21:02:44 -05:00

b8c6d4b153 Rips out my high-level ADB microcontroller protocol implementation. 
Adds just enough that the main computer validates the ADB controller as present and talking.

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.

dcc2fe0990 Improves M50470 entry-point detection, adds test output. 2021-01-26 21:29:17 -05:00

fc4bda0047 Experimentally flipping interpretation of the output bit gives something closer to coherent. 2021-01-25 22:02:39 -05:00
Thomas Harte
c8beb59172 Attempts properly to track ADB bus activity. 
Output is not yet a valid ADB stream. Work to do.

8789ffda15 Corrects performer storage, RMW/W confusion, implicit casts, port readback. 2021-01-24 22:30:42 -05:00
Thomas Harte
e8e604dc3c Attempts to wire up M50470 and GLU. 
Resulting in an unexpected interest in R15. Bugs to find, I guess.

57e0fdfadc Ensures ADB microcontroller is clocked. 
And runs at the 'correct' speed (i.e. modulo my instruction-by-instruction implementation).

ec0018df79 Routes in the ADB keyboard ROM. This should get as far as parsing. 2021-01-18 16:59:49 -05:00

eec27c3406 Reaches for marginally more coherent ADB data. 2020-11-25 17:34:00 -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.

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

46ee98639e Stubs in $c010. 
Also reduces memory map logging.

53f60f7c87 Adds some notes for a pending ADB implementation. 2020-11-01 14:49:04 -05:00
