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.

906b6ccdb7 This appears to be sufficient for the Electron to _read_ SCSI. 
So that's step one.

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.

c8beb59172 Attempts properly to track ADB bus activity. 
Output is not yet a valid ADB stream. Work to do.

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).
