Thanks to a hint from the MAME guys: finally completes Macintosh 128kb and 512kb emulation (!)
2021-02-26 21:22:35 -05:00

Slightly smarter: this does branchless shadowing without additional storage.

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

Thomas Harte
5d1970d201
Adds a hacky different guess at how register access might work.

Takes a shot at the keyboard data full flag.
...
Just a guess. But likely?

Amongst ever more cruft, adds a couple of extra asserts.

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.

6e53b4c507
Corrects centralised ADB decoder.
...
I still think it's appropriate to do this in only a single place, given that using it is optional.

Thomas Harte
52c38e72f6
Starts seeking to automate register 3 handling.
...
Immediate pitfall: byte capture on the bus side isn't working correctly.

Thomas Harte
a51d143c35
Corrects reactive-device transmission logic.
...
Albeit that I'm still not properly responding to register 3 stuff, so the ADB bus needn't believe anything is out there. Also, without VSYNC being piped to the microcontroller it may well just not be polling anyway.

Adds a helper for decoding ADB commands.
...
Still very noticeably to do: any sort of standard part for devices to respond to the bus.

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.
