7d778bc328
Formally introduces fast tape support as an option.
...
It doesn't feel that fast yet though.

It seems a full CRC is in play.
2021-03-12 22:45:48 -05:00
Thomas Harte
a32a2f36be
Advances to correctly reading bytes.
...
Something is still amiss though. Maybe I'm supposed to update the checksum?
2021-03-12 19:15:35 -05:00
Thomas Harte
cd215ef521
Stumbles towards supporting fast tape loading.
...
Right now: in a non-optional manner.

Makes absolutely sure not to try to use quickboot workaround for Mac 128kb/512kb.
...
Albeit that it should be harmless; it's just seeding RAM.

This conditional is gone.

Further consolidates region map, now that shadowing is orthogonal.

Thanks to a hint from the MAME guys: finally completes Macintosh 128kb and 512kb emulation (!)
2021-02-26 21:22:35 -05:00
Thomas Harte
55c9d152e9
Slightly smarter: this does branchless shadowing without additional storage.

3d91b0a31b
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.
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?

Amongst ever more cruft, adds a couple of extra asserts.
2021-02-18 22:49:48 -05:00

This may temporarily exhaust my wit for asserts.

Asserts even more overtly.

Adds service requests. The microcontroller now appears to consume keyboard events.

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.
2021-02-14 20:37:33 -05:00
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.
2021-02-14 18:54:22 -05:00
