022ec20e75 Tries to add semantic meaning to the various auxiliary control fields.
To consider: decoding at set?

41f69405d8 Don't decrement timer 1 from the system clock when in PB6 mode.
TODO: rest of PB6 mode.

8e242eea54 Ensures timer-linked PB7 output is actually output. 2020-09-20 15:03:26 -04:00
Thomas Harte
703065a0a5 Takes a run at timer-linked PB7 output behaviour.
Seemingly sufficiently to pass the VICE test (which I've transcribed), though with some guesswork.

e807a462a1 My new reading is that only a write to the counter should affect the interrupt flag. 2020-09-17 21:31:29 -04:00
Thomas Harte
18790a90ae Ensures timer 2 doesn't use timed behaviour when in pulse mode. 2020-09-17 21:09:32 -04:00

31c6faf3c8 Adds a bunch of consts. 2020-05-09 21:23:52 -04:00

c1bae49a92 Standardises on read and write for bus accesses.
Logic being: name these things for the bus action they model, not the effect they have.

1c154131f9 Expands size of storage in Cycles/HalfCycles; adjusts widely to compensate. 2019-10-29 22:36:29 -04:00

ee8d853fcb Ensures you can't get a phase 2 for free with run_for(0). 2019-07-17 14:20:27 -04:00

245e27c893 Solidifies belief that the shift register bit is cleared on read/write. 2019-07-08 16:45:15 -04:00
Thomas Harte
28de629c08 Fixes the 6522 sufficiently to fix keyboard input. 2019-07-08 15:29:34 -04:00
Thomas Harte
210bcaa56d Introduces an initial shift unit test, and makes it pass. 2019-07-07 22:13:36 -04:00
Thomas Harte
9230969f43 Corrects enough of the 6522 and Keyboard to get an initial command seemingly working. 2019-06-10 09:28:27 -04:00
Thomas Harte
0e16c67805 Improves shift register connection, towards having the keyboard function properly.
It now seems not to receive a command terminator, but is at least getting a command.

abe55fe950 Adds Timer 1 toggling of PB7. 2019-06-03 15:39:20 -04:00
Thomas Harte
723137c0d4 With some time additions to the 6522, starts wiring in Macintosh audio.
The audio buffer is also the disk motor buffer, so this is preparatory to further disk work.

4367459cf2 Takes a first go at handshake and pulse modes. 2019-05-08 12:48:29 -04:00
Thomas Harte
254132b83d Eliminates 6522Base in pursuit of working handshake modes.
Specifically: this means that the places from which the BusHandler may be called are more numerous.

Thomas Harte
24b3faa427 Deconstitutes the 6522 into component parts, templated and non-templated.
Adjusts the Oric, Vic-20 and C-1540 accordingly, albeit with the quickest possible solutions.
