Thomas Harte
3e9fa63799 Adds a receiver for drive-motor control bytes. 
My new belief is that I'm either reading the buffer from the wrong place, or the 68000 isn't filling it for some reason.

Thomas Harte
6d985866ee All proper inputs are now provided to the audio generator. 
Hopefully. The next job is to generate audio. If that sounds correct, then the disk motor speed question can be tackled.
 2019-06-01 15:03:15 -04:00
Thomas Harte
723137c0d4 With some time additions to the 6522, starts wiring in Macintosh audio.

Thomas Harte
41740fb45e Implements video position feedback. 
At a substantial performance cost for now, but I'll worry about that once things are working.

407bbfb379 Pretending the Disk II is an IWM doesn't seem to achieve much. 2019-05-05 18:12:25 -04:00
Thomas Harte
a99ebda513 Takes a first shot at (inverted) Mac video output. 2019-05-04 22:27:58 -04:00
Thomas Harte
537b604fc9 It looks like writes should always go to RAM. 
Now I see the screen buffer being filled with `0xffff`s, along with what is probably disk motor control data.
 2019-05-04 17:29:30 -04:00
Thomas Harte

 2019-05-03 23:40:22 -04:00
Thomas Harte
68392ce6f5 Adds enough of a concept of Mac video to get a properly initialised display. 
Completely empty at present, naturally. Also this is the very first time I've run my 68000 at live speed. From just one data point, it's not terrible. Phew!
 2019-05-03 23:25:42 -04:00

Thomas Harte
c7c21a7e2c Sorry, ColecoVision, it's composite only for you. 2019-02-24 22:37:24 -05:00
Thomas Harte
16731661e8 Switches back to being explicit about the colour burst phase. 
Some sort of phase inversion otherwise seems to be achievable by software that switch modes often.
 2019-02-24 22:28:11 -05:00
Thomas Harte
d4134cd0d8 Restores proper colour phase to the Apple II. 
Given that its timing errors were fixed, this also switches back to using 'default' colour bursts — i.e. ones with implicit phase. The Apple II continues to be an excellent bellwether for issues in the pipeline, and this helps further to ensure that.

Thomas Harte
fd579a019b Introduces a new scan source data type, motivated by the reasoning used by the Oric. 
Specifically: it'll allow PCM sampling of the potentially arbitrary composite generation logic of various machines.
 2018-11-28 20:40:22 -08:00
Thomas Harte
