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.

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.

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.

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!

d9278e9827 Attempts to complete the list of things I can't disassemble.
Mysteries to be solved here, definitely. But: 13 missing opcodes remaining.
2019-04-28 23:11:49 -04:00
Thomas Harte
0298b1b3b7 Implements LINK and UNLINK.
Also starts excluding opcodes that I can't determine the mapping of from the list of those tested against.

Due to those two things together, the latter incomplete: 627 opcodes outstanding. But only STOP and MOVEP remain on my list of things to implement prior to exceptions.

cf547ef569 Improves semantic communications and temporarily omits A- and F-line instructions.
So it looks like 2773 instructions left to go.

40f68b70c1 Adds quantification of reports.
Depressingly; 11,841 opcodes are still missing. Better get on with it!

Thomas Harte
a3b6d2d16e Corrects test and resolves all instances of opcodes that are valid but shouldn't be.
The converse case will require implementation of the remaining instructions.
