b8a1553368 Adds putative support for PlusToo-style BIN files. 
Albeit a bit of a guess, since it's not intended to be an emulator file format.

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.

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.

Thomas Harte
723137c0d4 With some time additions to the 6522, starts wiring in Macintosh audio.

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!

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.
