f668e4a54c Makes an attempt at getting the 5380 past arbitration. 
Not entirely successful. Also gets a bit smarter with `final` on ClockingHint::Sources.

9bbccd89d3 Adds an extended rationale for current implementation. 
Also strips some cruft of prior guesses.

2aa308efdd Tweaks magic formulas. 
The computer now at least seeks outward, until this attempt at drive speed calculation fails.

fb6da1de4a Reduces logging temporarily. 2019-07-08 17:37:15 -04:00
Thomas Harte
191a7a9386 Reintroduces an empty second drive. 
This prevents the uninitialised disk error. Which is a clue.
 2019-07-02 16:59:00 -04:00
Thomas Harte
b9c2c42bc0 Switches drives to using floats for time counting. 
Hopefully to eliminate a lot of unnecessary `Time` work; inaccuracies should still be within tolerable range.
 2019-07-02 15:43:03 -04:00

Thomas Harte
cc7226ae9f Starts trying to get a bit more rigorous about collected meanings. 2019-06-13 22:48:10 -04:00
Thomas Harte
bde975a3b9 Possibly mights the tiniest bit of headway with 'the IWM'. 
I'm now pretty sure that my 3.5" drive, which for now is implemented in the IWM (yuck) is just responding to queries incorrectly.

f6f9024631 Corrects Macintosh aspect ratio (and framing). 2019-06-13 18:41:38 -04:00

Thomas Harte
ad8b68c998 Switches to a proper form of zero-upon-read data. 
Not that it's necessarily correct.
 2019-06-11 19:53:51 -04:00

Thomas Harte
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.
 2019-06-04 21:41:09 -04:00

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.

4197c6f149 Attempts to make some further semantic sense of the various IWM controls. 2019-05-30 22:17:49 -04:00
