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

Thomas Harte
191a7a9386 Reintroduces an empty second drive. 
This prevents the uninitialised disk error. Which is a clue.

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
6c588a1510 Makes some further random swings at tracking the startup procedure. 2019-06-28 13:03:47 -04:00

877b46d2c1 Advances IWM/drive emulation very close to the point of 'Welcome to Macintosh'. 2019-06-15 16:08:54 -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

ccd2cb44a2 Fills in enough of the SCC to allow completion of the Macintosh side of that relationship. 2019-06-12 17:51:50 -04:00
Thomas Harte
ad8b68c998 Switches to a proper form of zero-upon-read data. 
Not that it's necessarily correct.

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.

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
Thomas Harte
8557558bd8 Mildly improves investigatory reporting. 2019-06-03 21:51:45 -04:00
