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.

Thomas Harte
39aae34323 Avoids multiple calls to -[NSCursor hide] and -unhide.

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
517cca251f Corrected: the repository shouldn't default to a Release build. 2019-06-04 15:41:36 -04:00

Thomas Harte
85298319fa Expands towards supporting multiple Macintosh models. 
To provide another variable to help with bug isolation.
 2019-06-03 14:50:36 -04:00

881feb1bd3 Adds preliminary parsing of the Disk Copy 4.2 format. 2019-06-02 13:39:25 -04:00
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.
 2019-06-01 19:31:32 -04:00
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. 
The audio buffer is also the disk motor buffer, so this is preparatory to further disk work.

5e2496d59c Simplifies and corrects MOVE logic. 2019-05-28 15:17:03 -04:00
Thomas Harte
c52da9d802 Adds some logging preparatory to a MOVE change. 2019-05-28 15:05:42 -04:00
Thomas Harte
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.
 2019-05-08 12:35:17 -04:00

7e6d4f5a3e Adds emulation of the real-time clock. 2019-05-08 00:12:19 -04:00
Thomas Harte
96facc103a Adds an IWM shim and corrects graphics output. 
... now that there is some.
 2019-05-05 21:55:34 -04:00

417a3e1540 Adds missing call to flush. 2019-05-03 23:31:12 -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

6873f62ad8 Ensures that the Mac now retains its ROM properly. 2019-05-03 22:39:09 -04:00
Thomas Harte
5f385e15f6 Adds the bare bones necessary to be able to create a Macintosh from File -> New... . 2019-05-03 22:16:07 -04:00
Thomas Harte

Correcting issues uncovered.
 2019-05-02 00:00:09 -04:00
Thomas Harte
bb07206c55 Corrects internet response to work as currently implemented. 
Also makes corrections to the bus error and address error exceptions.
 2019-05-01 21:59:06 -04:00
Thomas Harte
e430f2658f Adds a test and by that means fixes divide-by-zero exception return addresses. 2019-04-29 23:09:50 -04:00
Thomas Harte
7332c64964 Improves testing of function as distinct from timing. 2019-04-29 22:08:37 -04:00
Thomas Harte
d6e16d0042 Adds a test of TOS 1.00, as far as it goes without meaningful hardware. 2019-04-29 18:04:57 -04:00
Thomas Harte
8e02d29ae6 Trims test to length of trace capture. 2019-04-29 17:56:49 -04:00
Thomas Harte
c0e9c37cc7 Improves memory map model, as far as it goes. 2019-04-29 17:27:44 -04:00

Thomas Harte
c466b6f9e7 Factors out the [unit testing] stuff of being a trace-checking 68000 bus handler. 2019-04-29 16:11:01 -04:00
Thomas Harte
407643c575 Tweaks test length slightly to ensure this doesn't run beyond the final line's end. 2019-04-29 15:40:17 -04:00
Thomas Harte
d9071ee9f1 Starts sketching out the asynchronous bus. 2019-04-29 13:45:53 -04:00
Thomas Harte
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.
 2019-04-28 17:12:31 -04:00

cf547ef569 Improves semantic communications and temporarily omits A- and F-line instructions. 
So it looks like 2773 instructions left to go.
 2019-04-27 15:15:03 -04:00
Thomas Harte
40f68b70c1 Adds quantification of reports. 
Depressingly; 11,841 opcodes are still missing. Better get on with it!
 2019-04-26 13:25:34 -04:00
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.
