2b4c924399 Makes an effort to locate address and data bodies within track. 
"Not completely successful" would be the polite term.

64517a02b7 Adds code to deal with sector-free tracks. 2020-01-09 21:50:32 -05:00
Thomas Harte
b4befd57a9 Advances to being able to cope with STXs with no special features whatsoever. 
Well, other than perhaps a broken data CRC. Fuzzy bits, timing differences and the stuff between sectors are all currently absent.

Merge pull request #720 from TomHarte/Jasmin 
Adds emulation of the Oric's Jasmin disk interface.
 2020-01-05 22:13:11 -05:00
Thomas Harte
3ced31043a Makes Jasmin autoboot optional, adds a Jasmin reset key, adds the Jasmin to File -> New... . 
Also finally implements KeyNMI.
 2020-01-05 21:57:33 -05:00
Thomas Harte
7361e7ec34 Fixed: the issue was failing to propagate motor control. 
Also it seems to be incorrect to have the Jasmin paged at initial boot.
 2020-01-05 21:35:20 -05:00
Thomas Harte
533729638c It seems like Jasmin paged in at boot, and button = page back in and reset works? 
At least, that gets me a 'boot failed' error. Which is something.

9f30be1c13 Attempts to implement most of a Jasmin disk interface. 
With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.

09289f383d Makes an effort to detect Jasmin disks, and flags the target if found. 
It'll try the Jasmin only if the Microdisc check fails; this is because the latter is preferable — it automatically boots, and is much better tested in Clock Signal terms.

Merge pull request #719 from TomHarte/CleanUps 
Standardises on `read` and `write` for bus accesses.
 2020-01-05 13:59:02 -05:00
Thomas Harte
c1bae49a92 Standardises on read and write for bus accesses. 
Logic being: name these things for the bus action they model, not the effect they have.

Merge pull request #718 from TomHarte/BusErrorStack 
Adds a test and fixes for the bus error stack frame.
 2020-01-05 00:08:53 -05:00
Thomas Harte
9f2f547932 Adds and satisfies test on the function code word. 
Thanks to ijor's "68000 Address and Bus Error Stack Frame" re: contents.

f0d5bbecf2 Introduces a test of stack contents after an address error. 
Fixes: stacked PC, address of fault.

I completely withdraw my earlier statement re: the test cases.

Merge pull request #715 from TomHarte/TestsRedux 
After rerunning all tests, adds some notes on questionable results.

937cba8978 After rerunning all tests, adds some notes on questionable results. 
Also renames a file. But no code changes are currently suggested, at least until I can learn more about DIVU/DIVS.

Merge pull request #714 from TomHarte/STJoystick 
Adds Joystick key code mode, ensures events aren't posted in interrogation mode.
 2020-01-04 10:01:57 -05:00
Thomas Harte
19ddfae6d6 Adds Joystick key code mode, ensures events aren't posted in interrogation mode. 
This should fix Turrican due to the latter change; I'm not aware of software that uses the former.

Merge pull request #713 from TomHarte/MULUS 
Adds DIV and MUL tests, correcting some DIV flags.
 2020-01-04 09:22:03 -05:00
Thomas Harte
7de1181213 Make a new guess at post-overflow DIV flags, based on tests. 
Specifically: for DIVU, stick with the current guess of a fixed set. For DIVS, leave N and Z alone.
 2020-01-03 23:44:49 -05:00
Thomas Harte
c7a5b054db There's no TODO here; overflow is always 0 for a 16x16 multiply. 
... and the original 68000 doesn't support 32x32 multiplies.

Thomas Harte
5be30b1f7b Introduces further comparative tests, prompting a new CHK fix. 
Specifically: how to set N when both is_under and is_over are true, and to eliminate a failure fully to prefetch in the longer addressing modes.
