Corrects internet response to work as currently implemented.
...
Also makes corrections to the bus error and address error exceptions.

Adds a test and by that means fixes divide-by-zero exception return addresses.

Improves testing of function as distinct from timing.

d9278e9827
Attempts to complete the list of things I can't disassemble.
...
Mysteries to be solved here, definitely. But: 13 missing opcodes remaining.

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.

Improves semantic communications and temporarily omits A- and F-line instructions.
...
So it looks like 2773 instructions left to go.

Thomas Harte
40f68b70c1
Adds quantification of reports.
...
Depressingly; 11,841 opcodes are still missing. Better get on with it!

Thomas Harte

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.

Adds tests for MOVE.l (An), Dn, and thereby correct their implementation.
2019-03-23 21:41:47 -04:00
Thomas Harte
d7c3d4ce52
Adds test for MOVEA.w (0x1000), A1 and fixes implementation thereof.

Extends to a failing test.
2019-03-21 23:32:03 -04:00
Thomas Harte
fdc598f2e1
Starts MOVE tests; in pursuit of which talks the 68000 into obeying run lengths.

Thomas Harte
0d7bbdad54
Begins a basic get/set state API, allowing some actual unit tests, implying an ABCD fix.
2019-03-17 21:57:00 -04:00
Thomas Harte
388d808536
Switches to providing UDS and LDS implicitly via address.
...
Also makes sure that the difference between a non-data cycle that starts without the address strobe active and one that starts with it active can be discerned.

Adds an implementation of SBCD and slightly neatens syntax for building programs.
2019-03-14 21:22:02 -04:00

This might very well be the 68000's first real gasp: performing an ABCD.
