Thomas Harte
07df7572b3 Switch to preferred Acorn-world extension: DAT. 2021-01-31 21:03:09 -05:00
Thomas Harte
906b6ccdb7 This appears to be sufficient for the Electron to _read_ SCSI. 
So that's step one.

f1ba040dd8 This is probably how Acorn hard disk images look (?) 2021-01-31 16:00:52 -05:00
Thomas Harte
8db289e229 Adds some notes-to-self on SCSI and a route to using Acorn's ADFS. 2021-01-31 13:12:59 -05:00

Merge pull request #865 from TomHarte/ADL 
Electron: adds support for the ADL file format, and logic for AP6 and sideways RAM selection
 2021-01-31 09:37:24 -05:00
Thomas Harte
0bb8bdf938 Switch to O(1) test, which avoids an extra #include. 2021-01-30 23:33:03 -05:00
Thomas Harte
865058b8d6 Adds basic text search to achieve AP6 detection. 2021-01-30 23:32:04 -05:00
Thomas Harte
b6bc0a21fb Adds a TODO on intended logic around the AP6 ROM. 
... plus a promise as to intent in the Electron-specific ROM readme.
 2021-01-30 23:20:43 -05:00
Thomas Harte

Merge pull request #863 from TomHarte/DecodersAhoy 
Sketches out the concept of a `Decoder`
 2021-01-15 21:14:49 -05:00

9c2c918760 Better sorts by function, corrects TEST description. 2021-01-15 21:07:02 -05:00
Thomas Harte
47d20699d8 Completes list, ensures POP acts as documented. 2021-01-15 20:48:31 -05:00
Thomas Harte
e8ce70dccb Chips further away at documentation. 2021-01-15 18:52:59 -05:00
Thomas Harte
fa4938f29c Establishes the reason I'm sort-of documenting these. 2021-01-15 18:27:55 -05:00
Thomas Harte
ddb4bb1421 Better plans project layout. 2021-01-15 18:16:01 -05:00
Thomas Harte
ca94e9038e Introduces 'far' test, fixes parsing. 2021-01-14 22:15:38 -05:00
Thomas Harte
2c72a77a25 Adds byte-by-byte decoder test; corrects divergences. 2021-01-13 21:51:18 -05:00
Thomas Harte
8c0e06e645 Adds a test for 0x83 and fixes sign extension. 
ODA doesn't seem to accept 0x82, but testing 0x83 adds some confidence.
 2021-01-13 20:42:21 -05:00
Thomas Harte
a24ae727a7 Takes a run at 0x82 and 0x83, completing the set. 2021-01-13 20:29:44 -05:00
Thomas Harte
5058a8b96a Completes the first test stream. 
... and improves decoding consistency in conjunction.
 2021-01-12 21:49:22 -05:00
Thomas Harte
762ecab3aa Adds operand/displacement capture. 
This gets unit test as far as a disagreement over how to handle bad 0xc4 suffixes.
 2021-01-10 22:55:25 -05:00
Thomas Harte
9ba5b7c1d4 Adds a few more asserts. 
It's still just operands and displacements failing, which is nice.
 2021-01-08 23:21:01 -05:00
Thomas Harte
5f807b6e47 Ensures that the operand is the only thing failing in decoding of the first instruction. 2021-01-08 23:02:06 -05:00
Thomas Harte
718f950071 Implements 80 and 81. 2021-01-08 22:50:59 -05:00
Thomas Harte
68fe16a092 Marks intent for operand/displacement. 2021-01-08 22:45:27 -05:00
Thomas Harte
97a64db5e0 Edges closer towards full x86 recording. 2021-01-08 22:38:56 -05:00
Thomas Harte
86577b772b Rethinks size; packs all captured information into an x86 Instruction. 
Albeit that operand and displacement are't yet captured. Or extractable.
 2021-01-08 22:22:07 -05:00
Thomas Harte
306df7554e Starts trying to find a good packing for X86 instructions. 
To consider: do I really need `size` on every instruction?
 2021-01-08 21:33:01 -05:00
Thomas Harte
30c2c0f050 Attempts to complete operand recognition. 2021-01-07 21:59:00 -05:00
Thomas Harte
205649cac2 Decodes 8e. 2021-01-07 21:36:05 -05:00
Thomas Harte
fd49b72e31 Simplifies macros, implements d0, d1, d2 and d3. 2021-01-07 21:30:01 -05:00
Thomas Harte
995904993d Fills in 8f, c2, c3, ca and cb. 
Also switches to RETN and RETF for near/far RET as this seems idiomatic.
 2021-01-06 21:18:24 -05:00
Thomas Harte
17cbba85fc Formalises what's missing in terms of opcodes and fills in some blanks. 2021-01-05 21:47:12 -05:00
Thomas Harte
9d7d45338f Ostensibly gets the instruction stream correct for test case 1. 
Subject to operand and displacement currently being absent, and likely inconsistencies in field population, most of which are omitted from the Instruction anyway.
 2021-01-05 21:34:35 -05:00
Thomas Harte
3b55d3f158 Nudges up to a need to decode operation from the ModRegRM byte. 2021-01-05 21:25:12 -05:00
Thomas Harte
fda2293d6b Improves constness. 2021-01-04 22:36:39 -05:00

Merge pull request #862 from MaddTheSane/madds-patch-1 
Madd's improvements
 2021-01-03 20:53:39 -05:00
Thomas Harte
38bca5f0f0 Finally runs into the wall of trying to merge operands and offsets. 2021-01-03 20:08:13 -05:00
Thomas Harte
a8738b533a Switch for now to block-level decoding. 
It's easier to step debug.
 2021-01-03 20:07:46 -05:00

29cf96c703 Adds decoding of disp16 RETs. 2021-01-03 19:39:28 -05:00
