5fd2be3c8e Makes a genuine attempt at five and three decoding. 2020-03-25 20:50:26 -04:00
Thomas Harte
2320b5c1fe Takes some steps towards five-and-three decoding. 
Now I 'just' need to figure out how bits are distributed within the decoded sector. The XORing and data checksum seem the same (?)

e5cbdfc67c It turns out that 5-and-3 disks have a different header prologue. 2020-03-24 21:59:55 -04:00

0c2f77305f Eliminates dangling printf. 2020-02-11 22:12:30 -05:00
Thomas Harte
05bcd73f82 Attempts to pull drive ownership into DiskController. 
For the sake of being more intelligent as to drive clocking, hopefully. And, eventually, to support multiple drive selection.
 2020-02-11 21:59:13 -05:00
Thomas Harte
1b27eedf6b Ensure this can definitely never divide by 0. 2020-01-28 23:25:21 -05:00
Thomas Harte
294e09f275 All these 'override's can be 'final's. 
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

c2bd5be51a This seems to be the proper interpretation of speeds? 2020-01-19 20:42:51 -05:00
Thomas Harte
84f5feab70 Properly flags up overloads. 2020-01-19 20:37:54 -05:00
Thomas Harte
5391a699a4 Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation. 
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.

2b4c924399 Makes an effort to locate address and data bodies within track.

 2020-01-09 23:28:07 -05:00
Thomas Harte
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.
 2020-01-09 21:03:01 -05:00
Thomas Harte
985b36da73 Starts towards STX support. 2020-01-07 23:21:32 -05:00

Thomas Harte
274867579b Deploys constexpr as a stricter const. 2019-12-22 00:22:17 -05:00

Thomas Harte
909685d87d A drive with no disk is now happy to spin its motor. 
It'll continue to produce index-hole events, which might not be accurate for 5.25" drives. Research to do.

Thomas Harte
962275c22a Removes clock for NCR 5380. 
It doesn't have one in real life, and now can live off the time counting that occurs on the SCSI bus.

Thomas Harte
2ce1f0a3b1 Implements multi-sector read/write.

 2019-09-16 22:20:42 -04:00
Thomas Harte
210129c3a1 Updated as per Inside Macintosh IV. 
Of which I now own a copy.
 2019-09-16 21:31:43 -04:00
Thomas Harte
934901447a Adds a temporary version of block access writing. 
Whatever I'm doing, it's still not correct. The Macintosh ostensibly appears to 0-fill the direct-access device, then reads a sector back and hangs.
 2019-09-15 22:06:45 -04:00
Thomas Harte
c849188016 Adds format and write to the SCSI target. 
Now I think I need to switch back to the 5380 to ensure proper DMA mode interactions when writing.
 2019-09-12 21:58:09 -04:00
Thomas Harte
87e8dade2f Implements READ BUFFER to do, you know, *something*. Plus READ CAPACITY.

 2019-09-11 21:52:02 -04:00
Thomas Harte
6fc5b4e825 Simplifies INQUIRY for future targets; implements enough of SENSE MODE to advance. 
The HD SC setup utility is now looking to read buffer.
 2019-09-08 21:59:56 -04:00
