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 (?)

It turns out that 5-and-3 disks have a different header prologue.

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.

Ensure this can definitely never divide by 0.

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.

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.
