d17fadbe0b Avoid off-by-one error in sector decoding.
Specific issue: retaining the 256 bytes up to _and including_ the checksum, rather than excluding.

8da7806ee9 Liberalises segment parser not necessarily to require a standard epilogue.
It seems that real disks don't always have them; I guess the boot ROM doesn't require one.

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

Thomas Harte
e9318efeb6 Switches to std::make_shared/make_unique in a bunch of applicable places.
No doubt many more similar improvements are available, these are just the ones that were easy to find.

Thomas Harte
df56e6fe53 Fixed: the sector number also goes into sector bodies.
Also the checksum is written in the other order, and the final byte of data isn't output.

555c2a4377 Makes a first sweep at converting the storage underlying PCMSegment to vector<bool>.
This is to remove another pain point, in preparation for the work immediately forthcoming but also work as-yet unknown.
