2244299bd9 Add a bias parameter to allow the entire Brother format to be moved around on
the disk.

323da8272a Hopefully add support for giving the reader a set of required sectors, so if
one is missing then we can tell and the track can be reread.

a4002d2617 Fix a few encoder issues; but while 720kB disks work fine in a real machine,
1440kB disks don't.

d25f96dd24 The IBM encoder now works well enough that my USB floppy drive thinks the disk
is formatted... but has trouble reading sectors above about 1000. Also remember
that encoding MFM needs to keep one bit of state at all times.

ad3a930c6a Do the boilerplate of the IBM encoder. 2020-02-09 23:56:20 +01:00

efa4c933b3 Made the MFM marker byte detection a lot more robust --- prevents false
positives; it looks like the new sampler is producing a little bit of wobble
which randomly spoofs a marker byte now and again. This prevents this from
happening (so far).

6af80d1e5e Improve some messaging. A data record is always pushed, even if it's empty (to
help debugging).

04ff31c348 Add a flag to the IBM decoder to tell it to ignore the logical sector IDs (some
formats don't use these).
