3d1ee7a43e Don't spin in an infinite loop if the decoder tries to find a data record and 
the matcher fails to find anything, leaving the seek point unchanged.

18d90c44dd Rework the flux decoders to add a desync opcode for separating multiple reads 
in a flux stream. Finally add a unit test for the flux decoder.

29e8c99b4f Hopefully get the imagereader/imagewriter and IBM encoder/decoders using sector 
IDs.

8b115f8156 Convert the IBM encoder/decoder to use lists of sector IDs rather than 
sector_skew strings.

c087539eb7 swap_sides isn't symmetrical for the encoder and the decoder. On the encoder, 
it affects which logical side is being written to which physical side. On the
decoder, it modifies the logical side bit in the sector header itself.

786b35fee2 Fix swap_sides on the ibm encoder/decoder to work; remember to specify it for 
both the encoder and decoder.

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
David Given
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).
