Rework the bytecode format to use a much simplified setup: a six-bit timer with
...
the top two bits reserved for pulse and index state. This is actually smaller,
bandwidth-wise, than the old version, and may be smaller than the crunched
version.

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.

When reading data records, retry if we get an UNKNOWN record to work the
...
occasional false positive (which happens now and again with MFM).

Improve some messaging. A data record is always pushed, even if it's empty (to

help debugging).

Radically simplify RawRecord and Sector. It all works, and the results are
...
better, but I've disabled a bunch of decoders for now.

The new decoder architecture now works, at least for the FB100. All I need now

is to rewrite every single other decoder.

Refactor so track state is passed around in the Track object.

Moderately crudely hack in routing side information to the decoders; this is
...
needed by the Victor 9000 decoder to figure out the right clock rate.
2019-04-16 19:50:25 +02:00
David Given
9b59e7025d
Add the ability for decoders to specify their own clocks --- necessary for the
...
Victor 9k. We now have _much_ better decoding for this platform.
2019-04-16 01:13:28 +02:00
David Given

Add stateful decoders, which makes formats like the FB-100 much easier to work
...
with. Add a generic CRC tool allowing all the parameters to be set (currently
unused).

Hard sector segmentation can now cope with the extra index hole. We are

correctly decoding the Zilog MCZ disk.

Splitting by hard sectors works, up to a point; we can correctly decode (with

CRC checking!) most of the Zilog MCS disk. However, we're still stumped by the
extra index hole.

things).

Use a bit more statistical nous when trying to sense the bit rate, and use the

median of the pulse to pick the normative clock rate.
