96214bf3fd Refactor for better multi-read support. Each read is now held separately, with 
F_DESYNC being deprecated, and FluxSource returns an iterator which can be used
to retry reads.

549a984eab Add support for writing 120kB Brother disk images. Also add some utils tests, 
because they needed it.

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.

df0a9bac96 More config machinery: the reader now reads (but can't put the resulting image 
anywhere).

bf8f6ae687 Add imagereader offset and step modes, and hardware forty-track modes. Not sure 
this is the right way to do it.

629af2a697 You can now create Bytes from strings and vice versa. 2021-01-04 23:31:54 +01:00

1b48ea20c4 Remove the cruncher. 2020-03-20 00:06:07 +01:00
David Given
fc2655ecd6 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.
 2020-03-14 18:58:43 +00:00
David Given
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.
 2020-02-21 22:14:44 +01:00
David Given
8acf8e181d Rework the crunch encoding to be, hopefully, smaller and use less bandwidth for 
HD disks.
 2020-02-18 21:37:32 +01:00

89a27619ff Correctly propagate MFM encoding state. 2020-02-15 21:47:01 +01:00
David Given
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.
 2020-02-14 00:06:51 +01:00

e8febe6508 Allow converting Bytes to bits, and slicing until the end of an object. 2020-02-14 00:04:31 +01:00

792cc88192 The Amiga writer now generates valid flux files --- but it looks like the 
writer's broken (both the Amiga and the Brother have failed).

f9117b8d11 Added a simple library for reading and writing LDBS files. 2019-08-09 22:41:07 +02:00

a1c207cb8f First milestone towards flags rewrite --- it builds and the tests pass, but 
nothing actually works.
 2019-07-02 23:06:40 +02:00
David Given
4e3d4e31af The flux pattern matcher will now preserve leading zeroes (although it can't 
match them). The IBM decoder is now properly converted, autodetecting FM and
MFM.

bec46419d6 Remove the obsolete FluxPatterns. 2019-04-27 10:27:55 +02:00
David Given
a483ad987e Archival checking: IBM FM works (but not MFM yet). Other formats have stopped 
working.
 2019-04-26 23:52:04 +02:00

643288bef8 Extend the flux pattern matcher to support trailing zeroes. 2019-04-25 23:18:47 +02:00
