ea26f4f7bf Eliminates test code, adds a caveat. 2020-03-25 21:22:30 -04:00

5fd2be3c8e Makes a genuine attempt at five and three decoding. 2020-03-25 20:50:26 -04:00
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 (?)

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.

8f28b33342 Starts work on Macintosh GCR decoding. 2019-07-11 16:28:52 -04:00
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.
 2019-06-18 10:34:10 -04:00
Thomas Harte
5c8aacdc17 Fixes the more obvious issues with GCR encoding: byte order, top bit selection. 2019-06-16 17:17:24 -04:00

3fdefb94e4 Removes requirement for correct sector epilogues. 
It's now a length test that at present accepts 6-and-2 sectors only.
 2018-05-12 23:03:08 -04:00
Thomas Harte
49592ebaf3 Ensures initialisation of scanner and that sectors overlapping the end of track are captured. 2018-05-12 18:42:07 -04:00

f65c65569a Makes disk head position explicitly something with sub-integral precision.

Thomas Harte
e3b4aebf1a Introduces the Disk II as a unique media target platform. 
As it makes a little more sense to analyse Apple GCR images to determine target platform than it does to have the potential platforms vote over them.

Also starts on the parser that'll be necessary for making a decision.

2e20191c01 Relocates and cleans up what is currently written of Apple GCR handling as the encoder.
