Glasgow Embedded / Glasgow - History

applet.shugart_floppy: write directly to file in raw2img.

This makes it possible to refresh the destination file on-line.

applet.shugart_floppy: fix missing LBA calculation.

applet.shugart_floppy: tweak PLL for lower desync rate.

before: 1255/2915 sectors missing
after: 913/2915 sectors missing

applet.shugart_floppy: document System 36 track format.

applet.shugart_floppy: implement MFM image extraction.

applet.shugart_floppy: implement MFM image indexing.

Indexing as in it gives you an index of the sectors it found in
the disk image. It does decode the data and verify CRC too, but
doesn't save the decoded bytes anywhere.

cli: add `glasgow tool`, for running offline applet functionality.

Offline as in no Glasgow hardware required.

applet.shugart_floppy: interleave tracks from both sides.

This gives us "LBA" (really logical track addressing) that seems
consistent with what Linux &c use... of course, FAT12 uses CHS
directly.

applet.shugart_floppy: eliminate K.C2 sync, update docs.

K.C2 actually *can* be produced by normal data. Not sure what is
even the point of having it...
