In addition, some third-party systems use 80-track double sides drives, with
the same underlying disk format. These are supported with the `appleii640`
profile. The complication here is that the AppleDOS filesystem only supports up
the same underlying disk format. The full list of formats supported is:
- `--140` 35-track single-sided (the normal Apple II format)
- `--640` 80-track double-sided
`--140` is the default.
The complication here is that the AppleDOS filesystem only supports up
to 50 tracks, so it needs tweaking to support larger disks. It treats the
second side of the disk as a completely different volume. To access these
files, use `--appledos --side1`.
