Shouldn't be too difficult to figure out what kinds of disk images you are
looking at.

Regardless of the sector interleaving table in use, Tk00 Sec00 should always
be
physical sector 00, in which case it will be at the beginning of a DSK file,
be it
".DSK", ".PAS", etc.

There are sufficiently different byte patterns that you could check to
differentiate
between DOS33, ProDOS, Pascal, CP/M.
