I'm not having any luck with either back10 or tito.
$ sha1sum 169249.tape
1230fb20086990a1ff777fce32591f2900425694 169249.tape (So that's good)
$ ./tito -x -f 169249.tape
fopen: Is a directory
$ bin/back10 -l -f 169249.tape | head
18-Nov-1858 00:00:00 <754> dsk:[1,1][3,700202].ufd
18-Nov-1858 00:00:00 <754> dsk:[1,1][3,700004].ufd
18-Nov-1858 00:00:00 <754> dsk:[1,1][3,700220].ufd
$ bin/back10 -x -f 169249.tape
that gets lots of files with names like 'dsk:[1,4]specdf525].mic'
That just seems wrong.
