I actually own a pair of 40 track 3.5" floppy drives, of course as they
are connected to an IEEE-488 interface I won't be using them with my
CoCo. Personally I think that the IT.DNS bit doesn't matter at all on
3.5" floppies as long as people which are consistent, which we have not
been. Both ways make their own kind of sense (for example it is more
than a bit of a pain to have to have different disk images which differ
by a single bit between 80T 5.25" and 80T 3.5" versions).
