Let me ask again, all of you floppy disk fans. What is the useful
information you need when you look at that disk image listing? How do you
normally classify those floppies and drives? TPI? Or tracks?
Capacity?

See the refreshed http://nitros9.sourceforge.net/latest/ where I have
calculated a number of tracks from the "os9 id" output. Would it be an idea
to replace or complement the TPI with this?
