It'd be nice if there was a FAQ about floppy formats in general TBH.
Covering some of the different geomery and encoding schemes out there
etc. (not necessarily mentioning any machines by name).

Hmm, I don't really know how it could be structured, but the same floppy
questions seem to crop up time and time again.

It'd also be a good place to mention some of the different controlling
hardware out there (catweasel, SCSI floppy controllers etc.)

Or go nuts and turn it into a small ftp site with a FAQ *and* docs /
specs for different formats, hardware etc.
