You know what happens when you assume. :-)

Some PC floppy controllers can handle single density (FM) and others
can't. All can handle double density (MFM). I was lucky with both
motherboards I've used for this, an Asus P2B-F (Pentium 2/3 slot 1) and
an Asus A7M266-D (dual Athlon).

It's easy to get them working in Linux. You just need an appropriate
cable. If you just want a "raw" image, you can use the setfdprm utility
(from the util-linux or fdutils packages) to set the parameters (bytes
per sector, etc.). Then you can dd the contents of the floppy to a file.

I archive the contents of 8-inch disks into DMK format using a
program I wrote called rfloppy, which is part of my dmklib package:
It automatically figures out the characteristics of the floppy.
