I've never actually used the multivolume stuff.  But I believe you
do something like:

	tar -M -L <size> -cvf a:<filename>

The <size> must be in Kbytes, and I believe will always get rounded up
to the next 10Kbyte boundary, so you'll have to manually round it down
to get your archive to fit on the device.

If everything works, tar will prompt you after filling each floppy.

Note that tar still goes through the MS-DOS filesystem when doing
this, so the floppies must already be formatted.  I think there is a
way to use the "-F" option to run a program between writing each
floppy, so you could probably use that to format floppies as you go.
