From the command line, try
	od -c </dev/rfd0a
to view as ascii, or
	od -x </dev/rfd0a
to view as hex, or
	od -s[n] </dev/rfd0a
to view only null-terminated strings with at least n charactes.

Since I don't have a floppy drive I don't know 100% if /dev/rfd0a is
the right device, but I'm pretty sure.

The whole thing might be faster if you read with dd instead, thus
	dd if=/dev/rfd0a bs=18K of=- | od -c
etc.
