As a previous poster (George Kamis) noted, Next Step 3.0, can
format, read, and write Macintosh formatted floppy disks.

Two points to mention about it:

    1.  data transfers to and from Mac disks are incredibly
        slow -- it beats tyromancy, but only by a slim margin.

    2.  Writing files is flakey.  There is some (unspecified)
        limit on the number of files you can write, and when you
        hit the limit, the file system on the disk appears to be
        hosed.  Let's hope NeXT can figure this one out soon
        and at least let us know what the limits are.

        I have a hierarchy with fifteen directories and around 430
        files.  The total size of the hierarchy is around 700K --
        only about half of the capacity of a Mac 1.4 MB disk.  The
        limit seems to come somewhere between 100 and 200 files.
        I couldn't see a pattern.  I eventually transferred all
        the files to the Mac, and put all the files onto one disk
        using the Mac.  The NeXT appears to be able to handle
        reading the disk all right -- just writes are flakey.

    3.  (since I promised to mention two points).  Transferring
        files from the NeXT to the Mac does only that --  there's
        no translation services (NL to CR for instance) a la
        FloppyWorks.  In fact, I ended up using FloppyWorks in the
        end to do the translation, as well as to set file type and
        creator.

So be aware that the universe of discourse in NeXT to Mac disks
may not cover all the things required to move files around correctly.

        ........  Henry

A few other things:

1. The Mac file handling has a problem with file names that are too long.  
If you have Mac files nested a few folders deep you may find that you  
can't access the files.

2. When you copy a Mac file to a NeXT filesystem using the file viewer,  
you are only copying the data fork. The resource fork will be ignored.

3. If you want to copy or access the Mac resource fork, you must do it  
from the command-line. It appears as a second file and isn't displayed by  
doing a wildcard ls. For a give file named "bob", "bob" is the data fork  
and "bob.#rsrc#" is the resource fork.
