The problem, I think, is getting a SCO filesystem mounted on a FreeBSD
directory tree.  The SCO website mentions the Acer File System, which
I'm pretty sure is not supported by FreeBSD.  If you used one of the
several filesystem types mountable by FreeBSD to create the floppy, then
it's simply a matter of tar xvf /mount_point/file.tar.  Other than that,
you'll have to find a SCO machine to read the data in and either rewrite
it to FreeBSD-compatible filesystems on floppies, or, if the SCO machine
is networked, access the data over the wire.

Alternately I belive SCO offers a single-user version for just the cost
of the CD media and S&H, so you *could* go the convoluted path of
installing SCO on a partition to access the data ;-)

        Do they have a real file system on them (not common under Unix)
        or are they just raw tar files (much more common under Unix)?

        If it's just a raw tar file, you can unpack it this way:

                tar -xvf /dev/fd0.1440

        Take a look at /dev/fd0.* devices if you're using a drive other
        then 1.44 megs (normal 3.5" floppy).

Quick hint on working out the type of things:

% file /dev/fd0

doesn't work.  So, do this instead:

% dd if=/dev/fd0 of=/tmp/foo count=8
% file /tmp/foo
/tmp/foo: GNU tar archive

For an ordinary tar archive, or perhaps:

% file /tmp/foo
/tmp/foo: gzip compressed data, deflated, last modified: Thu Jul 30
09:27:34 1998, os: Unix

for a gzipped tarchive.

That's what tar means:

tar -tvf /dev/fd1.1440

tar: Hmm, this doesn't look like a tar archive.
