Where Can I Get A Free Manual For Sonata Compu Sew 6680c?

Ironically, I have a Sonata Compu-sew 6680C that came from the Goodwill.  In Mt Pleasant.  I am also looking for a manual.  Its pretty easy to figure out the basics though.  I'm wondering if the person who asked this question is the person who gave me the machine.  ;)
