have you tried e-bay? or craigslist?

these folks have discs (and a toll free number...maybe they can help)

this place says it has 5.25 floppy drive (but i suspect only 3.5)

these folks have a service that copies data.. http://www.copymyfloppy.com/

you might also contact this place: http://www.floppydisk.com/index.html

also here: http://www.tigerdirect.com/

after you say "floppy" a few times it sounds silly!

goodluck...Laurel
