Wjman,
Why not buy a floppy and give it a go. The worst that could happen is it won't work. Make sure when you install the floppy that you line up pin 1 on the drive with the red mark(pin 1) on the ribbon cable. And I would use a backup copy of my program as not to loss any data. By the way if you don't line up pin 1 it will mess up all the data on your disk. Been there, done that.
