You have to have specially formatted floppy disks for this machine. You may have to purchase a 3.5" floppy disk drive for your PC to download designs from the internet. Find out if software to do this is included. I think you just need "Organizer" not the zillion dollar full blown package. If they don't have the Organizer, the only other option you would have is to purchase premade design discs, as DonnaJean said, and probably only available on Ebay or purchase Embird embroidery software which is the only other application I'm aware of that will create the disks.
Having said this, I've have my machine for years and it's a real workhorse, both for embroidery and general sewing. It will sew thru anything. You can hem jeans.
PM me if you have more questions.
