What to do with 3.5 (?) inch computer discs?

<p>My embroidery sewing machine uses 3.5" floppy drives. Asked about converting to USB and was told it’d be $600. Not in my budget. Updating the sewing machine and associated software to more current models would be multiples of that. </p>

<p>I am still a Luddite. (Just don’t mail me any disks! I have a good supply.) :)</p>
