Yes, exactly as above. The cards can be read to your computer with PE Basic reader/ writer , Magic Box, or other boxes that will read/ write. You got good advice to ask around of your embroidery friends who can read and save to CD for you. I would be happy to do so, but I'm in Tennessee, USA. After the cards are copied for you, perhaps you can sell them.
If you get the cards read, then convert to your format with free softwares...Wings My Editor, Pulse Ambassador, WilcomTruesizer, several others.
