Husqvarna Embroidery card reader/writer
Hi - I think you have a Viking Designer 1, which has a slot for a floppy disk on the side of the machine. If so, you need to purchase embroidery software that supports file type .sv1, and you will need to buy floppy disks.
You can buy embroidery software from Viking that will allow you to write design files onto floppy disks, but you can find other embroidery software packages that support the D1 which cost quite a bit less - make sure that file type .sv1 is supported before you buy.
Viking does sell designs that come on a D1 floppy disk. You can just pop the floppy into the machine, select you design, and go. You can find Viking designs online from time to time, but before you buy, ask if a floppy is included - the newer Viking design packages come with a DVD but might not include the floppy for the D1.
Hope this helps, Ginny
If you have a Viking #1+, you won't be able to use floppy disks with your machine. Please repost and I'll tell you what to look for.
