Of course NOW I have a 500A and a 503A so I can buy for those machines :).
The attachments move the fabric, the needle does not move. You do need a plate to cover the feed, that is what a T-plate does. Singer made a Zig-Zag attachment for a straight stitch machine at one time that works the same way - it moves the fabric back and forth.
