Thank you, notsureif,
I did flip the top yesterday when I got it home and could see that the 2 dials with the letters probably were the combos for the various available stitches, but being unfamiliar with the machine, I didn't know how the dials/letters interacted with the builtin stitches and the cams I don't have.
Pushing that big quilt through the small harp area must have been almost impossible - I congratulate you!

I did use this one making a big quilt 7x8 ' it wasn't easy pushing the fabric, small harp area.. at times I had the needle so hot it would flex like rubber
The lady that has it now, has a 603 her cams fit the 401
had the 401 been black I would have kept it ..
