Thank you very much for responding. If I pull up on the machine then the back board is flat like yours. In my first picture on the bottom the gap in the back, when the machine goes down it slides down a ramp type deal. I will go take a picture real quick and post it. The cable is attached to a medal bar on the backside of the front new home design that folds up when opened and it runs under the sewing machine, up the back wall and on a pulley to the door on top that opens. The machine did come with the attachments
. Thank you so much for helping me.
