A large aluminum memory drum mounted on a wooden stand. The instrument includes two scrolls. There are two large black knobs labelled T-1 and T-2 with a gradient from .5 to 6 on the left of the “operators” side. There are three metal switches on the right of the “operators” side labelled “Paired Assoc/Serial”, “Oper./St’by”, and “On/Power”. The drum rotates on the operator’s side at a speed set by the operator. There is a large metal plate on the back of the drum that shields the drum from the test subject. There is a horizontal slit window in the shield that exposes the scroll on the drum to the test subject on the other side one line at a time, at a speed determined by the operator. A black power cable is attached to the operator’s side.
