Object is a PCB with a handle for extraction. It bears two rows of discrete transistors and other components. Printed on the component side is "CABLE DRIVER" and a copyright SDS-63. It differs from two other similar modules in that one row of transistors has been left blank, just open holes; and the resistors are green rather than light blue; and it has a 6-digit serial number rather than a 7-digit number; thus is presumably an earlier version.
