This is a logic module with a light green board and a raised black metal edge. Various components cover the entire board, and are divided into seven rows by yellow metal rails. There is one square inspection stamp in the top right corner, which reads "444". On the circuit side there are several green wires, which are glued in place. At the removal end, the black edge is held in place by five rivets.
