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 six rows by yellow metal rails. There is one square inspection stamp in the top right corner, which reads "140". On the solder side there are two small black inspection stamps situated near the middle. At the top the black edge is held in place by five rivets.
