Two (2) M121B modules with green board and a magenta plastic extraction handle attached by two rivets. The handle reads "digital" in raised letters on the solder-side. The board on the solder-side reads "XOR GATE M121B" along the left-edge. "FLIP CHIP" is printed between the rivets on the component-side. There are three black inspection stamps on the component-side; one circle, one triangle, and one square. A repeating "Tc" pattern is printed on the board in red.
