W994 module with green substrate and a tan plastic extraction handle, attached by two rivets. Handle reads "DIGITAL EQUIPMENT CORPORATION MAYNARD, MASSACHUSETTS" in raised letters. Reverse side of substrate (with solder joints) reads "3-66 PERFORATED BOARD W994A" along the edge. Obverse side has three identical components. "FLIP CHIP" can be read through substrate, beneath inspection stamps, between the rivets. A repeating "NP" pattern in red print is visible on the substrate.
