One (1) B138 module with green substrate and a blue plastic extraction handle, attached by two rivets. The handle reads "DIGITAL EQUIPMENT CORPORATION MAYNARD, MASSACHUSETTS" in raised letters. "FLIP CHIP" is printed in solder on the obverse side (with components). There are three black inspection stamps near the handle. The reverse side of substrate (with solder joints) reads "W138 " along the top-right edge. A repeating "neLco" pattern in red print is visible on the substrate.
