One (1) R181 module with green substrate and a red plastic extraction handle attached by two rivets. The handle reads "DIGITAL EQUIPMENT CORPORATION MAYNARD, MASSACHUSETTS" in raised letters and "018" is incised between "CORPORATION" and "MAYNARD." The substrate on the solder-side reads "DC CARRY CHAIN R181C" along the edge. There are three black, circular inspection stamps near the handle on the component-side between the rivets. A repeating "neLco" pattern in red print is visible on the substrate.
