This module is a PCB intended to be inserted in a card cage. There is an extraction handle attached to the front of the card, on which a paper label containing the model number, serial number, and other information is printed.

Opposite the handle there are 47 bifurcated gold-plated contacts arranged in two rows. Mounted on the component side of the PCB are the active and passive components, consisting mainly of transistors, diodes, resistors, capacitors, and jumpers.

There are various quality control stamps on one or both sides of the PCB.

There is a tag labeled "REPARABLE ITEM PROCESSING TAG" attached to the module with a string that contains an handwritten note "Semiconductors Good 18 Apr '74."
