DescriptionObject is a basic 026 keypunch with the usual card feed mechanism, printing head, control drum, and keyboard with four switches. In addition it has a plugboard that mounts in the lower left side. On the rear right corner is a toggle switch (clearly a local modification) with handwritten labels of "Routine Counting System" for the up position and "PDP-8 + Card Punch" for the down position.
Found inside the left side of the machine were a wiring diagram, a Field Engineering Maintenance manual, and a Type 526 Parts Catalog (sent to archives).
