Object is in a small wooden cabinet, on top of which are a typebar typewriter (looks like an IBM Executive but not so labelled) and a 10-key adding machine console, both seated in shaped cutouts in the top. The adding machine has a number of pilot lights and function knobs and keys. Inside the cabinet at the rear is a metal frame containing an array of sealed circuit modules and a bank of printed circuit boards with discrete transistor logic. Inside the cabinet at the front left is a frame for a programming plugboard.
