Usage conditions apply
This direct multiplication, printing, electric billing machine comes from the collection of the Burroughs Adding Machine Company Patent Department.
The machine has a metal frame painted black. At the front are two rows of keys that control the computing mechanism. The machine has only one set of digit keys. These keys are of white or brightly colored plastic. Behind these two rows of keys are four rows of typewriter keys used to type descriptions and other information. These keys appear to have metal stems and edges, with plastic tops. The “uppercase” keys are not conventional uppercase letters. A wide carriage is above and behind the keyboards, and further mechanism behind it. The machine has a motor below, and a box of parts is crated with it.
The machine is marked on a red paper tag attached to it: PATENT DEPT. (/) #28. It is marked on the case above the keyboard and at the back: Burroughs.
Compare Burroughs Moon-Hopkins billing machine. This machine is not identical to it or to 1982.0794.37.
