Burroughs Series M Bookkeeping Machine


This relatively late Burroughs bookkeeping machine has a gray metal cover. In the front are two sets of digit keys, one white and one black, as well as various functions keys. In front of these are space return, motor tab, and full cents bars, as well an an unlabeled bar. Behind the two rows of digit keys is a QWERTY keyboard with four rows of keys. Symbols indicated on some of these keys are unconventional. A lever at the right sets the machine for different registers. A wide carriage is behind the keyboard. The machine has an electric motor.

A mark on the front reads: Burroughs. A mark on a red paper tag attached to the machine reads: PATENT DEPT. (/) #212. A metal tag screwed to the front of the machine reads: A3451.

The Burroughs Series M was introduced in 1951. This example was in the collections of the Patent Division of Burroughs Corporation.
