Burroughs Series P Adding Machine

<< >>
This full-keyboard printing electric adding machine has a black metal case, black and white color-coded round plastic keys, a rubber carriage, rubber feet, and a metal paper tape holder at the back. There is a hole for a handle but no handle. There are ten columns of keys, with nine keys in each column, as well as a column with five function keys and a large “+” bar.
A red paper tag attached to the machine reads: PATENT DEPT. (/) #208. A metal tag attached to the keyboard reads: 139-243. The machine is marked on the front: Burroughs. A white paper tag attached to the object reads: STY 10 (/) TALLY ROLL (/) MACH (/) TAG (/) 139-243. A metal tag attached to the object reads: DONATED TO (/) The Smithsonian Institution (/) by (/) Burroughs Corporation.
This example was #208 in the collection of the Patent Division of Burroughs Corporation. The Burroughs Series P was introduced in 1949, and this machine presumably dates from about that time.
