Burroughs Series P Adding Machine

<< >>
This full-keyboard printing electric adding machine is a relatively late desktop machine made by Burroughs Corporation. It has a tan steel frame and nine columns of tan and brown square plastic keys. To the left of these is a column of keys with abbreviations for various financial transactions. There are function bars and keys to the right of the number keys.
Above the keyboard is a two-colored ribbon and a printing mechanism, an adjustable wide carriage, and a narrow paper tape. The ribbon and its spools are covered, with screws securing the covers. Plastic knobs at the ends of the carriage are rotated to advance the platen. Next to the printing mechanism is a supplementary mechanism for setting dates. On the right side of the machine is a place for inserting a crank, although there is no crank. At the left front of the machine is a lock, with the key in it.
The machine is marked on the front: Burroughs. It has serial number on a metal tag on the back: P464325D. It is marked on another metal tag on the back: SERUES P (/) BURROUGHS CORPORATION (/) DETROIT, MICHIGAN MADE IN U.S. AMERICA.
The machine came to the Smithsonian from the Hyattsville, Maryland, branch of the Vermont Federal Savings and Loan bank.
