Burroughs

The Burroughs Corporation was a major American manufacturer of business equipment. The company was founded in 1886 as the American Arithmometer Company and was assimilated in the 1986 merger that resulted in the creation of Unisys. The company's history paralleled many of the major developments in computing. At its start it produced mechanical adding machines, and later moved into programmable ledgers and then computers. And while it was one of the largest producers of mainframe computers in the world, Burroughs also produced related equipment as well, including typewriters and printers.
