Founded in the 1880s, Burroughs was the oldest continuously operating entity in computing, but by the late 1950s its computing equipment was still limited to electromechanical accounting machines such as the Sensimatic; as such it had nothing to compete with its traditional rivals IBM and NCR who had started to produce larger-scale computers, or with recently founded Univac. While in 1956 it branded as the B205 a machine produced by a company it bought, its first internally developed machine, the B5000, was designed in 1961 and Burroughs sought to address its late entry in the market with the strategy of a completely different design based on the most advanced computing ideas available at the time. While the B5000 architecture is dead, it inspired the B6500 (and subsequent B6700 & B7700).
