Шаблон:Infobox information appliance The B20 is a line of microcomputers from Burroughs Corporation. The systems, introduced in May 1982, consist of two models: the B21 and the B22.[1] The B21 models are rebadged Convergent Technologies AWS workstations incorporating an Intel 8086 CPU. The B22 models are rebadged IWS workstations. They run the BTOS operating system, which is a version of Convergent's CTOS, as well as CP/M and MS-DOS.[2]

Systems support up to 640 KB of RAM. The B22 included a mass storage unit with a capacity of up to 60 MB.[2]

The Burroughs B25, a rebadged Convergent NGEN system with an Intel 80186 CPU, was introduced in 1983.[3] The B26 was introduced in 1984, and a B28 system followed in 1985 based on the Intel 80286 CPU.

There is also an 80186-based B27 which used an "F-bus" rather than the "X-bus" used on the B25/B26/B28.

A cluster only (no storage) 80186-based B24 was later released and commonly used by bank tellers.
