Burroughs B20

The B20 was a line of microcomputers from Burroughs Corporation. The systems, introduced in 1982, consist of two models: the B21 and the B22. The B20 computers were rebadged Convergent Technologies AWS workstations incorporating an Intel 8086 CPU. They ran the BTOS operating system, which was a version of Convergent's CTOS, as well as CP/M and MS-DOS.
Systems supported up to 640 KB of RAM. The B22 included a mass storage unit with a capacity of up to 60 MB.
The Burroughs B25, a rebadged Convergent NGEN system with an Intel 80186 CPU, was introduced in 1983. The B26 was introduced in 1984, and a B28 system followed based on the Intel 80286 CPU.
