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 OS, 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.
