Acorn BBC Master
The BBC Master is a home computer released in early 1986 by Acorn Computers Ltd.
The computer was developed and built under the auspices of the British Broadcasting Corporation (BBC) and is the successor to the BBC Micro Model B.
The Master 128 remained in production until 1993. There was also the Master 512 with a 10 MHz Intel 80186 coprocessor and 512 kB of memory and a smaller Master Compact.
The computer is used for the BBC's Domesday Project around the 1980s.
