The BBC Master Series was introduced by Acorn in 1986 as a range of 8-bit machines to succeed the earlier BBC Microcomputers. There is more information on the machines in the range by following the links above.
In addition to the machines above, a Master Scientific was planned with an internal 32016 co-processor. As far as I know, this never came to fruition.
