Acorn BBC

The Acorn BBC became popular in a british computer-series which has
been shown on BBC. The BBC did not succeed in many other parts in
the world but defended its high popularity in the U.K. against the
C64 and Spectrum. One advantage of the BBC was his expansion ability:
You could even add a second CPU to run CP/M. There were also many
derivations of the BBC like the BBC Master.
The first model, BBC model A, was limited by 16 KB of RAM.
Since RAM was shared between user programs and video memory,
the more colorful graphics modes were severely limited.
However, the teletext mode became quite poopular because of
its speed, low footprint, and suitability for serious (text
based) applications. The BBC model B doubled the amount of
RAM, and became the de facto educational machine - especially
when combined with a diskette drive and Acorn's proprietary
Econet network. Software and data could be loaded from tape,
diskettes, ROM chips, the network or Winchester drives. ROMs
could be mapped in and out of the language ROM area as they
were needed.
