The 48K Spectrum was THE computer for tens of
thousands of teenagers in the 1980s. Apart from
the increased memory, this version was indistinguishable
from the 16K model.
Owners of the short-lived 16K version could have
them upgraded to 48KB.
A huge amount of games software was produced while
computer magazines and books published more for
the enthusiast to type in. Despite criticism for
its limited colour and poor sound, the Spectrum
was the most successful British computer by a long
way. It was so popular that where people could not
buy one in the Soviet Union and communist Eastern
Europe, they simply set up factories to make their
own!
