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!
