ZX Spectrum

ZX Spectrum - 03

After the success of his two previous computers, the ZX-80 and particuraly
the ZX-81, in april 1982 Sir Clive Sinclair presents the ZX-Spectrum.
For the first time, a computer with high-resolution graphics, colors,
sound and 48k RAM was sold under 25.
Once more Sinclair revolutioned the micro computers industry with new
standards.

After the launch of the Spectrum, many other micro-computer manufacturers
were forced to reduce their prices, and 17 months after the release of the
Spectrum, the sales already reached 1 million units !

The critics first saw the ZX Spectrum has an enhancement of the ZX-81,
but it is much more ! 


The Sinclair Spectrum was one of the most popular European computers
of the 80's.
Two models were launched: one with 16 kb RAM and one with 48 kb ram. 

One of its most "interesting" characteristics is its keyboard!
Some keys have more than five (!) functions! It is impossible to type BASIC
keywords letter by letter but you have to use functions keys.
A lot of peripherals and programs were developed for this computer.
It seems that several models of this computers were launched (at least 3),
but I've no technical details about them.
It was replaced in 1984 by the Spectrum +, then by the Spectrum 128.
