ZX SPECTRUM 48K VERSIONS AND CLONES AROUND THE WORLD
(pictures come from Internet, mostly from www.old-computers.com and www.homecomputer.de cool sites - You should visit them too :) )
To be precise, ZX48K was a best-seller not only in the first 80s half. It was a home-computers' best-seller ever because Sinclair Research wasn't the only company selling the machine. Oh, not at all. Spectrum 48 was the most popular machine to clone it, in many many countries.
There are following versions of this machine:
Of course the main version - The Rubber.
