As the German magazine "mc" reported in its January 1981 first edition, the MZ-80B was shown first on the German Hannover show, in April 1981.

The MZ-80B was one of the nicer, if not the nicer, and well designed home computer ever built. It also featured an innovative 'Intelligent' cassette deck which was able to find and load a program anywhere in the cassette tape. All the cassette functions were remote controlled by software.

The MZ-80B was compatible with the other MZ 80x computers (Sharp MZ 80A, Sharp MZ 80K), but unlike these ones, it was possible to have high graphic resolution thanks to one or two optional boards which provided one or two switchable graphic pages.

This computer, like all the computers of the Sharp MZ series, had no language in ROM, Basic (or any other language) had to be loaded from tape.
