The Hitachi MB-H80 was the planned adaptation for the European market of the Hitachi MB-H21 in a more compact format, with more RAM (64kB instead of 32) and an 'international' QWERTY keyboard (probably with £ key).

Although announced in several magazines for release for the Christmas 1984 season[1], then delayed to Spring 1985[2], this computer has never been released.

In France, the MB-H80 was presented to the public and the press also in late 1984 but was never released.
