Mattel Aquarius

Released in June 1983, the Aquarius was Mattel's attempt to break into the home computer market, following the success of their Intellivision games console. Unfortunately, the Aquarius didn't sell in any great numbers and production ceased in October of the same year.

Shortly after releasing the Aquarius, Mattel announced plans for another machine, the Aquarius II (with 20Mb RAM and a full, typewriter keyboard), however it never arrived.
