Oh! X was dedicated to the Sharp X1 and 68000 line of computers. The magazine was a continuation of the Oh! MZ magazine, which ended with the November 1987 issue. At that time, the publisher decided that the old MZ platform was dated, and instead focused on the newer machines. Oh!X focused not only on software and hardware reviews, but also published in depth technical articles that had topics like scientific programming with lots of math, technical backgrounds of the various machines and how to use those. The writers did not shy away from high level trigonometry type math and vector calculations to 68000 machine language.
