Oh! MZ was published by Softbank and focused on Sharp's MZ line of computers (sold in Japan and Europe beginning in 1978). Though not a game magazine, most issues featured reviews/articles about games, and often featured game programs the user play by entering the lines of code into their computer themselves. Launched in June 1982, the magazine changed its name to Oh! X with the Nov/Dec 1987 issue due to the Sharp X1/x68000 computers supplanting the MZ series in popularity.
