The Sharp X1 was first released in Japan on January 11, 1982. Alongside the FM-7 and the NEC PC-8801, it was considered one of the "big 3" of Japanese personal computers in the 1980s. The X1 was Sharp's successor to the Sharp MZ, released in 1978, and it was in turn succeeded by the powerful Sharp X68000 computer in 1987.
