The X68000 (Japanese: エックス ろくまんはっせん Hepburn: Ekkusu Rokuman Hassen) is a home computer created by Sharp Corporation, first released in 1987, sold only in Japan.
The first model features a 10 MHz Motorola 68000 CPU (hence the name), 1 MB of RAM, and no hard drive; the last model was released in 1993 with a 25 MHz Motorola 68030 CPU, 4 MB of RAM, and optional 80 MB SCSI hard drive. RAM in these systems is expandable to 12 MB, though most games and applications do not require more than 2 MB.
The X68k runs an operating system called Human68k which was developed for Sharp by Hudson Soft. An MS-DOS-workalike, Human68k features English-based commands very similar to those in MS-DOS; executable files have the extension .X. Versions of the OS prior to 2.0 have command line output only for common utilities like "format" and "switch", while later versions included forms-based versions of these utilities. At least three major versions of the OS were released, with several updates in between. Other operating systems available include NetBSD for X68030 and OS-9.
Early models have a GUI called "VS" or "Visual Shell"; later ones were originally packaged with SX-WINDOW. A third GUI called Ko-Windows exists with an interface similar to Motif. These GUI shells can be booted from floppy disk or the system's hard drive. Most games also boot and run from floppy disk; some are hard disk installable and others require hard disk installation.
