The initial model has a 10 [[Megahertz|MHz]] [[Motorola 68000]] [[Central processing unit|CPU]], 1 [[Megabytes|MB]] of [[Random Access Memory|RAM]], and lacks a [[Hard disk|hard drive]]. The final 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 X68000 has graphics hardware similar to [[arcade video game]]s of the late-1980s, with custom coprocessors supporting scrolling, tiled backgrounds, and large numbers of [[sprite (computer graphics)|sprite]]s. Sound is supplied through multiple sound chips supporting 8 channels of [[FM synthesis]] and one channel of [[adaptive differential pulse-code modulation]] audio, which are mixed down to 2 analog stereo channels via a [[Digital-to-analog converter|DAC]] chip. As such, [[Video game|video gaming]] was a major use of the X68000. |

||
The X68k runs an [[operating system]] called Human68k which was developed for Sharp by [[Hudson Soft]]. An [[MS-DOS]]-workalike, Human68k features [[English language|English]]-based commands very similar to those in [[MS-DOS]]; executable files have the extension <code>.X</code>. Versions of the OS prior to 2.0 have command line output only for common utilities like "format" and "switch", while later versions included [[Text-based user interface|forms-based]] versions of these utilities. At least three major versions of the OS were released, with several updates in between. |

Early models have a [[GUI]] called "VS" or "Visual Shell"; later ones were originally packaged with [[SX-WINDOW]]. A third GUI called Ko-Window exists with an interface similar to [[Motif (software)|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. |

The X68000 |
The X68000 has two soft-eject 5.25-inch floppy drives, or in the compact models, two 3.5-inch floppy drives, and a very distinctive case design of two connected [[Computer tower|tower]]s, divided by a retractable carrying handle. This system was also one of the first with a software-controlled power switch; pressing it signals the system's software to save and shut down. The screen fades to black and the sound fades to silence before the system turns off. |
||
The system's keyboard has a mouse port built into either side. The front of the computer has a headphone jack, volume control, joystick, keyboard and mouse ports. The top has a retractable carrying handle only on non-Compact models, a reset button, and a [[non-maskable interrupt]] (NMI) button. The rear has a variety of ports, including stereoscopic output for 3D goggles, FDD and HDD expansion ports, and I/O board expansion slots. |

[[Human68K]] does not support the [[VFAT long filename]]s standard of modern Windows systems, but it supports [[18.3 filename|18.3]] character filenames instead of the [[8.3 filename|8.3]] character filenames allowed in the [[FAT filesystem]]. Human68K is case sensitive and allows lower case and [[Shift JIS]] encoded [[Kanji]] characters in filenames, both of which cause serious problems when a DOS system tries to read such a directory. If a X68000 user restricts themselves to use only filenames according to the 8.3 characters scheme of DOS, using only Latin upper case characters, then a disk written on the X68000 is fully compatible with other Japanese standard platforms like e.g. the [[NEC PC-9800]], the [[Fujitsu FMR]] and [[FM Towns]] computers. The Japanese standard [[List of floppy disk formats|disk format]] used by the X68000 is: 77 tracks, 2 heads, 8 sectors, 1024 bytes per sector, 360 rpm (1232 KiB). |
[[Human68K]] does not support the [[VFAT long filename]]s standard of modern Windows systems, but it supports [[18.3 filename|18.3]] character filenames instead of the [[8.3 filename|8.3]] character filenames allowed in the [[FAT filesystem]]. By default, Human68K will not consider any additional characters beyond the first 8 without the use of a special driver, therefore files and folders that are named the same when viewed through a 8.3 filename but different when viewed through a 18.3 filename will be considered the same.

Many add-on cards were released for the system, including networking (Neptune-X), SCSI, memory upgrades, CPU enhancements (JUPITER-X 68040/060 accelerator), and [[MIDI]] I/O boards. The system has two joystick ports, both 9-pin male and supporting [[Atari joystick port|Atari standard joysticks]] and [[MSX]] controllers. Capcom produced a converter that was originally sold packaged with the X68000 version of ''[[Street Fighter II]]'' that allowed users to plug in a [[Super Nintendo Entertainment System|Super Famicom]] or [[Mega Drive]] controller into the system. The adapter was made specifically so that users could plug in the Capcom Power Stick Fighter controller into the system. |

In terms of [[Computer hardware|hardware]], the X68K was very similar to [[arcade system board|arcade machines]] of the time, and served as the Capcom [[CP System|CPS]] system development machine. It supports separate text RAM, graphic RAM and hardware sprites. Sound is produced internally via Yamaha's then top-of-the-line [[Yamaha YM2151|YM2151]] FM synthesizer and a single channel OKI MSM6258V for [[Pulse-code modulation|PCM]]. Due to this and other similarities, it played host to many [[arcade game]] [[porting|ports]] in its day. Games made for this system include ''[[Parodius Da! -Shinwa kara Owarai e-]]'', ''[[Ghouls 'n Ghosts]]'', ''[[Strider (arcade game)|Strider]]'', ''[[Final Fight (video game)|Final Fight]]'', ''[[Alien Syndrome]]'', ''[[Street Fighter II: Champion Edition]]'', ''Akumajo Dracula'' (''Castlevania'' in other regions, the X68000 version was ported to the [[PlayStation]] as ''[[Castlevania Chronicles]]''), ''[[Cho Ren Sha 68k]]'' (which has a Windows port) and many others. Many games also supported the [[Roland Corporation|Roland]] [[Roland SC-55|SC-55]] and [[Roland MT-32|MT-32]] MIDI modules for sound as well as mixed-mode internal/external output. |

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. It was first released in 1987 and sold only in Japan.
The initial model has a 10 MHz Motorola 68000 CPU, 1 MB of RAM, and lacks a hard drive. The final 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 X68000 has graphics hardware similar to arcade video games of the late-1980s, with custom coprocessors supporting scrolling, tiled backgrounds, and large numbers of sprites. Sound is supplied through multiple sound chips supporting 8 channels of FM synthesis and one channel of adaptive differential pulse-code modulation audio, which are mixed down to 2 analog stereo channels via a DAC chip. As such, video gaming was a major use of the X68000.
Operating system
[edit]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.
Early models have a GUI called "VS" or "Visual Shell"; later ones were originally packaged with SX-WINDOW. A third GUI called Ko-Window 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.
Since the system's release, software such as Human68k itself, console, SX-Window C compiler suites, and BIOS ROMs have been released as public domain software and are freely available for download.[2] Other operating systems available include OS-9 and NetBSD for X68030.[3][4]
Case design
[edit]The X68000 has two soft-eject 5.25-inch floppy drives, or in the compact models, two 3.5-inch floppy drives, and a very distinctive case design of two connected towers, divided by a retractable carrying handle. This system was also one of the first with a software-controlled power switch; pressing it signals the system's software to save and shut down. The screen fades to black and the sound fades to silence before the system turns off.
The system's keyboard has a mouse port built into either side. The front of the computer has a headphone jack, volume control, joystick, keyboard and mouse ports. The top has a retractable carrying handle only on non-Compact models, a reset button, and a non-maskable interrupt (NMI) button. The rear has a variety of ports, including stereoscopic output for 3D goggles, FDD and HDD expansion ports, and I/O board expansion slots.
Display
[edit]The monitor supports horizontal scanning rates of 15, 24, and 31 kHz and functions as a cable-ready television (NTSC-J standard) with composite video input. It was a high quality monitor for playing JAMMA-compatible arcade boards due to its analog RGB input and support for all three horizontal scanning rates used with arcade games.
Disk I/O
[edit]Early machines use the rare Shugart Associates System Interface (SASI) for the hard disk interface; later versions adopted the industry-standard Small Computer System Interface (SCSI). Per the hardware's capability, formatted SASI drives can be 10, 20 or 40 MB in size and can be logically partitioned as well.
Human68K does not support the VFAT long filenames standard of modern Windows systems, but it supports 18.3 character filenames instead of the 8.3 character filenames allowed in the FAT filesystem. By default, Human68K will not consider any additional characters beyond the first 8 without the use of a special driver, therefore files and folders that are named the same when viewed through a 8.3 filename but different when viewed through a 18.3 filename will be considered the same. Human68K is case sensitive and allows lower case and Shift JIS encoded Kanji characters in filenames, both of which cause serious problems when a DOS system tries to read such a directory. If a X68000 user restricts themselves to use only filenames according to the 8.3 characters scheme of DOS, using only Latin upper case characters, then a disk written on the X68000 is fully compatible with other Japanese standard platforms like e.g. the NEC PC-9800, the Fujitsu FMR and FM Towns computers. The Japanese standard disk format used by the X68000 is: 77 tracks, 2 heads, 8 sectors, 1024 bytes per sector, 360 rpm (1232 KiB).
Expansion
[edit]Many add-on cards were released for the system, including networking (Neptune-X), SCSI, memory upgrades, CPU enhancements (JUPITER-X 68040/060 accelerator), and MIDI I/O boards. The system has two joystick ports, both 9-pin male and supporting Atari standard joysticks and MSX controllers. Capcom produced a converter that was originally sold packaged with the X68000 version of Street Fighter II that allowed users to plug in a Super Famicom or Mega Drive controller into the system. The adapter was made specifically so that users could plug in the Capcom Power Stick Fighter controller into the system.
