The Sharp X68000 was a Japanese personal computer produced between 1987 and 1993. Commonly known as the X68k, it came in a striking double-tower case and was a highly advanced machine for its time.
Unlike its main competitor, the PC-98
, the X68000 was designed to be as much of a gaming machine as a business machine; the original model came bundled with Gradius
The X68000 was one the most powerful and expensive 16-bit home video game systems
, considerably superior to the Sega Genesis
, and rivaling even the arcade-quality Neo Geo
console (later X68000 models helped out in the graphics department and added an eight-channel PCM chip into the mix, yet the latter was mainly an add-on). Capcom
made it the prototype and the basis for its SDK unit for its CP System (CPS) arcade board, and many of the X68000's releases were Arcade Perfect Ports
. In fact, former Capcom composer/sound programmer Hiroaki Kondo is credited as "X68K" in the games he worked on.
It sold 16 million units, making it the third best-selling Pre-Windows 95
computer of all time, right behind the PC-98 (18 million units) and the Commodore 64
(17 million units).
