The X68000 was a 16-bit personal computer announced by Sharp in 1986, and first marketed in March 1987. It was called a “personal workstation”, and attracted attention due to its sophisticated graphic capabilities, powerful AV features and distinctive “twin towers” design. It used an MC68000 CPU, was equipped standard with 1 megabyte of RAM, and had a unique sprite function and bitmapped 768x513dot display screen (65,536 colors for each dot). For sound, it was equipped with an 8 channel FM stereo sound source and an ADPCM sound source for voice synthesis. Superimposed display on a TV screen was also possible using a special-purpose display.
