Definition
Sharp X68000 (X68K) refers to a line of computers developed by Sharp Corporation starting in 1987. The X68K line uses the Motorola 68000 family of processors and typically run the Human68k operating system. The majority of software was released on floppy disks, however a limited number of CD-ROMs (and a couple DVD-ROMs) were released. Redump.info only handles the CD-ROM/DVD-ROM software, whereas the floppy disks are handled by other projects such as TOSEC and No-Intro.
General Notes
IBM PC / Sharp x68k hybrids get added to IBM PC unless the content is not game related. Then it gets added to x68k.
