Sharp X68000 PRO II

The Sharp X68000 PRO II updated the horizontal, expansion-focused branch of the X68000 family in April 1990. It retained four expansion slots and the 10 MHz 68000-class processor while adding the contemporary Human68k and SX-Window software environment.

Floppy-only and PRO II-HD configurations were available, with the latter incorporating a 40MB hard disk for professional and creative applications.

Notable Features

• Horizontal desktop enclosure with four expansion slots.
• PRO II-HD configuration included a 40MB hard disk.
• Updated Human68k and SX-Window software.

Historical Significance

• Continued the most expandable branch of Sharp’s X68000 range.
• Well suited to MIDI, graphics and development hardware installations.

Collector's Notes

• Expansion cards can make individual PRO II systems unusually configured.
• Inspect the internal battery and power supply before operation.
