Sharp MZ-2000

The Sharp MZ-2000 was a Japanese business and technical computer introduced in June 1982 as the successor to the MZ-80B. It retained the integrated monitor and cassette-drive layout while providing a 4 MHz Z80A-compatible processor and 64KB of RAM.

Its stronger display hardware and expansion options made it suitable for professional software, and Sharp later offered a 16-bit expansion board to extend performance and memory.

Notable Features

• 4 MHz Z80A-compatible processor and 64KB RAM.
• Integrated monitor and software-controlled cassette recorder.
• Optional 16-bit expansion board became available in 1984.

Historical Significance

• Continued the professional MZ-80B branch in Japan.
• Provided the architectural foundation for the modular MZ-2200 and later Super MZ.

Collector's Notes

• The MZ-2000 was not generally exported to Europe.
• Expansion hardware and original Japanese software are difficult to find.
