The Sharp IQ-8300M — Premium IQ Organiser
The Sharp IQ-8300M was a premium model in Sharp’s IQ organiser series — one of the most capable dedicated electronic organisers Sharp produced before the company moved toward more general-purpose handheld computers. The IQ-8300M’s comprehensive feature set and expanded memory made it competitive with the best dedicated organisers of the early 1990s. Sharp’s IQ series collectively represents an important chapter in the history of portable personal information management, documenting the evolution from simple electronic address books to the full-featured PDAs that Palm and Psion would later define.
