The Sharp IQ-7300M — Advanced IQ Organiser
The Sharp IQ-7300M was an advanced model in Sharp’s IQ organiser series, offering expanded memory and enhanced organisational features. By the early 1990s, Sharp’s IQ series had evolved into genuinely capable personal information management devices that rivalled dedicated PDAs for basic organisational tasks. The IQ-7300M’s combination of address book, scheduler, expense tracker, and memo functions in a compact device represented the mature development of the dedicated electronic organiser concept before Palm OS-based PDAs redefined expectations for handheld computing.
