The Sharp IQ-7100M — Enhanced Electronic Organiser
The Sharp IQ-7100M was an enhanced model in Sharp’s IQ electronic organiser series — offering improved memory and features over the base IQ-7000. Sharp’s IQ series evolved steadily throughout the late 1980s and early 1990s, with each successive model offering expanded storage and additional functions as the technology became more capable and affordable. The IQ-7100M’s enhanced capabilities made it a more practical tool for serious organisational needs, bridging the gap between simple phone/address books and the more capable handheld computers that would follow.
