A rare and advanced Sharp EL-9900G scientific graphic calculator, released in 2005 as part of Sharp’s high-end global series. Designed for students and professionals in mathematics, physics, and engineering, this model features a dot-matrix LCD display (132×64 pixels), an equation editor with textbook-style input, graph plotting capabilities, statistical and matrix functions, and a dual-function keyboard layout for both basic and advanced operations. The calculator is fully functional. All main functions operate correctly. Please note: two vertical lines on the display do not show, as visible in the photos. This minor display issue does not affect general usability. The exterior shows light wear consistent with normal use and age. Comes as shown in the photos. Batteries are not included. An excellent opportunity to acquire a working example of the Sharp EL-9900G — a powerful and increasingly rare graphic calculator, appreciated by both collectors and enthusiasts of vintage scientific instruments.
