![]() We sold 100,000."īy the time the HP-35 Scientific Calculator was discontinued in 1975, just three and one-half years after its introduction, more than 300,000 had been sold. Bill said "We're going to go ahead anyway." The product was so popular that HP couldn't make them fast enough.īill remembered, "We figured, in the first year, if we could sell 10,000 calculators, we'd break even. Sharp Junior Handheld Scientific Calculator 10 Digit Battery Power 75x10x144mm Black EL-501X 397578. They did and determined that the HP-35 Scientific Calculator would never sell because it was too expensive. When the tiny powerhouse reached the prototype stage, HP asked a local market research firm to do a market study. Bil Hewlett, who, in 1968, had challenged HP engineers to make a desktop-size computer (the 9100A), challenged them again in 1971 to take that desktop computer and make it small enough to fit into his shirt pocket. Both technologies had been developed in HP Labs. The Computer Algebra System (CAS) enables you to manipulate mathematical expressions and functions (factor, solve, differentiate, integrate) and easily evaluate mathematical expressions symbolically or numerically. The HP 35 was HP's first product that contained both integrated circuits and LEDs (light-emitting diodes). The Voyage 200 let you easily customize your handheld by adding new functions through software applications. In one of the most amazing displacements in the history of technology, the HP-35 Scientific Calculator electronic calculator, and others like it, quickly replaced the faithful slide rule that had been used by generations of engineers and scientists for rapid calculation and simple computation. It was the world's first handheld scientific calculator. 16.2 * 8 * 0.8 cm / 6.4 * 3.1 * 0.The HP-35 Scientific Calculator, so called because it had 35 keys, was introduced in 1972.
