If that's the case, feel free to share your favorite calculator memories in the comments. You may recognize a few as we go along, and no doubt you will see many favorites left out. In the slides ahead, let's take a look at a handful of iconic handheld calculators from the 1970s, 80s, and 90s. That trend continued into the 1980s and 90s, as simple models became nearly disposable, while higher-end units gained ever more features such as alphanumeric programmability and larger graphing displays. Each innovation brought with it corresponding reductions in cost (and increases in battery life) until a capable pocket calculator that may have cost as much as $300 in the early 1970s could be purchased for under $20 by the end of the decade. Over the years, the display technology changed from vacuum fluorescent to LED, then to LCD. In the early 1970s, integrated circuit technology finally allowed electronic calculators to shrink down to pocket size, unleashing a new era of innovation that spanned several decades.ĭuring that time, companies such as Hewlett-Packard, Texas Instruments, Casio, Sharp, and others now mostly forgotten (ever heard of Busicom, Novus, or Bowmar?) competed fiercely for their slice of the pocket calculator market - in segments from high-end scientific models to low-end consumer units. With Natural Textbook Display and an intuitive icon menu, students will find the calculator incredibly easy to use. Once upon a time, calculators were massive desktop machines - at first purely mechanical, then purely electronic. With the advanced features of a next-generation graphing calculator, the fx-CG50 PRIZM will support students and educators through middle school, high school, and into college.
