While not every calculator from the past 25 years is part of the collection, if you used a Texas Instruments or HP model in school, you may find something familiar. The Internet Archive has also uploaded manuals for most of the included calculators, so even if you feel overwhelmed by all the buttons, you can easily refresh your memory. So whether you want to relive the past or just want to explore a piece of technology history, the Internet Archive’s Calculator Drawer is a fun and educational tool.
