The Museum of HP Calculators


The calculator that wouldn't die. The HP-12C is HP's longest and bestselling calculator. Though it has been followed by many newer models, with both more and less features this model continues to sell well. In fact, an EduCALC catalog says of the HP 17BII (in bold type): "It's 15 times faster than the HP 12C, and displays more than 4 times as much information." And of the HP 19BII: "It's 15 times faster than the HP 12C, and displays more than 9 times as much information." In addition, both newer calculators can print via infrared to compact printers, have more memory, general purpose solvers, menus etc.
