The Archive’s “Calculator Drawer” – as it has named the collection – includes classic machines from Texas Instruments’ graphing calculator series. You’ll find the TI 73 Explorer, 81, 82, 83 Plus, 85, 86, and – the holy grail – the 89. All of these became ubiquitous because they were allowed into college entrance exams and various standardized tests. Many a calculator that started life in that role ended up in a university student’s backpack and – failing theft or misplacement – eventually landed in the engineer’s work drawer.
The renditions of the user interfaces are not only accurate, but also in some cases – like the HP 48G+ and Vtech Number Muncher – include sound.
