The TI-85 was a graphing calculator released by Texas Instruments in the early 1990s. It was designed primarily for engineering and calculus students, featuring advanced functions that set it apart from other calculators of its time, such as the TI-83. The TI-85 included capabilities for complex number calculations, vector arithmetic, and matrix operations, making it a powerful tool for higher-level math and science courses.

I got my TI-85 in high school when most of my classmates were using the TI-83. The TI-85’s advanced features and programmability allowed me to write custom programs, some of which are still available online today.
