About this document

TI-59 Firmware Analysis and Functions by Alejandro Menéndez is a document available to read on EtoBox.

The document summarizes the firmware of the TI-59 calculator by examining the program code that can be observed through an unusual keyboard sequence. Key points include: 1) The code mechanizes statistics, conversion, and transcendental functions through manipulation of hierarchy registers and by utilizing embedded constants equivalent to values like π, π/2, and the natural logarithm of 2. 2) Repeating sections of code were discovered, and constants were identified that could be used for trigonometric fun
