TI-60X_Back.jpg (223632 Byte)The TI-60X Advanced Scientific calculator carries the name of the slanted TI-60 but uses the housing and keyboard technology of a TI-68. The overall appearance and the simple formula programming gives this calculator the nickname "TI-68 light". 

The most obvious difference is the bold-looking display, a deeper exploration reveals a character layout of only 5*4 dots instead the common 7*5 dot matrix.

The internal construction of the TI-60X is identical with the TI-68. A powerful Toshiba 4-bit single-chip microcontroller T9838 (TI-68: Toshiba T9948A) assembled on a rigid two-sided printed circuit board and the dot-matrix LC-display attached with a flexible cable.

The TI-60X is one of the early calculators using the EOS or Equation Operating System compared to the original AOS system developed with the SR-52. The TI-60X lets you enter an expression into the entry line the same way as you would write it. You can move through the entry line to review or edit any part of the expression before evaluating it. Most of the information about entering and editing applies both to equations and formulas. The maximum length of an equation can range from 71 to 236 characters, depending of the amount of data (such as variables and formulas) you have stored. Each digit occupies one character and each operation occupies two characters.
