Summary: The Ultimate Calculator is a modified Texas Instruments TI-83+ graphing calculator. It is an upgrade of Cemetech's Ultimate Calculator 1; the most significant changes include:
  • An improved paint job, blue with silver stripes, using Krylon spray paint and a Minwax finish.
  • A fully-functional 2.5"-diagonal PS/2 touchpad on the rear of the calculator for easy use with mouse-enabled calculator programs.
  • A higher-power TICI CSA full-spectrum RGB backlight capable of producing any color.
  • An integrated female PS/2 port for connection of a mouse, keyboard, or other PS/2 device. Current drivers support mice (and touchpads) as well as keyboards.
  • Slightly modified case construction that combines a sleeker, look with keypad and touchpad water resistance.
