About the Texas Instruments TI-84 Plus

Texas Instruments introduced the TI-84 Plus in 2004 as a faster successor to the TI-83 Plus. It has a monochrome screen and runs on four AAA batteries plus a small backup cell. Check the screen for dead lines or faded contrast, the battery compartment for corrosion, and whether the slide cover is included.

What affects the price

  • Screen: no dead rows or faded segments.
  • The slide cover, charging/USB cable and battery (rechargeable models).
  • Engravings from schools and exam-mode lights are common and lower the price a little.
