The Datamath Calculator Museum received this PLT IRDA Infrared Communication Card together with some unique graphing calculators as a loan from Texas Instruments in February 2008 to photograph and document it.

The Dallas, TX based team nicknamed it PET Project including three advanced graphing calculators:

PLT SHH1: Spot Hand Held, first generation PET device with smaller, portrait oriented screen.
PLT FHH1: Fido Hand Held, first generation PET device with larger, landscape oriented screen
PLT SU1: Toto Hand Held, second generation PET device with large, color screen.

This PLT IRDA Wireless Infrared Communication Card was developed for the PLT SU1 to establish a wireless connection to the outside world according to the Infrared Data Association (IrDA) standard. IrDA was popular on laptops during the late 90s and early 2000s but was replaced by other wireless technologies such as WiFi (IEEE 802.11b) and Bluetooth.
