And yes, TI calculators have indeed been improving, apparently.
The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the TI-84 features improved hardware. The archive (ROM) is about 3 times as large, and the CPU is about 2.5 times as fast (over the TI-83 and TI-83 Plus)[citation needed]. A USB port and built-in clock functionality were also added. The USB port on the TI-84 Plus series is USB On-The-Go compliant, similar to the next generation TI-Nspire calculator, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the serial link port.
Do kids still use these? Aka, are their parents forced to pay $100 bucks for this piece of 40 year old technology?
They’re passed down as heirlooms now, like slide rules before them.
fun fact: there are graphing calculator emulators, even modern tinspire cx and cx2 models can be emulated (firebird emu) (as well as ti 83/84 etc, although obviously a different emulator is used for those models)
Schools own them a lot of the time
They aren’t allowed anymore where I live. Only basic calculators now
Here I think using GeoGebra is the norm now for graphing needs.
Desmos is it where I am.
