ti-84

     

The TI-84 Plus is a graphing calculator mae by Texas Instruments that came out in the spring of 2004. There is no original TI-84, only the TI-84 Plus and TI-84 Plus Silver Edition models. It is an enhanced version of the TI-83 Plus. The key-by-key correspondence is the same, but the 84 features improved hardware. The memory is about 3 times as large, and CPU about 2.5 times faster (over the TI-83 and TI-83 Plus). A USB port and built-in clock functionality were also added. The clock can be used to tell the time since the RAM last cleared (if set correctly, it will tell the actual time). It is merely a slightly enhanced version of the TI-83 Plus Silver Edition, as it retains many of the same system specs. 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 the via Link port. Although graphing calculators have been called inexpensive in education reform research, the TI-84 Plus Silver Edition was $129.99 in 2008 on the TI online store.
