Overview
The TI-84 Plus was released in 2004 as a predecessor to the TI-83 Plus. It included more RAM, ROM, and a higher clocked CPU than the TI-83 Plus. The TI-84 Plus was also the first TI-8x type calculator to be equipped with a mini USB connector along with the standard 2.5mm I/O port. An interesting note about the naming: Texas Instruments started the TI-84 family with the TI-84 Plus; there is no TI-84 non-Plus version. The TI-84 Plus was succeeded by the TI-84 Plus Color Silver Edition in 2014.
