The TI-83 series of graphing calculators is manufactured by Texas Instruments. The original TI-83 is itself an upgraded version of the TI-82. Released in 1996, it was one of the most popular graphing calculators for students. In addition to the functions present on normal scientific calculators, the TI-83 includes many features, including function graphing, polar/parametric/sequence graphing modes, statistics, trigonometric, and algebraic functions, along with many useful applications. Although it does not include as many calculus functions, applications (for the TI-83 Plus—see below) and programs can be downloaded from certain websites, or written on the calculator.
TI replaced the TI-83 with the TI-83 Plus calculator in 1999, which included flash memory, enabling the device's operating system to be updated if needed, or for large new Flash Applications to be stored, accessible through a new Apps key. The Flash memory can also be used to store user programs and data. In 2001, the TI-83 Plus Silver Edition was released, which featured approximately nine times the available Flash memory, and over twice the processing speed (15 MHz) of a standard TI-83 Plus, all in a translucent grey case inlaid with small "sparkles".
The TI-83 was redesigned twice, first in 1999 and again in 2001. The 1999 redesign introduced a design very similar to the TI-73 and TI-83 Plus, eliminating the sloped screen that had been common on TI graphing calculators since the TI-81. The 2001 redesign (nicknamed the TI-83 "Parcus") introduced a slightly different shape to the calculator itself, eliminated the glossy grey screen border, and reduced cost by streamlining the printed circuit board to four units.
The TI-83 was the first calculator in the TI series to have built in assembly language support. The TI-92, TI-85, and TI-82 were capable of running assembly language programs, but only after sending a specially constructed (hacked) memory backup. The support on the TI-83 could be accessed through a hidden feature of the calculator. Users would write their assembly (ASM) program on their computer, assemble it, and send it to their calculator as a program. The user would then execute the command "Send (9prgmXXX" (where XXX is the name of the program), and it would execute the program. Successors of the TI-83 replaced the Send() backdoor with a less-hidden Asm() command.
