Texas Instruments TI-83 Graphing Calculator, Original Design - Black

Type Graphing calculator Manufacturer Texas Instruments Introduced 1996 Discontinued 2004 Predecessor TI-82 Successor TI-83 Plus Entry mode D.A.L. Processor Zilog Z80 Frequency 6 MHz Programming language(s) TI-BASIC, Assembly User memory 32 kB RAM Power supply 4 AAAs, 1 CR1616 or CR1620 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.
