The 2001 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.

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 2001 redesign (nicknamed the TI-83 "Parcus"[2]) 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 main improvement over the TI-83, however, is the addition of 512 KB of Flash ROM, which allows for operating system upgrades and applications to be installed.

Another development is the ability to install Flash Applications, which allows the user to add functionality to the calculator.

Its enhancements are 1.5 MB of flash memory, a dual-speed 6/15 MHz processor, 96 KB of additional RAM (but TI has yet to code support for the entire RAM into an OS), an improved link transfer hardware, a translucent silver case, and more applications preinstalled.

It is virtually identical, but has an additional port at the screen end of the rear of the unit, enabling displays on overhead projectors via a cable and panel.

TI-BASIC is a non-structured programming language, meaning it is arranged sequentially, without the use of methods or organized blocks of code.

Due to its simplicity and the ubiquity of TI calculators in school curricula, for many students it is their first experience with programming[citation needed].

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.

[5] In 2009, a group of enthusiasts used brute force and distributed methods to find all of the cryptographic signing keys for the TI calculator firmware, allowing users to directly flash their own operating systems to the devices.

[7] Texas Instruments then began sending out DMCA take-down requests to a variety of different websites mirroring the keys, including unitedTI and reddit.com.

The TI-84 Plus also has a brighter screen with a clearer contrast, though this caused a bug with the LCD driver in some calculators sold.

The operating system and math functionality remain essentially the same, as does the standard link port for connecting with the rest of the TI calculator series.

Furthermore, textbooks have been tailored for the TI-83 effectively giving the calculator a "monopoly in the field of high school mathematics.
