The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the aforementioned, but the 84 features some improved hardware. The archive (ROM) is nearly three times as large, and CPU about ii.5 times every bit fast (over the TI-83 and TI-83 Plus). A USB port and born clock functionality were also added. The USB port on the TI-84 Plus series is USB On-The-Become compliant, like to the next generation TI-Nspire figurer, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the series link port.[i]
Versions [edit]
TI-84 Plus Silver Edition [edit]
The TI-84 Plus Silver Edition was released in 2004 as an upgrade to the TI-83 Plus. Like the TI-83 Plus Silver Edition, information technology features a 15 MHz Zilog Z80 processor and 24 kB user available RAM. The chip has 128 kB, but Texas Instruments has non made an OS that uses all of it. Newer calculators have a RAM bit that is only 48 kB. All calculators with the letter H or later equally the last letter of the alphabet in the series code have fewer RAM pages, causing some programs to not run correctly.[two] There is ane.5 MB of user-attainable Flash ROM. Like the standard TI-84 Plus, the Argent Edition includes a built-in USB port, a built-in clock, and assembly support. It uses four AAA batteries and a backup button cell battery. The TI-84 Plus Silver Edition comes preloaded with a variety of applications. These programs are also available for the TI-84 Plus, but some must be downloaded separately from TI'due south website. It is manufactured by Kinpo Electronics.
TI offers a special yellowish version of the TI-84 Plus, inscribed with the words "School Property", for schools to loan out to students. This special pattern was produced in an effort to gainsay theft.[3] Owners tin can purchase other interchangeable colored face-plates and slide-cases online. A kickstand-style slide instance and other accessories are likewise available. Although graphing calculators take been called inexpensive in education reform research,[four] the TI-84 Plus Silverish Edition cost $139.00 as of 2013 on the TI online store, just this computer has been discontinued in favor of the TI-84 Plus C Silver Edition.
In 2011, TI launched the TI-84 Pocket.fr, a miniaturized version of the TI-84 Plus for the French market place.[5] In 2012, TI launched the TI-84 Plus Pocket SE, a miniaturized version of the TI-84 Plus Silver Edition for the Asian market place.[6]
In 2015, Texas Instruments released the TI-84 Plus T in the Netherlands. This model is very like to the original TI-84 Plus, but features an LED to indicate whether or not the computer is in Exam Mode. The hardware of the TI-84 Plus T is similar to the TI-84 Plus Silver Edition, with 96 16 kB pages of archive memory, for a total of 1540 kB. Even so, unlike the TI-84 Plus, the TI-84 Plus T does not allow users to execute assembly programs. The TI-84 Plus T has 2 unlike Exam Modes bachelor with different levels of restrictiveness. The nearly restrictive level does not allow for whatever existing programs to exist accessed, and does not let any new programs to be created. This mode makes the LED glimmer green. The 2d, more moderate Exam Way is the aforementioned, apart from iii additional applications being allowed (PlySmlt2, Inequalz and Conics). This mode makes the LED glimmer orange.
TI-84 Plus C Silvery Edition [edit]
The TI-84 Plus C Silver Edition was released in 2013 equally the first Z80-based Texas Instruments graphing calculator with a colour screen. Information technology had a 320x240-pixel full-colour screen, a modified version of the TI-84 Plus's two.55MP operating system, a removable 1200mAh rechargeable lithium-ion battery and keystroke compatibility with existing math and programming tools.[7] It had the standard ii.5mm I/O (DBUS) port and a mini-USB port for connectivity and charging. The figurer was praised for its loftier-resolution (relative to contemporary graphing calculators) colour screen, which allowed new pedagogical approaches such as graphing multiple functions together in dissimilar colors. It was widely criticized for its tiresome performance by educators and hobbyists/hackers akin[ commendation needed ]; the performance was attributed to the calculator retaining its monochrome predecessors' CPU to drive a screen displaying 300 times as much image information. Two years afterward, information technology was replaced past the TI-84 Plus CE, merely demonstrated the value of a color-screen TI-84 Plus-family computer, and was embraced by the calculator hobbyist community. Notable third-party milestones included overclocking the device from xv MHz to 22 MHz[8] and the last version currently published of the third-political party Doors CS beat out.[9]
TI-84 Plus CE and TI-84 Plus CE-T [edit]
The TI-84 Plus CE was publicly previewed past TI Education in January 2015,[10] and released Spring 2015. The calculator retains the 320x240-pixel color screen, rechargeable bombardment, and central layout of the TI-84 Plus C Argent Edition, while removing the 2.5mm I/O ("DBUS") linkport and moving the USB port and charging LED to the right side of the handheld. The calculator's Os 5.10 is incompatible with the TI-84 Plus C Argent Edition's hardware. In addition, the RSA signing key length has been increased to 2048 bits, making infeasible previous efforts to unlock the calculator to unrestricted third-party software development. The calculator has 154KB of user-accessible RAM and 3.0MB of Archive memory. It uses the eZ80 processor from Zilog, making all Z80 assembly programs from the previous TI 84 Plus series calculators incompatible. The CE was introduced in multiple colors (Classic (black), Silver Linings, Radical Ruby-red, Truthful Blue, Denim (navy blueish), Lightning (light blueish), Plum Pi (royal)); Positively Pink (every bit of March 2015), Golden Ratio, and Bright White (equally of June 2016) were added later, and further colors have since been released. Like the rest of the 84 Plus series, it is allowed on most standardized tests.[11] The calculator comes programmed with 7 different languages (English, French, German, Dutch, Portuguese, Spanish, and Swedish). In 2016, the TI-84 Plus CE-T was released for the European educational market. The only significant deviation from the CE model is the addition of an LED that blinks while the calculator is in Press-to-Test mode. CE calculators revision M and later (manufactured on and later on Apr 2019) incorporate an improved architecture with caching with a more contempo flash flake (Winbond 25Q32JVSIQ) than on previous revisions, which contained a Winbond W29GL032C. Due to this modify, more contempo revisions accept seen a significant improvement in overall speed. In 2020, TI Education announced its determination to remove support for assembly and C programming on these calculators in response to a video posted on YouTube detailing how to bypass the exam fashion on Os version v.ii.two. TI'south response was widely considered unnecessary, and led to anger from users. The changes are reflected in OS version 5.5.1 for the European models and Bone version 5.six for the US models. Currently, an exploit called Bamboozlement has been released that allows for native code execution through a bug in the CabriJR app.
TI-84 Plus CE-T Python Edition and TI-84 Plus CE Python [edit]
The TI-84 Plus CE-T Python Edition was released in 2021 and provides OS version 5.6 and above with the ability to program the calculator in Python and includes a preloaded packet of applications.[12] In the North American market, the TI-84 Plus CE Python has replaced the existing-TI 84 Plus CE in the fall of 2021.[13]
Software [edit]
There are 3 unlike types of programs which tin can be downloaded or programmed into the calculators: TI-Bones, Z80 associates linguistic communication, and Flash applications (too written in Z80 associates). The TI84+CE is different in that programs are written in TI-Bones, eZ80 associates language, or in the C programming language. In addition, at that place are programs bachelor that are able to compile or translate other programming languages. The TI 84 Plus CE-T Python Edition supports the Python programming language. Too, there are several languages developed by customs members for the calculators, notably Ice, which is for the TI84+CE, and Axe, which is for the TI84+ and TI84+SE. At that place are a wide range of applications that this produces, from science classes, to games, to calculus to note taking (when put together with a separately sold keyboard). The TI-84 Plus Serial is exactly similar its predecessor in that it can exist used on the Sabbatum and ACT examinations as well as International Baccalaureate examinations. However, in some cases those administering the exam may reset the calculator'south retention beforehand to prevent adulterous through the employ of congenital in programs or other data.[14]
When OS 2.30 was initially released, users noticed the speed of graphing was greatly reduced. The explanation was that the update added asymptote checking in graphing.[fifteen]
In January 2006, Texas Instruments released v2.40 of the operating system for the TI-84 Plus serial. The well-nigh noticeable addition to the new OS was the "Press-To-Examination" characteristic that allowed a teacher to disable any programs installed on the figurer, so they cannot be used on tests, etc.[xvi] As of Bone version 2.53MP which was released in February 2010, support was added for prettyprinted expressions. Withal, some programs stopped working correctly in this Bone version, or were running slower.[17] The electric current Bone version is 2.55MP which was released in Jan 2011.[18]
In July 2009, a community-made patch was released which immune user-made operating systems to exist easily uploaded onto the TI-84 plus series. Shortly after the patch was developed, the RSA keys for the estimator's operating system were factored via the General number field sieve (GNFS) algorithm, making a software patch unnecessary. In response to this, Texas Instruments released a newer hardware revision which only accepts other, stronger RSA keys, making information technology harder to load user-made operating systems or older TI operating systems (2.53MP and before). The community has found a way around the newest limitation by discovering a style to revert to older versions of the boot lawmaking.[19]
The TI-84 Plus CE-T Python Edition supports using CircuitPython, a python 3 variant, developed past Adafruit. Merely the math and random modules are initially supported but it is possible that wider back up will go available either from TI or from the community.
Critics point out that the basic design of the TI-84 has not inverse since it was released in 2004, contrary to the trend of rapid design change occurring in other areas of electronics manufacturing.[20] [21]

Programming [edit]
The TI-84 Plus is based heavily on its predecessor, the TI-83 Plus. As with all other calculators in the series, the TI-84 Plus supports native Z80 assembly as well as TI's interpreted, BASIC-like language for calculators, dubbed TI-Bones. Programming for the TI-84 Plus is nearly identical to programming for the TI-83 Plus, with a few new functions in both TI-Basic and the estimator's assembly support that practice not exist on earlier models and OS versions. Several attempts have been made at creating a C to Zilog Z80 assembly assemblers, such as SDCC.[23]
The TI84+CE series can exist programmed in TI-Basic, eZ80 assembly, or with the C programming language.
The TI-84 Plus calculators' dialect of TI-BASIC is the same as that of the TI-83 Plus series, but with a few more commands including ones for date and time.
Texas instruments removed support for Assembly and C in Firmware 5.5.[24] Almost immediately, nonetheless, a jailbreak called artifice was written that restored compatibility.[25]
