A kickstand-style slide case and other accessories are also available. Owners can buy other interchangeable colored face-plates and slide-cases online. This special design was produced in an effort to combat theft. TI offers a special yellow version of the TI-84 Plus, inscribed with the words "School Property", for schools to loan out to students. These programs are also available for the TI-84 Plus, but some must be downloaded separately from TI's website. The TI-84 Plus Silver Edition comes preloaded with a variety of applications. It uses 4 AAA batteries and a backup button cell battery. Like the standard TI-84 Plus, the Silver Edition includes a built-in USB port, a built-in clock, and assembly support. There is 1.5 MB of user-accessible Flash ROM.
All calculators with the letter H or later as the last letter in the serial code have fewer RAM pages, causing some programs to not run correctly. Newer calculators have a RAM chip that is only 48 kB. The chip has 128 kB, but Texas Instruments has not made an OS that uses all of it. Like the TI-83 Plus Silver Edition, it features a 15 MHz Zilog Z80 processor and 24 kB user available RAM.
The TI-84 Plus Silver Edition was released in 2004 as an upgrade to the TI-83 Plus.
The archive ( ROM) is about 3 times as large, and CPU about 2.5 times as fast (over the TI-83 and TI-83 Plus). The key-by-key correspondence is relatively the same, but the 84 features some improved hardware.
The TI-84 Plus is an enhanced version of the TI-83 Plus. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE.
