Introduction
There is a wide variety of modifications you can make to your calculator. The only "supported" accessory of any use to us is the Graph-Link, but some clever hackers with too much free time have modified their calculators to improve speed, add memory, and even install things like EL backlighting ("Indiglo") and IR link ports.

All of these upgrades (except the TI Graph-Link) are unsupported by TI. For info on how to buy or build one of these accesories, click on the appropriate link.

 

TI-73

Released in 1998, the TI-73 is designed for middle school students taking basic algebra. This is the new version of the discontinued TI-80, and features flash upgradability, additional statistics functions and a link port.

Memory 25K RAM, 64K Flash ROM
Screen size 96x64 pixels, 16x8 characters
Link port Yes
Programming platforms BASIC, Flash (apps)

Released in 1995, the TI-80 was designed for middle school algebra I and precalc students. It has been discontinued and replaced by the TI-73.

Specs:

Processor 900 kHz Proprietary
Memory 7K RAM

TI-81

Released in 1990, the TI-81 was TI's first graphing calculator. It has no link port, so there aren't many programs for it, since they have to be typed in by hand. Ths TI-81 has been discontinued and replaced by the TI-82, TI-83, and TI-83+.

Specs:

Processor 2MHz Z80
Memory 2.4K RAM
Screen size 96x64 pixels, 16x8 characters
Link port No
Programming platforms BASIC

TI-82

Released in 1993, the TI-82 was made to be a more affordable and user friendly version of the TI-85, at the sacrifice of some advanced features. It is the predecessor of the TI-83 and 83+. There are two versions, the old version, and the current version. It will probably be discontinued soon. It can be programmed in assembly, but it must be hacked. Assembly programs require a shell like OShell-82, Ash, or CrAsh.

Specs:

Processor 6MHz Z80


Old TI-82 | New TI-82

Memory 28K RAM
Screen size 96x64 pixels, 16x8 characters
Link port Yes
Programming platforms BASIC, OS-82, Ash, CrAsh

TI-83

Released in 1996, the TI-83 is the most popular of the TI graphing calculators. It is mainly for students in middle school to high school. It was the first to feature the new curved body that is standard on all current calculators, and was also the first to feature built-in support for assembly programs. It is the successor of the TI-82 and the predecessor of the TI-83+ and TI-83+ Silver Edition. It is fully backwards compatible with the TI-82.

Specs:

Processor 6MHz Z80
Memory 27K RAM
Screen size 96x64 pixels, 16x8 characters
Link port Yes
Programming platforms BASIC, Assembly, Ion, others

TI-83+

Released in 1999, the TI-83+ is practically identical to the 83, with the addition of flash memory. It is almost completely backwards compatible with the 83. The only incompatibility is that 83+'s can't run 83 assembly programs, and 83's can't run 83+ assembly programs. However, there is a shell called Ion that is compatible with the 83 and 83+.

Specs:

Processor 8MHz Z80 at 6MHz
Memory 24K RAM, 160K Flash ROM
Screen size 96x64 pixels, 16x8 characters
Link port Yes
Programming platforms BASIC, Assembly, Ion, Flash

TI-83+ Silver Edition

To be released in the spring of 2001. The TI83+ SE is a completely revamped version of the TI-83+. In addition to the translucent silver body, the TI-83+ SE has a 15MHz Z80 processor, and 1.5 megabytes of Flash ROM, enough to store 94 apps. Backwards compatible with the TI-83 and TI-83+.

Specs:

Processor 15MHz Z80
Memory 24K RAM, 1.5MB Flash ROM
Screen size 96x64 pixels, 16x8 characters
Link port Yes
Programming platforms BASIC, Assembly, Ion, Flash

TI-85

The TI-85 was released in 1992. It was a poweful calculator that has many uses in engineering and calculus. It was the first calculator to have a link port, and was also the first to be programmed in assembly. Since there is no built-in assembly support, assembly programs must be run through an unintentional loophole with a shell like ZShell or Usgard. It has been discontinued and superseded by the TI-86.

Specs:

Processor 6MHz Z80
Memory 28K RAM
Screen size 128x64 pixels, 21x8 characters
Link port Yes
Programming platforms BASIC, Usgard, ZShell, Rigel, PhatOS

TI-86

The TI-86 was released in 1997 as a successor to the TI-85. It also sports a contoured body and built-in assembly support, as well as more memory and advanced features.

Specs:

Processor 6MHz Z80
Memory 96K RAM
Screen size 128x64 pixels, 21x8 characters
Link port Yes
Programming platforms BASIC, Assembly

TI-89

The TI-89 was released in 1998 and is one of the most powerful calculators of all. It sports a Motorola 68000 processor, a high-resolution screen, lots of flash memory, and tons of advanced features like 3D graphing and equation solving.

Specs:

Processor 10-12MHz MC68000
Memory 188K RAM, 384K Flash ROM
Screen size 160x100 pixels

TI-92

Released in 1995. When it was released,TI-92 was unlike all other TI calculators. It was held horizontally, had a QWERTY keyboard, a Motorola MC68000 processor, and tons of advanced features. It has been eclipsed by the TI-92 Plus and the handheld TI-89. Note that the TI-92 cannot be used on some standardized tests because of its QWERTY keyboard. Assembly programs must be run through an unintentional loophole using shells like Fargo and Fargo II.

Specs:

Processor 10MHz MC68000
Memory 68K RAM
Screen size 240x128 pixels
Link port Yes
Programming platforms BASIC, Fargo, Fargo II

TI-92+

Released in 1998 with the TI-89. The TI-92+ has all the same features of the TI-92, with the addition of flash memory and assembly support. It is fully compatible with the TI-89. Note that the TI-92+ cannot be used on some standardized tests because its QWERTY keyboard qualifies it as a computer.

Specs:

Processor 10MHz MC68000
Memory 188K RAM, 384K Flash ROM
Screen size 240x128 pixels
Link port Yes
