TI-85—Originally designed with the engineering student in mind, this obsolete calculator was actually missing some of the useful features (such as tables) included when the TI-82 was introduced. Stay away from this one also. TI-86—This is the upgrade of the old TI-85 and requires a completely different set of commands.
But the TI models remain perfectly suited for the high school classroom, year after year. Until educators are ready to radically change their teaching methods, textbooks, academic handouts, and exam protocols the TI graphing calculator will remain the one that the majority of teachers recommend or require.

The TI-86 is a programmable graphing calculator introduced in 1996 which was produced by Texas Instruments. The TI-86 uses the Zilog Z80 microprocessor. It is partially backwards-compatible with its predecessor, the TI-85.
The TI-83 Plus was designed in 1999 as an upgrade to the TI-83. The TI-83 Plus is one of TI's most popular calculators. It uses a Zilog Z80 microprocessor running at 6 MHz, a 96×64 monochrome LCD screen, and 4 AAA batteries as well as backup CR1616 or CR1620 battery.
The TI-92 was originally released in 1995, and was the first symbolic calculator made by Texas Instruments. It came with a computer algebra system (CAS) based on Derive, geometry based on Cabri II, and was one of the first calculators to offer 3D graphing.

Several Texas Instruments graphing calculators will be forbidden, including the TI-89, TI-89 Titanium, TI-92, TI-92 Plus, Voyage™ 200, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, and TI-84 Plus Silver Edition, TI-Nspire™ and TI-Nspire™ CAS.
Compared to the TI-84, it has a bigger screen (128×64 pixels), uses long variable names (up to 6 symbols), and has superior handling of matrices, lists, and vectors. Compared to the TI-89 and the Voyage 200, the TI-86 has a much more intuitive interface, especially when programming your own functions and programs.
How do I connect my TI-85 to my computer?
Connect the TI Connectivity Cable to the serial or USB port of your computer and to the port at the bottom edge of the TI-82, TI-73, TI-73 Explorer, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-85, TI-86, TI-89, or the top edge of the TI-92, TI-92 Plus, or Voyage 200 graphing calculator.
One interesting advantage of the TI-83 (the initial model) over the newer, more powerful, and more sophisticated TI-89 is that, as many users have noted, the former tends to plot regular plots faster than the latter. Presumably, though, the plots produced by the TI-89 are likely to be more accurate.
The TI-84 CE Plus is the latest in a long line of TI-84 calculators, but with a better color screen, battery life, software, and a more compact size. It is the most widely adopted, widely trusted calculator by teachers in American classrooms.
One major concern is cheating. People can enter information into their calculators that may give them an unfair advantage on the exam, in essence using the calculator as a "cheat sheet". Having a professor verify that a couple hundred students don't have any information stored in their calculators isn't feasible.
Yes, in many instances teachers allow students to use TI graphing calculators on class tests. In fact, graphing calculators are permitted, or even required, on many college entrance exams and state exams.

When properly maintained and under normal usage, batteries are expected to last about 3 years. If you use the handheld/graphing calculator regularly, recharge the battery often. Avoid waiting until it is fully discharged.
Not to be outdone, Texas Instruments introduced its first calculator, the Datamath (or TI-2500), later that year. The device carried out basic arithmetic and sold for $149.95. In 1973, TI introduced the SR-10, its answer to the HP-35.
This is an example of the first graphing calculator sold by Texas Instruments. The TI-81 was introduced in 1990.

1. German 19th-Century Brass Calculator. The German 19th-Century Brass Calculator holds the record for being the most expensive calculator ever sold, with an astonishing price of $11.8 million! At first glance, you might wonder why it costs so much, but its rarity and unique features explain its worth.
The TI-89 introduced in March 1998 could be called the most enhanced calculator of the pre-2000 time. It combines the capabilities of the TI-92 Symbolic calculator with state-of-the-art Flash technology in a normal sized hand-held calculator case.
The TI-83 plus came out before the TI-84 and so the TI-84 is the superior calculator, but not by much.

When did TI-30 release?
The TI-30 is a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976. While the original TI-30 was discontinued in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators.
Texas Instruments introduced the original TI-73 already in 1998 as the first graphing calculator dedicated for the middle grades.
The TI-68 was a scientific pocket/desktop calculator produced by Texas Instruments. It was introduced in 1989 and was modified in 1991 to produce a less expensive and possibly more durable version.
Then, Texas instruments made a very unpopular decision: it decided to discontinue it. Apparently the company was afraid that it would jeopardize the sales of their newer models, the TI-83 and the TI-92 Plus.

Technology has not yet killed the reliable old TI-83. Nearly 20 years later, students are still forced to use a prohibitively expensive piece of outdated technology. It's not because better tools aren't available; they exist, and some of them are even free.
The TI-86, being a discontinued calculator, has a number of different recommended replacements. For engineering and AP courses, the TI-89 Titanium and TI-Nspire CX II CAS are the recommended substitutes. For general math and science courses, we recommend the TI-84 Plus Family or the TI-Nspire CX II.
The TI-85 is a graphing calculator made by Texas Instruments based on the Zilog Z80 microprocessor. Designed in 1992 as TI's second graphing calculator (the first was the TI-81), it was replaced by the TI-86, which has also been discontinued.

the ti83+ is the best _BEST_ calculator for statistics. you will find it invaluable for that course. the ti86 isnt as good as the 83+.
The TI-86 actually contains 128K of memory, even though only 96K of it is normally allowed for variables. You can add some of this memory to the variable space by running the 'Pterodactyl Memory Expander' program written by Kirk Meyer. This allows you to use up to about 111K of memory to store variables.
A TI-83 will set a student back around $100, while the TI-84 still costs more than $100. Most obsolete gadgets lower in price (consider this $10 flip-phone), but the humble graphing calculator continues to boast a hefty price tag. What gives? It's all about supply and demand.
