Texas Instruments TI86 Graphing Calculator Review

The TI-86 is a programmable graphing calculator introduced in 1997 and 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-86 can be thought of as the tier among various Texas Instruments calculators directly above the TI-83 and TI-84 line. In addition to having a larger screen than the TI-83, the TI-86 also allows the user to type in lower case and Greek letters and features five softkeys, which improve menu navigation and can be programmed by the user for quick access to common operations such as decimal-to-fraction conversion. The calculator also handles vectors, matrices and complex numbers better than the TI-83. One drawback, however, is that the statistics package on the TI-83 range doesn’t come preloaded on the TI-86. However, it can be downloaded from the Texas Instruments program archive and installed on the calculator using the link cable.

Let’s take a look at all of the Texas Instruments TI86 features/specification:

  • Graphing functions
  • Powerful calculus features
  • Function evaluation table
  • 128K RAM with 96K user-available
  • Input/output port

If you want to buy Texas Instruments TI86, you can get it cheap online through Amazon.com here. They offer special discount price and reliable shipping service.

Let me show you what current owners have to say about it:

“…I bought this around mid 1997 and I’m still using it to this day.
It’s helped me through AP Calc, Calc II, Calc III, Differential Equations, Advanced Engineering Math, SATs, GREs, Fundamentals of Engineering exam for EIT certification, and etc…

I actually bought a TI-89 around soph year of college just to complement the TI-86.

You see, the TI-86 is a SOLID engineering calculator. It’s got fast units conversions, an intuitive and FAST menu system BUT it lacks “pretty print”, handling of units for math (keeps the units throughout equations, calculators), and integration/differentiation with the variables in place (it doesn’t just evaluate it). With the right software, the TI-89 is a very powerful math tool.

I used the TI-89 primarily for theoretical math but came in handy for standardized tests as well.

I would recommend getting both the TI-89 and TI-86 and start familiarizing yourself with both calculators before you start tackling tests. Check the rules and regs for calculators also – standardized tests should allow the use of the 86 and 89.

Overall, the TI-86 is a solid math tool – notice I say TOOL because that’s what it is. If you have no idea what you’re doing in class, the TI-86 won’t give you an A.

My recommendation is to get both the TI-86 and TI-89.
Just FYI, I’m still using the TI-86 at work. The buttons show some wear and I lost the first line of the LCD because I dropped it in college. Nonetheless it’s still chugging along.

Also, slap in four 750mAH NiMH batteries. You will NOT regret this because these calculators drain alkaline batteries in half a semester of intensive use. We didn’t have cheap NiMH batteries back in the day – TI actually pushed the use of Rayovac Renewals (remember those rechargeable alkalines that only lasted 5 charges?) and our other choice was NiCd. Forget all that. Slap in four Energizer 750mAh NiMH batteries and you’ll save yourself a LOT of money in the long run. That means more money for video games and other forms of entertainment in college…”

If you want more info on this Texas Instruments TI86, I suggest you take a look at the Texas Instruments TI86 reviews on Amazon here. A lot of consumer positive response to this Texas Instruments TI86 here.

Here is why Texas Instruments TI86 is worth buying:

Texas Instruments TI86 Graphing Calculator : Pro

  • Speedy interface, lot’s of function, good resolution screen, lots of good games, GREAT value
  • Does everything you need for Pre-Calc, lightweight, good display screen
  • deriving function, very durable, has a pretty curve on the front

Texas Instruments TI86 Graphing Calculator : Con

  • Graphing speed a bit slow, no flash rom

Conclusion

The Ti-86 is the best calculator without CAS and I recommend it %100.
