TI-89 Graphing Calculator - Where can I find the data cable locally?

Hi!

I have the older-style TI 89 (not the titanium) graphing calculator. Does anybody know where I might be able to pick up the USB cable? I tried calling Best Buy, Radio Shack, Staples and Meijer. Thanks!
 
Thanks for your reply. I was looking to purchase this locally.

I don't think you can...

If it's an older TI and, you will likely find only the newer cables at Staples/Office Depot/Best Buy.

example, I have a really old TI-89 with the earphone to USB cable. You can't find this cable anywhere!

I'm sure I could probably get the cable from ebay for $5.00
 
Ha - that's the cable that I'm looking for!

I have 3 of those calc at home.

2 TI-89
1 TI-83.

My daughter will need a TI-something soon. Personally I would rather go out and buy her the newest out there, then messing around with a older calc. I'm sure there's not much difference but it's newer hardware and more memory. Yeah the newer ones I think use all USB or Micro USB...

You can even build the cable yourself. There's millions of docs online on building the cable.
 
I remember a few of the kids had the TI-89 Voyager. The thing looked like a game gear etc.. It was almost twice as much as the TI-89 and it was the bomb...

wasnt that for the parallel port adapter? it's just a few parts i remember - a few diodes and a resistor or something... but then you have to track down a 2.5mm? TRS plug or jack

Absolutely,

The hardware of the older TI-89 allowed it to directly connect to Serial. It was a simple interface. You could build the cable with two diodes, two resisters and a LED (for indication).

Now, what computer still has a serial!!! So you would have to build a USB version, which is more complex

That's an oddball part, so I doubt you'd get one locally.

Of course there's the unethical and totally non-endorsed way to get one locally, but don't do that.

But you don't give your location.
 
Had the TI-89 Titanium through college. Thing was (and still is) a beast. That is if you take the time to learn how to use it of course....

Honestly most people just used the calculators as a cheating tool. Everyone knew this. You could put a whole bunch of shit in the calc (cheat sheet).

In NY, there was a Casio version that was making some headway. Suddenly, the rules changed, and if the calculator could simplify sqrt(48) into 4sqrt(3), then the calculator wasn't allowed. If you look at all the features graphing calculators have, that's a pretty trivial thing. But, gosh darn it, now you have to buy a TI. New rule: EVERY student in high school in NY taking Algebra (required), Geometry, or Algebra II/Trig *must* have a graphing calculator.
