The perfect calculator. It is more than a calculator: it is a powerhouse! Too bad TI discontinued it. I am collecting as many as I can. The one and only TI-86. Great for engineering. It has graphing, programming, all kinds of functions. Variables and all other objects can have any names with many characters. Built-in interpolation. Vectors. Also, this new Amazon renewed program is GREAT! I didn't know about it. Thank you Amazon; I now can have a real engineering calculator (Vintage Calculator).

Está como nueva, se ve y funciona increíble. Lo único que le faltó fue el cable, pero un detalle desde mi punto de vista.

Graphs inaccurate. Calculations of trigonometric values are inaccurate. Doesn't change from radians to degrees.

I love this platform. As a guy who went to college with one and it’s operation has become second nature to me it’s hard to move on. I think Texas Instrument should have their heads examined for discontinuing this but that’s another issue. Didn’t come with a cable and the factory batteries didn’t work but the calculator is great and works great so I’m super happy with my purchase. Love it!
