"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 usb link cable (sold separately)." - Wikipedia

• Key features of the TI-86 math and science:

  Memory 128K RAM with 96K user-available. Powerful calculus features Integration, derivatives, minimums, maximums, roots, and arcs. Function evaluation table Evaluate graphs in the TI-83 style table format. TI-83 style list and matrix editor improvements Allows data exploration for lists up to 6,000 elements long and up to 80 x 80 matrices. Assembly Language Programming In addition to the regular programming capabilities, the TI-86 also supports Z80 assembly language programming. Input/Output port Allows linking with TI-86s, TI-85s, CBL 2s™, CBLs™, CBRs™, and computers. New, easy-to-read, high contrast display Shows 8 lines of 21 characters each or 64 x 128 pixel screen plus two levels of display menus. Tables Function evaluation table shows numeric output for function, polar, parametric, and differential equation modes. Keyboard entries Improved interactive graphing. Choose from a line graph, thick line graph, improved shading, and more. Enter specific values at prompts for math operations and during tracing. List editor View multiple lists at one time in an improved stat/list editor. Attach formulas to lists for automatic computation. Differential equations Solve nine first-order differential equations or up to one ninth-order differential equation. Easily solve a family of curves with a list of initial values. Interactively select initial conditions via the graph screen. Slope & direction fields Additional tools for exploring differential equations. Pause first or immediately follow the slope or direction field with a graph of the solution or a family of solutions. In addition, choose from two methods (RK and Euler) to solve your differential equations. Equation solving tools Interactively solve for any variable in an equation with the built-in SOLVER. Build a library of equations to solve and share via the link port. Simultaneous equation solver. Polynomial root finder solves real and complex polynomials up to 30th order. Matrix editor The TI-86 contains enhanced tools for solving a variety of linear algebra problems. Matrix abilities include: eigenvalues, eigenvectors, determinates, ref, rref and more.
