A suite of TI-86 features is being created for the TI-83 Plus and TI-89 in the form of free APPS, including the Polynomial Root Finder, Simultaneous Equations Solver Differential Equation Graphing (built into the TI-89), and Constants and Conversions (built into the TI-89).

Key features for 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.

New 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.

New 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.
