TI-86
The TI-86 is a programmable graphing calculator introduced in 1996 which was produced by Texas Instruments, it is powered by a Zilog Z80 microprocessor, as used in the TI-73 and TI-81 to TI-86. It is partially backwards-compatible with its predecessor, the TI-85. 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.

Overview
Overview
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. The TI-86 has been discontinued.
