The 85p file extension is associated with the TI-85, a programmable graphing calculator developed by Texas Instruments and based on a Zilog Z80 processor.
An 85p file stores a program written for the TI-85. It is calculator program data rather than a conventional document intended for reading on a computer.
The format is specific to the legacy TI-85 calculator. TI Connect is available for Microsoft Windows, while TiLP supports multiple operating systems and can transfer compatible files between a computer and calculator.
On Microsoft Windows, use TI Connect to manage or transfer the 85p file to a TI-85. On other supported platforms, use TiLP.
These programs are primarily intended to transfer the program to the calculator; the file may not display as readable source text when opened directly on a computer.
An 85p file generally does not have a useful standalone conversion to a common computer file format. To use it, transfer it to a compatible TI-85 with TI Connect or TiLP.
