Extract text from TI-86 programs (86P)
To convert 86P programs to another format, you need TI Connect or other Developer software.
To convert other file formats to the "Calculator Program" file type, you need software like TI Connect or a similar tool.
The .86p file extension represents a program file specifically designed for the TI-86, a Z80-based graphing calculator by Texas Instruments. These files contain executable scripts, typically written in TI-BASIC or Z80 assembly, ranging from complex calculus solvers to games like Tetris.
The Problem (Tokenized Binary): A major issue for users is that .86p files are not plain text. The calculator stores commands as proprietary binary tokens to optimize limited memory. Consequently, attempting to open a .86p file in a standard code editor like Visual Studio Code displays unreadable symbols and garbage data. Additionally, because the TI-86 was discontinued in 2004, relying on the legacy TI Connect software is risky due to poor driver support on modern Windows and macOS systems.
The Solution (Conversion): To view, edit, or print the source code, you must convert the .86p file to a TXT or PDF. This process "detokenizes" the binary data back into human-readable commands. If you intend to run this program on a modern calculator (like the TI-84 Plus CE), you cannot simply transfer the file; you must first convert the logic to text and then adapt it for the 8xp format, as the syntax differs significantly. For quick access without installing emulators, simply upload the file to view and convert it.
Convert.Guru analyzes your 86P file, detects the exact format, and lets you read the text inside.
Users also converted 89P, 82P and 89Y files.
If you want to convert 86P file to [% faq_exts_to %], you can use TI Connect or similar software from the "Calculator Program Storage" category. In the File menu, look for Save As… or Export….
To convert [% faq_exts_from %] files to 86P, try TI Connect or another comparable tool in the "Calculator Program Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our 86P converter.
