About 73P files

The .73p file format is a proprietary calculator program originally developed for the Texas Instruments TI-73 series graphing calculators. These files contain instructions written in TI-BASIC or Z80 Assembly, allowing students and educators to run custom educational apps, math tools, and basic games directly on the physical calculator hardware. To interact with these files on a modern computer, users must rely on official software like TI Connect or third-party emulators like Wabbitemu. The primary disadvantage of the .73p format is its extreme hardware specificity and proprietary nature. It requires a specific physical device or specialized emulation software to open, and because the internal code is tokenized into a binary format, you cannot simply open it in a standard text editor. Users often need to convert these files because the original hardware is largely obsolete, making it nearly impossible to retrieve or read the legacy scripts without proper tools. The best conversion target is TXT, which allows users to read the raw TI-BASIC source code. Some users also attempt to convert to 83p or 8xp to migrate programs to newer Texas Instruments calculators, though syntax differences often lead to data loss or require manual code adjustments. This file format is notoriously difficult to open or convert because the tokenized data structure is closed and officially undocumented. Generic file converters will fail because only the original software can properly map the hexadecimal tokens back into readable text.

Convert.Guru analyzes your 73P file, detects the exact format, and lets you read the text inside.

Users also converted 73I, 73K and 73L files.

The 73P Converter Story

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 73P converter.
