The .8pu file format is associated with the TI-83, a programmable graphing calculator developed by Texas Instruments. The calculator uses a Zilog Z80 processor.
A .8pu file stores data used by the TI-83. It is a calculator-specific data file rather than a general-purpose document intended for direct use in ordinary desktop applications.
TI Connect for Microsoft Windows and the multiplatform TiLP software can manage compatible TI-83 data files and transfer them between a computer and calculator.
Open a .8pu file with TI Connect on Microsoft Windows or with TiLP on a supported platform. These programs are intended to transfer and manage TI-83 data rather than display it as a normal desktop document.
Connect the TI-83 calculator when necessary, then use the software's file-transfer or device-management functions to access the file.
There is no general-purpose conversion for a .8pu file. It contains data for the TI-83 and is normally transferred to or from the calculator with TI Connect or TiLP.
If the calculator or transfer software provides an export function for the particular data, use that function to create a more accessible representation.
