The 85d file extension is associated with the TI-85, a programmable graphing calculator developed by Texas Instruments. The calculator uses a Zilog Z80 processor.
An 85d file contains a graphic database from a TI-85.
TI Connect for Microsoft Windows and the multiplatform TiLP software can be used to work with TI-85 data files.
An 85d file is not normally opened as a standalone image on a computer. On Microsoft Windows, use TI Connect to transfer or manage the file with a compatible TI-85 calculator.
TiLP can also be used on supported platforms for communication with the calculator and for handling its data files. A compatible calculator connection may be required.
To use an 85d file, transfer it to or from a compatible TI-85 using TI Connect or TiLP.
