Opening TEC files

Did your computer fail to open a TEC file? We explain what TEC files are and recommend software that we know can open or convert your TEC files.

What is a TEC file?

Files that contain the .tec file extension are commonly used for PDP-10 TECO macro files. These files were created for the PDP-10 mainframe computers that were manufactured by DEC.

PDP-10 stands for Programmed Data Processor Model 10. A variety of universities used these machines in their research labs and computing facilities. These computers were most popular during 1963 through 1966.

The Tanner Ledit software application also uses the .tec file format. These TEC files contain layout technology data files that are used by the Tanner Ledit program.

The TECkit software also uses the .tec file suffix. TECkit is an acronym for Text Encoding Conversion toolkit. The TEC files that are used by this software contain a compiled version of the text mappings that are saved in the software's MAP files.
