ZIP archive named Tebo-View, which appears to contain the TeboView boardview viewer or related files rather than data for a specific board. No device, board number or version is given in the name. Programs of this kind open common boardview formats and display part locations, pin nets and test points, which is useful for checking continuity and tracing a short. Scan extracted executables before running them, and keep a second viewer such as OpenBoardView available for formats it cannot open.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @ITHINKHS. Enginerys does not host this file.
