Archive of files from TI's FTP server for the TI-86 graphing calculator.
No, I don't have anything for the other calculators, sadly. Considering that the 83/84 is still supported, those shouldn't be too hard to find. As per my instructions on archive.org for this:
You will need the following in order for transferring files onto a real TI-86 on a modern system:
- The Silver GRAPH-LINK cable for USB. TI doesn't appear to make these anymore but they do seem to be easy to find still.
- TI Connect 4.0 on Windows. TI Connect CE won't work since those are for the 83 and 84 family. TI Connect 4.0 may work on Mac still but I haven't tried it on macOS Mojave yet.
- A TI-86 (obviously)!. The included files won't work on the 83 and 84 family of graphing calculators.
