Eagle 4.14

I don't get this thread at all. There's an assumption that symbols or footprints require library files which is incorrect. So, the assumption that an old particular version of EAGLE is required based on that, is also not the case.

The OP mentions that version 5 of EAGLE was missing symbols. Maybe they were actually not in the original project(s). They were created by students after all. Some screenshot would help but OP doesn't seem to want to share any example to demonstrate the problem.

It makes no sense to seek such a particular ancient version of EAGLE. Simply use a more recent version, then save the file in the most recent format. Then import into the CAD package of your choice (e.g. KiCad if you wish - your choice).

Agreed - that was my suggestion 4 days ago.  I don’t have time to open the zip but do / did older Eagle files contain XML?  In that case, the missing component may be named in the human-readable file even if missing as a symbol or footprint.

Hi shabaz,

Thank you very much for your attention to my matter.
I didn't mention that the projects were carried out by students, I mentioned that they were part of a robotics group that included our entire school community.
The message dougw put "Eagle design files do include all component information." led us to try to find, in our network of contacts, at least one of the group members to clarify some points, but so far it has not been possible to contact anyone.
Since you show a lot of interest in helping us, I will publishy a file that has already been opened in Eagle version 5.11.0.
I think this file that I'm going to send will not have any legal issues.
In this case, from the file name we can identify that the missing component must be a Timer, but which one?
By the way, I should mention that our first obstacle was not the Software but rather the 3.5'' floppy disk readers to get the files.

Best reagrds.
