Yes, but only what was mirrored to usenet: https://usenetarchives.com/groups.php?c=fido

But usenetarchives has had some enshittification happen.

This one still has some of the more fun files: http://textfiles.com/bbs/FIDONET/

There is also a Giganews dump on archive.org: https://archive.org/details/giganews And this one: https://archive.org/details/usenet-fido

Google stopped being useful for usenet a while ago but still has some if you can find it.
