And I have no acces to startrom.0
Neither to cabextract and not to startrom.n12

So where the Original Poster did bring a problem to the mailinglist,
is this E-mail about returning that problem. [1]

IMO should the OP make two tarballs (or zip files)
Each with all the TFTP files for a RIS install.
One is "version 3.75" and the other "version 3.80"

And put them on the Internet.
