I looking for Trisquel 9.0.2 with sources i686 etc, because I need i686 platrorm.

First of all, have you checked (for instance executing lscpu in a terminal) your CPU architecture is not x86_64? x86_32 is rare nowadays. If your architecture is really 32-bit, then see https://trisquel.info/forum/32-bit-os and, in particular, andyprough's first reply, which lists 100% free GNU/Linux distributions that, unlike Trisquel, still support 32-bit architecture. As he wrote, "the most similar to Trisquel seems to be Gnuinos". If you are willing to learn more about system administration, you can go for Parabola, which is based on Arch.

linuxtracker.org claims to have a Trisquel 9.0 i686 ISO torrent available. I haven't tried to download it myself, and not sure if it's just 9.0 or 9.0.2 or what. But anyway, if that's what you need, you might want to check it out.

It may be worth noting that Trisquel 9 has reached end of life on May 31 this year, and is thus not supported any more. It is my personal GNU/Linux ISO torrent policy to remove anything that has reached EOL, but that Trisquel 9.0_i686 torrent indeed seems to be still seeding as of today.

To complete Magic Banana's reference to andyprough's assessment, the Gnuinos ISO images can be downloaded there: https://www.gnuinos.org/mirror/chimaera/live. This is a different project to Trisquel, though, so user experience is going to be noticeably different. Not so much from Trisquel Mini, though. Anyway, certainly worth giving a try for 32-bit platform users.
