I'm gathering some old ISOs of Ubuntu MATE to preserve a bit of history, plus I might use them for taking screenshots for a future website update. However, I can't seem to find copies of the i386 or amd64 builds of the very first 14.10 release!
(14.04 actually was the second release while Ubuntu MATE was an unofficial "remix")
Luckily, I managed to salvage 45.3% from an archived amd64 link on the Internet Archive, but it's missing the remaining 54.7%.
If you've still got a copy, please consider adding it to your Bittorrent client and seed it to spread the retro-re-retrospective past.
