Best distro for very old hardware ;) Runing very smoothly on 256MB is a miracle :)
Mint, LXLE and others does not work on old Thinkpads. Mine is a Thinkpad R50. Tried them "all". "Xubuntu 12.04 is the last of the family shipping with a non-PAE kernel. True, you can hack your way around, but from the official stand point, the vendor does not intend to support ancient processors beyond 2017." (ww.dedoimedo.com/computers/reviving-ten-year-old-laptop-linux.html) Most older distros are removed from downloads, no Xubuntu 12.04 anymore, also no torrent. Anyhow I succeded finding an Ubuntu 8.10 and it WORKS! Took hours to get there, upgrades are now pending.
