Just pulled out the T43p and upgraded it to 7.3. It’s so slow, with the PATA plater drive and single core; but it still chugs along and so I pull it out every once and again to update and browse the web like it’s 2005.

And of course OpenBSD still runs just fine. It’s probably been half a decade since the XP install was wiped and replaced with whatever the then current OpenBSD release was. I used to pull the bsd.rd from http and boot that from the loader prompt; these days, sysupgrade(8) and syspatch(8) do all the work.
