Still use one cheap HP Compaq XP business machine from 2006, Pentium D which is really just two 32-bit Pentiums on one die to equal an early 64-bit AMD64. Runs W11 just fine once you coax it into existence on a BIOS PC. Linux too.
A slightly older XP Dell only has a single-core 32-bit CPU so no W11 for you, but W10 32-bit is still current and there's only 4GB of memory anyway. Debian on 32-bit looks like it may be supported for somewhat longer. Uses parallel PATA and/or serial SATA drives.
Both have floppies, parallel printer ports, serial COM ports, dual DVD readers/burners and telephone modems.
