summary

AOSC OS/Retro describes running a modern, systemd- and glibc-based Linux distribution on vintage hardware by sharing AOSC OS’s source tree and trimming/configuring the same toolchain and userland (GCC, Binutils, Coreutils, util-linux, X.org/Mesa). It covers porting and optimization efforts across eight architectures (alpha, armv4, armv6hf, armv7hf, i486, loongson2f, powerpc, ppc64), compiler-flag tuning and desktop design to make the distro usable on machines from 486SX to Core Duo, and remaining issues like login delays and ISA I/O throttling.
