WSL9x brings Linux to Windows 95
Hailey Somerville released WSL9x, an experimental open-source “Windows 9x Subsystem for Linux” that runs a Linux shell from MS-DOS inside Windows 95 or 98. The Codeberg project patches user-mode Linux, targets i386, and is explicitly rough early work for retro-computing hackers.
// ANALYSIS
This is less a practical dev environment than a glorious systems-programming stunt, but it is technically interesting because it pushes modern Linux assumptions into one of Windows’ strangest legacy eras.
- –The project reportedly uses a patched Linux 6.19 user-mode kernel, cross-compiled for i386 with musl and integrated with Open Watcom.
- –Running Linux tools from a Windows 9x session via a `wsl` command makes the joke land, but the architecture is the real story.
- –The author describes it as messy work in progress, so treat it as a hackable proof of concept rather than stable infrastructure.
- –For AI developers, the relevance is indirect: it is low-level open-source tooling, not AI tooling, but still catnip for people who care about runtimes and OS boundaries.
