QNX 6.4.1 ported to a new platform as QRV
Claude Code did most of the work porting the 2008-era QNX 6.4.1 operating system, now called QRV, which boots to a shell on 4 CPUs in QEMU.

The full story
QRV is a port of QNX 6.4.1, an operating system from around 2008. The poster says Claude Code did almost all of it. The human started the project, adapted the QNX startup code, guided the architecture, debugged, tested and gave direction.
QRV 0.17 now boots with four CPUs under QEMU and reaches the user-space shell. Next on the list are virtio, filesystems, more user-space tools and reworking the kernel to remove the "big kernel lock".
