Inferno Operating System

Inferno was originally developed at Bell Labs (the research division of Lucent Technologies). It is a well-designed, economical operating system particularly suitable for use in networked devices such as advanced video telephones, hand-held devices, TV set-top boxes, and many other embedded applications. Inferno can run in native mode on an embedded system or in emulation mode under many different operating systems. Inferno has many features in common with Plan 9.

Vita Nuova also offers a boxed set w/full source code, binaries, and printed documentation for all supported operating systems (Plan 9, FreeBSD, Linux, Solaris, Windows, Irix, Unixware, and HP/UX) and native hardware (x86, PowerPC, ARM, StrongARM, and MIPS).
