Xinu

Xinu Is Not Unix (Xinu, a recursive acronym), is an operating system for embedded systems, originally developed by Douglas Comer for educational use at Purdue University in the 1980s. The name is both recursive, and is Unix spelled backwards. It has been ported to many hardware platforms, including the DEC PDP-11 and VAX systems, Sun-2 and Sun-3 workstations, Intel x86, PowerPC G3, MIPS and AVR (atmega328p/Arduino). Xinu was also used for some models of Lexmark printers.
