DNIX
DNIX (original spelling: D-Nix) was a Unix-like real-time operating system from the Swedish company Dataindustrier AB (DIAB). A version called ABCenix was also developed for the ABC1600 computer from Luxor. ( Daisy Systems also had something called Daisy DNIX on some of their CAD workstations. It was unrelated to DIAB's product.)
