Uutta käyttistä tekeillä vanhaan kunnon Amigaankin.

Serena OS is what you get when modern operating system design and implementation meets vintage hardware like the Amiga computers. It is based on dispatch queues rather than threads, supports multiple users, is inspired by POSIX, yet retains its own character, is strongly object-oriented in terms of design and implementation and prepared for a cross platform future.
