A list of platforms (computers, devices) that we find interesting as potential target for HelenOS. The devices which are open or at least Linux-based, should be reasonably hackable. Many believe that we should primarily focus state-of-the-art platforms instead of porting HelenOS to interesting ancient machines. However, supporting ancient machines, if time permits, can be used to demonstrate solid software design and openness.
