MorphOS
MorphOS is a lightweight, highly efficient and flexible desktop operating system. It includes primarily proprietary as well as open - source components. Its many features range from a modern exceptionally customizable graphical user interface, which can utilize 3D hardware acceleration, to a high-performance Just-in-Time compiler that emulates the 68k family of processors and thereby allows to transparently execute legacy applications developed for the Commodore Ax00 series of computers.
