MorphOS
Order of the butterfly
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 Amiga series of computers.
