Nukernel
NuKernel is a microkernel which was developed at Apple Computer during the early 1990s. Written from scratch and designed using concepts from the Mach 3.0 microkernel, with extensive additions for soft real-time scheduling to improve multimedia performance, it was the basis for the Copland operating system. Only one NuKernel version was released, with a Copland alpha release. Development ended in 1996 with the cancellation of Copland.
