Those that are not directly related are included here for completeness and because there are still things to be learned from their study. The underlying assumption of this research was that reductions in price and technological advances in computer hardware will soon make it feasible to put many CPUs on a single chip. This , in turn, will make it possible to create systems with hundreds of computers per user. Amoeba is a client server, object based, distributed operating system. Amoeba is based on a micro kernel design in which each processor runs a very small set of common routines.
Users access the system through X window based workstations or terminals.

Thus it is important to provide operating system facilities that are appropriate to the application. Such systems can be customized by replacing or providing additional servers that implement the desired policies while making use of existing mechanisms provided by the micro kernel.
