NuBus expansion slots

NuBus was a 32-bit parallel computer bus architecture, characterized by its processor independence, synchronous operation, and revolutionary auto-configuration (plug-and-play) capabilities. Developed at MIT and later standardized as IEEE 1196, it gained prominence as the primary expansion bus…

Problem solved
NuBus was created to address the significant challenges posed by older expansion bus architectures, which were typically tied to specific CPU architectures, suffered from performance bottlenecks, and required complex, manual configuration (jumpers, DIP switches) to avoid resource conflicts. It aimed to provide a high-performance, processor-independent, and self-configuring expansion solution for advanced workstations.
