A Spanish museum built a Cray-1 replica powered by 30 old Mac minis

The Museo de Historia de la Computación in Spain has created a replica of the 1976 Cray-1 supercomputer using 30 old Mac minis. The exhibit, built to celebrate the 50th anniversaries of the Cray-1 and Apple's founding, preserves the appearance of the original machine without replicating its internal hardware.
