Ferranti Mercury

Commercial Computer

The Mercury was an early commercial computer from the mid-1950s, built by Ferranti as the successor to the Ferranti Mark 1, adding a floating-point unit for improved performance and increasing reliability by replacing Williams tube memory with core memory and using more solid-state components. It used roughly 2,000 vacuum tubes and 2,000 germanium diodes, and nineteen Mercuries were sold before Ferranti moved on to newer designs.
