How much did ENIAC weigh?

ENIAC, which stands for Electronic Numerical Integrator and Computer, was one of the earliest electronic general-purpose computers, and it weighed around 30 tons. This immense weight can be attributed to the vacuum tubes, wiring, and metal cabinets that made up the machine. The design of ENIAC was quite expansive, comprising various components, which included numerous panels and modules interconnected to perform calculations.

The significance of its weight reflects the technology of the time, as computers were largely composed of physical hardware not only reliant on vacuum tubes but also needed robust support structures to manage that substantial weight. Subsequent advancements in technology have dramatically reduced the size and weight of computers, but ENIAC remains a historical benchmark showcasing the early era of computing.
