The first electronic (i.e. non-mechanical) computer was the Atanasoff-Berry computer (ABC) and was about the size of an office desk. It was not programmable and was dedicated to a single task: solving linear equations.

The Colossus, used in WWII for code-breaking by the Allies, was programmable by switches and patch cords, but again was dedicated to a single task. It was the size of an office room.
