Mostly the last choice: as long as a semi-truck trailer.
Early programmable electronic/mechanical computers (ENIAC, Harvard Mark I, Colossus) filled rooms — the Harvard Mark I was about 51 feet (≈15.5 m) long and ENIAC occupied roughly 1,800 sq ft. (Some earlier machines like Zuse’s Z3 were smaller, more cabinet-sized, but the well-known “first” electronic programmable machines were trailer/room-sized.)
