List of vacuum tube computers

Vacuum tube computers, now termed first generation computers,[1] are programmable digital computers using vacuum tube logic circuitry. They were preceded by systems using electromechanical relays and followed by systems built from discrete transistors. Later entries in this list may have been built using transistors in addition to vacuum tubes.

This is a list of vacuum tube computers, arranged by date put into service:
