A vacuum tube computer is a computer system built primarily using vacuum tubes and vacuum tube logic. Vacuum tube switching replaced the earlier relay computers from the 1940s. Vacuum tube computer gained traction during the 1950s through the early 1960s. By the mid 1960s transistor computers superseded vacuum tubes.
Overview[edit]

Early relay computers were rather slow - operating at just 1Hz ((or one switching operation each second). They were cheap and readily available due to their widespread use in telephone systems. Vacuum tubes prove to be a significant improvement over electromechanical relays - operating 1000 times faster. However the performance advantage came at the cost of decreased reliability and maintainance. Tube failure was frequent, running hot and burning out rapidly.
