A long time ago, I use to work on a very old analog computer made with tubes. It was 120 separate op amps that had a +-100V swing. Yeah, if you got on that “One” it was very painful.

The room-size computer used 5-foot-long mercury-filled tubes for the main memory. It relied on 3,000 vacuum tubes , arranged on 12 racks containing just over 140 chassis, for computational operations.
