    I’m sorry to ruin your story, but before semiconductors we used vacuum tubes to do the same stuff.

    (Well, they sucked in many ways: they were bulky, heavy, slow, fragile, and hot. But they could do logic gates and everything.)

      Right on, I forgot about all those multivibrators they made with vacuum tubes and such.
