The transistor changed the world. It made small, complex, and cheap computing possible. But it wasn't the first attempt to crack the case. There is a long and strange lineage of similar devices leading up to the transistor. In this episode we take a look at two of those devices. First the vacuum tube, one of the first components that made computing possible. Then the cryotron, the first device purpose built for computers.
