Putnam’s functionalism is another (earlier) than that of Lewis. It is directed against the computer model of the mind. It believes in the idea of a "program of the mind" which might be realized materially somewhere else already, e.g. in the totality of a rail system with freight transport.
Lewis: his functionalism has nothing to do with that. But according to him, it might well be that machines cannot have a mind a priori.
