"SF looks towards an imaginary future, while fantasy, by and large, looks towards an imaginary past."

| Positronic Brain | ||
| A computer CPU with the capacity to rival a human brain. |
| By exact count, there are seventy-five thousand, two hundred and thirty-four operations necessary for the manufacture of a single positronic brain. |

Here's another quote:
Compare to the Laminated Mouse Brain Computer from Think Blue, Count Two (1962) by Cordwainer Smith, the neuristor from The Moon is a Harsh Mistress (1966) by Robert Heinlein, the artificial brain from The Metal Giants (1926) by Edmond Hamilton and the Thorsen memory tube from The Door Into Summer (1956) by Robert Heinlein.
Thanks to Alex Mair for contributing this item.
All that had been done in the mid 20th century on "calculating machines" had been upset by Robertson and his positronic brain paths. The miles of relays and photocells had given way to the spongy globe of platinum iridium about the size of the human brain.

''... major cities of Earth have free electrical power conveniently processed from their own noise.'
'The appearance was enough like a giant witch's broom to justify the nickname.'
'A vast circle of scarlet stars came up into the greenish desert dusk.'
'He had constructed an organ, a brain, of metal, entirely inorganic and lifeless...'
'I shall never forget the sight... when the yellow gleam of the precious metal appeared under the star dust.'
Oh, and now I suppose someone will develop the robotic porch pirate.
'This thing will start at one end of ...a house and build it complete to the other end, following drawings only.'
