I have been looking for a book that I read in the 80's but it's probably older. It was about a spaceship from Earth in a very long mission to discover life? I don't remember, but they had been far too long in space without any results, so the crew was on the verge of mutiny.
They land on a planet, home of two super-computers called...? Alpha? Beta? One seemed more advanced than the other, the planet was void of any other life, and supposedly it was forseen that the planet would be struck by a comet, and the computers see the ship as a way to save or abandon the planet before the impact.
At some point one member of the crew is captured by the computers, and it's vivisected in an attempt to get data about humans. Then they "reassemble" the crew member before returning it to the ship, hoping that the humans could "reactivate it" since the computers were unable to do so. Which of course enrages the ship's crew.
The ship was unable to take off for reason that I don't remember and they must fight the computers to save themselves.
Does anyone know what this is?
Thanks, as soon as I read the names, they did ring a bell on my memory. The case it's closed then.
