I remember reading in my youth a science fiction story (I think it was a short, otherwise I would have more details) about a ship that ran on people's brains (multiple brains) the ship saved the bodies in storage with the heads stuffed with electronics, so that when the people were to be "rewarded" or interact with people from other ships the ship could give them remote control of a body (brain still wired into ship)
I feel like there was piracy involved.
well I know i read it between 1988-1992 but i think the book is earlier than that because of the cabinet i pulled it from in my dads basement. it was filled with Sci-Fi from the 70's through the 80s
I also remember the characters being allowed in the story to use their bodies to sit at a formal dinner, (I believe on the ship that their brains were running) To host a guest (maybe from another ship?)
