Help me out here...!
I was going to cite a sci-fi story as Prior Art, but I can't remember the name of it (or even who wrote it, but it might have been Philip K Dick or Roger Zelazny) and I've not found it by searching :-(
IIRC it concerns someone who has lost an arm and had a cybernetic replacement, however suffers what would later be described in the Cyberpunk RPG as "Humanity Loss". He tries to get the surgeons to replace the rest of his body but they refuse, so he locks himself in a room with a computerised surgical device intending to carry out the procedure on himself.
The scientists stop him by hooking a lab tech up to a device which remotely controls the arm to punch himself on the chin (decapitating him!) and the arm is then connected to a Doctor who ends by saying something like "What miracles I shall perform..."
So can anyone remind me what the story is and who wrote it?
