John Sladek SF Gateway Omnibus: The Reproductive System, The Muller-Fokker Effect, Tik-Tok

THE REPRODUCTIVE SYSTEM: Wompler's Walking Babies aren't selling like they used to, so the company develops Project 32, producing self-replicating mechanisms designed to repair inter-cellular breakdowns. But then the metal boxes begin crawling about the laboratory, feeding voraciously on metal and multiplying...

THE MULLER-FOKKER EFFECT: Bob Shairp - a writer and dreamer - has agreed to be a guinea-pig in a military experiment to find out if his personality can be turned into data and stored on computer. But a computing error quickly destroys Shairp's physical body, leaving his mind stranded in an encoded world. Can the process be reversed?

TIK-TOK: Something has gone very seriously wrong with Tik-Tok's 'asimov circuits'. They should keep him on the straight and narrow, following Asimov's First Law of Robotics: 'a robot shall not injure a human being, or through inaction allow a human being to come to harm.' But they don't. While maintaining the outward appearance of a mild-mannered robot, albeit one with artistic tendencies and sympathy for the robot rights movement, Tik-Tok's real agenda is murderously different. He seems intent on injuring - preferably fatally - as many people as possible. Almost inevitably, a successful career in crime and general mayhem leads to a move into politics and Tik-Tok becomes the first robot candidate for Vice President of the United States.
