The Honeymoon Machine

Civilian scientist Jason Eldridge runs Magnetic Analyzer Computing Synchrotron (MACS), a vacuum tube computer aboard the United States Navy ship USS ''Elmira''. He and his friend Lt. Ferguson Howard realize that, by using MACS to record a roulette table's spins over time, the computer can predict future results. Howard and LTJG Beauregard Gilliam check into a Venice casino's hotel dressed as civilians with Eldridge, defying Admiral Fitch's order that naval officers on shore avoid the casino and wear uniforms. They plan to use signal lamps to communicate with a confederate manning MACS on the ''Elmira''.
