FERMIAC

FERMIAC is an analog computer that is able to generate pseudo-random numbers, random looking but with a meaning. If the user asks for numerical data on events, like the change of the price of gasoline shares in the stock market, they just need to input a few numbers and they will get a chart of the price fluctuations. Unfortunately, creates massive amounts of heat and radiation when in use since it was used to help create fission bombs during the Manhattan Project.
