I want to know the answer to the following question:
What computer did Arthur L. Samuel program to play checkers in 1957?
All the background I'm provided with is that "In 1956, the company demonstrated the first practical example of artificial intelligence when Arthur L. Samuel of IBM's Poughkeepsie, New York, laboratory programmed an IBM 704 not merely to play checkers but "learn" from its own experience.". Is that enough to answer the question?
