The CDC 6600, built by Control Data Corporation, is remembered as the first supercomputer and the modern ancestor of supercomputing data centers today. The system was designed by Seymour Cray for the Lawrence Radiation Laboratory, had a clock speed of 100 nanoseconds, and was first to include a CRT console - which made the computer famous for displaying the very first monitor-shown video games such as Lunar Lander. The design of the CDC6000 was based on a 40 MHz central scientific processor with ten supporting peripheral machines that ran what would later be known a a reduced instruction set (RISC). With a sustained performance of 1 MFlops (peak 3 MFlops), it was by far the fastest computer of its time and remained in operation until 1977. The CDC 6600 originally sold for $8 million, or more than $60 million in today's value.
