CDC 7600

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The CDC 7600 was the Seymour Cray-designed successor to the CDC 6600, extending Control Data's dominance of the supercomputer field into the 1970s. The 7600 had a 27.5 ns clock cycle and a 65 Kword primary memory using core and variable-size (up to 512 Kword) secondary memory (depending on site). It was generally about ten times as fast as the CDC 6600, and could deliver about 10 MFLOPS on hand-compiled code, with a peak of 36 MFLOPS. When the system was released in 1969, it carried a price tag around $5 million, more as options and features were added.
