From the wiki: > The Cyber-72 had identical hardware to a Cyber-73, but added additional clock cycles to each instruction to slow it down. This allowed CDC to offer a lower performance version at a lower price point without the need to develop new hardware. Don’t tell me nobody tried to hack that! > **[CDC Cyber](https://en.wikipedia.org/wiki/CDC_Cyber)** > > The CDC Cyber range of mainframe-class supercomputers were the primary products of Control Data Corporation (CDC) during the 1970s and 1980s. In their day, they were the computer architecture of choice for scientific and mathematically intensive computing. They were used for modeling fluid flow, material science stress analysis, electrochemical machining analysis, probabilistic analysis, energy and academic computing, radiation shielding modeling, and other applications.
