IBM Delivers 7090 Mainframe Computers
The first two IBM 7090 computers are delivered. Along with the faster version, which IBM released three years later, the series was a popular family of transistorized mainframes. Designed for scientific research and large-scale technological application, the computers were used in such projects as the Mercury and Gemini space flights and the Ballistic Missile Early Warning System.
