    In five hours [the ILLIAC] can complete problems which would take the working lifetime of a skilled mathematician. Shown working with it are Miss Ramona J. Russell, computer operator, and Jack O. Neuhaus, research assistant in Psychology." The ILLIAC I was the first computer which was built and owned by a university. It went online on September 22, 1952. It had the same computing power as a handheld calculator would have today, but it weighed five tons! It was 10 feet long, 2 feet wide and 8.5 feet tall. It had a 5K main memory and a 64K drum memory. In January 1948, the University of Illinois Board of Trustees gave $150,000 for the construction of a computer. John Von Neumann from Princeton University recommended UI build its own computer. Once the ILLIAC I came online, it was only available for use eight hours a day, but eventually, it was made available twenty-four hours a day, six days a week. It was eventually dismantled in 1962. The ILLIAC I had more computational power in 1956 than all of the computers at Bell Labs. Input to the computer was only possible through five holed paper tape at 100 characters/second, while output was at 60 chars/second or by Cathode Ray Tube Display. In the late fifties, IBM cards were added as input/output devices. More information about the ILLIAC I can be found at http://ems.music.uiuc.edu/history/illiac.html.
