The Pixar Image Computer was a graphics designing computer made by Pixar in May 1986, intended for the high-end visualization markets, such as medicine. The machine sold for $135,000.00, but also required a $35,000.00 workstation from Sun Microsystems or Silicon Graphics. The system did not sell well, and by 1987 Pixar only had a handful of buyers. In an attempt to gain a foothold in the medical market, Pixar donated ten machines to leading hospitals and sent marketing people to doctor's conventions. However, this had little effect on sales, despite the machine's ability to perform CAT scans and show perfect images of the human body. By 1988 Pixar had only sold 120 Pixar Image Computers, and eventually sold the machine to Vicom for $2M.
