The ICON was a computer built specifically for use in schools, to fill a standard created by the Ontario Ministry of Education. They were widely used, mostly in high schools in the mid- to late 1980s, but disappeared after that time with the widespread introduction of PCs and Apple Macintoshes. They were also known as the CEMCorp ICON, Burroughs ICON, and finally Unisys ICON when Burroughs and Sperry Corporation merged to form Unisys in 1986. The machine was also known as the bionic beaver.
