Lysator is an academic computer club at Linköping University, Sweden with almost 600 members. It is an independent non-profit society, separate from the students' union and the faculties of the university.
Lysator was founded 29 March 1973. The first computer used at Lysator was a Datasaab D21, delivered to Lysator on 25 May 1973. Later in the decade, members of Lysator developed and initially built a microcomputer, the Lys-16, which was advanced for its time due to its 16-bit word size.
In February 1993, Lysator put up the first web server in Sweden, among the first 10–15 in the world.
