The Amsterdam Subversive Center for Information Interchange (ASCII) was a squatted communication laboratory in the Dutch city of Amsterdam. The first incarnation was formed in 1997 and based at the Herengracht. The lab then moved to the following locations: Jodenbreestraat, Kinkerstraat, Kostverlorenkade, Wibautstraat and Javastraat. ASCII became legalised when it moved into Jodenbreestraat 24 in January 2000, alongside the radical bookshop Fort van Sjakoo, but started squatting again when faced with a 900% rent increase.
