2 окт 1968 г. - First computer ball mouse offered by Telefunken. The device named Rollkugel RKS 100-86 is based on "reversing" an earlier trackball-like device (also named Rollkugel) embedded into radar flight control desks, which had been developed around 1965 by a team led by Rainer Mallebrein at Telefunken Konstanz for the German Bundesanstalt für Flugsicherung (de) as part of their TR 86 process computer system with its SIG 100-86 vector graphics terminal.
