The computer centre from the Sachsenwerk in Dresden is part of a system that was only shut down in 1993. It played a role in GDR computer history and a part in the success story of a major computer system. The Einheitliches System Elektronischer Rechenanlagen (standardized system of electronic computers) is the functional replica of an IBM computer: ESER 1055 is compatible with the 370/155 in terms of hardware and software alike. These computer systems were built until well into the 1980s. Photo: Jan Braun, HNF
