Konrad-Zuse-Zentrum für Informationstechnik in Berlin-Dahlem

Konrad-Zuse-Zentrum für Informationstechnik Berlin

founded in 1984 by the Senate of Berlin:

“Gesetz über das Zentrum für Informationstechnik (ZInfG)”

“Dual Concept”

SC: scientific computing

CS: computer science & computer services

~200 staff members inclusive students and regular guests

The Roots: Konrad Zuse

1938: Zuse Z1, first programmable mechanical computer

destroyed in World War II

1941: Zuse Z3, first programmable electromagnetic computer

2000 relays, 1/3 Flop/s

Z1 has many features of a modern computer:

• freely programmable• separate memory• control unit with

micro sequencer• floating point arithmetic
