Bicomm – Bielefelder Computermuseum

About the museum

The Bielefelder Computermuseum, or Bicomm for short, first opened to visitors in 2013. It began with the calculator and home computer sections. The arcade area was built between 2016 and 2018 and now comprises more than 40 machines; the game console section followed in 2019 and 2020.

In 2022 the museum acquired an extensive collection of electronic experimentation kits, which it now displays as more than 400 kits from manufacturers including Kosmos, Philips and Braun. A collectors' meeting of the Internationales Forum Historische Bürowelt in July 2025 also greatly expanded the stock of mechanical calculating machines.

The museum focuses on the years 1970 to 1985, when calculators and computers became small, affordable and part of everyday life. Across more than 400 square meters, many devices are working and may be tried out. Special features include six working IBM machines of the 5110 and 5120 series, a Kienzle taximeter with the Intel 4004, the world's first microprocessor, and four Nürburgring machines by Foerst. According to the museum, its more than 1,200 desk and pocket calculators make up probably one of the largest calculator collections in the world.
