About the Musée Bolo

Musée Bolo Located in Lausanne Switzerland

This museum has the Cray machines that were previously in service at site EPFL. Including a Cray-1, Cray-XMP, Cray-2, T3D and XT4. These photos from an exhibition in 2022 after the restoration using materials from the original maker Naugahyde.

“The Cray X-MP/48, once used at CERN, as well as the Cray-1S, the first Cray supercomputer installed in Switzerland at the EPFL Computing Center, have joined Musée Bolo next to the Cray-2 and the Cray T3D.”

Musée Bolo EPFL – Bâtiment INF, Station 14, CH-1015, Lausanne, Switzerland.

Musée Bolo owns one of the most extensive collection of machines and objects related to information technology and its brief history.

Musée Bolo is managed by the foundation Mémoires Informatiques, a recognized public-interest organization. An association of friends contribute dynamically and efficiently to the maintenance and preservation of the museum’s machines. All are volunteers. Member of the Swiss Museums Association (AMS), Musée Bolo rose to be one of the most important computer museums in Europe. Hosted by the Ecole polytechnique fédérale de Lausanne (EPFL), its presence extends itself today well across the swiss borders, not only to computer lovers, but also to a greater and younger audience faced daily with computing technology and its avatars.
