Welcome to the forty-sixth issue of De Programmatica Ipsum, dedicated to the subject of Computer Museums. In this edition, Adrian visits four computer museums in Switzerland, Graham reflects about the importance of memory and the role of museums, and in the Library section, Adrian reviews William Aspray's biography of John von Neumann.
