This episode is about analog computers, which are computers that compute using a physical model of a real system, often using analog electronic devices. Our guest is Bernd Ulmann who runs the Analog Computer Museum near Wiesbaden, Germany. In the episode we talk about what analog computers are (mechanical, electronic, digital), how they are programmed, what they are used for and why they should (and will?) be used in modern computing as well. We close the episode with a short discussion of the VAX and the AN/FSQ-7, both computer systems near and dear to Bernd.
