Wolfgang Köberer doesn't have much time to follow NavList message traffic anymore. He sent a couple of files on the Willis machine which I am posting here on his behalf. One or both of these may already have been referenced.
Some of you will remember that Wolfgang is an expert on these calculating machines, and he did a presentation on the great variety of such devices over many decades, which all failed in the "market", at a little conference in Greenwich back in 2012. A number of NavList members were present at that conference including me, David Pike, and Geoffrey Kolbe (sorry for leaving anyone out! please say so if you remember Wolfgang's presentation).
