Hi John, You may already be aware of it and visited if you've ever been to Chicago, but, the Museum of Science and Industry is well worth a visit if you don't find anything more computing oriented that's more interesting. You can check out their current exhibits and search for computing exhibits at https://www.msichicago.org/explore/whats-here. Any Uber driver will know where it is, but just in case, the physical address is 5700 S Lake Shore Dr, Chicago, IL 60637. There are tons of park area surrounding it, but, at this time of year and with it being right on Lake Michigan, you might need to stay indoors lest you become yet-another ice sculpture! The captured Nazi U-boat, U-505, is now inside its own nice, warm exhibit hall, high and dry, and can be entered for tours, along with its Enigma encryption/decryption machine artifacts on display adjacent to it. The machine, rotors, encryption settings books, etc., are all there, that were captured before the crew could send off a radio message warning that the material had been compromised, and before the sub could be scuttled. All the Best, Jim On Tue, Jan 7, 2020 at 7:30 AM John Herron via cctalk <cctalk at classiccmp.org> wrote:
