I specialize in researching older videogames. Another person interested in this subject recently sent me this article from 1879 about a man from Philadelphia who succeeded where Charles Babbage did not - mainly in building a perfectly operating Tic-Tac-Toe automaton.https://archive.org/stream/journalfranklini107fran#page/n17/mode/2up
The device was never patented, but the instructions appear detailed enough that someone could build it. I lack any engineering skill, but have some degree of familiarity of the technology thanks to studying Charles Babbage.
I was curious if anyone here was familiar with the types of mechanism used and would be interested in talking with me, perhaps at the next open house. Any other comments here are appreciated as well!
