Jaquet-Droz's 1770s Writer is said to write up to 40 programmable characters

A post says Pierre Jaquet-Droz built the Writer in the 1770s and that it contains more than 6,000 parts. It describes the automaton writing up to 40 programmable characters and says it still works and is kept at the Musée d'Art et d'Histoire in Neuchâtel. The author likens it to “an 18th-century large language model.”
