Dominique, Nice to see your machine working so well! I like how it lights up from the inside. To connect it to a computer, you could simply get a Volpe board that does the Baudot 60 mA loop to ASCII RS 232 conversion for you, or build one yourself like I did. Info on both here: https://www.curiousmarc.com/mechanical/teletype-model-19#h.p_2ltO4LwPtuZR Matc
