I lived in France for a few years around the turn of the millennium and picked up a Minitel 1 cheap at a local flea market. I set it up in the living room as a GUI for a sound system controller connected to a Linux box, playing MP3s. I don't remember the details but there was something odd about the serial port... funky voltage or baud rate or something. It seemed very retro at the time... the design exuded 1970s style in some way (it had some style in common with the Poly-1 computers from my high school in New Zealand, originally released around the same year, 1981). Sadly I left it behind! The keyboard was frankly terrible. Vive l'azerty.
