The Atari 800 XL, PAL version (model officially sold in France)
Remark #1: The serial number sticker was removed by a 13yo technician, during a space bar repair operation, because he believed the sticker was hiding a screw. Eventually, he was proved wrong but the serial number sticker was destroyed in the operation. I still regret it today.
Remark #2: The French sticker reads "Si cet appareil est directement connecté sur la prise d'antenne de votre téléviseur, il est interdit d'utiliser un dispositif de raccordement permanent non homologué. En cas d'infraction, l'usager s'expose à des poursuites."
, which could be roughly translated as "If this device is directly connected to the antenna plug of your television set, it is forbidden to use a non homologated cable for a permanent use. If case of malpractice, the user can be sued."
