The Atari 400, PERITEL Version (for SECAM countries)

The computer

The documents and hardware I own don't give me any clue about the release date of this PERITEL Atari 400 computer in France, but I'll assume it was released alongside its sibling, the PERITEL Atari 800. To read about the PERITEL adaptor and the resulting output, I invite you to visit the PERITEL Atari 800 page. I will not duplicate information on this page describing the 400 model.
