The computer

The SECAM Atari 600XL was announced but never produced; the SECAM Atari 800XL was the only model available in France. Unlike the PERITEL Atari 800, the video signal available on the PERITEL/SCART connector of the SECAM Atari 800XL is not limited to 8 but to 128 colours.

This SECAM model available in Q4 1984 drastically reduced the total cost of owner ship, compared to a PAL Atari 800XL with RGB video converter.
