Internal Atari documents circa 1983 regarding development of a PAL to SECAM converter for the Atari 600XL and 800XL computers. The project code name was Yvette.
These documents were loaned to me for scanning in 2021 by former Atari employee Dan Kramer.
According to Dan, the Yvette project was managed by Paul Fung, a consulting engineer. It was to be an external converter device. Dan doesn't know if the project reached the point of being fully operational to the SECAM standard.
