In the Orson Scott Card short-story "Salvage" (1986), an unspecified disaster has impacted (at least) the Southwestern United States -- Salt Lake City, Utah, is almost entirely submerged under water. The main character of the story makes a living salvaging old computers and other electronics. This includes an Atari 2600:
"Lehi never took his eyes off the screen. He jabbed a a button on the black box and twisted on the stick that jutted up from it. A colored blob on the screen split into four smaller blobs. [...] It's an Atari. From the sixties or seventies or something. Eighties. Old. Can't do much with the pieces, it's only eight-bit stuff. All these years in somebody's attic in Logan, and it still runs."
