In the early 90s, I came across 2 public uses for Amigas.
The first was an Amiga 1000 at the Exploratorium in San Francisco. It was a demo of pattern perception while in motion and then stopped. In later visits, I was unable to find it again. They made much use of early Macintoshes, too.
The second was at Pittsburg's airport. I think they were 1200s used in Kiosks to show maps to the local hotels and car rentals.
