In the late 1980s or early 1990s I worked in a K-Mart store in Canada (K-Mart is now gone from Canada). At one point I remember they brought in touch-screen Kiosks that displayed some information on merchandise and sales (sort of like an electronic flyer).
I had a suspicion they were running on Amigas and I think I peeked inside through a vent or crack and could see there was an Amiga 3000 in there.
Amigas were also used in the 1980s for driving the graphics of various museum interactive displays - The Ontario Science Centre comes to mind.
