So I've contacted MK Seiko, and you are right: the card was used to control the 'Art Sign' LED display, a general-purpose information board for stores released in 1990. Unfortunately, they couldn't provide any additional information or instruction manual.

Oh cool! Frankly, I'm surprised they still know about the product at all, so it's quite understandable they don't still have any documentation or equipment laying around. Maybe buried in some file cabinet or closet that everybody has forgotten about...
