I used to work on/with systems that used those type cards. You had a overly large pc case that would accept 8 or more cards. The outputs of each card would connect by loooooong cables to a monocrome terminal on user's desk. They would run text/field based apps like word processing and spread sheets as if they had a full pc at their desk. If I recall, it was a bit cheaper to use this setup than to put a box at everyone's desk. The last ones I remember came with CGA color.
I like the seller's comment saying that more photo's cost money. Yeah right, like you can't email for free. What's he doing? Developing 8*10 glossys in his own dark room? :-P
