   I've never heard of a "Dataproducts interface" but I've seen dozens of
Dataproducts S-100 cards including printer interfaces. They do, or at
least did, show up regularly in the scrap places around here (Florida).
Usually there are some name brand S-100 cards with them. I pick up the
standard brand S-100 cards but not the Dataproducts ones since I have no
docs for them. I've never seen the machines that the cards come out of so I
have no idea about them.
