Help needed identifying 8-bit ISA mit 15-pin D-Sub Connector

[jens.hafner]

Dear all,

I just obtained a IBM PC/AT 5170 which had a special 8-Bit ISA card in it. The card has a 15-pin male D-Sub connector on the slot cover. Several ICs with an IBM label on it and a part numbers that would fit the IBM scheme. If I enter the part number into google, I get all kind of contradicting information on this card, incl. it is a network adapter, a LCD-Display controller or an advanced emulation card. All prints that I could find on the card are below. Does anybody know what card this is?

That is a IBM 5250 TwinAx Terminal Emulation card. The DA-15M goes to a TwinAx dongle.
