I got this item on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140019385582 Some kind of an 80 col text only card, but the claim is it can work in 160 columns mode!
Look through older issues of Nibble - you'll see ads for this card and the occasional pic of it doing 160 column.
Good luck finding software or docs - I doubt this card was a big seller.
