Northstar HSIO 4 port serial board

[S100-Fun]

Does anyone have any information on the Northstar HSIO 4 port serial board?
I have checked some of the sites on line that have board information on all of the different manufactures of S100 board, but no luck.
Thank You for your help

Perhaps its a bit late, but I have the manuals and a couple of boards.
