Hi Mark,
I couldn't find the model for this board using the part number or the serial number.
In any case, you can find all the available drivers for a given GPIB hardware and OS combination at:

Given that this is an old board, you'll most likely find support for DOS.
Does the board show a model name?
Hope this helps.
