Thanks Micca and Ed. I will PM Micca to see if he has found his old card first but Ed, I may be grateful for you searching through the box.

I don't know if any of the SB series had the expansion socket fitted but the feature disabled - I would have to check model numbers to be certain but I have placed an example picture of a SB16 with the expansion socket here in the hope that it will help identifying suitable cards.
