Oh yes, you're right! I need to use this "old" card because a program traditionnaly used here was made using this card and it has to run on a 486 computer for timing reasons... I also use that great NI usb-GPIB card for some other project in combination with python (pyvisa), it runs like a charm!
Coming back to the STD 8410
Well I don't know how you did find this webpage with the driver! What's your secret? I couldn't figure out the download page there (at least I didn't managed google to tell it to me!).
It seems gpibv306.exe is the right file! Now I try to run to see if I could make it work!
Big thank you!
Emmanuel.
