NI has 4 GPIB cards: Looking at the NI web pages there are 4 distinct, PCI-GPIB interfaces. #1 PCI-GPIB for windows 95/NT/200/XP/Me/98/Solaris http://sine.ni.com/apps/we/nioc.vp?cid=5310&lang=US #2 PCI-GPIB+ http://sine.ni.com/apps/we/nioc.vp?cid=1875&lang=US #3 PCI-GPIB/LP (Low Profile) http://sine.ni.com/apps/we/nioc.vp?cid=10970&lang=US #4 PCI-GPIB for Mac OS 9 http://sine.ni.com/apps/we/nioc.vp?cid=1941&lang=US However, #1 actually does have drivers for Mac OS 9 as well if you read the product description. But if you just search for OS 9 then they send you to the more expensive one. There seems to be no reason that card #4 still exists as an older card. BUT, my OS X PCI-GPIB driver only works with #4. It should work with #1, think the problem is only because it tests for one specific card. If anyone who has one of these small and can tell me the PCI product ID #, I would like to modify my driver so someone could test this. The driver matches against the PCI "name" of "NATI,pci-gpib" Does the smaller newer card with the 5004 TNT chip have the same PCI name? If I had one of the cards, I believe that the Mac OS X "system profile" utility would tell me the name, vendor ID, Device ID etc. I have no idea how to get those hardware properties under windows but if anyone can figure it out, I would be grateful.
