Hi,
Like you mentioned, the mininum requirements to use the driver is LabVIEW 7.0. As you probably know National Instruments does not maintain or support this driver. My suggestion would be that you try to post this on the DAQ/GPIB discussion forum to see if another customer has developed the driver for LabVIEW 6.1
Warm regards,
