Hello, I'm new to this list as I just recently bought a Nikon Coolscan LS-20. I have a NT 4.0 system with Tekram 390F Ultra wide SCSI Controller. I added the LS-20 to the 8-Bit end, where CD and CD-RW are connected. IDs, active terminations and so forth are okay. Installation of Nikon Scan worked without any error message. The NT SCSI-Tool shows the controller and all connected items. Paint Shop shows the TWAIN Source. But when I start the Nikon Scan Tool, it tells me "connecting to the scanner" and then hangs! Any hints? Anyone who had similar problems? Anyone with LS-20 and non-Adaptec SCSI controller?? llap Jochen -- "Computers are not intelligent. They only think they are."
