Just received my (relatively cheaply!) found 9000 (incl. a bunch of film holders, incl. the rotating 120 one, this alone seems to sell for twice of what I paid...) and tried it with vuescan under Linux, using my old laptop's expresscard FireWire card which I had used before with Minolta scanners. Beside a dead cable everything went smooth.
What confused me: trying to scan with the glassless 120 holder, vuescan gives me arbitrary frames when when I select manual cropping. I looked it up and seems I have to fiddle manually with frame spacing and offset. Is there no other way? With the Epson v800 I could just zoom out the whole preview and crop frames manually, this doesn't seem to work. Any better idea?
I am also installing right now a Windows XP virtual machine on this laptop, with the goal to try out Nikon scan, since it seems not that great supported on win10 (which I have installed aside Linux)? But I'm afraid getting the FireWire card pass through to the XP virtual machine might be a mess, let's see... Anyone tried out this route?
