I have the same problem, and I shall look out at the responses to your message.

The main problem with large negatives and a personal scanner + PC , is
that they need a hell of memory, in order to end up with a good final
resolution.

A temporary solution (which I have not yet tried) would be to put the
negatives on a light box, and to capture each frame with a digital camera
secured on a photographic enlarger stand. It is still a mix of antique
dark room and digital age, but this should be helpful for rescuing our old
polaroids, and you have certainly all the gear in your lab...J.J.

Without optical scaling it resolves 3600ppi, with optical scaling (as would be used in a scanner application) this can be set to match whatever the scanner width is - on the 8.5in flatbed scanner configuration that the OP is referencing, it would produce around 1200ppi. ... but it has no effect on the fact that this device will produce a resolution of 1200ppi on an 8.5" scan width. ... that the 10200pixel CCD is only capable of 3400ppi! ...
