The answer is: Mekel 460XL Microfiche scanner

There are approximately 400 fiche/ft and 100 11x17 images
per fiche or 200 8.5x11 images per fiche.

I have less choice about resolution than I would like. The
400 DPI assumes the minimum magnification, 200 DPI is the
maximum magnification. I'll find out what I get when I get
it. The plan is TIFF with G4 compression which works out
to be half the size of an equivalent PDF and can be converted
to PDF by the consumer if desired. I haven't found a good
way to convert a PDF back into a TIF... We shall see
how good the process works...
