The DEC ones I've seen are extremely high resolution - from memory, something
like 11 x 13 A4 pages on a fiche around 1" x 1.5".
I'm not sure what the current scanner technology is like, but not so long ago
consumer-grade stuff just wouldn't handle that kind of density; even the ones
coming somewhere close were relying on lots of interpolation rather than raw

Ones that'll handle the resolution are around, but probably with dollar price
tags in the five-figure range. (Again, it was a few years ago I looked into
this, so my knowledge is a little out of date)
Somewhere in there archives there's a whole thread on this (Bletchley has
many, many boxes of DEC fiche)
