I've seen fiche scanners available
commercially (I just did a google search
when this came up a few months ago).

All the ones I found seemed to be $10K+ ...

Back in the early 1990s, I had access to
a fiche printer - i.e. something that would
print an A4 page of whatever the fiche reader
was looking at. No automation (if you
wanted the whole fiche as a set of pages
you had to line it up yourself and hit a button
for each page).

That produced reasonable quality copy.
If I still have any around I'll try to scan
a sample page.

I have no idea how much this thing cost
but it was about the same volume as
three or maybe four 21" monitors.
