Hi All
I have just had a huge DEC Miro Fiche library given to me.
It has the portable (weighs a ton) reader with it.
On trying it out. I found the results were awful.
A good clean of the light path and removal of some disintegrating foam
improved things no end.
That left two issues:
1. The reader was for x 42 but the fiches are x52.
This is not at all unusual. I do have a stock of microfilm reader
lenses, if we can figure out who actually built the reader and which lens
it takes. Is there a name or model on the lens or reader (other than DEC)?
2. The plastic fiche holder consisting of two sheets of stiff and
clear plastic connected together at one end is scratched to hell.
Thin plastic is really unusual here because of the tendency to melt under
the heat of the lamp.
I'd like to work to-wards scanning all of the library into a system.
Anybody know anything about fiche scanners.
This is exactly what my company does (and my previous, now defunct,
employer as well). I have dedicated microfiche and microfilm scanners.
The problem I ran into when trying to scan my DEC microfiche collection was
that the fiche themselves were of very poor quality. Badly scratched and
scuffed, and poor quality duplicates.
Jim mentioned that dedicated microfilm scanners are expensive. He's not
kidding. Used machines tend to start around $5k USD for a low end, heavily
used scanner. New machines are generally $30k at the lowest end. Flatbed
photographic film scanners are much cheaper, but also slower. However,
with some scripting and tools like the ImageMagick library, you can scan an
entire fiche in one pass, then slice up the image into individual pages
accordingly.

Thank you for your kind reply
Reader is:
MICROFICHE READER MODEL SC01-E
SERIAL NO. 4573
MAGNIFICATION 42x
VISIDYNE INC BURLINGTON MA USA
UK model (yes I'm in the UK)
230 VOLTS AC 50/60Hz .75 AMPS

Using my home made but clean fiche holder the few fiches I looked at
seemed OK.
When adjusted for sharp focus the text was clear but a bit small.
