I think these DEC ones are 13 x 16 pages per fiche. I was assuming they
were A4 pages, but maybe they're one of the US formats (would make more
sense for DEC I suppose).
Doing some scribbling I think I came up with a 1200dpi scan being
equivalent to about 30-40dpi equivalent against a real-life A4 page -
given that I normally scan A4 sheets at 300dpi that'd require a scanner
capable of something around 9600dpi.
Maybe my calculations were off though :)
