Hollerith cards on my system right now with an optical card scanner. Data

Can you tell us more about what you're doing? Is this a commercial
card reader, or something you built yourself? I was daydreaming
the other day about reading punched cards using a flatbed scanner.
Software to "read" them could be quite simple, and could easily
adapt to the various card geometries. Or you could even make a
reader from a feed-roller and an old hand-held scanner. I find
using today's gizmos to rescue yesterday's data quite interesting...
