I first visited New York City when the USS Randolph docked there in 1960. Eventually I went to work for a company that had systems installed at various locations in Manhattan, and I would sometimes spend days at a time in the city. I usually took along my camera, and apparently one day I decided to burn through a couple of rolls of film and capture some interesting geometry. It’s all black and white, which is how Manhattan looks best.
For starters, here’s about the only interesting street scene from that session:
Then a bunch of architectural shots. I eliminated most repetitions, but there are some duplicate themes:
Finally, the reason I was spending so much time in NYC. The system was called Trace, and it was about 40 feet long. You put a stack of bank checks or similar documents in a feeder, and Trace would suck them up at 20 or more per second, read them, sort them, and stack them into separate bins. Computers would crunch the data. It was a really big deal 40 years ago before point of sale (POS) systems became available. Back in the old days retailers would capture an imprint of your card and forward a copy to the card company. At the card company’s processing center the operator would set the feed to 40 per second.
The photo below shows part of the Trace document path of a system installed at a major bank on Wall Street.
