I was cleaning out some old books at my office and found this. I bought this new at a tiny Dallas start-up called Soft Warehouse, I think in 1986. Who else is old enough to remember programming in Turbo Pascal?

This artifact, currently on display in our artifact spotlight area, has been linked to our recently acquired Babbage replica. The Italian scholar, Roberto Guatelli, made both of them. Guatelli was a well known maker of historic mathematical reproductions and did several replicas for IBM in the 1960s and 70s. He was especially well known for his Leonardo da Vinci recreations. See The Rotarian, December 1952.
THE ABOVE MODEL IS A REPRODUCTION OF A MECHANICAL CALCULATOR, FIRST DESIGNED BY BLAISE PASCAL IN THE 17TH C. IT WAS COMPLETED IN 1642. THE PRIMARY CONCEPTION WHICH THIS MACHINE INTRODUCED WAS THE MECHANIZATION OF THE CARRY. IT ADDS & SUBSTRACTS DIRECTLY, BUT MULTIPLICATION & DIVISION ARE ACCOMPLISHED BY REPEATED ADDITIONS & SUBTRACTIONS.
