There is quite a lot about Leibniz's calculating machine designs on Wikipedia.
I think I found out about Leibniz's bitwise activities in Neal Stephenson's Quicksilver, but he invented the modern notions of both sets and digital logic, according to Wikipedia. He would have used the cards in catalogging libraries.
