-was at the center of a patent dispute relating to the invention of the computer link
-
-was a room-sized, relay-based calculator
-had a fifty-foot long camshaft that synchronized the machine’s thousands of component parts
-sed to produce mathematical tables but was soon superseded by stored program computers link -
-was designed to break the complex Lorenz ciphers used by the Nazis during WWII
-reduced the time to break Lorenz messages from weeks to hours link -
