This would be a great prop for time travel scifi movie. Protagonist travels to 1991 and tries to convince scientist to help him. When asked for a proof, shows Gray C90 Wristwatch. "Our real computers are different, but I show you this because it does not pollute the timeline."
My premise for a time travel movie is very simple. 1. Buy a book on probability. Work through the practice exercises. 2. Time travel back to a time before the laws of probability were invented or taken seriously. Pre-1600's would be a good guess. 3. Become a gambler. 4. With the riches that will soon be pouring into your pockets, acquire resources and transform history.
Buy two large pizzas, cheese and 'supreme'.
Be earlier than that guy.
