  1. It doesn’t necessarily have to have storage or be programmable to be a computer. A computer (by definition) is a device that computes, so even a simple 4 function calculator can be considered a "computer".

  2. @K Sharf: Of course it’s a computor! Look at all the electronicals! Anything with that many electronicals must be a computor. The Scientific Law of Science demands it! 🙂

  3. Nearly identical to my group’s term project in an EE course I took in ’88. ‘Cept ours was wirewrapped.
