That's a nice collection of old computer mice! If any of you are fortunate enough to visit CERN in Geneva, there's a mouse museum: http://computer-animal-shel

That's a nice collection of old computer mice! If any of you are fortunate enough to visit CERN in Geneva, there's a mouse museum: http://computer-animal-shelter.web.cern.ch/index.shtml http://computer-animal-shelter.web.cern.ch/index.shtml I'd be particularly interested to see a decap of a PixArt chip (e.g. PAW3515DB). The USB circuitry is included in the same package as the CCD sensor, and I'd like to see how they do that! I also imagine that the die geometry is quite large, because power requirements aren't a major concern, but cost is. It would also be nice to see Ken Shirriff do a historical write up of mice over the generations.
