I've said this before - but this is just a reminder. I'll be breaking BOTL over time in order to get it into a far better place. Just be patient if you can't reach us! We'll be back
The mouse is older than most of you probably think. In fact, it pre-dates the "personal computer era" by more than a decade. Douglas Engelbart invented the mouse in 1964, and he received a patent for it in 1970 (which expires in 1987). Sadly, he never really made any money off of the invention.
