It's a kensington turbomouse 4.0, vintage 1991.  Nice smooth, big, 
trackball, and needs a special driver under macos for the right key to 
be anything but annoying--tends to become a repeating right-arrow until 
you hit escape if you happen to brush it.  Under bsd, it seems to 
generate a right arrow.
