This, Joel, is a correct description of the amiga mouse, and the reason it 
needed all 9 wires in its fairly heavy cable.  That mouse set the standards 
against which ALL other mice were judged in its day.  It was both dead 
accurate, and as real time at any movement speed as you could get.  The lag in 
a serial mouse with its 2400 baud update speed can and will eat your lunch at 
times as your hand will move it correctly, but you must wait to see the 
pointer itself stop where you wanted it, and then push the button(s).  This 
made a LightWave application about 1/3rd as fast to do something on the much 
faster pc's of the day as it was on an 68040 equipt amiga.
