Yes, for a generic, now 20+ yo 3 button ball mouse, working against a 2nd 
piggy backed set of 6551 chips in an rs232 pack, making a dual pack out 
of it. Unlike the spastic stock mouse, its 100% real time and click hits 
are exactly where its at. Works very well with multivue stuff. Icnedit 
even uses all three buttons. How well it works with modern optical mice 
hasn't been tested here. I also moved the output cable to the rear of my 
mouse because the front exit messed with the clearance to the multipak, 
much nicer handling with the cable coming out the rear of the mouse and 
hanging over the table edge under the ball of ones wrist. What we need 
now is a usb dongle to serial port adaptor so we could use  modern 
wireless optical mice. That would indeed be sweet.
