This listing is for a vintage computer mouse.  Made in 1987 by Logitech.  Model 82-9F.  2-button.  9-Pin serial connection.  It is in nice shape and still works properly.  Use the 'super size' feature on the pictures to get a better look.

I offer $6.99 Ground Advantage shipping in the United States and calculated shipping for international buyers. Thank you once again.
