Here we have a Lot of 13 Vintage Mouse/Mice for Computers. These are untested but I have faith most, if not all of them work besides the ones missing their ball. These are being sold as broken/as is due to not testing them and a few missing their ball. Brands include Compaq, Microsoft, HP, CTG, Logitech, and some just names "Serial" (Generic). These are all old mice that have been stored away for awhile, so you will notice some have yellow discoloration. All of them have their plugs (PS/2, Serial, etc) and 2 or 3 are missing the ball. Some models include HP M-S34, M-S30,  Compaq M-S34 and Logitech M-S69. Thank you for looking. Please choose preferred shipping at checkout, I can send USPS Ground or Priority.
