This was my first Logitech device from back in the day! It's model T-CL13 PS/2 Trackman Marble+ trackball 2-button w/ scroll wheel. I loved how unique this was, and still is. I was the first and only owner. The plastic has the aged look but the mouse is otherwise in excellent shape. It uses the PS/2 port which I no longer have a computer with that port to test it with. However, it was working perfectly when it went into my closet aka long term storage. Just trying to downsize and would love to find a great new home for this gem!
