This is an official, vintage, 1994 Apple Desktop Bus Mouse II M2706, a classic piece of Apple's illustrious history. With its unique trackball design, this piece offers a tactile and responsive experience, catering to those who appreciate the vintage precision of a physical trackball over a touchpad. This mouse is for vintage Macs and Power Macs and is compatible with any beige colored Mac except the 128K, 512K and Plus models. Appears to be in working condition and very clean - though I have nothing to fully test it on. Inspection available as is local pick up.
