For sale is a vintage Microsoft IntelliMouse TrackBall 1.0, featuring Microsoft’s distinctive white ergonomic design with an integrated trackball and scroll wheel.I originally purchased this mouse new and opened the box, only to discover that it uses a true serial-port connection. I couldn’t get it working with my PS/2-to-USB adapter, so it was put aside and has seen virtually no use.
