Combi-Mouse PS/2/Serial Version (250-2001) Features Faxback Doc. # 5138 The Tandy Combi-Mouse is a two-button pointing device for personal computers. It is designed to interface with either a serial or PS/2-compatible mouse port. This is an opto-mechanical mouse featuring 400 dots per inch resolution. The user moves the mouse over a desk top -- or any flat, even surface. This causes the ball under the mouse to rotate. The ball movement is translated into X and Y movements inside the mouse by two perpendicular shafts in contact with the ball. The cable attached to the mouse has a 9-pin D-sub FEMALE connector. This is used to connect with the 9-pin serial port on most personal computers. Also included in the package is an adapter (9-pin D-sub MALE to 6-pin MALE mini-din) for connecting to personal computers with a dedicated mouse port (such as the IBM PS/2 models). Just attach the adapter to the 9-pin D-sub connector and plug the 6-pin mini-din into the computer's mouse port. There is not a need to open the mouse. (abo-07/30/93)
