IBM Enhanced Keyboard with TrackPoint II

More about this type of keyboard...

The IBM Enhanced Keyboard with TrackPoint II (or simply IBM TrackPoint II Keyboard) was a variant of the IBM Enhanced Keyboard with an integrated TrackPoint II pointing stick. Also branded as the Lexmark Classic Touch Keyboard with Pointing Stick, the Model M13 is perhaps the most famous standard Model M variant with the most useful integrated pointing device. Production for the Model M13 was split between Lexmark and Maxi Switch, with Lexmark mostly producing beige ones and Maxi Switch producing the more infamous black ones although both produced the other colour on occasion as well. Model M13s had several distinctive features, including noticeably stronger chassis case texturing, PS/2 pass-through port for mice on the back, and the use of pad-printed legends for the black variant due to the contrast limitations of dye-sublimation.
