More on this type of keyboard...
The IBM Enhanced Keyboard with TrackPoint II (or simply IBM TrackPoint II Keyboard) was a variant of the Enhanced Keyboard with an integrated TrackPoint II pointing stick. Also available with Lexmark-only branding, the M13 is one of the more well-known variants of the Enhanced Keyboard. The M13 also came with a PS/2 passthrough port for external mice at the rear, and have noticeably stronger case texturing compared to most other Model Ms. Production for these TrackPoint M13s were split between Lexmark and Maxi Switch, with Lexmark largely producing beige ones and Maxi Switch largely producing the more infamous black ones. Due to limitations with dye-sublimation, black M13s use pad-printed legends on their keycaps.
