This keyboard is similar to standard 1391401 keyboard, but has integrated trackpoint pointing device, additional drainage holes on bottom of keyboard to reduce spill damage, includes set of 4 trackpoint covers (2 red and 2 black).
Utilizes Unicomp’s 1999 “force sensing resistor” trackpoint technology, in contrast to proprietary IBM 1995 – 1998 “strain gauge” trackpoint design.
