==On-The-Ball and On-The-Ball Plus==
The On-The-Ball is similar to the IBM Model M5-2. Whereas the M5-2 was based on the 1391401 and had a detachable SDL cable, the On-The-Ball is based on the Customizer. The On-The-Ball Plus had an FSR Trackpoint in addition to the trackball. Rubber dome versions of the On-The-Ball are very common (part number 96U1114), so one should take care if they are buying a second hand one. Given that the standard On-The-Ball is based on the Customizer, it is available in the same variations - such as the choice of PS/2 or USB, 101/102-key layout or 104/105-key, and white or black with grey keys. The On-The-Ball Plus is quite rare, it entered production in 2000 and ceased to be available in 2008.
