More about this type of keyboard...
The Unicomp On-The-Ball Plus was a specialised combined variant of the Model M5-2 and Model M13 keyboard designs that sold for only a short time. The trackball module was the same 25mm module always used on Model M5-2s, however, the pointing stick was Unicomp's own force-sensitive resistor implementation like Unicomp-era On-The-Point Model M13s.
