More about this type of keyboard...
The Model M6-1 UltraNav keyboards were an extension of the standard Model M6-1 keyboard that included a trackpad and only used TrackPoint IV. Keyboards such as the IBM SK-8835, SK-8840, and SK-8845 were also the first desktop implementations of a ThinkPad keyboard. Integrated examples of these UltraNav keyboards were largely produced by either Alps or NMB, with desktop keyboards exclusively produced by LITE-ON.
