The PenPoint OS was one of the earliest operating systems written specifically for graphical tablets and personal digital assistants. It was a product of GO Corporation. PenPoint OS ran on a number of Intel x86-powered tablet PCs including IBM's ThinkPad 700T series, NCR's 3125, 3130 and some of GRiD Systems' pen-based portables; it was later ported to the Hobbit chip in AT&T Corporation's EO Personal Communicator.[1] PenPoint was never widely adopted.
Developers of the PenPoint OS included Robert Carr, who was involved with the Alto computer at Xerox PARC. He commissioned Dr. Tinker, the naming service company of Mark Beaulieu who generated the name 'PenPoint', using proprietary algorithms.
