GO Corporation – Getting Started with PenPoint (Version 1.0)

Getting Started with PenPoint is the introductory tutorial guide GO Corporation published for version 1.0 of its PenPoint operating system.¹ GO Corp., a privately held company founded in 1987 to develop pen-based computing technology, had announced PenPoint on January 22, 1991, presenting it as the only general-purpose operating system designed for mobile computers operated by a pen instead of a keyboard or mouse.² A developer release went first to software vendors, followed by a phased beta program that GO laid out as the path to a production release of PenPoint 1.0.³ That commercial release arrived on April 16, 1992, the point at which the finished operating system — and the end-user documentation bundled with it — became available.⁴

The guide introduces the Notebook User Interface, PenPoint's central organizational structure, in which a notebook with a table of contents replaces files and directories and the user interacts instead with "documents" identified by page numbers.² Its opening lessons use the Notebook Table of Contents to show how to turn to a document and move between sections of the Notebook.⁵ Later lessons cover PenPoint's gestures, the pen strokes that issue commands, beginning with the tap used to select an item or activate a control.⁶

Preferences such as the user's handwriting style are reached through PenPoint's Settings notebook, which the guide demonstrates step by step.⁷ For the commercial release GO had developed an entirely new handwriting recognition engine, GOWrite, drawing on a database of more than 700,000 handwriting and gesture samples and tuned for "walk-up" accuracy that required no training.⁴ GO designed short tutorials of this kind as "Quick Start" documents meant to get a user productive with PenPoint in ten minutes or less, and bundled them with the operating system.⁴

PenPoint had drawn industry recognition before it shipped commercially, winning PC Magazine's Award for Technical Excellence in the Standards and Operating Systems category in October 1991.⁸ The guide closes with a glossary defining PenPoint's core terms — among them application, bookshelf, document, gesture, and Table of Contents — for readers new to the system.⁹ It was produced by GO Corporation at its offices at 919 East Hillsdale Boulevard in Foster City, California.¹⁰
