This website hosts a browser-based emulator of the Xerox NoteTaker, a portable Smalltalk-78 system developed in 1978. It represents a significant step in the evolution of personal computing, showcasing early concepts of overlapping windows, a bitmapped display, and a mouse-driven interface. The emulation, while not perfectly replicating the original hardware's performance, provides a functional recreation of the NoteTaker's software environment, allowing users to explore its unique Smalltalk implementation and experience a piece of computing history. This allows for experimentation with the system's class browser, text editor, and graphics capabilities, offering insight into the pioneering work done at Xerox PARC.
This webpage documents a remarkable feat of software preservation and emulation: bringing the Xerox NoteTaker, specifically the Smalltalk-78 version of its operating environment, to life within a modern web browser. The NoteTaker, a pioneering portable computer developed by Xerox PARC in the late 1970s, represents a crucial stepping stone in the evolution of personal computing, predating even the Xerox Star. This emulator allows anyone with a web browser to experience this historically significant system firsthand, offering a glimpse into the early days of graphical user interfaces, object-oriented programming, and the very concept of a portable personal computer.
The emulation itself is based on a Smalltalk-78 virtual machine written in JavaScript, painstakingly reconstructed from original source code and documentation. This virtual machine executes the original Smalltalk-78 system image, effectively recreating the NoteTaker's software environment. The webpage provides a detailed account of the emulation process, highlighting the challenges involved in translating the intricacies of the original hardware and software into a web-compatible format. It emphasizes the importance of preserving such historical artifacts, not just for nostalgic purposes, but for understanding the evolution of computing and the innovative ideas that shaped the modern digital landscape.
The emulator offers a functional, albeit somewhat limited, representation of the NoteTaker experience. Users can interact with the graphical user interface, manipulate windows, and even experiment with Smalltalk-78 code. The webpage provides instructions on how to navigate the system, along with explanations of its core functionalities. While not perfectly replicating the original hardware's performance, the emulator provides a valuable interactive window into the past, enabling users to appreciate the ingenuity of the NoteTaker's design and the groundbreaking nature of its software. This project serves as a testament to the power of emulation in preserving and sharing historically significant software, making it accessible to a wider audience and ensuring that these important milestones in computing history are not forgotten. The detailed technical information provided on the page offers valuable insights for those interested in the history of Smalltalk, virtual machine design, and the challenges of software preservation.
