Newton PDA


The Newton is a series of personal digital assistants (PDAs) developed and marketed by Apple Inc., Apple Computer, Inc. An early device in the PDA category (the Newton originated the term), it was the first to feature handwriting recognition. Apple started developing the platform in 1987 and shipped the first devices in August 1993. Production officially ended on February 27, 1998. Newton devices ran on a proprietary operating system, Newton OS; examples include Apple's MessagePad series and the eMate 300, and other companies also released devices running on Newton OS. Most Newton devices were based on the ARM architecture, ARM 610 RISC processor and all featured handwriting-based input. The Newton was considered technologically innovative at its debut, but a combination of factors, some of which included its high price and early problems with its handwriting recognition feature, limited its sales. This led to Apple ultimately discontinuing the platform at the direction of Steve Jobs in 1998, a year after his return to the company.


The Newton project was a personal digital assistant platform. The PDA category did not exist for most of Newton's genesis, and the phrase "personal digital assistant" was coined relatively late in the development cycle by Apple's CEO John Sculley, the driving force behind the project. Larry Tesler determined that an advanced, low-power processor was needed for sophisticated graphics manipulation. He founded Hermann Hauser, with the ARM architecture, Acorn RISC Machine (ARM) processor, and put together Advanced RISC Machines (now ARM Holdings). When the move was made to a smaller design (designed by Jonathan Ive), the Apple Dylan, Dylan programming language, at one time intended for use with the Apple Newton (and for development of the Apple Newton operating system), was relegated to experimental status in the "Bauhaus Project" (and eventually canceled outright in 1995). Its replacement, NewtonScript, had garbage collection and tight integration with the "soup" storage and user-interface toolkit, and was specifically designed to run in environments with small RAM and large ROM. It was mostly developed by Walter Smith from 1992 to 1993. Newton used a mix of C (programming language), C/C++ and NewtonScript. Although PDAs had been developing since the original Psion Organiser in 1984,History of PDAs blog
the Newton has left one particular lasting impression: the term ''personal digital assistant'' was first coined to refer to the Newton. According to former Apple CEO John Sculley, the company invested approximately $100 million to develop Newton.

Later history and cancellation

The Newton was considered innovative at its debut, but it suffered from its high price and problems with the handwriting recognition element, its most anticipated feature. The handwriting software was barely ready by 1993 and its tendency to misread characters was widely derided in the media. This was parodied in ''The Simpsons'' episode "Lisa on Ice", where a scene makes fun of the Newton's handwriting recognition turning "Beat up Martin" into "Eat up Martha". Garry Trudeau also mocked the Newton in a weeklong arc of his comic strip ''Doonesbury'', portraying it as a costly toy that served the same function as a cheap notepad, and using its accuracy problems to humorous effect. In one panel, Michael Doonesbury's Newton misreads the words "Catching on?" as "Egg Freckles", a phrase that became widely repeated as symbolic of the Newton's problems. This phrase was subsequently included as a trigger for an Easter egg (media), easter egg in later editions of the MessagePad, producing a panel from the strip when it was entered on the device. In acknowledgement of the strip, Apple subsequently gifted a MessagePad to Trudeau. Although the software improved substantially in Newton OS 2.0, it was not enough to inspire strong sales. The Newton became popular in some industries, notably the medical field. However, the debut of the competing Palm Pilot substantially reduced its market share. Apple struggled to find a new direction for the Newton, and when Steve Jobs returned to the company in 1997, he killed the product line. He was critical of the device's weak performance, the management of the development team, and the stylus, which he disliked as it prevented the use of the fingers. He was likely also motivated by the fact that the Newton was the pet project of his old adversary John Sculley. However, Jobs saw potential in the technology and concept, if not the execution, and eventually led Apple to create its multi-touch devices inspired by FingerWorks, the iPhone and iPad.

Application software

Most Newton devices were pre-loaded with a variety of software to help in personal data organization and management. This included such applications as Notes, Names, and Dates, as well as a variety of productivity tools such as a calculator, conversion calculators (metric conversions, currency conversions, etc.), time-zone maps, etc. In later/2.x versions of the Newton OS these applications were refined, and new ones were added, such as the Works word processor and the Newton Internet Enabler, as well as the inclusion of bundled Third-party developer, 3rd party applications, such as Notion: The Newton List Manager, the QuickFigure Works spreadsheet (a "lite" version of Pelicanware's QuickFigure Pro), Pocket Quicken, the NetHopper web browser, and the EnRoute email client. Various Newton applications had full import/export capabilities with popular desktop office suite and Personal information manager, PIM (Personal Information Manager) application file formats, primarily by making use of Apple's bundled Apple Newton Software, Newton Connection Utilities (or the older Newton Connection Kit, which had been sold separately for Newton devices that used the 1.x versions of the OS).


The Notes application allowed users to create small documents that could contain text that had been typed, or that had been recognized from handwriting, as well as free-hand sketches, #User interface, "Shapes", and "ink text". In version 2.0 of the Newton OS, the Notes application (as well as Names) could accept what Apple termed "stationery", 3rd-party created plug-in modules that could extend the functionality of the basic applications. One of the new types of Notes stationery added to Newton OS 2.0 was a Hierarchy, hierarchical, Bullet point, bullet-ed, collapsible, multi-line "Checklist", an implementation of outliner software. This could be used for organizing thoughts, priorities, Time management, "to do" lists, planning steps and sub-tasks, etc. Each bullet point could contain as many lines of text as desired. A bullet point could be dragged and placed underneath another bullet point, thus forming a hierarchical outline (summary), outline/Tree structure, tree. When a bullet point was dragged, the entire sub-Tree structure, tree of child bullet points underneath it (if any) would be dragged along as well. If a bullet point had child bullet points, tapping the hollow parent bullet point once would "roll up" or collapse all the children (WindowShade, "windowshade" effect). The parent bullet point would become a solid black circle and all the children would disappear. Tapping the parent bullet point again would make the children re-appear. This functionality arrived in Newton OS 2.0, but several third parties made similar software previously for OS 1.x Newton machines, the most notable of which was Dyno Notepad, released in 1993.


The Names application was used for storing contacts. Contacts created either on the Newton device or on a Windows or Macintosh desktop Personal information manager, PIM could be synchronized to each other. Entering a date in Names for fields such as birthday or anniversary automatically created corresponding repeating events in the Dates application. Each contact had an attached free-form notes field available to it, that could contain any mix of interleaved text, ink text, Shapes, or Sketches. Like Notes, Names could be extended by developers, to create special new categories of contacts with specialized pre-defined fields. Names shipped with 3 types of contacts, "people", "companies", and "groups", but a developer could define new types, for instance "client", "patient", etc. Stand Alone Software, Inc. also created a Newton software package called the Stationery Construction Kit, which allowed users to make stationery themselves without aid of any other tools.


Dates supplied calendar, events, meeting, and alarms functions, including an integrated Time management, "to do" list manager. It offered many different display and navigation styles, including a list view, graphical day "time blocking" view, or a week, month, or year grid. As with Names and Notes, Dates items created either on the Newton or on a Windows or Macintosh desktop Personal information manager, PIM could be synchronized to each other.

Operating system and programming environment

The Newton OS consists of three layers. At the lowest level, a microkernel handles resources like Task (computers), tasks and memory. On top of the microkernel, the bulk of the operating system is implemented in C++, including the communications layer, handwriting recognition, and the NewtonScript environment. The top layer consists of built-in and user installed applications written in NewtonScript. NewtonScript is an advanced object-oriented programming language, developed by Apple employee Walter Smith (programmer), Walter Smith. Some programmers complained about the $1000 cost of the Toolbox programming environment. Additionally, it required learning a new way of programming. The Newton Toolkit (NTK), an integrated environment tailored to the graphical nature of the Newton platform, was developed specifically for developing applications for the Newton platform and included a graphical view editor, a template browser, and an interactive inspector window for debugging. Initially, it was only available for Macintosh computers, and later a Microsoft Windows version was developed. The Technical Lead for the Newton Toolkit was Norberto Menendez; other engineers on the team were Ben Sharpe and Peter Potrebic.

Data storage

Data in Newton is stored in object-oriented databases known as Soup (Apple Newton), soups. One of the innovative aspects of Newton is that soups are available to all programs; and programs can operate cross-soup; meaning that the calendar can refer to names in the address book; a note in the notepad can be converted to an appointment, and so forth; and the soups can be programmer-extended—a new address book enhancement can be built on the data from the existing address book. The soup system also made it easy to synchronize data, and the Newton Connection tools could be used for importing and exporting data. Among many file formats are the Rich Text Format, Microsoft Word, Microsoft Excel, Microsoft Works, and many more. Another consequence of the data-object soup is that objects can extend built-in applications such as the address book so seamlessly that Newton users can sometimes not distinguish which program or add-on object is responsible for the various features on their own system, because the advanced nature of Newton devices makes it easy to accept such add-ons. A user rebuilding their system after extended usage might find themselves unable to manually restore their system to the same functionality because some long-forgotten downloaded extension was missing. Data owned and used by applications and extensions themselves is tossed in the "Storage" area of the "Extras" drawer in 2.x Newton devices; on 1.x systems, they can only be found or removed in the Memory section of the built-in Prefs application, in the Card slip (also built-in), or with third-party tools such as NewtCase. There is no built-in distinction between types of data in that area. For example, an installed application's icon could be sitting right next to a database of addresses used by another installed extension further down the list. Finally, the data soup concept works well for data like addresses, which benefit from being shared cross-functionally, but it works poorly for discrete data sets like files and documents. Later, the 2.0 release of the Newton OS introduced Virtual Binary Objects to alleviate the problem of handling large data objects.

Package installation, capacity planning, and disaster recovery

Several software utilities which accommodate data transfer to and from a host system exist for the following platforms: * Classic Mac OS, Mac OS * OS X * UNIX * Linux * Microsoft Windows

Newton technology after cancellation

Before the Newton project was canceled, it was "spun off" into an Apple wholly owned subsidiary company, ''Newton Inc.'', but was reabsorbed several months later when Apple CEO Gil Amelio was fired by the board and Steve Jobs took over as then interim CEO. Two ex-Apple Newton developers founded Pixo, the company that created the operating system for the original iPod. Speculation continued for several years that Apple might release a new PDA with some Newton technology or collaborate with Palm (PDA), Palm. Feeding a bit of speculation, Apple put the "Print Recognizer" part of the Newton 2.1 handwriting recognition system into Mac OS X v10.2 (known as "Jaguar"). It can be used with graphics tablets to seamlessly input handwritten printed text anywhere there was an insertion point on the screen. This technology, known as "Inkwell (Macintosh), Inkwell", appears in the System Preferences whenever a tablet input device is plugged in. An Easter egg (virtual), Easter egg in Print Recognizer on the Newton (write "ROSETTA! ROSETTA! ROSETTA!", and the Newton will insert "ROSETTA! ROSETTA! Hey, that's me!" instead) was present in Inkwell in Mac OS 10.2 and 10.3, but seems to have been removed in 10.4. Larry Yaeger was the author of the original Rosetta recognizer on the Newton, and was also responsible for porting it to Mac OS X. The Rosetta (software), Rosetta name was later used for Apple's PowerPC software translation layer for Intel-based Macs.It has again been used to describe the Macs transition from Intel based chips to Apple Silicon M1. Some of the handwriting recognition technology from the Newton later found its way into Windows CE. The letter preferences menus showing the different ways that people write cursive characters were pixel identical on Windows CE to those previously used on the MessagePad.. At an ''All Things Digital'' conference in 2004, Steve Jobs made reference to a new "Apple PDA" (perhaps a successor to the Newton) which the company had developed but had decided not to bring to market. The tablet likely eventually evolved into the iPhone or iPad..

Newton emulation

Since 2004, the Einstein Project has been working on emulating the Newton for use as an alternative OS on other platforms. It is currently available for the Sharp Zaurus, Apple's Mac OS X, Nokia Maemo, Microsoft Windows, and the Pepper Pad 3. The emulator is an open source project, but requires an original Newton ROM to be installed in order to function. iPhones and iPads run Einstein since September 2010. The Android operating system runs Einstein since March 2011.


A possible Newton revival was at one time a common source of speculation among the Macintosh user base; when patents for a tablet based Macintosh were applied for, rumor sites jumped at the possibility of a new Tablet computer, tablet PC-style Macintosh. This later turned out to be the iPad, which currently runs Apple's proprietary iPadOS System Software. In September 2009, Michael Tchao, who pitched the original Newton concept to John Sculley, returned to Apple. Michael Tchao is now the VP of iPad Product Marketing.


Programs have been written for the Newton since its cancellation, including an RSS reader. Hardware mods made by Newton users included a board for USB connectivity, headphone jacks, and replacing the backlight with different colors.

In popular culture

The Apple Newton and its poor handwriting recognition was lampooned on the episode of ''The Simpsons'' titled "Lisa on Ice" in 1994. In the 1995 action film Under Siege 2: Dark Territory, the main character uses an Apple Newton to send an SOS message. In ''Serial Experiments Lain'', a common portable computing device, known as a HandiNavi (named after the Apple product concept, Knowledge Navigator, The Knowledge Navigator), is heavily influenced by the Newton. In the 1998 interactive movie video game The X-Files Game, the main character uses an Apple Newton to make notes, read e-mail and navigate the different locations of the game. During Apple's March 21, 2016, keynote conference, a celebration video called "40 Years in 40 Seconds" was unveiled. The video featured flashing text of names from Apple's most notable products and taglines in their forty-year history, including Newton. However, in Newton's case, it was the only name depicted in the video being explicitly scratched out, mimicking how users deleted text on the device, and referencing the full cancellation of the product line.Hackett, Stephen (March 22, 2016
