Apple Newton OS

Newton OS was the operating system for the Apple Newton PDAs produced by Apple from 1993 - 1997. Newton OS was written entirely in C++ and trimmed to be low power consuming and use the available memory efficiently. Much like the first Apple Macintosh a lot of applications were written in the ROM of the Newton to save DRAM and flash space for user applications.

Features

Newton OS featured many interface elements that even the Macintosh OS didn't have at the time, such as drawers and the "poof" animation. These features were used in Mac OS X, along with Newton's Hand Writing Recognition (which is implemented as Inkwell in Mac OS X).

* Sound responsive - Clicking menus and icons makes a sound, this feature was later introduced in Mac OS 8.
* Icons - Similar to the Macintosh Desktop Metaphor, Newton OS uses icons to open applications.
* Tabbed documents - Similar to tabbed browsing in today's browsers and Apple's AtEase Interface, documents titles appear in a small tab at the top right hand of the screen.
* Rotate the screen - In Newton 2.0, the screen could be rotated to be used for drawing or word processing.
* File documents - Notes and Drawings can be categorized. Eg. Fun, Business, Personal, etc.
* Print documents - Documents on the Newton can be printed
* Send documents - Documents can be sent to another Newton via Infrared technology or sent using the Internet by E-Mail, or faxed.
* Menus - Similar to menus seen in the Macintosh OSes, but the menu titles are instead presented at the bottom of the screen, in small rectangles making them look like buttons.

oftware

Shortly after the Newton PDA's release in 1993, developers were not paying much attention to the new Newton OS API and were still more interested in developing for the Macintosh and Windows platforms. It was not until two years later that developers saw a potential market available to them in creating software for Newton OS. Several programs were made by 3rd party developers, including software to enhance Newton's initially disappointing (in OS 1.x) hand writing recognition technology.

The basic software that came with Newton OS:
* Works - A program for drawing and word processing, with all the capabilities you'd expect such as rulers, margins, page breaks, formatting, printing, spell checking and find & replace tools.
* Notes - Used for checklists, as well as both drawing and writing in the same program either with a newton keyboard or a stylus pen.
* Dates - Calendar program where you can schedule appointments and other special events.
* Names - Program for storing extensive contacts information in a flexible format.
* Formulas - Program that offers metric conversions, currency conversions, loan & mortgage calculators, etc.
* Calculator - A basic calculator with square root, percentage, MR, M+ and M- functions additional to the basic functions found on a calculator.
* Clock - A small floating window type application, known as a desktop accessory on the Macintosh. The Newton clock also included features for an alarm, minute timer and the date.

Handwriting recognition

The Newton used the CalliGrapher word-based handwriting recognition engine developed by ParaGraph International Inc.Fact|date=May 2008 The earliest versions had weaknesses that resulted in bad publicity and reviews.Fact|date=May 2008

With the release of Newton PDAs based upon version 2.0 of the OS, the handwriting recognition had substantially improved, partially being a product of ParaGraph and an Apple-created recognizer pair: Apple's Rosetta and Mondello. Newton's handwriting recognition, particularly the print recognizer, has been considered by many reviewers, testers, and users to be the best in the industry, even 10 years after it was introduced.

The Newton could recognize hand-printed text, cursive, or a mix of the two, and could also accept free-hand "Sketches", "Shapes", and "ink text". Text could also be entered by tapping with the stylus on a small on-screen pop-up QWERTY keyboard. With "Shapes", Newton could recognize that the user was attempting to draw a circle, a line, a polygon, etc, and it would clean them up into "perfect" vector representations (with modifiable control points and defined vertices) of what the user was attempting to draw. "Shapes" and "Sketches" could be scaled or deformed once drawn. "Ink text" captured the user's free-hand writing but allowed it to be treated somewhat like recognized text when manipulating for later editing purposes ("ink text" supported word wrap, could be formatted to be bold, italic, etc). [ [http://www.pencomputing.com/developer/newton_20.html Pen Computing's First Look at Newton OS 2.0] ] At any time a user could also direct the Newton to recognize selected "ink text" and turn it into recognized text (deferred recognition). A Newton Note document (or the notes attached to each contact in Names and each calendar event) could contain any mix of interleaved text, ink text, Shapes, and Sketches.

NewtonScript

Newton OS understands applications in C++, along with a user-friendly language called "NewtonScript". These applications are stored in packages. NewtonScript is as easy to use as AppleScript and contains several features that make it more powerful than AppleScript.
