Editing MessagePad (section)

==Details==
===Screen and input===
With the MessagePad 120 with [[Newton OS]] 2.0, the Newton Keyboard by Apple became available, which can also be used via the dongle on Newton devices with a Newton InterConnect port, most notably the Apple MessagePad 2000/2100 series, as well as the Apple [[eMate 300]].

Newton devices featuring Newton OS 2.1 or higher can be used with the screen turned horizontally ("landscape") as well as vertically ("portrait"). A change of a setting rotates the contents of the display by 90, 180 or 270 degrees. Handwriting recognition still works properly with the display rotated, although display calibration is needed when rotation in any direction is used for the first time or when the Newton device is reset.

====Handwriting recognition====
{{Main|Newton OS}}
In initial versions (Newton OS 1.x) the handwriting recognition gave extremely mixed results for users and was sometimes inaccurate. The original handwriting recognition engine was called Calligrapher, and was licensed from a Russian company called [[:ru:Параграф (компания)|Paragraph International]]. Calligrapher's design was quite sophisticated; it attempted to learn the user's natural handwriting, using a database of known words to make guesses as to what the user was writing, and could interpret writing anywhere on the screen, whether hand-printed, in [[cursive]], or a mix of the two. By contrast, [[Palm Pilot|Palm Pilot's]] Graffiti had a less sophisticated design than Calligrapher, but was sometimes found to be more accurate and precise due to its reliance on a fixed, predefined stroke alphabet. The stroke alphabet used letter shapes which resembled standard handwriting, but which were modified to be both simple and very easy to differentiate.<ref>{{cite web |last=Miller |first=Jack |date=September 19, 1994 |title=Graffiti Arrives! -- Press Release enclosed: Palm Computing Delivers Major Advance in Handwriting RecognitionTechnology. |url=http://www.grot.com/zoomer/zoomer-list/zoomer-list-3Q1994/0048.html |url-status=live |archive-url=https://web.archive.org/web/20160627002502/http://www.grot.com/zoomer/zoomer-list/zoomer-list-3Q1994/0048.html |archive-date=June 27, 2016 |access-date=April 10, 2008 |website=3Q1994 Zoomer-List Archives, Zoomer mailing list archives, Zoomer PDA WWW Information Service |publisher=Palm Computing, Inc. |place=LOS ALTOS, Calif.}}</ref> [[Palm, Inc.|Palm Computing]] also released two versions of Graffiti for Newton devices.  The Newton version sometimes performed better and could also show strokes as they were being written as input was done on the display itself, rather than on a silkscreen area.

For editing text, Newton had a very intuitive system for handwritten editing, such as scratching out words to be deleted, circling text to be selected, or using written [[caret]]s to mark inserts.<ref>{{Cite web |date=1995 |others=PDF file created by Kady Ingham on July 16, 2001 using Acrobat Distiller 5.00 for Macintosh |title=Newton: Apple MessagePad Handbook |url=https://download.info.apple.com/Apple_Support_Area/Manuals/newton/0307258ANEWTONMP.PDF |website= |publisher=Apple Computer, Inc. |publication-place=Cupertino, CA |id=Part No. 030-7258 (listed in https://web.archive.org/web/20080406215949/http://docs.info.apple.com/article.html?artnum=50092)}}</ref>

Later releases of the [[Newton OS|Newton operating system]] retained the original recognizer for compatibility, but added a hand-printed-text-only (not [[cursive]]) recognizer, called "[[Rosetta (Newton)|Rosetta]]", which was developed by Apple, included in version 2.0 of the [[Newton OS|Newton operating system]], and refined in Newton 2.1. Rosetta is generally considered a significant improvement and many reviewers, testers, and most users consider the Newton 2.1 handwriting recognition software better than any of the alternatives even 10 years after it was introduced.<ref>HWR accuracy:

A vital feature of the Newton handwriting recognition system is the [[modeless]] [[Error detection and correction|error correction]]. That is, correction done ''[[in situ]]'' without using a separate window or widget, using a minimum of gestures. If a word is recognized improperly, the user could double-tap the word and a list of alternatives would pop up in a menu under the stylus. Most of the time, the correct word will be in the list. If not, a button at the bottom of the list allows the user to edit individual characters in that word. Other pen gestures could do such things as transpose letters (also ''[[in situ]]''). The correction popup also allowed the user to revert to the original, un-recognized letter shapes - this would be useful in note-taking scenarios if there was insufficient time to make corrections immediately. To conserve memory and storage space, alternative recognition hypotheses would not be saved indefinitely. If the user returned to a note a week later, for example, they would only see the best match. Error correction in many current handwriting systems provides such functionality but adds more steps to the process, greatly increasing the interruption to a user's workflow that a given correction requires.{{Citation needed|date=February 2008}}

====User interface====
<!-- Deleted image removed: [[File:Apple newton messagepad mixed note jk.jpg|right|thumbnail|Newton screen displaying a Note with text, "ink text", a sketch, & [[Vector graphics|vectorized]] shapes]] -->
Text could also be entered by tapping with the stylus on a small on-screen pop-up [[QWERTY]] [[virtual keyboard]], although more layouts were developed by users. Newton devices could also accept free-hand "Sketches", "Shapes", and "Ink Text", much like a desktop computer [[graphics tablet]]. 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 graphics|vector]] representations (with modifiable control points and defined vertices) of what the user was attempting to draw. "Shapes" and "Sketches" could be [[image scaling|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 [[Line wrap and word wrap|word wrap]], could be formatted to be bold, italic, etc.).<ref name=":2">{{Cite magazine |last=Huang |first=Vernon |date=December 1995 |title=First Look: Newton OS 2.0 |url=http://www.pencomputing.com/developer/newton_20.html |url-status=live |magazine=Pen Computing Magazine |issue=7 |archive-url=https://web.archive.org/web/20220330084907/http://www.pencomputing.com/developer/newton_20.html |archive-date=March 30, 2022 |access-date=January 27, 2007}}</ref> At any time a user could also direct their Newton device to recognize selected "ink text" and turn it into recognized text (deferred recognition). A Newton note (or the notes attached to each contact in Names and each Dates calendar or to-do event) could contain any mix of interleaved text, Ink Text, Shapes, and Sketches.

While the Newton offered handwriting recognition training and would clean up sketches into vector shapes, both were unreliable and required much rewriting and redrawing. The most reliable application of the Newton was collecting and organizing address and phone numbers. While handwritten messages could be stored, they could not be easily filed, sorted or searched. While the technology was a probable cause for the failure of the device (which otherwise met or exceeded expectations), the technology has been instrumental in producing the future generation of handwriting software that realizes the potential and promise that began in the development of Newton-Apple's Ink Handwriting Recognition.<ref>{{Cite web |date=June 27, 2017 |orig-date=December 6, 2007 |title=Ink: Handwriting Recognition |url=https://resources.oreilly.com/examples/9780596529529/-/blob/master/ink_handwriting_recognition.pdf |access-date=2023-09-19 |website=Supplemental Content for Mac OS X Leopard: The Missing Manual by David Pogue |publisher=O'Reilly Media, Inc. |language=en |via=GitLab}}</ref>

===Connectivity===
The MessagePad 100 series of devices used Macintosh's proprietary [[serial port]]s&mdash;round [[Mini-DIN connector|Mini-DIN 8 connectors]]. The MessagePad 2000/2100 models (as well as the eMate 300) have a small, proprietary ''Newton InterConnect'' port. However, the development of the [[Apple Newton|Newton hardware/software platform]] was canceled by [[Steve Jobs]] on February 27, 1998, so the InterConnect port, while itself very advanced, can only be used to connect a serial dongle. A prototype multi-purpose InterConnect device containing serial, audio in, audio out, and other ports was also discovered. In addition, all Newton devices have [[infrared]] connectivity, initially only the Sharp [[Amplitude-shift keying|ASK]] protocol, but later also [[IrDA]], though the Sharp ASK protocol was kept in for compatibility reasons. Unlike the Palm Pilot, all Newton devices are equipped with a standard [[PC Card]] expansion slot (two on the 2000/2100). This allows native modem and even [[Ethernet]] connectivity; Newton users have also written [[device driver|drivers]] for [[802.11b]] wireless networking cards and ATA-type [[flash memory]] cards (including the popular [[CompactFlash]] format), as well as for [[Bluetooth]] cards. Newton can also dial a phone number through the built-in speaker of the Newton device by simply holding a telephone handset up to the speaker and transmitting the appropriate tones. Fax and printing support is also built in at the operating system level, although it requires peripherals such as parallel adapters, PCMCIA cards, or serial modems, the most notable of which is the lightweight Newton Fax Modem released by Apple in 1993. It is powered by 2 AA batteries, and can also be used with a power adapter. It provides data transfer at 2,400 bit/s, and can also send and receive fax messages at 9,600 and 4,800 bit/s respectively.

===Power options===
The original Apple MessagePad and MessagePad 100 used four [[AAA battery|AAA batteries]]. They were eventually replaced by AA batteries with the release of the Apple MessagePad 110.

The use of 4 [[AA battery|AA]] [[NiCd]] (MessagePad 110, 120 and 130) and 4x AA [[NiMH]] cells (MP2x00 series, [[eMate 300]]) give a runtime of up to 30 hours (MP2100 with two 20&nbsp;MB [[Linear Flash]] memory [[PC Card]]s, no backlight usage) and up to 24 hours with backlight on. While adding more weight to the handheld Newton devices than AAA batteries or custom battery packs, the choice of an easily replaceable/rechargeable cell format gives the user a still unsurpassed runtime and flexibility of power supply. This, together with the [[flash memory]] used as internal storage starting with the Apple MessagePad 120 (if all cells lost their power, no data was lost due to the non-volatility of this storage), gave birth to the slogan "Newton never dies, it only gets new batteries".

===Later efforts and improvements===
The Apple MessagePad 2000/2100, with a vastly improved handwriting recognition system, 162&nbsp;MHz [[StrongARM]] SA-110 [[RISC]] processor, Newton OS 2.1, and a better, clearer, backlit screen, attracted critical plaudits.<ref>{{Cite web|title=SMU {{!}} World Changers Shaped Here!|url=https://www.smu.edu/|access-date=2020-10-20|website=www.smu.edu|archive-date=October 20, 2020|archive-url=https://web.archive.org/web/20201020053132/https://www.smu.edu/|url-status=live}}</ref>{{Failed verification|date=September 2023 <!-- create a separate line so pinging should work -->

====eMate 300====
{{main|eMate 300}}
[[File:Applenewton emate300.jpg|thumb|''The [[eMate 300]]'']]
The [[eMate 300]] was a Newton device in a laptop form factor offered to schools in 1997 as an inexpensive ($799 US, originally sold to education markets only) and durable computer for classroom use. However, in order to achieve its low price, the eMate 300 did not have all the speed and features of the contemporary MessagePad equivalent, the MessagePad 2000. The eMate was cancelled along with the rest of the Newton products in 1998. It is the only Newton device to use the ARM710 microprocessor (running at 25&nbsp;MHz), have an integrated keyboard, use Newton OS 2.2 (officially numbered 2.1), and its batteries are officially irreplaceable, although several users replaced them with longer-lasting ones without any damage to the eMate hardware whatsoever.

====Prototypes====
[[File:Apple Newton w Telephone (48930219127).jpg|thumb|Siemens NotePhone]]
Many prototypes of additional Newton devices were spotted. Most notable was a Newton tablet or "slate", a large, flat screen that could be written on. Others included a "Kids Newton" with side handgrips and buttons, "VideoPads" which would have incorporated a video camera and screen on their flip-top covers for two-way communications, the "Mini 2000" which would have been very similar to a Palm Pilot, and the NewtonPhone developed by [[Siemens]], which incorporated a handset and a keyboard.
