The MessagePad was the first series of personal digital assistant devices developed by Apple for the Newton platform in 1993. Some electronic engineering and the manufacture of Apple's MessagePad devices was done in Japan by the Sharp Corporation. The devices were based on the ARM 610 RISC processor and all featured handwriting recognition software and were developed and marketed by Apple. The devices ran the Newton OS.

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

User interface

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 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.). 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.

Connectivity

The MessagePad 100 series of devices used the Macintosh-standard serial ports—round 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 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 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 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 2400 bit/s, and can also send and receive fax messages at 9600 and 4800 bit/s respectively.

Power options

The original Apple MessagePad and MessagePad 100 used four AAA batteries. They were eventually replaced by AA batteries with the release of the Apple MessagePad 110.

The use of 4 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 MB Linear Flash memory PC Cards, 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 MHz StrongARM SA-110 RISC processor, Newton OS 2.1, and a better, clearer, backlit screen, attracted critical plaudits.

Cases

Apple and third parties marketed several "wallets" (cases) for the handheld Newton devices, which would hold them securely along with the owner's credit cards, driver's license, business cards, and cash. Most also protected the LCD screen.

Market reception

The original Apple MessagePad and MessagePad 100 were limited by the very short lifetime of their inadequate AAA batteries.
