</ul>
<p>The Digital Ocean Tarpon and Seahorse were ruggedized Newton devices based on the MessagePad 130. Both models featured technologies such as built-in wireless networking, peer-to-peer voice communication, plus optional GPS. The Seahorse also included the first CDPD modem found in a personal digital assistant. The Tarpon was a modified and improved version of the Harris SuperTech 2000.</p>
<p>Also based on the MessagePad 130, the Harris SuperTech 2000 was designed for telecommunication field technicians, allowing them to access work orders and other information through the telephone system. The Harris Access Device 2000 was a similarly ruggedized device based on the MessagePad 2000.</p>
<p>The Motorola Marco was similar to the specifications of the MessagePad 100 and featured a wireless modem that used the Ardis wireless networking service.</p>
<p>The Sharp ExpertPad PI-7000 was equivalent to the Original MessagePad running Newton OS 1.0 or 1.1 and the ExpertPad PI-7100 was equivalent to a MessagePad 100 running Newton OS 1.3.</p>
<p>The Siemens NotePhone was developed for the German market and based on the Original MessagePad. It integrated a telephone, fax modem, and compatibility with PBX switchboards into a single package. Siemens also developed another prototype device using Newton OS called the Siemens Online Terminal.</p>
<p>See also: <a href="#IIA1l">Where can I find information about Newton prototypes?</a></p>
<p>The Schlumberger Watson was a vertical market device based on the MessagePad 2000 developed specifically for the French healthcare industry. The device included a modem and pair of smartcard readers to facilitate secure transactions such as processing claims and accessing patient records.</p>
<h5 id="IIA1c">c. Localized models</h5>
<p>The Original MessagePad with Newton OS 1.1, MessagePad 100, MessagePad 120, MessagePad 130, MessagePad 2100, and Siemens NotePhone were available in German.</p>
<p>The MessagePad 100, MessagePad 110, MessagePad 120 with Newton OS 1.3, and Schlumberger Watson were available in French.</p>
<p>The MessagePad 120, MessagePad 130, Sharp ExpertPad PI-7000, and Sharp ExpertPad PI-7100 were available in Japanese.</p>
<p>According to Carsten Lemmen:</p>
<blockquote>
“The Original MessagePad was available as a localized German model with 1.1 ROMs and factory preinstalled update to 1.11. This device could be upgraded (through a ROM replacement) to Newton OS 1.3 (equivalent to the MessagePad 100) via an Apple upgrade program in 1994. As far as I know, there was also a Japanese version of Newton OS, at least the Sharp ExpertPad was available with Japanese localization.”
</blockquote>
<h5 id="IIA1d">d. Physical differences between models</h5>
<p>Here are some quick comparisons.</p>
<p>MessagePad 100, 110, 120, and 130 devices are smaller than the MessagePad 2000 and 2100.</p>
<p>MessagePad 100, 110, 120, 130 devices and the eMate 300 are equipped with only one PCMCIA slot. MessagePad 2000 and 2100 devices have two PCMCIA slots.</p>
<p>MessagePad 130, 2000, 2100 devices and the eMate 300 are equipped with a backlight.</p>
<p>The eMate 300 is equipped with a built-in keyboard.</p>

<p id="IIA1e-6"><sup>6</sup> eMate 300 devices technically have Newton OS 2.2 installed in ROM. The physical chips on the ROM board are silkscreened with a 2.2 version number. However, the ROM was patched during manufacturing to change the version number back to 2.1, presumably to avoid confusion with the version that was installed on the MessagePad 2000. Stephanie “Maks” Maksylewich wrote about this odd backwards system patch and <a href="https://web.archive.org/web/20090312101901/http://www.felesmagus.com/newton/otheremate.html">Other eMate Hardware Hacks</a>.</p>

<p id="IIA1e-9"><sup>9</sup> MessagePad 2000, MessagePad 2100, and eMate 300 devices have a special connector known as the Newton Interconnect Port. This proprietary port can accomodate audio line in, audio line out, and two serial ports. Using a serial adapter (or dongle), the Interconnect can be converted to a standard DIN-8 serial port.<br>

<h5 id="IIA1f">f. I have a Newton model H1000. What is it?</h5>
<p>You have an Original MessagePad (OMP), the first model made, or you have an MessagePad 100, its immediate successor.</p>
<h5 id="IIA1g">g. Is Apple releasing a new Newton?</h5>
<p>Nope. This was a rumour based on rumblings that <a href="https://arstechnica.com/uncategorized/2006/02/6140-2/">Apple was interested in acquiring Palm</a> back in 2006.</p>
<h5 id="IIA1h">h. How do I tell an original MessagePad 2000 from an upgraded model?</h5>
<p>The main difference is the amount of DRAM installed in the device. To check this, tap the “i” button in Extras and select “Memory Info”. An original MessagePad 2000 will show approximately 1 MB (~916 KB) of System RAM installed. An upgraded MessagePad 2000 will show approximately 4 MB (~3,980 KB) of System RAM installed.</p>
<p>Also, if Apple upgraded the MessagePad 2000, there should be a sticker next to the Interconnect port that reads “MP2100”.</p>
<h5 id="IIA1i">i. I have a Newton NotePad. What is it?</h5>
<p>The Newton NotePad was a pre-production version of the Original MessagePad. It’s not known how (or even if) the NotePad differed from the production devices.</p>
<h5 id="IIA1j">j. I have a Newton device marked as an “EVT” or “DVT”. What is it?</h5>
<p>Pre-production prototype Newton devices were often referred to as an Engineering Verification Test or “EVT”. After EVT devices had been put through various tests and subsequently updated with changes to the hardware, a Development Verification Test or “DVT” device would be produced. DVT devices were supposedly very close to the final production devices.</p>
<p>During the development of the MessagePad 2000, an ARM 710 processor (like the one found in the eMate 300) was used in the EVT, instead of a StrongARM processor. The second round of MessagePad 2000 EVT devices (EVT 2) used the StrongARM processor.</p>
<p>Most of the MessagePad 2000 DVT devices were configured exactly the same as the production MessagePad 2000. It has been reported that a few of the DVT devices included 4 MB of DRAM instead of the standard 1 MB. Likewise, some DVT devices apparently have a special ROM board with an additional 8 MB of DRAM, bringing the total to 12 MB. There also may have been devices that used 16 MB of Flash RAM instead of the typical 8 MB of ROM.</p>
<p>Needless to say, many of these details still need to be verified.</p>
<h5 id="IIA1k">k. What makes a grey Newton Serial Adapter different from a black one?</h5>
<p>The Newton Serial Adapter is a “dongle” which converts the proprietary Interconnect port on MessagePad 2000, MessagePad 2100, and eMate 300 devices to a standard Mini DIN-8 connector.</p>
<p>There are four known variations of the adapter:</p>
<ul>
<li>Black plastic, stamped “Taiwan N 1”</li>
<li>Grey plastic, stamped “Taiwan N 2”</li>
<li>Black plastic, stamped “China N 1”</li>
<li>Black plastic, stamped “China N 2”</li>
</ul>
<p>Note that the “N” in the stamped text is actually a box with a diagonal line, not an “N” at all. At one point, it was thought that the “N 2” referred to the “N2” code name of the MessagePad 2000. It’s highly likely that this is just a coincidence, since there are “N 1” dongles as well.</p>
<p>All variations have the part number “590-0756” stamped into the plastic housing.</p>
<p>The grey version of the adapter was specific to the pre-production “DVT” (Development Verification Test) version of the MessagePad 2000.</p>
<p>The earlier “EVT” (Engineering Verification Test) devices had black adapters, just like the production version. However, between the second run of EVT devices and the DVT release, they changed one of the pins in the Interconnect port, requiring the need for different adapters.</p>
<p>Don Vollum reported that the grey adapter should be functionally and electrically identical to a black production adapter. However, this has yet to be verified.</p>
<p>Grant Hutchinson theorizes that the prototype and test versions of the dongle were manufactured in Taiwan, whereas the consumer production dongles were manufactured in China. This might explain the different text stamped into the adapters.</p>

<h4 id="IIA3">3. What is the difference between RAM, DRAM, Flash RAM, ROM, SRAM?</h4>
<p>RAM stands for Random Access Memory. It is the designation for memory that can be both written to and read. ROM stands for Read Only Memory. ROM cannot be written to. It is used in the Newton for the operating system. Hence you cannot delete it.</p>
<p>SRAM stands for Static RAM. An SRAM cell consists of a small semiconductor circuit (a flipflop), that holds one bit of information. As long as power is supplied to this flipflop, it will retain its current state (unless changed intentionally, of course), hence the back-up batteries in SRAM cards.</p>
<p>DRAM is for Dynamic RAM. A DRAM cell is constructed to be a tiny capacitor. It is much cheaper to manufacture, and can be much smaller. However, the capacitor will slowly lose it’s charge, hence the need to refresh it regularly. Also, the needed time to (un)load the capacitor in order to store a bit of information is significantly longer than the time needed to (re)set a flipflop.</p>
<p>Flash RAM is based on EEPROM technology. It’s a kind of memory that does not lose its contents when power is no longer supplied. It is used for storage on the Newton.</p>
<h4 id="IIA4">4. What are the sound capabilities of the Newton?</h4>
<p>The Original MessagePad, MessagePad 100, MessagePad 110, MessagePad 120, and MessagePad 130 support 8-bit mono audio, up to a 22,050 Hz sample rate. These devices have a small speaker located near the bottom of the device.</p>
<p>The MessagePad 2000, MessagePad 2100, and eMate 300 support 16-bit mono audio and have a slightly larger integral speaker.</p>
<p>The MessagePad 2000 and MessagePad 2100 also have a built-in microphone to support audio recording.</p>
<p>The eMate 300 has a standard 3.5 mm jack for audio output, primarily used for headphones.</p>
<p>All three of these devices can support audio line in and audio line out by using an adapter that plugs into Interconnect port.</p>
<p>See also: <a href="#IIB10">Are there any accessories that use the Interconnect port?</a></p>
<p>There are several software packages available to allow you to play and record audio.</p>

File names including the ‘sp’ designation contain specifications. File names including the ‘ba’ designation contain basic information. File names including the ‘up’ designation explain how to perform an upgrade. Manuals without an extra designation include specifications, basic information, an additional troubleshooting section, and occasionally an exploded view of the device. The eMate service manual also includes a section about the diagnostic mode, which was used with a special PC card supplied by Apple.</p>

<h4 id="IIB1">1. Storage Cards & Memory</h4>
<h5 id="IIB1a">a. What type of storage cards can I use?</h5>
<p>The Newton supports SRAM (Static RAM) and Linear Flash RAM storage cards by default.</p>
<p>SRAM cards need an internal backup battery to retain their data when not inserted in a device. Linear Flash RAM cards do not require batteries.</p>
<p>ATA-based storage cards can be used with the <a href="https://web.archive.org/web/20080701200025/http://www.kallisys.com/newton/ata/">ATA Support</a> package developed by Paul Guyot. ATA Support consists of a driver and transactional database specifically for handling these types of storage cards.</p>

<h5 id="IIB1b">b. Which storage cards are compatible with my Newton?</h5>

<p>SRAM cards are said to only work if they are 4 MB or smaller.</p>
<p>It is believed that you need Newton OS 2.x to use flash cards bigger than 4 MB, however it appears to be wrong at least with the Intel Series II+ in a MessagePad 100. Harri Hohteri succeeded in using such a card in his MessagePad 2100, MessagePad 130, and MessagePad 100.</p>
<p>It is believed that Series II+ only work in 2.x models. However, once again Harri Hohteri reported that his 40 MB card works in a MessagePad 100.</p>
<p>The maximum size limit has been said to be 4 MB, 32 MB, or any other value. Apparently, there is no size limit but the linear cards limit (64 MB), however nobody reported to have been able (or unable) to use a 64 MB card. If you do, please contact us.</p>
<p>Intel and AMD are suppliers of the chips used in these cards. Therefore Intel cards are sold under different brand names. You can identify them by their model numbers:</p>
<p>The ‘<em>nn</em>’ portion of the model number is the memory capacity (MB) of the card.</p>
<ul>
<li>Series II: iMC0<em>nn</em>FLSA</li>
<li>Series II+: iMC0<em>nn</em>FLSP</li>
<li>VS 100: iMC0<em>nn</em>FLSC</li>

<p>ATA-based storage such as the Iomega Clik!, IBM Microdrive, and CompactFlash can be used with the appropriate PCMCIA adapter and Paul Guyot’s <a href="https://web.archive.org/web/20080701200025/http://www.kallisys.com/newton/ata/">ATA Support</a> package.</p>

<h5 id="IIB1d">d. Can I increase the internal memory of my Newton?</h5>
<p>The DRAM memory of the MessagePad 2000 could be increased via the MessagePad 2100 upgrade, however Apple no longer offers this service.</p>
<p>Some third-parties sold upgrade kits and offered upgrade services, including <a href="https://web.archive.org/web/20030807200932/http://www.pixsolution.com/">PIXsolution</a> and <a href="https://web.archive.org/web/20080708205424/http://www.kc.net/~drnewton">Dave “Dr. Newton” Watson</a>. Occasionally these upgrades appear on eBay or for sale through the <a href="http://newtontalk.net/">NewtonTalk</a> mailing list.</p>
<p>Abe Lee provided instructions for a do-it-yourself <a href="https://web.archive.org/web/20010602033135/http://user.chollian.net/~cehz/frame2.htm">MessagePad 2000 upgrade</a>, although the images are unfortunately missing.</p>
<p><a href="https://androda.work/">Tech by Androda</a> currently produces <a href="https://androda.work/product/emate-dram-and-flash-upgrade/">two versions of memory upgrade</a> for the eMate 300. One version upgrades just the DRAM, providing additional System RAM. The other version upgrades both the DRAM and the internal storage.</p>
<p>At one time, you could also purchase Newer Technology’s <a href="https://web.archive.org/web/19980527040433/http://www.newerram.com/configs/emate.html">eMate 300 Memory Module</a>, which expanded both the DRAM and Flash RAM to the equivalent of an MessagePad 2100.</p>

<blockquote>
<p>“When internal DRAM memory is installed, the total amount of DRAM available will equal that on the expansion card. However, when internal flash memory is installed, the storage memory area equals the amount of original internal flash memory plus that on the internal expansion card.”</p>
<p>“For example, an expansion card with 4 MB of DRAM and 2 MB of flash memory would result in a configuration of 4 MB of DRAM and 4 MB of flash memory.”</p>
