Apple's documents disagree on the processor clock and the memory. The Service Source gives 27 MHz, most other Apple documents 25 MHz, and Frank Gründel's NewtTest measures 24.9 MHz.<ref name="faq" /> The Service Source gives 512K of DRAM and 512K or 1 MB of Flash, while Apple's support specification, as quoted by the Newton FAQ, gives 1 MB of DRAM and 2 MB of Flash.<ref name="ss" /><ref name="faq" /> The ROM chips are silkscreened 2.2 but report Newton OS 2.1.<ref name="faq" />

== Hardware ==
[[File:Apple eMate 300 exploded view (Service Source).png|thumb|300px|Apple's exploded view with service part numbers (Service Source, PDF p. 118)]]
Apple serviced the eMate by modules. The logic board is part of the top case assembly (661-1194); the other modules are the LCD (661-1193), the ROM card (661-1195), the keyboard (922-2398), the battery (922-2938) and the EL backlight (922-2681).<ref name="ss" /> Service diagnostics run from a PC Card, Apple part 077-0153.<ref name="ss" />

The ROM card and an optional RAM card plug into the bottom of the logic board behind the battery access door; Apple did not sell RAM cards and referred owners to other suppliers.<ref name="ss" /> Later memory upgrades for the eMate have been made by Newer Technology, Tech by Androda and NewtonSales.<ref name="faqmem">''Newton FAQ'', Part II: Hardware, B1d "Can I increase the internal memory of my Newton?", [http://newtonfaq.com/newton-faq-hardware.html newtonfaq.com] (read 2 October 2026).</ref>

The battery is a pack of four AA NiMH cells in a sleeve under the access door, wired to connector J11.<ref name="ss" /> Inside the pack are a thermistor and a temperature switch that cuts the charge current to about 100 mA above 55 °C.<ref name="fgbatt">Frank Gründel, "How to rebuild / refurbish an Apple eMate battery pack", PDA-Soft, [https://www.pda-soft.de/emate_battery_pack.html pda-soft.de/emate_battery_pack.html] (read 2 October 2026). Community guide.</ref> As on the MessagePad 2000 and 2100, a super capacitor keeps the memory and clock alive while the battery is out.<ref name="um">Apple Computer, ''eMate 300 User's Manual'', 1997. Hosted as [[:File:eMate 300 User's Manual (1997).pdf]]. Appendix A (printed pp. 243–244): a Newton Rechargeable Battery Pack and a super capacitor as backup; the charging light (green charged, orange charging, off with no adapter); one to two hours to recharge; no overcharging; battery replacement by an Apple-authorised service provider.</ref> The eMate takes the same adapters as the MessagePad; Apple's Service Source notes that the 7-watt Newton adapter charges it more slowly than the 9-watt one.<ref name="ss" />

== Common faults ==
* Hinge springs. The friction springs in the lid hinges work loose as their grease dries; a loose spring leg can pierce the display ribbon cable that runs through the hinge, killing the touchscreen or blanking lines or areas of the screen. Owners have repaired the hinges and fitted a creased washer to stop it happening again. See [[Apple eMate 300 Troubleshooting Guide#Hinge springs and the display cable|the troubleshooting guide]].<ref name="js">Joel M. Sciamma, "Repairing eMate Hinges and Display Cable", Inventors Emporium, [http://www.inventors-emporium.co.uk/pages/newton-emate-hinge.html inventors-emporium.co.uk] (read 2 October 2026).

* Battery packs. The NiMH pack wears out; Frank Gründel publishes a rebuild procedure. The Newton FAQ warns that any replacement pack's contacts must carry at least 1.2 A.<ref name="fgbatt" /><ref name="faqbatt">''Newton FAQ'', Part II: Hardware, C7 "How do I recondition or rebuild a battery pack?", [http://newtonfaq.com/newton-faq-hardware.html newtonfaq.com] (read 2 October 2026).</ref>
* Wrong adapters. A 9 V adapter has burnt out capacitor C101; Frank Gründel advises that the MAX1771 next to it (U29) may need replacing too.<ref name="fg2025">Frank Gründel, reply in "Need Assistance With Repairing eMate 300", NewtonTalk, 1 January 2025, [https://marc.info/?l=newtontalk&m=173576680331959&w=2 MARC archive].
