, which lasted up to 28 hours on full charge. In order to achieve its low price, the eMate 300 did not have all the features of the contemporary Newton equivalent, the MessagePad 2000.

 110 RISC processor and was more expandable.

Expansion

Unlike the MessagePad line, the eMate 300 features an internal memory expansion slot. It is located in the hatch under the battery door, next to the ROM card. Both cards fit into both slots, but the ROM card is larger. The expansion card is on the left. Companies like Newertech produced cards for the eMate. Most cards expanded the data bus from 16 bits to 32 bits, as well as providing additional DRAM (program memory), and flash (storage). When one of these cards is installed, the internal DRAM is disabled, but the internal flash RAM is combined with the flash on the card. For example: If a memory card were to have 4mb of DRAM and 2mb of flash, the newton would report having 4mb of flash, and 4mb of DRAM, not 5mb of DRAM.

In addition to the expansion slot, the eMate also features a single non-CardBus PCMCIA slot. It can be used for a number of different cards, including modems, ethernet cards, wireless cards, bluetooth cards, and flash memory (linear and ATA/Compact Flash).
