The eMate 300 featured a 480x320 resolution

16-shade grayscale display with a backlight, a stylus pen, a full-sized keyboard, an infrared port, and standard Macintosh serial/LocalTalk ports.

Power came from built-in rechargeable batteries, 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. The eMate used a 25 MHz ARM 710a RISC processor and had less memory than the MessagePad 2000 which used a StrongARM 110 RISC processor and was more expandable.
