"Introduced in March 1997, the eMate 300 was designed specifically for the education market. It was the first (and only) Newton-based machine with a keyboard, though a stylus was available as well. The eMate 300, though not particularly successful, represents Apple's first use of the translucent colored plastics that would become all hallmark of Apple's industrial design for the next few years. It shipped in a translucent aquamarine and black "clamshell" case, similar in some ways to the subsequent first-generation iBooks.
The eMate 300 ran on a 25 MHz ARM 710a processor, had 3 MB of RAM, and ran Newton OS 2.1. It had a backlit-grayscale screen similar to that of the NMP 2000, but with a landscape form factor. It also included a single PCMCIA slot and a Newton InterConnect port. The eMate 300 sold for $799 exclusively to the education sector, and was discontinued in February 1998."
