Access Device 2000

Also known as the AD2000, it was primarily used by utility companies for data collection, equipment testing, and communicating over telephone lines. After development of the Newton was Steved, Access Device 2000 was replaced by a similar model that used the Windows CE operating system rather than Newton OS.
