Program description:
GPS Display is an application for Apple Newton 2.1 devices (it performs well
also on Newton MessagePad 130). Works with any NMEA 183 compatible device, connected
to the Newton through the built-in serial port or any PC Card slot.
IMPORTANT to developers: We're finishing the API for
developers. If you're developing Newton software or solutions and want to include
GPS technology into your applications contact
us.
