The Garmin (originally Apollo) MX-20 is a highly specialized PC.
It runs Windows NT 4.0. If you look carefully at the datacard
you'll find a stripped down verion of Windows there (and if you
look really carefully when it boots up you'll see the kernel
startup message appear (updside down at the bottom of the screen
in the current incarnation...older versions came right side up).

The MX20 has yet to blue screen or otherwise exhibit any software
related failure.
