NASA Scene Generator

## Description

The _NASA Scene Generator_ was a training game for NASA employees. It featured
multiple game modes that could be loaded:

* A lunar landing simulation.
* A spaceship docking simulation.
* A shooting game in which the player controlled an airplane or helicopter and had to fire bullets at a moving tank.
* An aircraft-carrier landing simulation.
* An airport landing simulation.

The system used a color raster-scan display and made use of a joystick-like
controller.
