INTRODUCTION:

The Multiface was a hardware peripheral released by Romantic Robot for several 1980s home computers. The primary function of the device was to dump the computer's memory to external storage. Pressing a red button on the Multiface activated it. As most games of the era did not have a save game feature, the Multiface allowed players to save their position by saving a loadable snapshot of the game.
