What is ATASCII?

'ATASCII' means 'Atari ASCII.' It was a character set specific to Atari's 8-bit line of computers.

The ATASCII character set contained English alphanumeric characters, plus other shapes and symbols. People would arrange these symbols on the screen to make illustrations and art.

It was also possible to create rudimentary animations by using terminal commands to move the cursor around the screen. These animations could then be saved as text files and played back later.
