Top Document: Atari 8-Bit Computers: Frequently Asked Questions

7.2) What is the ATASCII character set?
ASCII is an acronym for the American Standard Code for Information
Interchange. Pronounced ask-ee, ASCII is a code for representing English
characters as numbers, with each letter assigned a number from 0 to 127. For
example, the ASCII code for uppercase M is 77. Most computers use ASCII codes
to represent text, which makes it possible to transfer data from one computer
to another.
The 8-bit Atari computers use a modified version of the ASCII character set
called Atari ASCII, or ATASCII.
David Moeser produced this nice translation table.
Piotr Fusik corrected the description of Atari character 5.

BS = backspace DN = points down V = vertical
TB = tab key sq = square perp = perpendicular
(time) = position of hands on a clockface
Where possible, descriptions of graphics characters are taken
from standard symbols used in mathematics, weather, astronomy, etc.
Note: Different computer platforms, operating systems, programs,
printers, etc. will produce different graphics characters.
