ATASCII

The ATASCII character set, from ATARI Standard Code for Information Interchange, alternatively ATARI ASCII, is a character encoding used in the Atari 8-bit computers. ATASCII is based on ASCII, but is not fully compatible with it. It was first used in the Atari 400 and 800 in 1979 and was kept in all subsequent models until the line was discontinued in 1992. The Atari ST family of computers use the different Atari ST character set.

Like most other variants of ASCII, ATASCII has its own distinct characters (arrows, blocks, box-drawing characters, playing card suits, etc.) in place of the C0 control codes in ASCII (characters 0–31), as well as replacing a few other ASCII code points.
