Atari Program Exchange

Atari Program Exchange (APX) was a division of Atari, Inc. that distributed software for the Atari 8-bit family of home computers through a quarterly mail-order catalog. APX, the brain-child of Dale Yocum, started in February 1981 and later managed by Fred Thorlin. APX published quarterly catalogs until 1984, when Atari CEO James J. Morgan closed down the mail-order division.
