SoftSide

Dedicated to personal computer programming, SoftSide was a unique publication with articles and line-by-line program listings that users manually keyed in. The TRS-80 edition was first, launched in 1978. An Apple II specific version began in January 1980, followed by more individual versions supporting the Atari 8-bit computers and IBM-PC, as well as one for BASIC language programmers, Prog80. The platform-specific versions were combined into a single monthly edition in August 1980.
