I came across this magazine when searching for Bob Jervis' programming language, Parasol, he wrote a two part series about the language [1]. Jervis was the creator of Wizard C, that went on to become the compiler for the Turbo C IDE.

P.J. Plauger was the technical editor, and wrote an article in each issue, which was a quarterly. It ran from 1989 to 1995. Plauger is known as the coauthor "The Elements of Programming Style" and "Software Tools" with Brian Kernigan. [2]. He also wrote for C/C++ Users Journal.
