History

The first issue of the magazine was two double-sided sheets containing text printed on a Radio Shack Line Printer VII printer. Falk photocopied 25 of the debut issue, and sold them for $1.00. After the first batch sold out, he made ten more copies. The magazine's "...articles, comments, tips, and program listings..." were good enough to attract advertisements from The Micro Works and JARB Software by the release of the third issue. JARB Software (and Joe Bennett in particular) became a contributor of many
