TRS 80 Rainbow Magazine
The Rainbow was a monthly magazine for the TRS-80 Color Computer by the Tandy Corporation (now RadioShack). It was started by the late Lawrence C. Falk (commonly known as Lonnie Falk) and was published from July 1981 to May 1993 by Falk's company, Falsoft, which was based in Prospect, Kentucky.
The first issue of the magazine was a double-sided single sheet printed on a Radio Shack 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 software and hardware articles in early issues of The Rainbow. Beginning with the first anniversary issue, the magazine was professionally typeset and had full color covers. The December 1982 issue was the first to use perfect binding.
