Resources was the magazine of the San Diego Macintosh User Group (SDMUG). The user group was founded by Charlie Jackson, a software developer who was also the founder of one of the first Macintosh software companies, Silicon Beach Software, best known for SuperPaint (a graphics editor) and SuperCard (an expansion on some of the concepts in Apple’s HyperCard), and Digital Darkroom, one of the first photo editing applications.
SDMUG was part of the San Diego Computer Society, but for most of its life, SDMUG was far larger than the parent. At its height, SDMUG had over 5,000 members, most in Southern California.
