Photos of the first Macworld in 1985, and why Steve Jobs was a no-show FacebookTwitterEmail A scene from the first Macworld at Brooks Hall in San Francisco on Feb. 21, 1985.Steve Ringman / The Chronicle The first big Apple computer convention was introduced to San Franciscans with a $5 off clip-and-save coupon.
