Christmas 1984: The Great Apple//c vs. PCjr Battle The Golden Age of Computer Sales surely must have been Christmas 1984. The Macintosh had just been released, Compaq and IBM offered powerful new CPUs, but the real action was a massive Christmas sales battle between the Apple//c and the IBM PCjr. I remember it well, I was working at ComputerLand in Los Angeles, and I was at the very center of the battle. The '84 christmas season would be an inversion of our usual high-end sales efforts. Professional computers from IBM and Compaq were too expensive for the seasonal retail market, and the Macintosh was too new and little software was available. ComputerLand was always intensely busy in December, handling christmas shoppers as well as large corporate customers who had to spend their budgets before December 31. Amidst all this flurry of year-end sales activity, Apple and IBM decided to fight it out in the low end consumer market. The Apple//c was a pretty darn good computer. It was inexpensive, with nice peripherals including a mouse, which had just made its debut on the Macintosh. The //c and the Mac casings were produced by Frog Design, so consumers got some of the cachet of the Mac even if they could only afford a //c. IBM's competition was a notorious flop, the PCjr. It had just been revamped, the "chiclet" keyboard was replaced with a better model, an inexpensive (but blurry) color monitor was standard. Microsoft produced a "sidecar" with extra memory and a Mouse, and bundled it with primitive apps like PCPaint and PFS:Write.
