IBM PCjr
In 1983, IBM dominated the professional market with its PC. Riding high on this success, the American giant cast its eye toward home computing, a territory dominated until then by machines like the Apple II or the Commodore 64. The idea emerged to adapt the PC for families by creating a scaled-down version dubbed "Peanut" internally. Rumors multiplied in the specialized press for months until the official announcement of the PCjr on November 1st, 1983.
Expectations ran high. IBM's research budget at the time exceeded that of certain nations, and its name alone was enough to trigger public enthusiasm. The machine reused the Intel 8088 processor from the PC and maintained substantial software compatibility with its bigger sibling. This deliberate connection aimed at two objectives: reassuring buyers about the sustainability of their investment and protecting sales of the professional PC.
Two versions came to market. The base model, priced at $669, featured 64 KB of memory. The enhanced model climbed to $1,269 with its 128 KB and integrated floppy disk drive. These prices immediately positioned the machine at the high end, well above the direct competition.
The PCjr's main innovation lay in its wireless keyboard, a world first for a personal computer. The infrared connection made the machine usable from up to 6 meters away, transforming the living room into an improvised office. But this innovation came with a questionable choice: flat keys inspired by calculators, devoid of inscriptions. The symbols and letters appeared on the chassis, between the keys, complicating typing and straining the eyes.
Performance-wise, IBM equipped its machine with remarkable graphics capabilities. Several display modes coexisted, from 320×200 pixels in 4 colors to 640×200 in two shades. The enhanced model supported up to 16 simultaneous colors. Sound was equally impressive with a sophisticated circuit producing three synthesis channels over 7 octaves, complemented by a white noise generator.
Sales began in January 1984, but deliveries remained limited until March. IBM deployed unprecedented marketing firepower. Charlie Chaplin, already the PC's spokesperson, returned in television commercials. Over a hundred books appeared before the actual release, and four specialized magazines launched. Rarely had a machine benefited from such media hype.
Yet sales struggled to take off. Early reviews revealed glaring flaws. With its execution speed cut in half compared to the PC, the PCjr disappointed users accustomed to its elder's performance. Memory, capped at 128 KB, severely limited upgrade possibilities. The internal architecture made adding a second floppy drive or hard disk impossible. Proprietary connectors forced buyers to purchase overpriced adapters to connect standard peripherals.
Facing this criticism, IBM attempted to right the ship in July 1984. A new, more conventional keyboard replaced the flat-key model. Prices dropped significantly. A major promotional campaign accompanied the 1984 holiday season, temporarily boosting sales to 17% of the home market. But the upturn was short-lived: by January 1985, that figure had plummeted to 4%.
The ax fell on March 19, 1985. IBM announced the end of production, just fifteen months after commercial launch. Between 100,000 and 350,000 unsold machines piled up in warehouses. The company slashed prices on remaining stock, even giving them away to schools purchasing PCs. The bill came to $45 million in losses.
Paradoxically, this commercial failure masked some lasting successes. Sierra On-Line developed King's Quest specifically for the PCjr, revolutionizing the graphic adventure genre and launching a legendary franchise. Tandy Computer drew directly on IBM's experience to create its Model 1000, correcting the major flaws in the process: professional keyboard, performance equivalent to the PC, expansion capabilities. This Tandy 1000 achieved considerable success and extended the PCjr's technical legacy.
A community of enthusiasts keeps the memory of this unique machine alive. Expansions like the jrIDE card add a hard drive and 640 KB of memory to surviving units. The DOSBox emulator resurrects its software catalog. In Japan, IBM had attempted a variant called the JX, developed with Matsushita, but this competing project sank even deeper with only 8,000 units sold.
The PCjr story illustrates the pitfalls of a poorly executed derivative strategy. By deliberately constraining their home machine's capabilities to protect professional PC sales, IBM's engineers created a flawed product, too expensive and too limited against agile and inventive competition. Exclusive distribution through professional networks, ill-suited to the family market, sealed the fate of a venture that marked the end of IBM's ambitions in home computing.
