On September 19, 1988, Apple introduced the Macintosh IIx, a powerful personal computer that was part of the Macintosh II series. The Macintosh IIx was designed, manufactured, and sold by Apple from 1988 to 1990, and it was considered a high-end computer at the time.
The Macintosh IIx featured a 16 MHz Motorola 68030 processor, which was a significant improvement over the Macintosh II’s 8 MHz processor. It also had a Motorola 68882 FPU coprocessor, which helped with floating-point calculations. The computer came with either 1 MB or 4 MB of RAM, a 40 MB or 80 MB hard drive, and one or two 1.44 MB floppy drives. An optional Macintosh II video card was also available.
However, despite its impressive specs, the Macintosh IIx was not a commercial success. It was discontinued on October 15, 1990, just two years after its introduction. Today, the Macintosh IIx is 34 years old and considered a vintage computer by collectors and enthusiasts.
Overall, the Macintosh IIx was a significant step forward for Apple in terms of hardware, but it did not catch on with consumers. Nevertheless, it remains a piece of computing history and a fascinating look into the evolution of personal computers.
