It was one of the most ambitious computer product announcements in history. On April 2, 1987, at twin press conferences in New York and Miami, IBM unveiled its plans to reinvent the PC industry which it had jump-started less than six years earlier with the introduction of the first IBM PC. The company introduced four new computers dubbed the PS/2 line, including an $11,000 model which it said was seven times faster than current models. The new products were rife with advanced features, including 32-bit processors, fancy graphics, 3.5″ hardshell floppy-disk drives and optical storage.
And the new hardware was accompanied by a next-generation operating system, OS/2. Co-developed by IBM and Microsoft, it was intended to replace DOS, the aging software that then powered most of the planet’s microcomputers.
