Wang PC240-3 286 Desktop Computer 43MB HDD 1.2MB 5.25 Floppy 640KB RAM

The Wang PC240-3 is a low-profile 286-class desktop personal computer produced by Wang Laboratories in the late 1980s. Based on the Intel 80286 processor architecture and built to a proprietary Wang design, this machine represents Wang's entry into the IBM PC-compatible desktop market during the mid-to-late 1980s. This unit was manufactured in March 1989 at Wang's Lowell, Massachusetts facility. It is being sold as-is for parts or restoration — the hard drive is disconnected and parked, has 17 known bad sectors, no operating system is installed, and a 5.25-inch BIOS setup floppy is needed to configure settings.

Applications

Wang Laboratories was a major force in business computing through the 1970s and 1980s, best known for its word processing systems and minicomputers. By the mid-1980s, Wang introduced a line of IBM PC-compatible desktop computers — including the PC/240 series — to compete in the growing personal computer market. These machines were targeted at business and professional users and were often deployed in Wang-centric office environments alongside Wang word processors and Wang VS minicomputers. The PC/240-3, dating from early 1989, is a late-era example of Wang's 286-class desktop offerings, a generation that was already being supplanted by 386-based systems. Today these machines are sought by vintage computer collectors, Wang Laboratories enthusiasts, and restorers interested in late-1980s PC-compatible hardware history. A working 5.25-inch floppy drive and the appropriate BIOS setup disk are the key requirements for bringing this system back to life.
