Applications

The NEC PowerMate 286 Plus is a business-class personal computer from the mid-1980s era. These machines were used for office productivity, data entry, and general computing tasks running MS-DOS and early business software. Compatible with IBM PC/AT hardware and software standards, the system supports both 5.25" and 3.5" floppy drives for data storage and software installation.

Condition: For Parts or Not Working
This NEC PowerMate 286 Plus PM-20-100B desktop PC powers on and will boot to BIOS; however, it is being sold AS-IS for parts or repair. The system does not recognize either floppy drive. Both floppy drives — the NEC FD1157C 5.25-inch and the Panasonic JU-257 3.5-inch — were tested externally on a separate computer and confirmed working. There is no hard drive installed. The case shows age-related yellowing across most plastic surfaces, and there are a few visible cracks on the upper-right corner near the power button. All internal boards and the TDK power supply are present. Please view our photo set and contact us if you have any questions.
