NEC PC-9821CX2 CANBE Windows 3.1 MS-DOS 6.2 HDD 833MB Tested Working, Includes Keyboard and Mouse, Used. The display in the images, power cord, and RGB cable to connect to the display are not included. The keyboard was usable, but I have not checked all the keys. The mouse was usable. Sound came from the main unit's speaker. CDs and floppy disks were also read. There are scratches and stains due to the used condition. The main unit, keyboard, and mouse have discolored to a cream color due to aging. It worked, but it is a product from about 30 years ago, so please consider it as junk.
