The VINTAGE KFC (KUO FENG CORP) 13" MONITOR is a classic piece of computing history from the Vintage Computers & Mainframes era. With its 13-inch screen size, it likely provided a small yet functional display for early computer systems. As a product from Kuo Feng Corp, a manufacturer known for producing computer hardware during the vintage computing era, this monitor would be a valuable addition to any collection of vintage computing equipment. I am not an expert on this product. This was my grandfather's, and he passed away a couple of years ago. I have tested it by turning it on, but beyond that I don't know if it's fully functional. Please be understanding if it doesn't work as expected
