Found an old water damaged Swedish Kodak Proffsinfo (pro info) magazine from 1991. On page 35, there's an article about the "Professional Kodak digital system for Nikon". According to the article, "Kodak holds the World record for CCD resolution". The system, of course, featured a 1024x1526 pixel (1.3 megapixel) sensor. "The system is primarily intended for the daily press and provides high quality photos". The article also includes four DCS photos taken for Sports Illustrated by Bill Frakes at the Kentucky Derby weekend in May 1991. Enjoy!
