High Visibility USB ASCII Keyboard-- Large Black Letters and Bright Yellow Keys! Looks like a University of Iowa computer lab item, but it's really a high-contrast, yellow on black, standard ASCII computer keyboard with very over-sized print on the keys. Perfect for Hawkeye fans, folks getting on in age, or anyone whose eyes don't work as well as they used to. Happens to all of us. Includes a 46" USB cord. Measures 17-1/4" X 5-1/4" and is for use with Windows 7, Vista, XP, 2000, Millennium edition or 98, plus MAC OS9/OSX.
