When tested this keyboard lit up, indicating it getting power, and the caps and num lock keys lit up when pressed, but my test PC did not respond with any letters or numbers at all when typing. This collectible piece of electronic history has lived a long life and does show some signs of its age. Please review photos, as the item will arrive in the condition you see it in.
