Measures approximately 18 inches long by 6 ½ inches wide by 1 ½ inches tall. I do not have the proper equipment to test this keyboard, so it is being sold as is for parts, repair, restoration or display only. I wouldn’t be surprised if it worked. Lightly to moderately dirty and dusty throughout and could use a light cleaning. Light to moderate scratching, scuffing and wear throughout from age and use. Some areas of deeper scuffing to the plastic along the front lower edge. See pictures for a better idea of condition.
