Well the museum was definitely worth the trip. Most of the collection was from car manufacturers that were fully built or parts were manufactured in Pennsylvania. A lot of the cars were only manufactured a few years before they went out of business. I saw this today. It’s called a Chadwick road guide. You would purchase the machine for $95 and then you could purchase the discs for $.40 each. It would give you a turn by turn navigation. Each disc could cover 100 miles. A six disc set in the picture would get you navigation from Pottstown, PA to Easton, PA and back. The discs were inscribed with the towns along the route. As the machine would read the prepunched holes, the springs would activate the indicators in the little corner windows as to which direction the driver should take.
