My brother is in town and can remember when my '67 was new. He remembers our dad bringing home the car and taking the kids for a ride. He is telling me about this "smart box" that was mounted below the dash, above the console. This smart box was apparently one of the first maintenance reminder appliances produced in the automotive industry. He says that the box would spit out a chit like a polaroid picture that informed the driver about periodic maintenance items such as oil change, air filiter chage etc. I have been all over this forum for a year now and have never heard about a device like this. He remembers when the box ran out of film / paper, dad was looking in the owners manual to figure out how to refill it. Do you guys have any knowledge about a "smart box" like this. The car was a Van Nuys, late '66 build. My father bought the car in early '67 in Napa, CA.
