Zero for me also! I also had and Recorded music to 8-track! And I also had one of those FM receivers that you had to plug into the antenna cable. In my first car - a 1970 Ford Maverick! I think the Maverick is now a truck, or a washed up F18 Super Hornet pilot! Like another poster said, also had and used BETA when the war between VHS and BETA was happening!
