Man that throws ya back! When I bit the bullet and decided to go all modern and install a “Audio reverse” deck in my car Boston was the first Cassette I put in. It was paired with a set of Mindblower speakers. Not needing to flip the tape over was just the epitome of cool. Keep in mind at that time innovation was rampant!
I had a sony deck that was auto eject,store bought cassettes with just one album,when it ejected the tape it would pop out and land on the seat. the tdk sa90’s were heavier and stay in the deck.
