Too cool Mojo haven't seen those tapes in years.
When I was a toddler I had a portable Fisher price unit {Walkman}. Probably took 10 C or D batteries.
Used to run around with AC/DC cranked {Pull the trigger}. And the clunky thing hung around my neck with headphones on.

Have seen recently some audiophiles talking of reel to reel, probably just as rare nowadays.
