The other popular music delivery vehicle of the time, the boom box, was essentially a technological dead-end, notwithstanding the increasingly rare beat-bumping hoopty that rolls by.
In rural areas we are contemplating taped messages from me played regularly on boom boxes set up in village centers.
It's a clunky thing, the size of a thick paperback book, with a waist strap and two ports on the front that look like miniature speakers, lending it the air of a shrunken mid-'80s boom box.
