Colonel Decker, By Brian37 (AKA Brian James Rational Poet on FB/META and @Brianrrs37 on Twitter)

This contraption was not exactly
Part of the A Team, it would seem
More of the dead Betamax dream

Not a bar code in 1972 lava lamp abode
RS-296US, would you care to take a guess?

As to what it is, more or less, I must confess
It did do it’s best, 20 of them in a circle
In the middle a dial, numbering each slot

And for it’s time it could play a lot
No, not a juke box, but a paradox
Competing with the vinyl everyone bought

A carousel with no horses, multiple choices
The music could play for days, I was amazed

Looking back in history, at such ingenuity
Ugly duck, it never stuck a cord.
(end)

I just saw for the first time, and did not know they existed
An old 1972 CAROSEL CASSETTE TAPE DECK that held 20 cassettes. Yes, just like we had in the 80s and 90s multiple CD carousel players.

This one was the Panasonic RS-296US model. I was simply fascinated how the top of it looked like a record player, with the tinted dust cover over the tapes. But when you take it off, it looks like a round carousel but the tapes get sucked downward into the man slot when playing, then spit out upward rotated on the carousel to the next tape.
